Accidentally spotted while trying to understand what else needs
to be renamed to netif_ prefix. Most of the calls to dev_set_promiscuity
are adjacent to dev_set_allmulti or dev_disable_lro so it should
be safe to add the lock. Note that new netif_set_promiscuity is
currently unused, the locked paths call __dev_set_promiscuity directly.

When compressed data deduplication is enabled, multiple logical extents
may reference the same compressed physical cluster.
The previous commit 94c43de735 ("erofs: fix wrong primary bvec
selection on deduplicated extents") already avoids using shortened
bvecs. However, in such cases, the extra temporary buffers also
need to be preserved for later use in z_erofs_fill_other_copies() to
to prevent data corruption.
IOWs, extra temporary buffers have to be retained not only due to
varying start relative offsets (`pageofs_out`, as indicated by
`pcl->multibases`) but also because of shortened bvecs.
android.hardware.graphics.composer@2.1.so : 270696 bytes
0: 0.. 204185 | 204185 : 628019200.. 628084736 | 65536

366: 54309344..54514557 | 205213 : 544129024.. 544194560 | 65536
...
Both 204185 and 54095257 have the same start relative offset of 3481,
but the logical page 55 of `android.hardware.graphics.composer@2.1.so`
ranges from 225280 to 229632, forming a shortened bvec [225280, 225536)
that cannot be used for decompressing the range from 54095257 to
54309344 of `com.android.vndk.v28.apex`.
Since `pcl->multibases` is already meaningless, just mark `be->keepxcpy`
on demand for simplicity.
Again, this issue can only lead to data corruption if `-Ededupe` is on.

__qdisc_destroy() calls into various qdiscs .destroy() op, which in turn
can call .ndo_setup_tc(), which requires the netdev instance lock.
This commit extends the critical section in
unregister_netdevice_many_notify() to cover dev_shutdown() (and
dev_tcx_uninstall() as a side-effect) and acquires the netdev instance
lock in __dev_change_net_namespace() for the other dev_shutdown() call.
This should now guarantee that for all qdisc ops, the netdev instance
lock is held during .ndo_setup_tc().

Use Device Serial Number instead of PCI bus/device/function for
the index of struct ice_adapter.
Functions on the same physical device should point to the very same
ice_adapter instance, but with two PFs, when at least one of them is
PCI-e passed-through to a VM, it is no longer the case - PFs will get
seemingly random PCI BDF values, and thus indices, what finally leds to
each of them being on their own instance of ice_adapter. That causes them
to don't attempt any synchronization of the PTP HW clock usage, or any
other future resources.
DSN works nicely in place of the index, as it is "immutable" in terms of
virtualization.
Fixes: 0e2bddf9e5 ("ice: add ice_adapter for shared data across PFs on the same NIC")

devlink: sanitize variable typed attributes
This is continuation based on first two patches of

Better to take it as a separate patchset, as the rest of the original
patchset is probably settled.
This patchset is taking care of incorrect usage of internal NLA_* values
in uapi, introduces new enum (in patch #2) that shadows NLA_* values and
makes that part of UAPI.
The last two patches removes unnecessary translations with maintaining
clear devlink param driver api.

Devlink param and health reporter fmsg use attributes with dynamic type
which is determined according to a different type. Currently used values
are NLA_*. The problem is, they are not part of UAPI. They may change
which would cause a break.
To make this future safe, introduce a enum that shadows NLA_* values in
it and is part of UAPI.
Also, this allows to possibly carry types that are unrelated to NLA_*
values.

This happens because core::fmt::write() calls
core::fmt::rt::Argument::fmt(), which currently has CFI disabled:
library/core/src/fmt/rt.rs:
171 // FIXME: Transmuting formatter in new and indirectly branching to/calling
172 // it here is an explicit CFI violation.
173 #[allow(inline_no_sanitize)]
174 #[no_sanitize(cfi, kcfi)]
175 #[inline]
176 pub(super) unsafe fn fmt(&self, f: &mut Formatter<'_>) -> Result {
This causes a Control Protection exception, because FineIBT has sealed
off the original function's endbr64.
This makes rust currently incompatible with FineIBT. Add a Kconfig
dependency that prevents FineIBT from getting turned on by default
if rust is enabled.
[ Rust 1.88.0 (scheduled for 2025-06-26) should have this fixed [1],
and thus we relaxed the condition with Rust >= 1.88.
When `objtool` lands checking for this with e.g. [2], the plan is
to ideally run that in upstream Rust's CI to prevent regressions
early [3], since we do not control `core`'s source code.
Alice tested the Rust PR backported to an older compiler.
Peter would like that Rust provides a stable `core` which can be
pulled into the kernel: "Relying on that much out of tree code is
'unfortunate'".

Starting with Rust 1.88.0 (expected 2025-06-26) [1], `rustc` may move
back the `uninlined_format_args` to `style` from `pedantic` (it was
there waiting for rust-analyzer suppotr), and thus we will start to see
lints like:
warning: variables can be used directly in the `format!` string
--> rust/macros/kunit.rs:105:37
|
105 | let kunit_wrapper_fn_name = format!("kunit_rust_wrapper_{}", test);

|
105 - let kunit_wrapper_fn_name = format!("kunit_rust_wrapper_{}", test);
105 + let kunit_wrapper_fn_name = format!("kunit_rust_wrapper_{test}");
There is even a case that is a pure removal:
warning: variables can be used directly in the `format!` string
--> rust/macros/module.rs:51:13
|
51 | format!("{field}={content}\0", field = field, content = content)
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

help: change this to
|
51 - format!("{field}={content}\0", field = field, content = content)
51 + format!("{field}={content}\0")
The lints all seem like nice cleanups, thus just apply them.
We may want to disable `allow-mixed-uninlined-format-args` in the future.

Starting with Rust 1.88.0 (expected 2025-06-26) [1], Clippy may start
warning about paths that do not resolve in the `disallowed_macros`
configuration:
warning: `kernel::dbg` does not refer to an existing macro
--> .clippy.toml:10:5
|
10 | { path = "kernel::dbg", reason = "the `dbg!` macro is intended as a debugging tool" },
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This is a lint we requested at [2], due to the trouble debugging
the lint due to false negatives (e.g. [3]), which we use to emulate
`clippy::dbg_macro` [4]. See commit 8577c9dca7 ("rust: replace
`clippy::dbg_macro` with `disallowed_macros`") for more details.
Given the false negatives are not resolved yet, it is expected that
Clippy complains about not finding this macro.
Thus, until the false negatives are fixed (and, even then, probably we
will need to wait for the MSRV to raise enough), use the escape hatch
to allow an invalid path.

Starting with Rust 1.88.0 (expected 2025-06-26) [1][2], `rustc` may
introduce a new lint that catches unnecessary transmutes, e.g.:
error: unnecessary transmute
--> rust/uapi/uapi_generated.rs:23242:18
|
23242 | unsafe { ::core::mem::transmute(self._bitfield_1.get(0usize, 1u8) as u8) }
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: replace this with: `(self._bitfield_1.get(0usize, 1u8) as u8 == 1)`
|
= note: `-D unnecessary-transmutes` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(unnecessary_transmutes)]`
There are a lot of them (at least 300), but luckily they are all in
`bindgen`-generated code.
Thus clean all up by allowing it there.
Since unknown lints trigger a lint itself in older compilers, do it
conditionally so that we can keep the `unknown_lints` lint enabled.

Starting with Rust 1.87.0 (expected 2025-05-15), `objtool` may report:
rust/core.o: warning: objtool: _R..._4core9panicking9panic_fmt() falls
through to next function _R..._4core9panicking18panic_nounwind_fmt()
rust/core.o: warning: objtool: _R..._4core9panicking18panic_nounwind_fmt()
falls through to next function _R..._4core9panicking5panic()
The reason is that `rust_begin_unwind` is now mangled:
_R..._7___rustc17rust_begin_unwind
Thus add the mangled one to the list so that `objtool` knows it is
actually `noreturn`.
See commit 56d680dd23 ("objtool/rust: list `noreturn` Rust functions")
for more details.
Alternatively, we could remove the fixed one in `noreturn.h` and relax
this test to cover both, but it seems best to be strict as long as we can.

If cgroup_has_attached_progs queries an attach type not supported
by the running kernel, due to the kernel being older than the bpftool
build, it would encounter an -EINVAL from BPF_PROG_QUERY syscall.
Prior to commit 98b303c9bf ("bpftool: Query only cgroup-related
attach types"), this EINVAL would be ignored by the function, allowing
the function to only consider supported attach types. The commit
changed so that, instead of querying all attach types, only attach
types from the array `cgroup_attach_types` is queried. The assumption
is that because these are only cgroup attach types, they should all
be supported. Unfortunately this assumption may be false when the
kernel is older than the bpftool build, where the attach types queried
by bpftool is not yet implemented in the kernel. This would result in
errors such as:
$ bpftool cgroup tree
CgroupPath
ID AttachType AttachFlags Name
Error: can't query bpf programs attached to /sys/fs/cgroup: Invalid argument
This patch restores the logic of ignoring EINVAL from prior to that patch.
