Saeed Mahameed says:
====================
aux-sysfs-irqs
Shay Says:
==========
Introduce auxiliary bus IRQs sysfs
Today, PCI PFs and VFs, which are anchored on the PCI bus, display their
IRQ information in the <pci_device>/msi_irqs/<irq_num> sysfs files. PCI
subfunctions (SFs) are similar to PFs and VFs and these SFs are anchored
on the auxiliary bus. However, these PCI SFs lack such IRQ information
on the auxiliary bus, leaving users without visibility into which IRQs
are used by the SFs. This absence makes it impossible to debug
situations and to understand the source of interrupts/SFs for
performance tuning and debug.
Additionally, the SFs are multifunctional devices supporting RDMA,
network devices, clocks, and more, similar to their peer PCI PFs and
VFs. Therefore, it is desirable to have SFs' IRQ information available
at the bus/device level.
To overcome the above limitations, this short series extends the
auxiliary bus to display IRQ information in sysfs, similar to that of
PFs and VFs.
It adds an 'irqs' directory under the auxiliary device and includes an
<irq_num> sysfs file within it.
For example:
$ ls /sys/bus/auxiliary/devices/mlx5_core.sf.1/irqs/
50 51 52 53 54 55 56 57 58
Patch summary:
patch-1 adds auxiliary bus to support irqs used by auxiliary device
patch-2 mlx5 driver using exposing irqs for PCI SF devices via auxiliary
bus

Pull pidfs updates from Christian Brauner:
"This contains work to make it possible to derive namespace file
descriptors from pidfd file descriptors.
Right now it is already possible to use a pidfd with setns() to
atomically change multiple namespaces at the same time. In other
words, it is possible to switch to the namespace context of a process
using a pidfd. There is no need to first open namespace file
descriptors via procfs.
The work included here is an extension of these abilities by allowing
to open namespace file descriptors using a pidfd. This means it is now
possible to interact with namespaces without ever touching procfs.
To this end a new set of ioctls() on pidfds is introduced covering all
supported namespace types"

Pull namespace-fs updates from Christian Brauner:
"This adds ioctls allowing to translate PIDs between PID namespaces.
The motivating use-case comes from LXCFS which is a tiny fuse
filesystem used to virtualize various aspects of procfs. LXCFS is run
on the host. The files and directories it creates can be bind-mounted
by e.g. a container at startup and mounted over the various procfs
files the container wishes to have virtualized.
When e.g. a read request for uptime is received, LXCFS will receive
the pid of the reader. In order to virtualize the corresponding read,
LXCFS needs to know the pid of the init process of the reader's pid
namespace.
In order to do this, LXCFS first needs to fork() two helper processes.
The first helper process setns() to the readers pid namespace. The
second helper process is needed to create a process that is a proper
member of the pid namespace.
The second helper process then creates a ucred message with ucred.pid
set to 1 and sends it back to LXCFS. The kernel will translate the
ucred.pid field to the corresponding pid number in LXCFS's pid
namespace. This way LXCFS can learn the init pid number of the
reader's pid namespace and can go on to virtualize.
Since these two forks() are costly LXCFS maintains an init pid cache
that caches a given pid for a fixed amount of time. The cache is
pruned during new read requests. However, even with the cache the hit
of the two forks() is singificant when a very large number of
containers are running.
So this adds a simple set of ioctls that let's a caller translate PIDs
from and into a given PID namespace. This significantly improves
performance with a very simple change.
To protect against races pidfds can be used to check whether the
process is still valid"

Pull vfs mount query updates from Christian Brauner:
"This contains work to extend the abilities of listmount() and
statmount() and various fixes and cleanups.
Features:
- Allow iterating through mounts via listmount() from newest to
oldest. This makes it possible for mount(8) to keep iterating the
mount table in reverse order so it gets newest mounts first.
- Relax permissions on listmount() and statmount().
It's not necessary to have capabilities in the initial namespace:
it is sufficient to have capabilities in the owning namespace of
the mount namespace we're located in to list unreachable mounts in
that namespace.
- Extend both listmount() and statmount() to list and stat mounts in
foreign mount namespaces.
Currently the only way to iterate over mount entries in mount
namespaces that aren't in the caller's mount namespace is by
crawling through /proc in order to find /proc/<pid>/mountinfo for
the relevant mount namespace.
This is both very clumsy and hugely inefficient. So extend struct
mnt_id_req with a new member that allows to specify the mount
namespace id of the mount namespace we want to look at.
Luckily internally we already have most of the infrastructure for
this so we just need to expose it to userspace. Give userspace a
way to retrieve the id of a mount namespace via statmount() and
through a new nsfs ioctl() on mount namespace file descriptor.
This comes with appropriate selftests.
- Expose mount options through statmount().
Currently if userspace wants to get mount options for a mount and
with statmount(), they still have to open /proc/<pid>/mountinfo to
parse mount options. Simply the information through statmount()
directly.
Afterwards it's possible to only rely on statmount() and
listmount() to retrieve all and more information than
/proc/<pid>/mountinfo provides.
This comes with appropriate selftests.
Fixes:
- Avoid copying to userspace under the namespace semaphore in
listmount.
Cleanups:
- Simplify the error handling in listmount by relying on our newly
added cleanup infrastructure.
- Refuse invalid mount ids early for both listmount and statmount"

Pull vfs inode / dentry updates from Christian Brauner:
"This contains smaller performance improvements to inodes and dentries:
inode:
- Add rcu based inode lookup variants.
They avoid one inode hash lock acquire in the common case thereby
significantly reducing contention. We already support RCU-based
operations but didn't take advantage of them during inode
insertion.
Callers of iget_locked() get the improvement without any code
changes. Callers that need a custom callback can switch to
iget5_locked_rcu() as e.g., did btrfs.
With 20 threads each walking a dedicated 1000 dirs * 1000 files
directory tree to stat(2) on a 32 core + 24GB ram vm:
before: 3.54s user 892.30s system 1966% cpu 45.549 total
after: 3.28s user 738.66s system 1955% cpu 37.932 total (-16.7%)
Long-term we should pick up the effort to introduce more
fine-grained locking and possibly improve on the currently used
hash implementation.
- Start zeroing i_state in inode_init_always() instead of doing it in
individual filesystems.
This allows us to remove an unneeded lock acquire in new_inode()
and not burden individual filesystems with this.
dcache:
- Move d_lockref out of the area used by RCU lookup to avoid
cacheline ping poing because the embedded name is sharing a
cacheline with d_lockref.
- Fix dentry size on 32bit with CONFIG_SMP=y so it does actually end
up with 128 bytes in total"

options is a sensitive operation in the face of idmappings.

verify that the specified uid and gid can be represented in the
owning namespace of the filesystem.

Pull misc vfs updates from Christian Brauner:
"Features:
- Support passing NULL along AT_EMPTY_PATH for statx().
NULL paths with any flag value other than AT_EMPTY_PATH go the
usual route and end up with -EFAULT to retain compatibility (Rust
is abusing calls of the sort to detect availability of statx)
This avoids path lookup code, lockref management, memory allocation
and in case of NULL path userspace memory access (which can be
quite expensive with SMAP on x86_64)
- Don't block i_writecount during exec. Remove the
deny_write_access() mechanism for executables
- Relax open_by_handle_at() permissions in specific cases where we
can prove that the caller had sufficient privileges to open a file
- Switch timespec64 fields in struct inode to discrete integers
freeing up 4 bytes
Fixes:
- Fix false positive circular locking warning in hfsplus
- Initialize hfs_inode_info after hfs_alloc_inode() in hfs
- Avoid accidental overflows in vfs_fallocate()
- Don't interrupt fallocate with EINTR in tmpfs to avoid constantly
restarting shmem_fallocate()
- Add missing quote in comment in fs/readdir
Cleanups:
- Don't assign and test in an if statement in mqueue. Move the
assignment out of the if statement
- Reflow the logic in may_create_in_sticky()
- Remove the usage of the deprecated ida_simple_xx() API from procfs
- Reject FSCONFIG_CMD_CREATE_EXCL requets that depend on the new

- Rename variables in copy_tree() to make it easier to understand
- Replace WARN(down_read_trylock, ...) abuse with proper asserts in

This patch changes how TCA_FLOWER_KEY_ENC_FLAGS is used, so that
it is used with TCA_FLOWER_KEY_FLAGS_* flags, in the same way as
TCA_FLOWER_KEY_FLAGS is currently used.
Where TCA_FLOWER_KEY_FLAGS uses {key,mask}->control.flags, then
TCA_FLOWER_KEY_ENC_FLAGS now uses {key,mask}->enc_control.flags,
therefore {key,mask}->enc_flags is now unused.
As the generic fl_set_key_flags/fl_dump_key_flags() is used with
encap set to true, then fl_{set,dump}_key_enc_flags() is removed.
This breaks unreleased userspace API (net-next since 2024-06-04).

Define new TCA_FLOWER_KEY_FLAGS_* flags for use in struct
flow_dissector_key_control, covering the same flags as
currently exposed through TCA_FLOWER_KEY_ENC_FLAGS.
Put the new flags under FLOW_DIS_F_*. The idea is that we can
later, move the existing flags under FLOW_DIS_F_* as well.
The ynl flag names have been taken from the RFC iproute2 patch.

Redefine the flower control flags as an enum, so they are
included in BTF info.
Make the kernel-side enum a more explicit superset of
TCA_FLOWER_KEY_FLAGS_*, new flags still need to be added to
both enums, but at least the bit position only has to be
defined once.
FLOW_DIS_ENCAPSULATION is never set for mask, so it can't be
exposed to userspace in an unsupported flags mask error message,
so it will be placed one bit position above the last uAPI flag.

Merge runtime constants infrastructure with implementations for x86 and
arm64.
This is one of four branches that came out of me looking at profiles of
my kernel build filesystem load on my 128-core Altra arm64 system, where
pathname walking and the user copies (particularly strncpy_from_user()
for fetching the pathname from user space) is very hot.
This is a very specialized "instruction alternatives" model where the
dentry hash pointer and hash count will be constants for the lifetime of
the kernel, but the allocation are not static but done early during the
kernel boot. In order to avoid the pointer load and dynamic shift, we
just rewrite the constants in the instructions in place.
We can't use the "generic" alternative instructions infrastructure,
because different architectures do it very differently, and it's
actually simpler to just have very specific helpers, with a fallback to
the generic ("old") model of just using variables for architectures that
do not implement the runtime constant patching infrastructure.

* runtime-constants:

In prevision to add new UAPI for hwtstamp we will be limited to the struct
ethtool_ts_info that is currently passed in fixed binary format through the
ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code
already started operating on an extensible kernel variant of that
structure, similar in concept to struct kernel_hwtstamp_config vs struct
hwtstamp_config.
Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here
we introduce the kernel-only structure in include/linux/ethtool.h.
The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

Change the API to select MAC default time stamping instead of the PHY.
Indeed the PHY is closer to the wire therefore theoretically it has less
delay than the MAC timestamping but the reality is different. Due to lower
time stamping clock frequency, latency in the MDIO bus and no PHC hardware
synchronization between different PHY, the PHY PTP is often less precise
than the MAC. The exception is for PHY designed specially for PTP case but
these devices are not very widespread. For not breaking the compatibility
default_timestamp flag has been introduced in phy_device that is set by
the phy driver to know we are using the old API behavior.

ASoC: Updates for for v6.11
There are a lot of changes in here, though the big bulk of things is
cleanups and simplifications of various kinds which are internally
rather than externally visible. A good chunk of those are DT schema
conversions, but there's also a lot of changes in the code.
Highlights:
- Syncing of features between simple-audio-card and the two
audio-graph cards so there is no reason to stick with an older
driver.
- Support for specifying the order of operations for components within
cards to allow quirking for unusual systems.
- New support for Asahi Kasei AK4619, Cirrus Logic CS530x, Everest
Semiconductors ES8311, NXP i.MX95 and LPC32xx, Qualcomm LPASS v2.5
and WCD937x, Realtek RT1318 and RT1320 and Texas Instruments PCM5242.

The 'dsa_tag_8021q_bridge_join' could be used as a generic implementation

Relying on position in the enum makes it subtly harder when doing merge
resolutions or backporting as it is easy to grab a patch and not notice it
is a uAPI change with a differently ordered enum. This may become a bigger
problem in next cycles when iommu_hwpt_invalidate_data_type and other
per-driver enums have patches flowing through different trees.
So lets start including constants for all the uAPI enums to make this
safer.
No functional change.

Fix thermal zone names for consistency with the other SoCs:
- GPU0 must be used as the first GPU item.
- SOCx deal with audio DSP, video, and infra subsystems.
The naming must be fixed "atomically" so compilation does not break.
As a result, the change is made in the dt-bindings and in the LVTS
driver within a single commit, despite the checkpatch warning.
The definitions can be safely modified here because they are used only
in the LVTS driver, which is modified accordingly, and have not yet
