Commit 97d5f2e9ee ("tools api fs: More thread safety for global
filesystem variables") introduces pthread_once, so the libpthread

selftests/x86: Update map_shadow_stack syscall nr
User visible changes:
- Added a way to easier filter with cpumasks:
# echo 'cpumask & CPUS{17-42}' > /sys/kernel/tracing/events/ipi_send_cpumask/filter
- Show actual size of ring buffer after modifying the ring buffer size via
buffer_size_kb. Currently it just returns what was written, but the actual
size rounds up to the sub buffer size. Show that real size instead.
Major changes:
- Added "eventfs". This is the code that handles the inodes and dentries of
tracefs/events directory. As there are thousands of events, and each event
has several inodes and dentries that currently exist even when tracing is
never used, they take up precious memory. Instead, eventfs will allocate
the inodes and dentries in a JIT way (similar to what procfs does). There
is now metadata that handles the events and subdirectories, and will create
the inodes and dentries when they are used.
Note, I also have patches that remove the subdirectory meta data, but will
wait till the next merge window before applying them. It's a little more
complex, and I want to make sure the dynamic code works properly before
adding more complexity, making it easier to revert if need be.
Minor changes:
- Optimization to user event list traversal.
- Remove intermediate permission of tracefs files (note the intermediate
permission removes all access to the files so it is not a security concern,
but just a clean up.)
- Add the complex fix to FORTIFY_SOURCE to the kernel stack event logic.
- Other minor clean ups.

* Unbound workqueues now support more flexible affinity scopes. The default
behavior is to soft-affine according to last level cache boundaries. A
work item queued from a given LLC is executed by a worker running on the
same LLC but the worker may be moved across cache boundaries as the
scheduler sees fit. On machines which multiple L3 caches, which are
becoming more popular along with chiplet designs, this improves cache
locality while not harming work conservation too much.
Unbound workqueues are now also a lot more flexible in terms of execution
affinity. Differeing levels of affinity scopes are supported and both the
default and per-workqueue affinity settings can be modified dynamically.
This should help working around amny of sub-optimal behaviors observed
recently with asymmetric ARM CPUs.
This involved signficant restructuring of workqueue code. Nothing was
reported yet but there's some risk of subtle regressions. Should keep an
eye out.
* Rescuer workers now has more identifiable comms.
* workqueue.unbound_cpus added so that CPUs which can be used by workqueue

* Now that all the in-tree users have been flushed out, trigger warning if

Shadow stack's selftest utilizes the map_shadow_stack syscall. The
syscall is new with the feature, but the selftests cannot automatically
find the headers for the kernel source tree they are located in. This
resulted in the shadow stack test failing to build until the brand new
headers were installed.
To avoid this, a copy of the new uapi defines needed by the test were
included in the selftest (see link for discussion). When shadow stack was
merged the syscall number was changed, but the copy in the selftest was
not updated.
So update the copy of the syscall number define used when the required
headers are not installed, to have the final syscall number from the
merge.

Pull x86 shadow stack support from Dave Hansen:
"This is the long awaited x86 shadow stack support, part of Intel's
Control-flow Enforcement Technology (CET).
CET consists of two related security features: shadow stacks and
indirect branch tracking. This series implements just the shadow stack
part of this feature, and just for userspace.
The main use case for shadow stack is providing protection against
return oriented programming attacks. It works by maintaining a
secondary (shadow) stack using a special memory type that has
protections against modification. When executing a CALL instruction,
the processor pushes the return address to both the normal stack and
to the special permission shadow stack. Upon RET, the processor pops
the shadow stack copy and compares it to the normal stack copy.
For more information, refer to the links below for the earlier
versions of this patch set"

Charlie Jenkins <charlie@rivosinc.com> says:
Make sv48 the default address space for mmap as some applications
currently depend on this assumption. Users can now select a
desired address space using a non-zero hint address to mmap. Previously,
requesting the default address space from mmap by passing zero as the hint
address would result in using the largest address space possible. Some
applications depend on empty bits in the virtual address space, like Go and
Java, so this patch provides more flexibility for application developers.

This includes a shared branch with VFIO:
- Enhance VFIO_DEVICE_GET_PCI_HOT_RESET_INFO so it can work with iommufd
FDs, not just group FDs. This removes the last place in the uAPI that
required the group fd.
- Give VFIO a new device node /dev/vfio/devices/vfioX (the so called cdev
node) which is very similar to the FD from VFIO_GROUP_GET_DEVICE_FD.
The cdev is associated with the struct device that the VFIO driver is
bound to and shows up in sysfs in the normal way.
- Add a cdev IOCTL VFIO_DEVICE_BIND_IOMMUFD which allows a newly opened
/dev/vfio/devices/vfioX to be associated with an IOMMUFD, this replaces
the VFIO_GROUP_SET_CONTAINER flow.
- Add cdev IOCTLs VFIO_DEVICE_[AT|DE]TACH_IOMMUFD_PT to allow the IOMMU
translation the vfio_device is associated with to be changed. This is a
significant new feature for VFIO as previously each vfio_device was
fixed to a single translation.
The translation is under the control of iommufd, so it can be any of
the different translation modes that iommufd is learning to create.
At this point VFIO has compilation options to remove the legacy interfaces
and in modern mode it behaves like a normal driver subsystem. The
/dev/vfio/iommu and /dev/vfio/groupX nodes are not present and each
vfio_device only has a /dev/vfio/devices/vfioX cdev node that represents
the device.
On top of this is built some of the new iommufd functionality:
- IOMMU_HWPT_ALLOC allows userspace to directly create the low level
IO Page table objects and affiliate them with IOAS objects that hold
the translation mapping. This is the basic functionality for the
normal IOMMU_DOMAIN_PAGING domains.
- VFIO_DEVICE_ATTACH_IOMMUFD_PT can be used to replace the current
translation. This is wired up to through all the layers down to the
driver so the driver has the ability to implement a hitless
replacement. This is necessary to fully support guest behaviors when
emulating HW (eg guest atomic change of translation)
- IOMMU_GET_HW_INFO returns information about the IOMMU driver HW that
owns a VFIO device. This includes support for the Intel iommu, and
patches have been posted for all the other server IOMMU.
Along the way are a number of internal items:
- New iommufd kapis iommufd_ctx_has_group(), iommufd_device_to_ictx(),
iommufd_device_to_id(), iommufd_access_detach(), iommufd_ctx_from_fd(),
iommufd_device_replace()
- iommufd now internally tracks iommu_groups as it needs some per-group
data
- Reorganize how the internal hwpt allocation flows to have more robust
locking
- Improve the access interfaces to support detach and replace of an IOAS
from an access
- New selftests and a rework of how the selftests creates a mock iommu
driver to be more like a real iommu driver

We've received a fairly wide range of changes at this time, including
for ALSA and ASoC core, but all of them are rather small changes.
Here are some highlights:
ALSA / ASoC Core:
- Fixes of inconsistent locking around control API helpers
- A few new control API functions and cleanups
- Workarounds for potential UAFs by delayed kobj releases
- Unified PCM copy ops with iov_iter
- Continued efforts for ASoC API cleanups
ASoC:
- An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in
some IIO changes
- Create a library function for intlog10() and use it in the NAU8825
driver
- Convert drivers to use the more modern maple tree register cache
- Lots of work on the SOF framework, AMD and Intel drivers, including a
lot of cleanup and new device support
- Standardization of the presentation of jacks from drivers
- Provision of some generic sound card DT properties
- Support for AMD Van Gogh, AMD machines with MAX98388 and NAU8821,
AWInic AW88261, Cirrus Logic CS35L36 and CS42L43, various Intel
platforms including AVS machines with ES8336 and RT5663, Mediatek
MT7986, NXP i.MX93, RealTek RT1017 and StarFive JH7110
Others:
- New test coverage including ASoC and topology tests in KUnit;
this also involves enabling UML builds of ALSA since that's the
default KUnit test environment which pulls in the addition of some
stubs to the driver
- More enhancement of pcmtest driver
- A few fixes / enhancements of MIDI 2.0 UMP core
- Using PCI definitions in allover HD-audio code
- Support for Cirrus CS35L56 and TI TAS2781 HD-audio sub-codecs
- CS35L41 HD-audio sub-codec improvements
- Continued emu10k1 improvements

Pull x86 apic updates from Dave Hansen:
"This includes a very thorough rework of the 'struct apic' handlers.
Quite a variety of them popped up over the years, especially in the
32-bit days when odd apics were much more in vogue.
The end result speaks for itself, which is a removal of a ton of code
and static calls to replace indirect calls.
If there's any breakage here, it's likely to be around the 32-bit
museum pieces that get light to no testing these days.
Summary:
- Rework apic callbacks, getting rid of unnecessary ones and
coalescing lots of silly duplicates.
- Use static_calls() instead of indirect calls for apic->foo()
- Tons of cleanups an crap removal along the way"

- Remove the io_uring userspace code. These were added initially as
copies from liburing, but all of them have since bitrotted and are
way out of date at this point. Rather than attempt to keep them in

- Teach verifier actual bounds of bpf_get_smp_processor_id()
and fix perf+libbpf issue related to custom section handling.
- Introduce bpf map element count and enable it for all program types.
- Add a BPF hook in sys_socket() to change the protocol ID
from IPPROTO_TCP to IPPROTO_MPTCP to cover migration for legacy.
- Introduce bpf_me_mcache_free_rcu() and fix OOM under stress.
- Add uprobe support for the bpf_get_func_ip helper.
- Check skb ownership against full socket.
- Support for up to 12 arguments in BPF trampoline.
- Extend link_info for kprobe_multi and perf_event links.
Netfilter
---------
- Speed-up process exit by aborting ruleset validation if a
fatal signal is pending.

Driver API
----------
- Page pool optimizations, to improve data locality and cache usage.
- Introduce ndo_hwtstamp_get() and ndo_hwtstamp_set() to avoid the need
for raw ioctl() handling in drivers.
- Simplify genetlink dump operations (doit/dumpit) providing them
the common information already populated in struct genl_info.
- Extend and use the yaml devlink specs to [re]generate the split ops.
- Introduce devlink selective dumps, to allow SF filtering SF based on
handle and other attributes.
- Add yaml netlink spec for netlink-raw families, allow route, link and
address related queries via the ynl tool.

This is a much quieter release than the past few, there's one small API
addition that I noticed a user for in ALSA and a bunch of cleanups:
- Provide an interface for determining if a register is present in the
cache and add a user of it in ALSA.
- Full support for dynamic allocations, following the temporary bodges
that were done as fixes in the previous release.
- Remove the unused and questionably working 64 bit support.

Pull power management updates from Rafael Wysocki:
"These rework cpuidle governors to call tick_nohz_get_sleep_length()
less often and fix one of them, rework hibernation to avoid storing
pages filled with zeros in hibernation images, switch over some
cpufreq drivers to use void remove callbacks, fix and clean up
multiple cpufreq drivers, fix the devfreq core, update the cpupower
utility and make other assorted improvements.

Pull procfs fixes from Christian Brauner:
"Mode changes to files under /proc/<pid>/ aren't supported ever since
commit 6d76fa58b0 ("Don't allow chmod() on the /proc/<pid>/ files").
Due to an oversight in commit 1b3044e39a ("procfs: fix pthread
cross-thread naming if !PR_DUMPABLE") in switching from REG to NOD,
mode changes on /proc/thread-self/comm were accidently allowed.
Similar, mode changes for all files beneath /proc/<pid>/net/ are
blocked but mode changes on /proc/<pid>/net itself were accidently
allowed.
Both issues come down to not using the generic proc_setattr() helper
which blocks all mode changes. This is rectified with this pull
request.
This also removes a strange nolibc test that abused /proc/<pid>/net
for testing mode changes. Using procfs for this test never made a lot
of sense given procfs has special semantics for almost everything
anway.
Both changes are minor user-visible changes. It is however very
unlikely that mode changes on proc/<pid>/net and
/proc/thread-self/comm are something that userspace relies on"

Merge tag 'v6.6-vfs.fchmodat2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull fchmodat2 system call from Christian Brauner:
"This adds the fchmodat2() system call. It is a revised version of the
fchmodat() system call, adding a missing flag argument. Support for
both AT_SYMLINK_NOFOLLOW and AT_EMPTY_PATH are included.
Adding this system call revision has been a longstanding request but
so far has always fallen through the cracks. While the kernel
implementation of fchmodat() does not have a flag argument the libc
provided POSIX-compliant fchmodat(3) version does. Both glibc and musl
have to implement a workaround in order to support AT_SYMLINK_NOFOLLOW
(see [1] and [2]).
The workaround is brittle because it relies not just on O_PATH and
O_NOFOLLOW semantics and procfs magic links but also on our rather
inconsistent symlink semantics.
This gives userspace a proper fchmodat2() system call that libcs can
use to properly implement fchmodat(3) and allows them to get rid of
their hacks. In this case it will immediately benefit them as the
current workaround is already defunct because of aformentioned
inconsistencies.
In addition to AT_SYMLINK_NOFOLLOW, give userspace the ability to use
AT_EMPTY_PATH with fchmodat2(). This is already possible with
fchownat() so there's no reason to not also support it for
fchmodat2().
The implementation is simple and comes with selftests. Implementation
of the system call and wiring up the system call are done as separate
patches even though they could arguably be one patch. But in case
there are merge conflicts from other system call additions it can be
beneficial to have separate patches"

If failed to set link1_1 to netns client, we should delete link1_1 in the
cleanup path. But if set link1_1 to netns client successfully, delete
link1_1 will report warning. So it will be safer creating directly the
devices in the target namespaces.

We use a tempfile for code generation, to avoid wiping the target
file out if the code generator crashes. File contents are copied
from tempfile to actual destination at the end of main().
uAPI generation is relatively simple so when generating the uAPI
header we return from main() early, and never reach the "copy code
over" stage. Since commit under Fixes uAPI headers are not updated
by ynl-gen.
Move the copy/commit of the code into CodeWriter, to make it
easier to call at any point in time. Hook it into the destructor
to make sure we don't miss calling it.
