On all platforms set_clock_selection() writes to a GRF register. This
requires certain clocks running and thus should happen before the
clocks are disabled.
This has been noticed on RK3576 Sige5, which hangs during system suspend
when trying to suspend the second network interface. Note, that
suspending the first interface works, because the second device ensures
that the necessary clocks for the GRF are enabled.

Creating FDB entries is possible from a non-initial user namespace when
having CAP_NET_ADMIN, yet, when deleting FDB entries, processes receive
an EPERM because the capability is always checked against the initial
user namespace. This restricts the FDB management from unprivileged
containers.
Drop the netlink_capable check in rtnl_fdb_del as it was originally
dropped in c5c351088a and reintroduced in 1690be63a2 without
intention.
This patch was tested using a container on GyroidOS, where it was
possible to delete FDB entries from an unprivileged user namespace and
private network namespace.

Apply the formatting guidelines introduced in the previous commit to
make the file `rustfmt`-clean again.
Reviewed-by: Benno Lossin <lossin@kernel.org>
Signed-off-by: Miguel Ojeda <ojeda@kernel.org>
`rustfmt`, by default, formats imports in a way that is prone to conflicts
while merging and rebasing, since in some cases it condenses several
items into the same line.
For instance, Linus mentioned [1] that the following case:
use crate::{
fmt,
page::AsPageIter,
};
is compressed by `rustfmt` into:
use crate::{fmt, page::AsPageIter};
which is undesirable.
Similarly, `rustfmt` may put several items in the same line even if the
braces span already multiple lines, e.g.:
use kernel::{
acpi, c_str,
device::{property, Core},
of, platform,
};
The options that control the formatting behavior around imports are
generally unstable, and `rustfmt` releases do not allow to use nightly
features, unlike the compiler and other Rust tooling [2].
For the moment, we can introduce a workaround to prevent `rustfmt`
from compressing the example above -- the "trailing empty comment":
use crate::{
fmt,
page::AsPageIter, //
};
which is reminiscent of the trailing comma behavior in other formatters.
We already used empty comments for formatting purposes in the past,
e.g. in commit b9b701fce4 ("rust: clarify the language unstable features
in use").
In addition, `rustfmt` actually reformats with a vertical layout (i.e. it
does not put two items in the same line) when seeing such a comment,
i.e. it doesn't just preserve the formatting, which is good in the sense
that we can use it to easily reformat some imports, since it matches
the style we generally want to have.
A Git merge driver would help (suggested by Gary and Wedson), though
maintainers would need to set it up, the diffs would still be larger
and the formatting rules for imports would remain hard to predict.
Thus document the style that we will follow in the coding guidelines
by introducing a new section and explain how the trailing empty comment
works there too.
We discussed the issue with upstream Rust in our usual Rust <-> Rust
for Linux meeting [3], and there have also been a few other discussions
in parallel in issues [4][5] and Zulip [6]. We will see what happens,
but upstream Rust has already created a subteam of `rustfmt` to try
to overcome the bandwidth issue [7], which is a good signal, and some
organization work has already started (e.g. tracking issues). We will
continue our discussions with them about it.

'state' parameter of mlx5e_accel_tx_ids_len() were NULL when called
from mlx5i_sq_xmit() and were causing kernel panics from that context.
Fix that by passing in a local empty mlx5e_accel_tx_state variable, thus
guaranteeing that 'accel' is never NULL. Also remove an unnecessary

Some network drivers assume this field is zero after napi_get_frags().
We must clear it in napi_reuse_skb() otherwise the following can happen:
1) A packet is received, and skb_shinfo(skb)->hwtstamps is populated
because a bit in the receive descriptor announced hwtstamp
availability for this packet.
2) Packet is given to gro layer via napi_gro_frags().
3) Packet is merged to a prior one held in GRO queues.
4) skb is saved after some cleanup in napi->skb via a call
to napi_reuse_skb().
5) Next packet is received 10 seconds later, gets the recycled skb
from napi_get_frags().
6) The receive descriptor does not announce hwtstamp availability.
Driver does not clear shinfo->hwtstamps.
7) We have in shinfo->hwtstamps an old timestamp.

When building with Clang 20 or newer, there are some objtool warnings
from unexpected fallthroughs to other functions:
vmlinux.o: warning: objtool: mlx5e_mpwrq_mtts_per_wqe() falls through to next function mlx5e_mpwrq_max_num_entries()
vmlinux.o: warning: objtool: mlx5e_mpwrq_max_log_rq_size() falls through to next function mlx5e_get_linear_rq_headroom()
LLVM 20 contains an (admittedly problematic [1]) optimization [2] to
convert divide by zero into the equivalent of __builtin_unreachable(),
which invokes undefined behavior and destroys code generation when it is
encountered in a control flow graph.
mlx5e_mpwrq_umr_entry_size() returns 0 in the default case of an
unrecognized mlx5e_mpwrq_umr_mode value. mlx5e_mpwrq_mtts_per_wqe(),
which is inlined into mlx5e_mpwrq_max_log_rq_size(), uses the result of
mlx5e_mpwrq_umr_entry_size() in a divide operation without checking for
zero, so LLVM is able to infer there will be a divide by zero in this
case and invokes undefined behavior. While there is some proposed work
to isolate this undefined behavior and avoid the destructive code
generation that results in these objtool warnings, code should still be
defensive against divide by zero.
As the WARN_ONCE() implies that an invalid value should be handled
gracefully, return 1 instead of 0 in the default case so that the
results of this division operation is always valid.

TX frames aren't padded and unknown memory is sent into the ether.
Theoretically, it isn't even guaranteed that the extra memory exists
and can be sent out, which could cause further problems. In practice,
I found that plenty of tailroom exists in the skb itself (in my test
with ping at least) and skb_padto() easily succeeds, so use it here.
In the event of -ENOMEM drop the frame like other drivers do.
The use of one more padding byte instead of a USB zero-length packet
is retained to avoid regression. I have a dodgy Etron xHCI controller
which doesn't seem to support sending ZLPs at all.

With TLS enabled, records that are encrypted and appended to TLS TX
list can fail to see a retry if the underlying TCP socket is busy, for
example, hitting an EAGAIN from tcp_sendmsg_locked(). This is not known
to the NVMe TCP driver, as the TLS layer successfully generated a record.
Typically, the TLS write_space() callback would ensure such records are
retried, but in the NVMe TCP Host driver, write_space() invokes
nvme_tcp_write_space(). This causes a partially sent record in the TLS TX
list to timeout after not being retried.
This patch fixes the above by calling queue->write_space(), which calls
into the TLS layer to retry any pending records.

Michal reported and bisected an issue after recent adoption
of skb_attempt_defer_free() in UDP.
The issue here is that skb_release_head_state() is called twice per skb,
one time from skb_consume_udp(), then a second time from skb_defer_free_flush()
and napi_consume_skb().
As Sabrina suggested, remove skb_release_head_state() call from
skb_consume_udp().
Add a DEBUG_NET_WARN_ON_ONCE(skb_nfct(skb)) in skb_attempt_defer_free()
Many thanks to Michal, Sabrina, Paolo and Florian for their help.

Non dirmap reading works good. Looking to spi_mem_no_dirmap_read() code we'll see:
static ssize_t spi_mem_no_dirmap_read(struct spi_mem_dirmap_desc *desc,
u64 offs, size_t len, void *buf)
{
struct spi_mem_op op = desc->info.op_tmpl;
int ret;
// --- see here ---
op.addr.val = desc->info.offset + offs;
//-----------------
op.data.buf.in = buf;
op.data.nbytes = len;
ret = spi_mem_adjust_op_size(desc->mem, &op);
if (ret)
return ret;
ret = spi_mem_exec_op(desc->mem, &op);
if (ret)
return ret;
return op.data.nbytes;
}
The similar happens for spi_mem_no_dirmap_write(). Thus the address
passed to the flash should take in the account the value of
desc->info.offset.
This patch fix dirmap reading/writing of flashes with more than one
plane per lun.

If dirmap is disabled or not supported in the spi driver, the dirmap requests
will be executed via exec_op() handler. Thus, if the hardware supports
dual/quad spi modes, then corresponding requests will be sent to exec_op()
handler. Current driver does not support such requests, so error is arrised.
As result the flash can't be read/write.
This patch adds support of dual and quad wires spi modes to exec_op() handler.

This driver can accelerate single page operations only, thus
continuous reading mode should not be used.
Continuous reading will use sizes up to the size of one erase block.
This size is much larger than the size of single flash page. Use this

If obj_exts allocation failed, slab->obj_exts is set to OBJEXTS_ALLOC_FAIL,
But we do not clear it when freeing the slab. Since OBJEXTS_ALLOC_FAIL and
MEMCG_DATA_OBJEXTS currently share the same bit position, during the
release of the associated folio, a VM_BUG_ON_FOLIO() check in
folio_memcg_kmem() is triggered because the OBJEXTS_ALLOC_FAIL flag was
not cleared, causing it to be interpreted as a kmem folio (non-slab)
with MEMCG_OBJEXTS_DATA flag set, which is invalid because
MEMCG_OBJEXTS_DATA is supposed to be set only on slabs.
Another problem that predates sharing the OBJEXTS_ALLOC_FAIL and
MEMCG_DATA_OBJEXTS bits is that on configurations with
is_check_pages_enabled(), the non-cleared bit in page->memcg_data will
trigger a free_page_is_bad() failure "page still charged to cgroup"
When freeing a slab, we clear slab->obj_exts if the obj_ext array has
been successfully allocated. So let's clear it also when the allocation
has failed.

When adding dependencies with drm_sched_job_add_dependency(), that
function consumes the fence reference both on success and failure, so in
the latter case the dma_fence_put() on the error path (xarray failed to
expand) is a double free.
Interestingly this bug appears to have been present ever since
commit ebd5f74255 ("drm/sched: Add dependency tracking"), since the code
back then looked like this:
drm_sched_job_add_implicit_dependencies():
...
for (i = 0; i < fence_count; i++) {
ret = drm_sched_job_add_dependency(job, fences[i]);
if (ret)
break;
}
for (; i < fence_count; i++)
dma_fence_put(fences[i]);
Which means for the failing 'i' the dma_fence_put was already a double
free. Possibly there were no users at that time, or the test cases were
insufficient to hit it.
The bug was then only noticed and fixed after
commit 9c2ba26535 ("drm/scheduler: use new iterator in drm_sched_job_add_implicit_dependencies v2")
landed, with its fixup of
commit 4eaf02d607 ("drm/scheduler: fix drm_sched_job_add_implicit_dependencies").
At that point it was a slightly different flavour of a double free, which
commit 963d0b3569 ("drm/scheduler: fix drm_sched_job_add_implicit_dependencies harder")
noticed and attempted to fix.
But it only moved the double free from happening inside the
drm_sched_job_add_dependency(), when releasing the reference not yet
obtained, to the caller, when releasing the reference already released by
the former in the failure case.
As such it is not easy to identify the right target for the fixes tag so
lets keep it simple and just continue the chain.
While fixing we also improve the comment and explain the reason for taking
the reference and not dropping it.

detection reliability.
The changes focus on:
* Eliminating race conditions between jack insertion and ejection events
* Ensuring interrupts are consistently and correctly cleared before
unmasking
* Introducing a DMI-based quirk to bypass the jack debounce circuit on
Valve Steam Deck, improving detection accuracy under stress
* Improving robustness of the IRQ handler by avoiding unnecessary
blocking operations
The series has been tested on affected hardware to verify correct
behavior during repeated and rapid jack hotplug cycles.

This assert can trigger here with non pin_map users that select
LATE_RESTORE, since the vmap is allowed to be NULL given that
save/restore can now use the blitter instead. The check here doesn't
seem to have much value anymore given that we no longer move pinned
memory, so any existing vmap is left well alone, and doesn't need to be
recreated upon restore, so just drop the assert here.

If current bytes exceeds the max copy size, ensure the clamped size
still accounts for the XE_CACHELINE_BYTES alignment, otherwise we
trigger the assert in xe_migrate_vram with the size now being out of
alignment.

Kunit's generate_params() was recently updated to take an additional
test context parameter. Xe's IP and platform parameter generators were
updated accordingly at the same time, but the new parameter was not
added to the functions' kerneldoc, resulting in the following warnings:
Warning: drivers/gpu/drm/xe/tests/xe_pci.c:78 function parameter 'test' not described in 'xe_pci_fake_data_gen_params'

5 warnings as errors
Document the new parameter to eliminate the warnings and make CI happy.

If the location madvise() is set to
DRM_XE_PREFERRED_LOC_DEFAULT_SYSTEM, the drm_pagemap in the
SVM gpu fault handler will be set to NULL. However there is nothing
that explicitly migrates the data to system if it is already present
in device memory.
In that case, set the device memory owner to NULL to ensure
data gets properly migrated to system on page-fault.

Now that the SMB client accesses MD5, HMAC-MD5, HMAC-SHA256, and SHA-512
only via the library API and not via crypto_shash, allocating
crypto_shash objects for these algorithms is no longer necessary.
Remove all these allocations, their corresponding kconfig selections,
and their corresponding module soft dependencies.
