fscrypt: add Adiantum support
Add support for the Adiantum encryption mode to fscrypt. Adiantum is a
tweakable, length-preserving encryption mode with security provably
reducible to that of XChaCha12 and AES-256, subject to a security bound.
It's also a true wide-block mode, unlike XTS. See the paper
"Adiantum: length-preserving encryption for entry-level processors"
(https://eprint.iacr.org/2018/720.pdf) for more details. Also see
commit

ARM: SoC: late updates
A few updates that we merged late but are low risk for regressions for
other platforms (and a few other straggling patches):
- I mis-tagged the 'drivers' branch, and missed 3 patches. Merged in
here. They're for a driver for the PL353 SRAM controller and a build
fix for the qualcomm scm driver.
- A new platform, RDA Micro RDA8810PL (Cortex-A5 w/ integrated Vivante
GPU, 256MB RAM, Wifi). This includes some acked platform-specific
drivers (serial, etc). This also include DTs for two boards with this
SoC, OrangePi 2G and OrangePi i86.
- i.MX8 is another new platform (NXP, 4x Cortex-A53 + Cortex-M4, 4K
video playback offload). This is the first i.MX 64-bit SoC.
- Some minor updates to Samsung boards (adding a few peripherals in
DTs).
- Small rework for SMP bootup on STi platforms.
- A couple of TEE driver fixes.
- A couple of new config options (bcm2835 thermal, Uniphier MDMAC)
enabled in defconfigs.

fat: move MAX_FAT to fat.h and change it to inline function
MAX_FAT is useless in msdos_fs.h, since it uses the MSDOS_SB function that is defined in fat.h. So really, this macro can be only called from code that already includes fat.h. Hence, this patch moves it to fat.h, right after MSDOS_SB is defined. I also changed it to an inline function in order to save the double call to MSDOS_SB. This was suggested by joe@perches.com in the previous version. This patch is required for the next in the series, in which the variant (whether this is FAT12, FAT16 or FAT32) checks are replaced with new macros.

fat: remove FAT_FIRST_ENT macro
The comment edited in this patch was the only reference to the FAT_FIRST_ENT macro, which is not used anymore. Moreover, the commented line of code does not compile with the current code. Since the FAT_FIRST_ENT macro checks the FAT variant in a way that the patch series changes, I removed it, and instead wrote a clear explanation of what was checked. I verified that the changed comment is correct according to Microsoft FAT spec, search for "BPB_Media" in the following references: 1.

include/uapi/linux/msdos_fs.h: use MSDOS_NAME for volume label size
The FAT file system volume label file stored in the root directory should match the volume label field in the FAT boot sector. As consequence, the max length of these fields ought to be the same. This patch replaces the magic '11' usef in the struct fat_boot_sector with MSDOS_NAME, which is used in struct msdos_dir_entry. Please check the following references: 1. Microsoft FAT specification 2005 (http://read.pudn.com/downloads77/ebook/294884/FAT32%20Spec%20%28SDA%20Contribution%29.pdf). Search for 'volume label'. 2. Microsoft Extensible Firmware Initiative, FAT32 File System Specification (https://staff.washington.edu/dittrich/misc/fatgen103.pdf). Search for 'volume label'. 3. User space code that creates FAT filesystem sometimes uses MSDOS_NAME for the label, sometimes not. Search for 'if (memcmp(label, NO_NAME, MSDOS_NAME))'. I consider to make the same patch there as well. https://github.com/dosfstools/dosfstools/blob/master/src/mkfs.fat.c Link: http://lkml.kernel.org/r/1543096879-82837-1-git-send-email-carmeli.tamir@gmail.com Signed-off-by: Carmeli Tamir <carmeli.tamir@gmail.com> Reviewed-by: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> Reviewed-by: Johannes Thumshirn <jthumshirn@suse.de> Acked-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Cc: Jens Axboe <axboe@kernel.dk> Cc: Bart Van Assche <bvanassche@acm.org> Cc: Martin K.

Char/Misc driver patches for 4.21-rc1
Here is the big set of char and misc driver patches for 4.21-rc1.
Lots of different types of driver things in here, as this tree seems to
be the "collection of various driver subsystems not big enough to have
their own git tree" lately.
Anyway, some highlights of the changes in here:
- binderfs: is it a rule that all driver subsystems will eventually
grow to have their own filesystem? Binder now has one to handle the
use of it in containerized systems. This was discussed at the
Plumbers conference a few months ago and knocked into mergable shape
very fast by Christian Brauner. Who also has signed up to be
another binder maintainer, showing a distinct lack of good judgement :)
- binder updates and fixes
- mei driver updates
- fpga driver updates and additions
- thunderbolt driver updates
- soundwire driver updates
- extcon driver updates
- nvmem driver updates
- hyper-v driver updates
- coresight driver updates
- pvpanic driver additions and reworking for more device support
- lp driver updates. Yes really, it's _finally_ moved to the proper
parallal port driver model, something I never thought I would see
happen. Good stuff.
- other tiny driver updates and fixes.
All of these have been in linux-next for a while with no reported
issues.

This has been a fairly typical cycle, with the usual sorts of driver
updates. Several series continue to come through which improve and
modernize various parts of the core code, and we finally are starting to
get the uAPI command interface cleaned up.
- Various driver fixes for bnxt_re, cxgb3/4, hfi1, hns, i40iw, mlx4, mlx5,
qib, rxe, usnic
- Rework the entire syscall flow for uverbs to be able to run over
ioctl(). Finally getting past the historic bad choice to use write()
for command execution
- More functional coverage with the mlx5 'devx' user API
- Start of the HFI1 series for 'TID RDMA'
- SRQ support in the hns driver
- Support for new IBTA defined 2x lane widths
- A big series to consolidate all the driver function pointers into
a big struct and have drivers provide a 'static const' version of the
struct instead of open coding initialization
- New 'advise_mr' uAPI to control device caching/loading of page tables
- Support for inline data in SRPT
- Modernize how umad uses the driver core and creates cdev's and sysfs
files
- First steps toward removing 'uobject' from the view of the drivers

Pull block updates from Jens Axboe:
"This is the main pull request for block/storage for 4.21.
Larger than usual, it was a busy round with lots of goodies queued up.
Most notable is the removal of the old IO stack, which has been a long
time coming. No new features for a while, everything coming in this
week has all been fixes for things that were previously merged.
This contains:
- Use atomic counters instead of semaphores for mtip32xx (Arnd)
- Cleanup of the mtip32xx request setup (Christoph)
- Fix for circular locking dependency in loop (Jan, Tetsuo)
- bcache (Coly, Guoju, Shenghui)
* Optimizations for writeback caching
* Various fixes and improvements
- nvme (Chaitanya, Christoph, Sagi, Jay, me, Keith)
* host and target support for NVMe over TCP
* Error log page support
* Support for separate read/write/poll queues
* Much improved polling
* discard OOM fallback
* Tracepoint improvements
- lightnvm (Hans, Hua, Igor, Matias, Javier)
* Igor added packed metadata to pblk. Now drives without metadata
per LBA can be used as well.
* Fix from Geert on uninitialized value on chunk metadata reads.
* Fixes from Hans and Javier to pblk recovery and write path.
* Fix from Hua Su to fix a race condition in the pblk recovery
code.
* Scan optimization added to pblk recovery from Zhoujie.
* Small geometry cleanup from me.
- Conversion of the last few drivers that used the legacy path to
blk-mq (me)
- Removal of legacy IO path in SCSI (me, Christoph)
- Removal of legacy IO stack and schedulers (me)
- Support for much better polling, now without interrupts at all.
blk-mq adds support for multiple queue maps, which enables us to
have a map per type. This in turn enables nvme to have separate
completion queues for polling, which can then be interrupt-less.
Also means we're ready for async polled IO, which is hopefully
coming in the next release.
- Killing of (now) unused block exports (Christoph)
- Unification of the blk-rq-qos and blk-wbt wait handling (Josef)
- Support for zoned testing with null_blk (Masato)
- sx8 conversion to per-host tag sets (Christoph)
- IO priority improvements (Damien)
- mq-deadline zoned fix (Damien)
- Ref count blkcg series (Dennis)
- Lots of blk-mq improvements and speedups (me)
- sbitmap scalability improvements (me)
- Make core inflight IO accounting per-cpu (Mikulas)
- Export timeout setting in sysfs (Weiping)
- Cleanup the direct issue path (Jianchao)
- Export blk-wbt internals in block debugfs for easier debugging
(Ming)
- Lots of other fixes and improvements"

Pull btrfs updates from David Sterba:
"New features:
- swapfile support - after a long time it's here, with some
limitations where COW design does not work well with the swap
implementation (nodatacow file, no compression, cannot be
snapshotted, not possible on multiple devices, ...), as this is the
most restricted but working setup, we'll try to improve that in the
future
- metadata uuid - an optional incompat feature to assign a new
filesystem UUID without overwriting all metadata blocks, stored
only in superblock
- more balance messages are printed to system log, initial is in the
format of the command line that would be used to start it
Fixes:
- tag pages of a snapshot to better separate pages that are involved
in the snapshot (and need to get synced) from newly dirtied pages
that could slow down or even livelock the snapshot operation
- improved check of filesystem id associated with a device during
scan to detect duplicate devices that could be mixed up during
mount
- fix device replace state transitions, eg. when it ends up
interrupted and reboot tries to restart balance too, or when
start/cancel ioctls race
- fix a crash due to a race when quotas are enabled during snapshot
creation
- GFP_NOFS/memalloc_nofs_* fixes due to GFP_KERNEL allocations in
transaction context
- fix fsync of files with multiple hard links in new directories
- fix race of send with transaction commits that create snapshots
Core changes:
- cleanups:
* further removals of now-dead fsync code
* core function for finding free extent has been split and
provides a base for further cleanups to make the logic more
understandable
* removed lot of indirect callbacks for data and metadata inodes
* simplified refcounting and locking for cloned extent buffers
* removed redundant function arguments
* defines converted to enums where appropriate
- separate reserve for delayed refs from global reserve, update logic
to do less trickery and ad-hoc heuristics, move out some related
expensive operations from transaction commit or file truncate
- dev-replace switched from custom locking scheme to semaphore
- remove first phase of balance that tried to make some space for the
relocation by calling shrink and grow, this did not work as
expected and only introduced more error states due to potential
resize failures, slightly improves the runtime as the chunks on all
devices are not needlessly enumerated
- clone and deduplication now use generic helper that adds a few more
checks that were missing from the original btrfs implementation of
the ioctls"
* tag 'for-4.21-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (125 commits)
btrfs: Fix typos in comments and strings
btrfs: improve error handling of btrfs_add_link
Btrfs: use generic_remap_file_range_prep() for cloning and deduplication
btrfs: Refactor main loop in extent_readpages
btrfs: Remove 1st shrink/grow phase from balance
Btrfs: send, fix race with transaction commits that create snapshots
Btrfs: use nofs context when initializing security xattrs to avoid deadlock
btrfs: run delayed items before dropping the snapshot
btrfs: catch cow on deleting snapshots
btrfs: extent-tree: cleanup one-shot usage of @blocksize in do_walk_down
Btrfs: scrub, move setup of nofs contexts higher in the stack
btrfs: scrub: move scrub_setup_ctx allocation out of device_list_mutex
btrfs: scrub: pass fs_info to scrub_setup_ctx
btrfs: fix truncate throttling
btrfs: don't run delayed refs in the end transaction logic

btrfs: add new flushing states for the delayed refs rsv
btrfs: update may_commit_transaction to use the delayed refs rsv
btrfs: introduce delayed_refs_rsv
btrfs: only track ref_heads in delayed_ref_updates

powerpc updates for 4.21
Notable changes:
- Mitigations for Spectre v2 on some Freescale (NXP) CPUs.
- A large series adding support for pass-through of Nvidia V100 GPUs to guests
on Power9.
- Another large series to enable hardware assistance for TLB table walk on
MPC8xx CPUs.
- Some preparatory changes to our DMA code, to make way for further cleanups
from Christoph.
- Several fixes for our Transactional Memory handling discovered by fuzzing the
signal return path.
- Support for generating our system call table(s) from a text file like other
architectures.
- A fix to our page fault handler so that instead of generating a WARN_ON_ONCE,
user accesses of kernel addresses instead print a ratelimited and
appropriately scary warning.
- A cosmetic change to make our unhandled page fault messages more similar to
other arches and also more compact and informative.
- Freescale updates from Scott:
"Highlights include elimination of legacy clock bindings use from dts
files, an 83xx watchdog handler, fixes to old dts interrupt errors, and
some minor cleanup."
And many clean-ups, reworks and minor fixes etc.

Here's the main MIPS pull for Linux 4.21. Core architecture changes
include:
- Syscall tables & definitions for unistd.h are now generated by
scripts, providing greater consistency with other architectures &
making it easier to add new syscalls.
- Support for building kernels with no floating point support, upon
which any userland attempting to use floating point instructions will
receive a SIGILL. Mostly useful to shrink the kernel & as preparation
for nanoMIPS support which does not yet include FP.
- MIPS SIMD Architecture (MSA) vector register context is now exposed
by ptrace via a new NT_MIPS_MSA regset.
- ASIDs are now stored as 64b values even for MIPS32 kernels, expanding
the ASID version field sufficiently that we don't need to worry about
overflow & avoiding rare issues with reused ASIDs that have been
observed in the wild.
- The branch delay slot "emulation" page is now mapped without write
permission for the user, preventing its use as a nice location for
attacks to execute malicious code from.
- Support for ioremap_prot(), primarily to allow gdb or other
ptrace users the ability to view their tracee's memory using the same
cache coherency attribute.
- Optimizations to more cpu_has_* macros, allowing more to be
compile-time constant where possible.
- Enable building the whole kernel with UBSAN instrumentation.
- Enable building the kernel with link-time dead code & data
elimination.
Platform specific changes include:
- The Boston board gains a workaround for DMA prefetching issues with
the EG20T Platform Controller Hub that it uses.
- Cleanups to Cavium Octeon code removing about 20k lines of redundant
code, mostly unused or duplicate register definitions in headers.
- defconfig updates for the DECstation machines, including new
defconfigs for r4k & 64b machines.
- Further work on Loongson 3 support.
- DMA fixes for SiByte machines.

arm64 festive updates for 4.21
In the end, we ended up with quite a lot more than I expected: - Support for ARMv8.3 Pointer Authentication in userspace (CRIU and kernel-side support to come later) - Support for per-thread stack canaries, pending an update to GCC that is currently undergoing review - Support for kexec_file_load(), which permits secure boot of a kexec payload but also happens to improve the performance of kexec dramatically because we can avoid the sucky purgatory code from userspace. Kdump will come later (requires updates to libfdt). - Optimisation of our dynamic CPU feature framework, so that all detected features are enabled via a single stop_machine() invocation - KPTI whitelisting of Cortex-A CPUs unaffected by Meltdown, so that they can benefit from global TLB entries when KASLR is not in use - 52-bit virtual addressing for userspace (kernel remains 48-bit) - Patch in LSE atomics for per-cpu atomic operations - Custom preempt.h implementation to avoid unconditional calls to preempt_schedule() from preempt_enable() - Support for the new 'SB' Speculation Barrier instruction - Vectorised implementation of XOR checksumming and CRC32 optimisations - Workaround for Cortex-A76 erratum #1165522 - Improved compatibility with Clang/LLD - Support for TX2 system PMUS for profiling the L3 cache and DMC - Reflect read-only permissions in the linear map by default - Ensure MMIO reads are ordered with subsequent calls to Xdelay() - Initial support for memory hotplug - Tweak the threshold when we invalidate the TLB by-ASID, so that mremap() performance is improved for ranges spanning multiple PMDs. - Minor refactoring and cleanups -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABCgAGBQJcE4TmAAoJELescNyEwWM0Nr0H/iaU7/wQSzHyNXtZoImyKTul Blu2ga4/EqUrTU7AVVfmkl/3NBILWlgQVpY6tH6EfXQuvnxqD7CizbHyLdyO+z0S B5PsFUH2GLMNAi48AUNqGqkgb2knFbg+T+9IimijDBkKg1G/KhQnRg6bXX32mLJv Une8oshUPBVJMsHN1AcQknzKariuoE3u0SgJ+eOZ9yA2ZwKxP4yy1SkDt3xQrtI0 lojeRjxcyjTP1oGRNZC+BWUtGOT35p7y6cGTnBd/4TlqBGz5wVAJUcdoxnZ6JYVR O8+ob9zU+4I0+SKt80s7pTLqQiL9rxkKZ5joWK1pr1g9e0s5N5yoETXKFHgJYP8= =sYdt -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 festive updates from Will Deacon: "In the end, we ended up with quite a lot more than I expected: - Support for ARMv8.3 Pointer Authentication in userspace (CRIU and kernel-side support to come later) - Support for per-thread stack canaries, pending an update to GCC that is currently undergoing review - Support for kexec_file_load(), which permits secure boot of a kexec payload but also happens to improve the performance of kexec dramatically because we can avoid the sucky purgatory code from userspace.

sound updates for 4.21
There are no intensive changes in both ALSA and ASoC core parts while
rather most of changes are a bunch of driver fixes and updates.
A large diff pattern appears in ASoC TI part which now merges both
OMAP and DaVinci stuff, but the rest spreads allover the places.
Note that this pull request includes also some updates for LED trigger
and platform drivers for mute LEDs, appearing in the diffstat as well.
Some highlights:
ASoC:
- Preparatory work for merging the audio-graph and audio-graph-scu
cards
- A merge of TI OMAP and DaVinci directories, as both product lines
get merged together. Also including a few architecture changes as
well.
- Major cleanups of the Maxim MAX9867 driver
- Small fixes for tablets & co with Intel BYT/CHT chips
- Lots of rsnd updates as usual
- Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S
controllers
HD-audio:
- Introduce audio-mute LED trigger for replacing the former hackish
dynamic binding
- Huawei WMI hotkey and mute LED support
- Refactoring of PM code and display power controls
- Headset button support in the generic jack code
- A few updates for Tegra
- Fixups for HP EliteBook and ASUS UX391UA
- Lots of updates for Intel ASoC HD-audio, including the improved DSP
detection and the fallback binding from ASoC SST to legacy HD-audio
controller drivers
Others:
- Updates for FireWire TASCAM and Fireface devices, some other fixes
- A few potential Spectre v1 fixes that are all trivial

vfio_pci: Add NVIDIA GV100GL [Tesla V100 SXM2] subdriver
POWER9 Witherspoon machines come with 4 or 6 V100 GPUs which are not pluggable PCIe devices but still have PCIe links which are used for config space and MMIO. In addition to that the GPUs have 6 NVLinks which are connected to other GPUs and the POWER9 CPU. POWER9 chips have a special unit on a die called an NPU which is an NVLink2 host bus adapter with p2p connections to 2 to 3 GPUs, 3 or 2 NVLinks to each. These systems also support ATS (address translation services) which is a part of the NVLink2 protocol. Such GPUs also share on-board RAM (16GB or 32GB) to the system via the same NVLink2 so a CPU has cache-coherent access to a GPU RAM. This exports GPU RAM to the userspace as a new VFIO device region. This preregisters the new memory as device memory as it might be used for DMA. This inserts pfns from the fault handler as the GPU memory is not onlined until the vendor driver is loaded and trained the NVLinks so doing this earlier causes low level errors which we fence in the firmware so it does not hurt the host system but still better be avoided; for the same reason this does not map GPU RAM into the host kernel (usual thing for emulated access otherwise). This exports an ATSD (Address Translation Shootdown) register of NPU which allows TLB invalidations inside GPU for an operating system. The register conveniently occupies a single 64k page. It is also presented to the userspace as a new VFIO device region. One NPU has 8 ATSD registers, each of them can be used for TLB invalidation in a GPU linked to this NPU. This allocates one ATSD register per an NVLink bridge allowing passing up to 6 registers. Due to the host firmware bug (just recently fixed), only 1 ATSD register per NPU was actually advertised to the host system so this passes that alone register via the first NVLink bridge device in the group which is still enough as QEMU collects them all back and presents to the guest via vPHB to mimic the emulated NPU PHB on the host. In order to provide the userspace with the information about GPU-to-NVLink connections, this exports an additional capability called "tgt" (which is an abbreviated host system bus address). The "tgt" property tells the GPU its own system address and allows the guest driver to conglomerate the routing information so each GPU knows how to get directly to the other GPUs. For ATS to work, the nest MMU (an NVIDIA block in a P9 CPU) needs to know LPID (a logical partition ID or a KVM guest hardware ID in other words) and PID (a memory context ID of a userspace process, not to be confused with a linux pid). This assigns a GPU to LPID in the NPU and this is why this adds a listener for KVM on an IOMMU group. A PID comes via NVLink from a GPU and NPU uses a PID wildcard to pass it through. This requires coherent memory and ATSD to be available on the host as the GPU vendor only supports configurations with both features enabled and other configurations are known not to work. Because of this and because of the ways the features are advertised to the host system (which is a device tree with very platform specific properties), this requires enabled POWERNV platform. The V100 GPUs do not advertise any of these capabilities via the config space and there are more than just one device ID so this relies on the platform to tell whether these GPUs have special abilities such as NVLinks.
