fuse: Rename DIRECT_IO_RELAX to DIRECT_IO_ALLOW_MMAP
Although DIRECT_IO_RELAX's initial usage is to allow shared mmap, its
description indicates a purpose of reducing memory footprint. This
may imply that it could be further used to relax other DIRECT_IO
operations in the future.
Replace it with a flag DIRECT_IO_ALLOW_MMAP which does only one thing,
allow shared mmap of DIRECT_IO files while still bypassing the cache
on regular reads and writes.
[Miklos] Also Keep DIRECT_IO_RELAX definition for backward compatibility.

uapi: propagate __struct_group() attributes to the container union
Recently the kernel test robot has reported an ARM-specific BUILD_BUG_ON()
in an old and unmaintained wil6210 wireless driver. The problem comes from
the structure packing rules of old ARM ABI ('-mabi=apcs-gnu'). For example,
the following structure is packed to 18 bytes instead of 16:
struct poorly_packed {
unsigned int a;
unsigned int b;
unsigned short c;
union {
struct {
unsigned short d;
unsigned int e;
} __attribute__((packed));
struct {
unsigned short d;
unsigned int e;
} __attribute__((packed)) inner;
};
} __attribute__((packed));
To fit it into 16 bytes, it's required to add packed attribute to the
container union as well:
struct poorly_packed {
unsigned int a;
unsigned int b;
unsigned short c;
union {
struct {
unsigned short d;
unsigned int e;
} __attribute__((packed));
struct {
unsigned short d;
unsigned int e;
} __attribute__((packed)) inner;
} __attribute__((packed));
} __attribute__((packed));
Thanks to Andrew Pinski of GCC team for sorting the things out at
https://gcc.gnu.org/pipermail/gcc/2023-November/242888.html.

Pull vfs fixes from Christian Brauner:
- Avoid calling back into LSMs from vfs_getattr_nosec() calls.
IMA used to query inode properties accessing raw inode fields without
dedicated helpers. That was finally fixed a few releases ago by
forcing IMA to use vfs_getattr_nosec() helpers.
The goal of the vfs_getattr_nosec() helper is to query for attributes
without calling into the LSM layer which would be quite problematic
because incredibly IMA is called from __fput()...
__fput()
-> ima_file_free()
What it does is to call back into the filesystem to update the file's
IMA xattr. Querying the inode without using vfs_getattr_nosec() meant
that IMA didn't handle stacking filesystems such as overlayfs
correctly. So the switch to vfs_getattr_nosec() is quite correct. But
the switch to vfs_getattr_nosec() revealed another bug when used on
stacking filesystems:
__fput()
-> ima_file_free()
-> vfs_getattr_nosec()
-> i_op->getattr::ovl_getattr()
-> vfs_getattr()
-> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr()
-> security_inode_getattr() # calls back into LSMs
Now, if that __fput() happens from task_work_run() of an exiting task
current->fs and various other pointer could already be NULL. So
anything in the LSM layer relying on that not being NULL would be
quite surprised.
Fix that by passing the information that this is a security request
through to the stacking filesystem by adding a new internal
ATT_GETATTR_NOSEC flag. Now the callchain becomes:
__fput()
-> ima_file_free()
-> vfs_getattr_nosec()
-> i_op->getattr::ovl_getattr()
-> if (AT_GETATTR_NOSEC)
vfs_getattr_nosec()
else
vfs_getattr()
-> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr()
- Fix a bug introduced with the iov_iter rework from last cycle.
This broke /proc/kcore by copying too much and without the correct
offset.
- Add a missing NULL check when allocating the root inode in
autofs_fill_super().
- Fix stable writes for multi-device filesystems (xfs, btrfs etc) and
the block device pseudo filesystem.
Stable writes used to be a superblock flag only, making it a per
filesystem property. Add an additional AS_STABLE_WRITES mapping flag
to allow for fine-grained control.
- Ensure that offset_iterate_dir() returns 0 after reaching the end of
a directory so it adheres to getdents() convention.
* tag 'vfs-6.7-rc3.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
libfs: getdents() should return 0 after reaching EOD
xfs: respect the stable writes flag on the RT device
xfs: clean up FS_XFLAG_REALTIME handling in xfs_ioctl_setattr_xflags

filemap: add a per-mapping stable writes flag

fs: Pass AT_GETATTR_NOSEC flag to getattr interface function
When vfs_getattr_nosec() calls a filesystem's getattr interface function
then the 'nosec' should propagate into this function so that
vfs_getattr_nosec() can again be called from the filesystem's gettattr
rather than vfs_getattr(). The latter would add unnecessary security
checks that the initial vfs_getattr_nosec() call wanted to avoid.
Therefore, introduce the getattr flag GETATTR_NOSEC and allow to pass
with the new getattr_flags parameter to the getattr interface function.
In overlayfs and ecryptfs use this flag to determine which one of the
two functions to call.
In a recent code change introduced to IMA vfs_getattr_nosec() ended up
calling vfs_getattr() in overlayfs, which in turn called
security_inode_getattr() on an exiting process that did not have
current->fs set anymore, which then caused a kernel NULL pointer
dereference. With this change the call to security_inode_getattr() can
be avoided, thus avoiding the NULL pointer dereference.

media: v4l2-subdev: Fix a 64bit bug
The problem is this line here from subdev_do_ioctl().
client_cap->capabilities &= ~V4L2_SUBDEV_CLIENT_CAP_STREAMS;
The "client_cap->capabilities" variable is a u64. The AND operation
is supposed to clear out the V4L2_SUBDEV_CLIENT_CAP_STREAMS flag. But
because it's a 32 bit variable it accidentally clears out the high 32
bits as well.
Currently we only use the first bit and none of the upper bits so this
doesn't affect runtime behavior.

btrfs: make OWNER_REF_KEY type value smallest among inline refs
BTRFS_EXTENT_OWNER_REF_KEY is the type of simple quotas extent owner
refs. This special inline ref goes in front of all other inline refs.
In general, inline refs have a required sorted order s.t. type never
decreases (among other requirements). This was recently reified into a
tree-checker and fsck rule, which broke simple quotas. To be fair,
though, in a sense, the new owner ref item had also violated that not
yet fully enforced requirement.
This fix brings the owner ref item into compliance with the requirement
that inline ref type never decrease.
btrfs/301 exercises this behavior and should pass again with this fix.

Pull unified attestation reporting from Dan Williams:
"In an ideal world there would be a cross-vendor standard attestation
report format for confidential guests along with a common device
definition to act as the transport.
In the real world the situation ended up with multiple platform
vendors inventing their own attestation report formats with the
SEV-SNP implementation being a first mover to define a custom
sev-guest character device and corresponding ioctl(). Later, this
configfs-tsm proposal intercepted an attempt to add a tdx-guest
character device and a corresponding new ioctl(). It also anticipated
ARM and RISC-V showing up with more chardevs and more ioctls().
The proposal takes for granted that Linux tolerates the vendor report
format differentiation until a standard arrives. From talking with
folks involved, it sounds like that standardization work is unlikely
to resolve anytime soon. It also takes the position that kernfs ABIs
are easier to maintain than ioctl(). The result is a shared configfs
mechanism to return per-vendor report-blobs with the option to later
support a standard when that arrives.
Part of the goal here also is to get the community into the
"uncomfortable, but beneficial to the long term maintainability of the
kernel" state of talking to each other about their differentiation and
opportunities to collaborate. Think of this like the device-driver
equivalent of the common memory-management infrastructure for
confidential-computing being built up in KVM.
As for establishing an "upstream path for cross-vendor
confidential-computing device driver infrastructure" this is something
I want to discuss at Plumbers. At present, the multiple vendor
proposals for assigning devices to confidential computing VMs likely
needs a new dedicated repository and maintainer team, but that is a
discussion for v6.8.
For now, Greg and Thomas have acked this approach and this is passing
is AMD, Intel, and Google tests.
Summary:
- Introduce configfs-tsm as a shared ABI for confidential computing
attestation reports
- Convert sev-guest to additionally support configfs-tsm alongside
its vendor specific ioctl()
- Added signed attestation report retrieval to the tdx-guest driver
forgoing a new vendor specific ioctl()
- Misc cleanups and a new __free() annotation for kvfree()"

USB/Thunderbolt changes for 6.7-rc1
Here is the "big" set of USB and Thunderbolt changes for 6.7-rc1.
Nothing really major in here, just lots of constant development for new
hardware. Included in here are:
- Thunderbolt (i.e. USB4) fixes for reported issues and support for
new hardware types and devices
- USB typec additions of new drivers and cleanups for some existing
ones
- xhci cleanups and expanded tracing support and some platform
specific updates
- USB "La Jolla Cove Adapter (LJCA)" support added, and the gpio, spi,
and i2c drivers for that type of device (all acked by the respective
subsystem maintainers.)
- lots of USB gadget driver updates and cleanups
- new USB dwc3 platforms supported, as well as other dwc3 fixes and
cleanups
- USB chipidea driver updates
- other smaller driver cleanups and additions, full details in the
shortlog
All of these have been in the linux-next tree for a while with no
reported problems, EXCEPT for some merge conflicts that you will run
into in your tree. 2 of them are in device-tree files, which will be
trivial to resolve (accept both sides), and the last in the
drivers/gpio/gpio-ljca.c file, in the remove callback, resolution should
be pretty trivial (take the version in this branch), see here:
https://lore.kernel.org/all/20231016134159.11d8f849@canb.auug.org.au/
for details, or I can provide a resolved merge point if needed.

The related patch series has been reviewed for almost two years, it has evolved a lot and we now have reached a decent design, code and testing.

Test coverage for security/landlock is 92.4% of 710 lines according to gcc/gcov-13, and it was 93.1% of 597 lines before this series.

Tracing updates for v6.7:
- Remove eventfs_file descriptor This is the biggest change, and the second part of making eventfs create its files dynamically. In 6.6 the first part was added, and that maintained a one to one mapping between eventfs meta descriptors and the directories and file inodes and dentries that were dynamically created. The directories were represented by a eventfs_inode and the files were represented by a eventfs_file. In v6.7 the eventfs_file is removed. As all events have the same directory make up (sched_switch has an "enable", "id", "format", etc files), the handing of what files are underneath each leaf eventfs directory is moved back to the tracing subsystem via a callback. When a event is added to the eventfs, it registers an array of evenfs_entry's. These hold the names of the files and the callbacks to call when the file is referenced. The callback gets the name so that the same callback may be used by multiple files. The callback then supplies the filesystem_operations structure needed to create this file. This has brought the memory footprint of creating multiple eventfs instances down by 2 megs each! - User events now has persistent events that are not associated to a single processes. These are privileged events that hang around even if no process is attached to them. - Clean up of seq_buf. There's talk about using seq_buf more to replace strscpy() and friends. But this also requires some minor modifications of seq_buf to be able to do this. - Expand instance ring buffers individually Currently if boot up creates an instance, and a trace event is enabled on that instance, the ring buffer for that instance and the top level ring buffer are expanded (1.4 MB per CPU). This wastes memory as this happens when nothing is using the top level instance. - Other minor clean ups and fixes. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZUMrBBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6quzVAQCed/kPM7X9j2QZamJVDruMf2CmVxpu /TOvKvSKV584GgEAxLntf5VKx1Q98bc68y3Zkg+OCi8jSgORos1ROmURhws= =iIgb -----END PGP SIGNATURE----- Merge tag 'trace-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing updates from Steven Rostedt: - Remove eventfs_file descriptor This is the biggest change, and the second part of making eventfs create its files dynamically.

ARM:
* Generalized infrastructure for 'writable' ID registers, effectively
allowing userspace to opt-out of certain vCPU features for its guest
* Optimization for vSGI injection, opportunistically compressing MPIDR
to vCPU mapping into a table
* Improvements to KVM's PMU emulation, allowing userspace to select
the number of PMCs available to a VM
* Guest support for memory operation instructions (FEAT_MOPS)
* Cleanups to handling feature flags in KVM_ARM_VCPU_INIT, squashing
bugs and getting rid of useless code
* Changes to the way the SMCCC filter is constructed, avoiding wasted
memory allocations when not in use
* Load the stage-2 MMU context at vcpu_load() for VHE systems, reducing
the overhead of errata mitigations
* Miscellaneous kernel and selftest fixes
LoongArch:
* New architecture. The hardware uses the same model as x86, s390
and RISC-V, where guest/host mode is orthogonal to supervisor/user
mode. The virtualization extensions are very similar to MIPS,
therefore the code also has some similarities but it's been cleaned
up to avoid some of the historical bogosities that are found in
arch/mips. The kernel emulates MMU, timer and CSR accesses, while
interrupt controllers are only emulated in userspace, at least for
now.
RISC-V:
* Support for the Smstateen and Zicond extensions
* Support for virtualizing senvcfg
* Support for virtualized SBI debug console (DBCN)
S390:
* Nested page table management can be monitored through tracepoints
and statistics
x86:
* Fix incorrect handling of VMX posted interrupt descriptor in KVM_SET_LAPIC,
which could result in a dropped timer IRQ
* Avoid WARN on systems with Intel IPI virtualization
* Add CONFIG_KVM_MAX_NR_VCPUS, to allow supporting up to 4096 vCPUs without
forcing more common use cases to eat the extra memory overhead.
* Add virtualization support for AMD SRSO mitigation (IBPB_BRTYPE and
SBPB, aka Selective Branch Predictor Barrier).
* Fix a bug where restoring a vCPU snapshot that was taken within 1 second of
creating the original vCPU would cause KVM to try to synchronize the vCPU's
TSC and thus clobber the correct TSC being set by userspace.
* Compute guest wall clock using a single TSC read to avoid generating an
inaccurate time, e.g. if the vCPU is preempted between multiple TSC reads.
* "Virtualize" HWCR.TscFreqSel to make Linux guests happy, which complain
about a "Firmware Bug" if the bit isn't set for select F/M/S combos.
Likewise "virtualize" (ignore) MSR_AMD64_TW_CFG to appease Windows Server
2022.
* Don't apply side effects to Hyper-V's synthetic timer on writes from
userspace to fix an issue where the auto-enable behavior can trigger
spurious interrupts, i.e. do auto-enabling only for guest writes.
* Remove an unnecessary kick of all vCPUs when synchronizing the dirty log
without PML enabled.
* Advertise "support" for non-serializing FS/GS base MSR writes as appropriate.
* Harden the fast page fault path to guard against encountering an invalid
root when walking SPTEs.
* Omit "struct kvm_vcpu_xen" entirely when CONFIG_KVM_XEN=n.
* Use the fast path directly from the timer callback when delivering Xen
timer events, instead of waiting for the next iteration of the run loop.
This was not done so far because previously proposed code had races,
but now care is taken to stop the hrtimer at critical points such as
restarting the timer or saving the timer information for userspace.
* Follow the lead of upstream Xen and ignore the VCPU_SSHOTTMR_future flag.
* Optimize injection of PMU interrupts that are simultaneous with NMIs.
* Usual handful of fixes for typos and other warts.
x86 - MTRR/PAT fixes and optimizations:
* Clean up code that deals with honoring guest MTRRs when the VM has
non-coherent DMA and host MTRRs are ignored, i.e. EPT is enabled.
* Zap EPT entries when non-coherent DMA assignment stops/start to prevent
using stale entries with the wrong memtype.
* Don't ignore guest PAT for CR0.CD=1 && KVM_X86_QUIRK_CD_NW_CLEARED=y.
This was done as a workaround for virtual machine BIOSes that did not
bother to clear CR0.CD (because ancient KVM/QEMU did not bother to
set it, in turn), and there's zero reason to extend the quirk to
also ignore guest PAT.
x86 - SEV fixes:
* Report KVM_EXIT_SHUTDOWN instead of EINVAL if KVM intercepts SHUTDOWN while
running an SEV-ES guest.
* Clean up the recognition of emulation failures on SEV guests, when KVM would
like to "skip" the instruction but it had already been partially emulated.
This makes it possible to drop a hack that second guessed the (insufficient)
information provided by the emulator, and just do the right thing.
Documentation:
* Various updates and fixes, mostly for x86
* MTRR and PAT fixes and optimizations:

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Use acpi_evaluate_dsm_typed() instead of open-coding _DSM
evaluation to learn device characteristics (Andy Shevchenko)
- Tidy multi-function header checks using new PCI_HEADER_TYPE_MASK
definition (Ilpo Järvinen)
- Simplify config access error checking in various drivers (Ilpo
Järvinen)
- Use pcie_capability_clear_word() (not
pcie_capability_clear_and_set_word()) when only clearing (Ilpo
Järvinen)
- Add pci_get_base_class() to simplify finding devices using base
class only (ignoring subclass and programming interface) (Sui
Jingfeng)
- Add pci_is_vga(), which includes ancient PCI_CLASS_NOT_DEFINED_VGA
devices from before the Class Code was added to PCI (Sui Jingfeng)
- Use pci_is_vga() for vgaarb, sysfs "boot_vga", virtio, qxl to
include ancient VGA devices (Sui Jingfeng)
Resource management:
- Make pci_assign_unassigned_resources() non-init because sparc uses
it after init (Randy Dunlap)
Driver binding:
- Retain .remove() and .probe() callbacks (previously __init) because
sysfs may cause them to be called later (Uwe Kleine-König)
- Prevent xHCI driver from claiming AMD VanGogh USB3 DRD device, so
it can be claimed by dwc3 instead (Vicki Pfau)
PCI device hotplug:
- Add Ampere Altra Attention Indicator extension driver for acpiphp
(D Scott Phillips)
Power management:
- Quirk VideoPropulsion Torrent QN16e with longer delay after reset
(Lukas Wunner)
- Prevent users from overriding drivers that say we shouldn't use
D3cold (Lukas Wunner)
- Avoid PME from D3hot/D3cold for AMD Rembrandt and Phoenix USB4
because wakeup interrupts from those states don't work if amd-pmc
has put the platform in a hardware sleep state (Mario Limonciello)
IOMMU:
- Disable ATS for Intel IPU E2000 devices with invalidation message
endianness erratum (Bartosz Pawlowski)
Error handling:
- Factor out interrupt enable/disable into helpers (Kai-Heng Feng)
Peer-to-peer DMA:
- Fix flexible-array usage in struct pci_p2pdma_pagemap in case we
ever use pagemaps with multiple entries (Gustavo A. R. Silva)
ASPM:
- Revert a change that broke when drivers disabled L1 and users later
enabled an L1.x substate via sysfs, and fix a similar issue when
users disabled L1 via sysfs (Heiner Kallweit)
Endpoint framework:
- Fix double free in __pci_epc_create() (Dan Carpenter)
- Use IS_ERR_OR_NULL() to simplify endpoint core (Ruan Jinjie)
Cadence PCIe controller driver:
- Drop unused "is_rc" member (Li Chen)
Freescale Layerscape PCIe controller driver:
- Enable 64-bit addressing in endpoint mode (Guanhua Gao)
Intel VMD host bridge driver:
- Fix multi-function header check (Ilpo Järvinen)
Microsoft Hyper-V host bridge driver:
- Annotate struct hv_dr_state with __counted_by (Kees Cook)
NVIDIA Tegra194 PCIe controller driver:
- Drop setting of LNKCAP_MLW (max link width) since dw_pcie_setup()
already does this via dw_pcie_link_set_max_link_width() (Yoshihiro
Shimoda)
Qualcomm PCIe controller driver:
- Use PCIE_SPEED2MBS_ENC() to simplify encoding of link speed
(Manivannan Sadhasivam)
- Add a .write_dbi2() callback so DBI2 register writes, e.g., for
setting the BAR size, work correctly (Manivannan Sadhasivam)
- Enable ASPM for platforms that use 1.9.0 ops, because the PCI core
doesn't enable ASPM states that haven't been enabled by the
firmware (Manivannan Sadhasivam)
Renesas R-Car Gen4 PCIe controller driver:
- Add DesignWare core support (set max link width, EDMA_UNROLL flag,
.pre_init(), .deinit(), etc) for use by R-Car Gen4 driver
(Yoshihiro Shimoda)
- Add driver and DT schema for DesignWare-based Renesas R-Car Gen4
controller in both host and endpoint mode (Yoshihiro Shimoda)
Xilinx NWL PCIe controller driver:
- Update ECAM size to support 256 buses (Thippeswamy Havalige)
- Stop setting bridge primary/secondary/subordinate bus numbers,
since PCI core does this (Thippeswamy Havalige)
Xilinx XDMA controller driver:
- Add driver and DT schema for Zynq UltraScale+ MPSoCs devices with
Xilinx XDMA Soft IP (Thippeswamy Havalige)
Miscellaneous:
- Use FIELD_GET()/FIELD_PREP() to simplify and reduce use of _SHIFT
macros (Ilpo Järvinen, Bjorn Helgaas)
- Remove logic_outb(), _outw(), outl() duplicate declarations (John
Sanpe)
- Replace unnecessary UTF-8 in Kconfig help text because menuconfig
doesn't render it correctly (Liu Song)"

iommufd for 6.7
This branch has three new iommufd capabilities:
- Dirty tracking for DMA. AMD/ARM/Intel CPUs can now record if a DMA
writes to a page in the IOPTEs within the IO page table. This can be used
to generate a record of what memory is being dirtied by DMA activities
during a VM migration process. A VMM like qemu will combine the IOMMU
dirty bits with the CPU's dirty log to determine what memory to
transfer.
VFIO already has a DMA dirty tracking framework that requires PCI
devices to implement tracking HW internally. The iommufd version
provides an alternative that the VMM can select, if available. The two
are designed to have very similar APIs.
- Userspace controlled attributes for hardware page
tables (HWPT/iommu_domain). There are currently a few generic attributes
for HWPTs (support dirty tracking, and parent of a nest). This is an
entry point for the userspace iommu driver to control the HW in detail.
- Nested translation support for HWPTs. This is a 2D translation scheme
similar to the CPU where a DMA goes through a first stage to determine
an intermediate address which is then translated trough a second stage
to a physical address.
Like for CPU translation the first stage table would exist in VM
controlled memory and the second stage is in the kernel and matches the
VM's guest to physical map.
As every IOMMU has a unique set of parameter to describe the S1 IO page
table and its associated parameters the userspace IOMMU driver has to
marshal the information into the correct format.
This is 1/3 of the feature, it allows creating the nested translation
and binding it to VFIO devices, however the API to support IOTLB and
ATC invalidation of the stage 1 io page table, and forwarding of IO
faults are still in progress.
The series includes AMD and Intel support for dirty tracking. Intel
support for nested translation.
Along the way are a number of internal items:
- New iommu core items: ops->domain_alloc_user(), ops->set_dirty_tracking,
ops->read_and_clear_dirty(), IOMMU_DOMAIN_NESTED, and iommu_copy_struct_from_user
- UAF fix in iopt_area_split()
- Spelling fixes and some test suite improvement

VFIO updates for v6.7
- Add support for "chunk mode" in the mlx5-vfio-pci variant driver,
which allows both larger device image sizes for migration, beyond
the previous 4GB limit, and also read-ahead support for improved
migration performance. (Yishai Hadas)
- A new bus master control interface for the CDX bus driver where
there is no in-band mechanism to toggle device DMA as there is
through config space on PCI devices. (Nipun Gupta)
- Add explicit alignment directives to vfio data structures to
reduce the chance of breaking 32-bit userspace. In most cases
this is transparent and the remaining cases where data structures
are padded work within the existing rules for extending data
structures within vfio. (Stefan Hajnoczi)
- Resolve a bug in the cdx bus driver noted when compiled with clang
where missing parenthesis result in the wrong operation.
(Nathan Chancellor)
- Resolve errors reported by smatch for a function when dealing
with invalid inputs. (Alex Williamson)
- Add migration support to the mtty vfio/mdev sample driver for
testing and integration purposes, allowing CI of migration without
specific hardware requirements. Also resolve many of the short-
comings of this driver relative to implementation of the vfio
interrupt ioctl along the way. (Alex Williamson)

Merge tag 'io_uring-futex-2023-10-30' of git://git.kernel.dk/linux
Pull io_uring futex support from Jens Axboe:
"This adds support for using futexes through io_uring - first futex
wake and wait, and then the vectored variant of waiting, futex waitv.
For both wait/wake/waitv, we support the bitset variant, as the
'normal' variants can be easily implemented on top of that.
PI and requeue are not supported through io_uring, just the above
mentioned parts. This may change in the future, but in the spirit of
keeping this small (and based on what people have been asking for),
this is what we currently have.
Wake support is pretty straight forward, most of the thought has gone
into the wait side to avoid needing to offload wait operations to a
blocking context. Instead, we rely on the usual callbacks to retry and
post a completion event, when appropriate.
As far as I can recall, the first request for futex support with
io_uring came from Andres Freund, working on postgres. His aio rework
of postgres was one of the early adopters of io_uring, and futex
support was a natural extension for that. This is relevant from both a
usability point of view, as well as for effiency and performance. In
Andres's words, for the former:
Futex wait support in io_uring makes it a lot easier to avoid
deadlocks in concurrent programs that have their own buffer pool:
Obviously pages in the application buffer pool have to be locked
during IO. If the initiator of IO A needs to wait for a held lock
B, the holder of lock B might wait for the IO A to complete. The
ability to wait for a lock and IO completions at the same time
provides an efficient way to avoid such deadlocks
and in terms of effiency, even without unlocking the full potential
yet, Andres says:
Futex wake support in io_uring is useful because it allows for more
efficient directed wakeups. For some "locks" postgres has queues
implemented in userspace, with wakeup logic that cannot easily be
implemented with FUTEX_WAKE_BITSET on a single "futex word"
(imagine waiting for journal flushes to have completed up to a
certain point).
Thus a "lock release" sometimes need to wake up many processes in a
row. A quick-and-dirty conversion to doing these wakeups via
io_uring lead to a 3% throughput increase, with 12% fewer context
switches, albeit in a fairly extreme workload"

vhost-vdpa: introduce IOTLB_PERSIST backend feature bit
Userspace needs this feature flag to distinguish if vhost-vdpa iotlb in the kernel can be trusted to persist IOTLB mapping across vDPA reset. Without it, userspace has no way to tell apart if it's running on an older kernel, which could silently drop all iotlb mapping across vDPA reset, especially with broken parent driver implementation for the .reset driver op. The broken driver may incorrectly drop all mappings of its own as part of .reset, which inadvertently ends up with corrupted mapping state between vhost-vdpa userspace and the kernel. As a workaround, to make the mapping behaviour predictable across reset, userspace has to pro-actively remove all mappings before vDPA reset, and then restore all the mappings afterwards. This workaround is done unconditionally on top of all parent drivers today, due to the parent driver implementation issue and no means to differentiate. This workaround had been utilized in QEMU since day one when the corresponding vhost-vdpa userspace backend came to the world. There are 3 cases that backend may claim this feature bit on for: - parent device that has to work with platform IOMMU - parent device with on-chip IOMMU that has the expected .reset_map support in driver - parent device with vendor specific IOMMU implementation with persistent IOTLB mapping already that has to specifically declare this backend feature The reason why .reset_map is being one of the pre-condition for persistent iotlb is because without it, vhost-vdpa can't switch back iotlb to the initial state later on, especially for the on-chip IOMMU case which starts with identity mapping at device creation. virtio-vdpa requires on-chip IOMMU to perform 1:1 passthrough translation from PA to IOVA as-is to begin with, and .reset_map is the only means to turn back iotlb to the identity mapping mode after vhost-vdpa is gone. The difference in behavior did not matter as QEMU unmaps all the memory unregistering the memory listener at vhost_vdpa_dev_start( started = false), but the backend acknowledging this feature flag allows QEMU to make sure it is safe to skip this unmap & map in the case of vhost stop & start cycle. In that sense, this feature flag is actually a signal for userspace to know that the driver bug has been solved. Not offering it indicates that userspace cannot trust the kernel will retain the maps.

Userspace knows if the device has dedicated descriptor group or not by checking this feature bit. It's only exposed if the vdpa driver backend implements the .get_vq_desc_group() operation callback. Userspace trying to negotiate this feature when it or the dependent _F_IOTLB_ASID feature hasn't been exposed will result in an error.

KVM/arm64 updates for 6.7
- Generalized infrastructure for 'writable' ID registers, effectively
allowing userspace to opt-out of certain vCPU features for its guest
- Optimization for vSGI injection, opportunistically compressing MPIDR
to vCPU mapping into a table
- Improvements to KVM's PMU emulation, allowing userspace to select
the number of PMCs available to a VM
- Guest support for memory operation instructions (FEAT_MOPS)
- Cleanups to handling feature flags in KVM_ARM_VCPU_INIT, squashing
bugs and getting rid of useless code
- Changes to the way the SMCCC filter is constructed, avoiding wasted
memory allocations when not in use
- Load the stage-2 MMU context at vcpu_load() for VHE systems, reducing
the overhead of errata mitigations
- Miscellaneous kernel and selftest fixes
