The commit 97c79a38cd ("perf core: Per event callchain limit")
introduced a per-event term to allow finer tuning of the depth of
callchains to save space.
It should be applied to the branch stack as well. For example, autoFDO
collections require maximum LBR entries. In the meantime, other
system-wide LBR users may only be interested in the latest a few number
of LBRs. A per-event LBR depth would save the perf output buffer.
The patch simply drops the uninterested branches, but HW still collects
the maximum branches. There may be a model-specific optimization that
can reduce the HW depth for some cases to reduce the overhead further.
But it isn't included in the patch set. Because it's not useful for all
cases. For example, ARCH LBR can utilize the PEBS and XSAVE to collect
LBRs. The depth should have less impact on the collecting overhead.
The model-specific optimization may be implemented later separately.

Introduce BPF instructions with load-acquire and store-release
semantics, as discussed in [1]. Define 2 new flags:
#define BPF_LOAD_ACQ 0x100
#define BPF_STORE_REL 0x110
A "load-acquire" is a BPF_STX | BPF_ATOMIC instruction with the 'imm'
field set to BPF_LOAD_ACQ (0x100).
Similarly, a "store-release" is a BPF_STX | BPF_ATOMIC instruction with
the 'imm' field set to BPF_STORE_REL (0x110).
Unlike existing atomic read-modify-write operations that only support
BPF_W (32-bit) and BPF_DW (64-bit) size modifiers, load-acquires and
store-releases also support BPF_B (8-bit) and BPF_H (16-bit). As an
exception, however, 64-bit load-acquires/store-releases are not
supported on 32-bit architectures (to fix a build error reported by the
kernel test robot).
An 8- or 16-bit load-acquire zero-extends the value before writing it to
a 32-bit register, just like ARM64 instruction LDARH and friends.
Similar to existing atomic read-modify-write operations, misaligned
load-acquires/store-releases are not allowed (even if
BPF_F_ANY_ALIGNMENT is set).
As an example, consider the following 64-bit load-acquire BPF
instruction (assuming little-endian):
db 10 00 00 00 01 00 00 r0 = load_acquire((u64 *)(r1 + 0x0))
opcode (0xdb): BPF_ATOMIC | BPF_DW | BPF_STX
imm (0x00000100): BPF_LOAD_ACQ
Similarly, a 16-bit BPF store-release:
cb 21 00 00 10 01 00 00 store_release((u16 *)(r1 + 0x0), w2)
opcode (0xcb): BPF_ATOMIC | BPF_H | BPF_STX
imm (0x00000110): BPF_STORE_REL
In arch/{arm64,s390,x86}/net/bpf_jit_comp.c, have
bpf_jit_supports_insn(..., /*in_arena=*/true) return false for the new
instructions, until the corresponding JIT compiler supports them in
arena.

Currently for bpf progs in a cgroup hierarchy, the effective prog array
is computed from bottom cgroup to upper cgroups (post-ordering). For
example, the following cgroup hierarchy
root cgroup: p1, p2
subcgroup: p3, p4
have BPF_F_ALLOW_MULTI for both cgroup levels.
The effective cgroup array ordering looks like
p3 p4 p1 p2
and at run time, progs will execute based on that order.
But in some cases, it is desirable to have root prog executes earlier than
children progs (pre-ordering). For example,
- prog p1 intends to collect original pkt dest addresses.
- prog p3 will modify original pkt dest addresses to a proxy address for
security reason.
The end result is that prog p1 gets proxy address which is not what it
wants. Putting p1 to every child cgroup is not desirable either as it
will duplicate itself in many child cgroups. And this is exactly a use case
we are encountering in Meta.
To fix this issue, let us introduce a flag BPF_F_PREORDER. If the flag
is specified at attachment time, the prog has higher priority and the
ordering with that flag will be from top to bottom (pre-ordering).
For example, in the above example,
root cgroup: p1, p2
subcgroup: p3, p4
Let us say p2 and p4 are marked with BPF_F_PREORDER. The final
effective array ordering will be
p2 p4 p3 p1

IIO: New device support, features and cleanup for the 6.15 cycle.
The usual mixture of new drivers, support in existing drivers for new
devices, a range of features and general subsystem cleanup.
Two merges of immutable branches in here:

Cleanup and minor bug fixes
===========================
Tree wide:
- Stop using iio_device_claim_direct_scoped() and introduce sparse friendly
iio_device_claim/release_direct()
The conditional scoped cleanup has proved hard to deal with, requiring
workarounds for various compiler issues and in is rather non-intuitive
so abandon that experiment. One of the attractions of that approach was
that it made it much harder to have unbalanced claim/release bugs so
instead introduce a conditional-lock style boolean returning new pair
of functions. These are inline in the header and have __acquire and
__release calls allowing sparse to detect lack of balance. There are
occasional false positives but so far those have reflected complex code
paths that benefited from cleanup anyway.
The first set of driver conversions are in this pull request, more to
follow next cycle. Various related cleanup in drivers.
Removal of the _scoped code is completed and the definition removed.
- Use of str_enable_disable() and similar helpers.
- Don't set regmap cache to REGCACHE_NONE as that's the default anyway.
- Change some caches from RBTREE to MAPLE reflecting best practice.
- Use the new gpiod_multi_set_value_cansleep()
- Make sure to grab direct mode for some calibrations paths.
- Avoid using memcmp on structures when checking for matching channel configs.
Instead just match field by field.
dt-bindings:
- Fix up indentation inconsistencies.
gts-helper:
- Simplify building of available scale table.
adi,ad-sigma-delta
- Make sure to disable channel after calibration done.
- Add error handling in configuring channel during calibration.
adi,ad2s1201
- use a bitmap_write() rather than directly accessing underlying storage.
adi,ad3552r-hs
- Fix a wrong error message.
- Make sure to use instruction mode for configuration.
adi,ad4695
- Add a conversion to ensure exit from conversion mode.
- Use custom regmap to handle required sclk rate change.

Checkpoint/Restore in Userspace (CRIU) requires to reconstruct posix timers
with the same timer ID on restore. It uses sys_timer_create() and relies on
the monotonic increasing timer ID provided by this syscall. It creates and
deletes timers until the desired ID is reached. This is can loop for a long
time, when the checkpointed process had a very sparse timer ID range.
It has been debated to implement a new syscall to allow the creation of
timers with a given timer ID, but that's tideous due to the 32/64bit compat
issues of sigevent_t and of dubious value.
The restore mechanism of CRIU creates the timers in a state where all
threads of the restored process are held on a barrier and cannot issue
syscalls. That means the restorer task has exclusive control.
This allows to address this issue with a prctl() so that the restorer
thread can do:
if (prctl(PR_TIMER_CREATE_RESTORE_IDS, PR_TIMER_CREATE_RESTORE_IDS_ON))
goto linear_mode;
create_timers_with_explicit_ids();
prctl(PR_TIMER_CREATE_RESTORE_IDS, PR_TIMER_CREATE_RESTORE_IDS_OFF);
This is backwards compatible because the prctl() fails on older kernels and
CRIU can fall back to the linear timer ID mechanism. CRIU versions which do
not know about the prctl() just work as before.
Implement the prctl() and modify timer_create() so that it copies the
requested timer ID from userspace by utilizing the existing timer_t
pointer, which is used to copy out the allocated timer ID on success.
If the prctl() is disabled, which it is by default, timer_create() works as
before and does not try to read from the userspace pointer.
There is no problem when a broken or rogue user space application enables
the prctl(). If the user space pointer does not contain a valid ID, then
timer_create() fails. If the data is not initialized, but constains a
random valid ID, timer_create() will create that random timer ID or fail if
the ID is already given out.
As CRIU must use the raw syscall to avoid manipulating the internal state
of the restored process, this has no library dependencies and can be
adopted by CRIU right away.
Recreating two timers with IDs 1000000 and 2000000 takes 1.5 seconds with
the create/delete method. With the prctl() it takes 3 microseconds.

The legacy rpc.nfsd tool will set the nlm_grace_period if the NFSv4
grace period is set. nfsdctl is missing this functionality, so add a new
netlink control interface for lockd that it can use. For now, it only
allows setting the grace period, and the tcp and udp listener ports.
lockd currently uses module parameters and sysctls for configuration, so
all of its settings are global. With this change, lockd now tracks these
values on a per-net-ns basis. It will only fall back to using the global
values if any of them are 0.
Finally, as a backward compatibility measure, if updating the nlm
settings in the init_net namespace, also update the legacy global
values to match.

Since commit 05c1280a2b ("netdev_features: convert NETIF_F_NETNS_LOCAL to
dev->netns_local"), there is no way to see if the netns_immutable property
s set on a device. Let's add a netlink attribute to advertise it.

The in-tree ublk driver doesn't need DMA alignment limit because there
is one data copy between request pages and the userspace buffer.
However, ublk is going to support zero copy, then DMA alignment limit
is required, because same IO buffer is forwarded to backend which may
have specific buffer DMA alignment limit, so the limit has to be exposed
from the frontend driver to client application.

In preparation for memtostr*() checking that its source is marked as
nonstring, annotate the device strings accordingly using the new UAPI
alias for the "nonstring" attribute.

In order to annotate byte arrays in UAPI that are not C strings (i.e.
they may not be NUL terminated), the "nonstring" attribute is needed.
However, we can't expose this to userspace as it is compiler version
specific.
