This partially reverts a7c41b4687
Even though IORING_CLOSE_FD_AND_FILE_SLOT might save cycles for some
users, but it tries to do two things at a time and it's not clear how to
handle errors and what to return in a single result field when one part
fails and another completes well. Kill it for now.

To embrace possible future optimizations of TLS, rename zerocopy
sendfile definitions to more generic ones:
* setsockopt: TLS_TX_ZEROCOPY_SENDFILE- > TLS_TX_ZEROCOPY_RO
* sock_diag: TLS_INFO_ZC_SENDFILE -> TLS_INFO_ZC_RO_TX
RO stands for readonly and emphasizes that the application shouldn't
modify the data being transmitted with zerocopy to avoid potential
disconnection.
Fixes: c1318b39c7 ("tls: Add opt-in zerocopy mode of sendfile()")

This contains the new HTE subsystem that has been in the works for a
couple of months now. The infrastructure provided allows for drivers to
register as hardware timestamp providers, while consumers will be able
to request events that they are interested in (such as GPIOs and IRQs)
to be timestamped by the hardware providers.
Note that this currently supports only one provider, but there seems to
be enough interest in this functionality and we expect to see more
drivers added once this is merged.

This is the majority of the loongarch architecture code, including
the final system call interface and all core functionality.
It still misses three sets of peripheral but vital patches to add
support for other subsystems, which have yet to pass review:
- The drivers/firmware/efi stub for booting from a standard UEFI
firmware implementation. Both the original custom boot interface
and a draft implementation of the EFI stub did not make it, so
it is currently impossible to boot the kernel, until the
loongarch specific portions get accepted into the UEFI subsystem
- The drivers/irqchip/irq-loongson-*.c drivers are shared with the
the MIPS port, but currently lack support for ACPI based booting,
which will get merged through the irqchip subsystem.
- Similarly, the drivers/pci/controller/pci-loongson.c needs to be
modified for ACPI support, which will be merged through the
PCI subsystem.
While the port cannot actually be used before all the above are
merged, having it in 5.19 helps to establish the user space ABI
for the libc ports to build on, and to help any treewide changes
in the mainline kernel get applied here as well. A gcc-12 based
tool chains for build testing is now included in
https://mirrors.edge.kernel.org/pub/tools/crosstool/.
Original description from Huacai Chen at
https://lore.kernel.org/lkml/20220603072053.35005-1-chenhuacai@loongson.cn/:
"LoongArch is a new RISC ISA, which is a bit like MIPS or RISC-V.

Here is the large set of char, misc, and other driver subsystem updates
for 5.19-rc1. The merge request for this has been delayed as I wanted
to get lots of linux-next testing due to some late arrivals of changes
for the habannalabs driver.
Highlights of this merge are:
- habanalabs driver updates for new hardware types and fixes and
other updates
- IIO driver tree merge which includes loads of new IIO drivers
and cleanups and additions
- PHY driver tree merge with new drivers and small updates to
existing ones
- interconnect driver tree merge with fixes and updates
- soundwire driver tree merge with some small fixes
- coresight driver tree merge with small fixes and updates
- mhi bus driver tree merge with lots of updates and new device
support
- firmware driver updates
- fpga driver updates
- lkdtm driver updates (with a merge conflict, more on that
below)
- extcon driver tree merge with small updates
- lots of other tiny driver updates and fixes and cleanups, full
details in the shortlog.
All of these have been in linux-next for almost 2 weeks with no reported
problems.
Note, there are 3 merge conflicts when merging this with your tree:
- MAINTAINERS, should be easy to resolve
- drivers/slimbus/qcom-ctrl.c, should be straightforward
resolution
- drivers/misc/lkdtm/stackleak.c, not an easy resolution. This
has been noted in the linux-next tree for a while, and
resolved there, here's a link to the resolution that Stephen
came up with and that Kees says is correct:
https://lore.kernel.org/r/20220509185344.3fe1a354@canb.auug.org.au
I will be glad to provide a merge point that contains these resolutions
if that makes things any easier for you.

The {pid,uid}_t fields of struct binder_transaction were recently
replaced to use kernel types in commit 169adc2b6b ("android/binder.h:
add linux/android/binder(fs).h to UAPI compile-test coverage").
However, using __kernel_uid_t here breaks backwards compatibility in
architectures using 16-bits for this type, since glibc and some others
still expect a 32-bit uid_t. Instead, let's use __kernel_uid32_t which
avoids this compatibility problem.

Delay accounting does not track the delay of write-protect copy. When
tasks trigger many write-protect copys(include COW and unsharing of
anonymous pages[1]), it may spend a amount of time waiting for them. To
get the delay of tasks in write-protect copy, could help users to evaluate
the impact of using KSM or fork() or GUP.

Allows to read vendor statistics of a vdpa device. The specific
statistics data are received from the upstream driver in the form of an
(attribute name, attribute value) pairs.
An example of statistics for mlx5_vdpa device are:
received_desc - number of descriptors received by the virtqueue
completed_desc - number of descriptors completed by the virtqueue
A descriptor using indirect buffers is still counted as 1. In addition,
N chained descriptors are counted correctly N times as one would expect.
A new callback was added to vdpa_config_ops which provides the means for
the vdpa driver to return statistics results.
The interface allows for reading all the supported virtqueues, including
the control virtqueue if it exists.
Below are some examples taken from mlx5_vdpa which are introduced in the
following patch:
1. Read statistics for the virtqueue at index 1
$ vdpa dev vstats show vdpa-a qidx 1
vdpa-a:
queue_type tx queue_index 1 received_desc 3844836 completed_desc 3844836
2. Read statistics for the virtqueue at index 32
$ vdpa dev vstats show vdpa-a qidx 32
vdpa-a:
queue_type control_vq queue_index 32 received_desc 62 completed_desc 62
3. Read statisitics for the virtqueue at index 0 with json output
$ vdpa -j dev vstats show vdpa-a qidx 0
{"vstats":{"vdpa-a":{
"queue_type":"rx","queue_index":0,"name":"received_desc","value":417776,\
"name":"completed_desc","value":417548}}}
4. Read statistics for the virtqueue at index 0 with preety json output
$ vdpa -jp dev vstats show vdpa-a qidx 0
{
"vstats": {
"vdpa-a": {
"queue_type": "rx",
"queue_index": 0,

RFC 9131 changes default behaviour of handling RX of NA messages when the
corresponding entry is absent in the neighbour cache. The current
implementation is limited to accept just unsolicited NAs. However, the
RFC is more generic where it also accepts solicited NAs. Both types
should result in adding a STALE entry for this case.
Expand accept_untracked_na behaviour to also accept solicited NAs to
be compliant with the RFC and rename the sysctl knob to
accept_untracked_na.

One big issue with the file registration feature is that it needs user
space apps to maintain free slot info about io_uring's fixed file table,
which really is a burden for development. io_uring now supports choosing
free file slot for user space apps by using IORING_FILE_INDEX_ALLOC flag
in accept, open, and socket operations, but they need the app to use
direct accept or direct open, which not all apps are prepared to use yet.
To support apps that still need real fds, make use of the registration
feature easier. Let IORING_OP_FILES_UPDATE support choosing fixed file
slots, which will store picked fixed files slots in fd array and let cqe
return the number of slots allocated.

Pull cxl updates from Dan Williams:
"Compute Express Link (CXL) updates for this cycle.
The highlight is new driver-core infrastructure and CXL subsystem
changes for allowing lockdep to validate device_lock() usage. Thanks
to PeterZ for setting me straight on the current capabilities of the
lockdep API, and Greg acked it as well.
On the CXL ACPI side this update adds support for CXL _OSC so that
platform firmware knows that it is safe to still grant Linux native
control of PCIe hotplug and error handling in the presence of CXL
devices. A circular dependency problem was discovered between suspend
and CXL memory for cases where the suspend image might be stored in
CXL memory where that image also contains the PCI register state to
restore to re-enable the device. Disable suspend for now until an
architecture is defined to clarify that conflict.
Lastly a collection of reworks, fixes, and cleanups to the CXL
subsystem where support for snooping mailbox commands and properly
handling the "mem_enable" flow are the highlights.
Summary:
- Add driver-core infrastructure for lockdep validation of
device_lock(), and fixup a deadlock report that was previously
hidden behind the 'lockdep no validate' policy.
- Add CXL _OSC support for claiming native control of CXL hotplug and

The asm-generic tree contains three separate changes for linux-5.19:
- The h8300 architecture is retired after it has been effectively
unmaintained for a number of years. This is the last architecture we
supported that has no MMU implementation, but there are still a few
architectures (arm, m68k, riscv, sh and xtensa) that support CPUs with
and without an MMU.
- A series to add a generic ticket spinlock that can be shared by most
architectures with a working cmpxchg or ll/sc type atomic, including
the conversion of riscv, csky and openrisc. This series is also a
prerequisite for the loongarch64 architecture port that will come as
a separate pull request.
- A cleanup of some exported uapi header files to ensure they can be
included from user space without relying on other kernel headers.

There are minor updates to SoC specific drivers for chips by Rockchip,
Samsung, NVIDIA, TI, NXP, i.MX, Qualcomm, and Broadcom. Noteworthy
driver changes include:
- Several conversions of DT bindings to yaml format.
- Renesas adds driver support for R-Car V4H, RZ/V2M and RZ/G2UL SoCs.
- Qualcomm adds a bus driver for the SSC (Snapdragon Sensor Core),
and support for more chips in the RPMh power domains and the soc-id.
- NXP has a new driver for the HDMI blk-ctrl on i.MX8MP.
- Apple M1 gains support for the on-chip NVMe controller, making it
possible to finally use the internal disks. This also includes SoC
drivers for their RTKit IPC and for the SART DMA address filter.
For other subsystems that merge their drivers through the SoC tree,
we have
- Firmware drivers for the ARM firmware stack including TEE, OP-TEE,
SCMI and FF-A get a number of smaller updates and cleanups. OP-TEE
now has a cache for firmware argument structures as an optimization,
and SCMI now supports the 3.1 version of the specification.
- Reset controller updates to Amlogic, ASpeed, Renesas and ACPI drivers
- Memory controller updates for Tegra, and a few updates for other

Pull fsnotify updates from Jan Kara:
"The biggest part of this is support for fsnotify inode marks that
don't pin inodes in memory but rather get evicted together with the
inode (they are useful if userspace needs to exclude receipt of events
from potentially large subtrees using fanotify ignore marks).
There is also a fix for more consistent handling of events sent to
parent and a fix of sparse(1) complaints"

Not much dramatic changes at this time, but we've received quite
a lot of changes for ASoC, while there are still a few fixes and
quirks for usual HD- and USB-auido. Here are some highlights.
* ASoC:
- Overhaul of endianness specification for data formats, avoiding
needless restrictions due to CODECs
- Initial stages of Intel AVS driver merge
- Introduction of v4 IPC mechanism for SOF
- TDM mode support for AK4613
- Support for Analog Devices ADAU1361, Cirrus Logic CS35L45, Maxim
MAX98396, MediaTek MT8186, NXP i.MX8 micfil and SAI interfaces,
nVidia Tegra186 ASRC, and Texas Instruments TAS2764 and TAS2780
* Others
- A few regression fixes after the USB-audio endpoint management
refactoring
- More enhancements for Cirrus HD-audio codec support (still ongoing)
- Addition of generic serial MIDI driver

Commit c724c866bb ("linux/types.h: remove unnecessary __bitwise__")
was right that there are no users of __bitwise__ in the kernel, but it
turns out there are user space users of it that do expect it.
It is, after all, in the uapi directory, so user space usage is to be
expected.
Instead of reverting the commit completely, let's just clarify the
situation so that it doesn't happen again, and have some in-code
explanations for why that "__bitwise__" still exists.

Pull btrfs updates from David Sterba:
"Features:
- subpage:
- support for PAGE_SIZE > 4K (previously only 64K)
- make it work with raid56
- repair super block num_devices automatically if it does not match
the number of device items
- defrag can convert inline extents to regular extents, up to now
inline files were skipped but the setting of mount option
max_inline could affect the decision logic
- zoned:
- minimal accepted zone size is explicitly set to 4MiB
- make zone reclaim less aggressive and don't reclaim if there are
enough free zones
- add per-profile sysfs tunable of the reclaim threshold
- allow automatic block group reclaim for non-zoned filesystems, with
sysfs tunables
- tree-checker: new check, compare extent buffer owner against owner
rootid
Performance:
- avoid blocking on space reservation when doing nowait direct io
writes (+7% throughput for reads and writes)
- NOCOW write throughput improvement due to refined locking (+3%)
- send: reduce pressure to page cache by dropping extent pages right
after they're processed
Core:
- convert all radix trees to xarray
- add iterators for b-tree node items
- support printk message index
- user bulk page allocation for extent buffers
- switch to bio_alloc API, use on-stack bios where convenient, other
bio cleanups
- use rw lock for block groups to favor concurrent reads
- simplify workques, don't allocate high priority threads for all
normal queues as we need only one
- refactor scrub, process chunks based on their constraints and
similarity
- allocate direct io structures on stack and pass around only
pointers, avoids allocation and reduces potential error handling
Fixes:
- fix count of reserved transaction items for various inode
operations
- fix deadlock between concurrent dio writes when low on free data
space
- fix a few cases when zones need to be finished
VFS, iomap:
- add helper to check if sb write has started (usable for assertions)
- new helper iomap_dio_alloc_bio, export iomap_dio_bio_end_io"

Pull erofs (and fscache) updates from Gao Xiang:
"After working on it on the mailing list for more than half a year, we
finally form 'erofs over fscache' feature into shape. Hopefully it
could bring more possibility to the communities.
The story mainly started from a new project what we called "RAFS v6" [1]
for Nydus image service almost a year ago, which enhances EROFS to be
a new form of one bootstrap (which includes metadata representing the
whole fs tree) + several data-deduplicated content addressable blobs
(actually treated as multiple devices). Each blob can represent one
container image layer but not quite exactly since all new data can be
fully existed in the previous blobs so no need to introduce another
new blob.
It is actually not a new idea (at least on my side it's much like a
simpilied casync [2] for now) and has many benefits over per-file
blobs or some other exist ways since typically each RAFS v6 image only
has dozens of device blobs instead of thousands of per-file blobs.
It's easy to be signed with user keys as a golden image, transfered
untouchedly with minimal overhead over the network, kept in some type
of storage conveniently, and run with (optional) runtime verification
but without involving too many irrelevant features crossing the system
beyond EROFS itself. At least it's our final goal and we're keeping
working on it. There was also a good summary of this approach from the
casync author [3].
Regardless further optimizations, this work is almost done in the
previous Linux release cycles. In this round, we'd like to introduce
on-demand load for EROFS with the fscache/cachefiles infrastructure,
considering the following advantages:
- Introduce new file-based backend to EROFS. Although each image only
contains dozens of blobs but in densely-deployed runC host for
example, there could still be massive blobs on a machine, which is
messy if each blob is treated as a device. In contrast, fscache and
cachefiles are really great interfaces for us to make them work.
- Introduce on-demand load to fscache and EROFS. Previously, fscache
is mainly used to caching network-likewise filesystems, now it can
support on-demand downloading for local fses too with the exact
localfs on-disk format. It has many advantages which we're been
described in the latest patchset cover letter [4]. In addition to
that, most importantly, the cached data is still stored in the
original local fs on-disk format so that it's still the one signed
with private keys but only could be partially available. Users can
fully trust it during running. Later, users can also back up
cachefiles easily to another machine.
- More reliable on-demand approach in principle. After data is all
available locally, user daemon can be no longer online in some use
cases, which helps daemon crash recovery (filesystems can still in
service) and hot-upgrade (user daemon can be upgraded more
frequently due to new features or protocols introduced.)
- Other format can also be converted to EROFS filesystem format over
the internet on the fly with the new on-demand load feature and
mounted. That is entirely possible with on-demand load feature as
long as such archive format metadata can be fetched in advance like
stargz.
In addition, although currently our target user is Nydus image service [5],
but laterly, it can be used for other use cases like on-demand system
booting, etc. As for the fscache on-demand load feature itself,
strictly it can be used for other local fses too. Laterly we could
promote most code to the iomap infrastructure and also enhance it in
the read-write way if other local fses are interested.
Thanks David Howells for taking so much time and patience on this
these months, many thanks with great respect here again! Thanks Jeffle
for working on this feature and Xin Yin from Bytedance for
asynchronous I/O implementation as well as Zichen Tian, Jia Zhu, and
Yan Song for testing, much appeciated. We're also exploring more
possibly over fscache cache management over FSDAX for secure
containers and working on more improvements and useful features for
fscache, cachefiles, and on-demand load.
In addition to "erofs over fscache", NFS export and idmapped mount are
also completed in this cycle for container use cases as well.
Summary:
- Add erofs on-demand load support over fscache
- Support NFS export for erofs
- Support idmapped mounts for erofs
- Don't prompt for risk any more when using big pcluster
- Fix buffer copy overflow of ztailpacking feature
- Several minor cleanups"
