Previously, an ethtool rx flow with no attrs would not be added to the
NIC as it has no rules to configure the hw with, but it would be
reported as successful to the caller (return code 0). This is confusing
for the user as ethtool then reports "Added rule $num", but no rule was
actually added.
This change corrects that by instead reporting these wrong rules as
-EINVAL.

During latency tests (netperf TCP_RR) a 30% degradation of HW GRO vs SW
GRO was observed. This is due to SHAMPO triggering timeout filler CQEs
instead of delivering the CQE for the packet.
Having a short timeout for SHAMPO doesn't bring any benefits as it is
the driver that does the merging, not the hardware. On the contrary, it
can have a negative impact: additional filler CQEs are generated due to
the timeout. As there is no way to disable this timeout, this change
sets it to the maximum value.
Instead of using the packet_merge.timeout parameter which is also used
for LRO, set the value directly when filling in the rest of the SHAMPO
parameters in mlx5e_build_rq_param().

In commit 10154dbded ("udp: Allow GSO transmit from devices with no
checksum offload") we have intentionally allowed UDP GSO packets marked
CHECKSUM_NONE to pass to the GSO stack, so that they can be segmented and
checksummed by a software fallback when the egress device lacks these
features.
What was not taken into consideration is that a CHECKSUM_NONE skb can be
handed over to the GSO stack also when the egress device advertises the
tx-udp-segmentation / NETIF_F_GSO_UDP_L4 feature.
This will happen when there are IPv6 extension headers present, which we
check for in __ip6_append_data(). Syzbot has discovered this scenario,
producing a warning as below:

We are hitting the bad offload warning because when an egress device is
capable of handling segmentation offload requested by
skb_shinfo(skb)->gso_type, the chain of gso_segment callbacks won't produce
any segment skbs and return NULL. See the skb_gso_ok() branch in
{__udp,tcp,sctp}_gso_segment helpers.
To fix it, force a fallback to software USO when processing a packet with
IPv6 extension headers, since we don't know if these can checksummed by
all devices which offer USO.

UDP segmentation offload inherently depends on checksum offload. It should
not be possible to disable checksum offload while leaving USO enabled.
Enforce this dependency in code.
There is a single tx-udp-segmentation feature flag to indicate support for
both IPv4/6, hence the devices wishing to support USO must offer checksum
offload for both IP versions.

Commit 04d82a6d08 ("binfmt_flat: allow not offsetting data start")
introduced a RISC-V specific variant of the FLAT format which does
not allocate any space for the (obsolete) array of shared library
pointers. However, it did not disable the code which initializes the
array, resulting in the corruption of sizeof(long) bytes before the DATA
segment, generally the end of the TEXT segment.
Introduce MAX_SHARED_LIBS_UPDATE which depends on the state of
CONFIG_BINFMT_FLAT_NO_DATA_START_OFFSET to guard the initialization of
the shared library pointer region so that it will only be initialized
if space is reserved for it.

LLVM 19 is dropping support for 3DNow! in commit f0eb5587ceeb ("Remove
support for 3DNow!, both intrinsics and builtins. (#96246)"):
Remove support for 3DNow!, both intrinsics and builtins. (#96246)
This set of instructions was only supported by AMD chips starting in
the K6-2 (introduced 1998), and before the "Bulldozer" family
(2011). They were never much used, as they were effectively superseded
by the more-widely-implemented SSE (first implemented on the AMD side
in Athlon XP in 2001).
This is being done as a predecessor towards general removal of MMX
register usage. Since there is almost no usage of the 3DNow!
intrinsics, and no modern hardware even implements them, simple
removal seems like the best option.
Thus we should avoid passing these to the backend, since otherwise we
get a diagnostic about it:
'-3dnow' is not a recognized feature for this target (ignoring feature)
'-3dnowa' is not a recognized feature for this target (ignoring feature)
We could try to disable them only up to LLVM 19 (not the C side one,
but the one used by `rustc`, which may be built with a range of
LLVMs). However, to avoid more complexity, we can likely just remove
them altogether. According to Nikita [2]:
> I don't think it's needed because LLVM should not generate 3dnow
> instructions unless specifically asked to, using intrinsics that
> Rust does not provide in the first place.
Thus do so, like Rust did for one of their builtin targets [3].
For those curious: Clang will warn only about trying to enable them
(`-m3dnow{,a}`), but not about disabling them (`-mno-3dnow{,a}`), so
there is no change needed there.

GCC 14 recently added -fmin-function-alignment option and the
root Makefile uses it to replace -falign-functions when available.
However, this flag can cause issues when passed to the Rust
Makefile and affect the bindgen process. Bindgen relies on
libclang to parse C code, and currently does not support the
-fmin-function-alignment flag, leading to compilation failures
when GCC 14 is used.
This patch addresses the issue by adding -fmin-function-alignment
to the bindgen_skip_c_flags in rust/Makefile. This prevents the
flag from causing compilation issues.
[ Matthew and Gary confirm function alignment should not change
the ABI in a way that bindgen would care about, thus we did
not need the extra logic for bindgen from v2. - Miguel ]

to mount DAX filesystem fails with this error:

missing codepage or helper program, or other error.
dmesg(1) may have more information after failed mount system call.

cpufreq: intel_pstate: Update Balance performance EPP for Emerald Rapids
There are two more changes to the syscall.tbl conversion: the
'__NR_newfstat' in the previous bugfix was a mistake and gets reverted
now, after triple-checking that the contents are now back to what they
were on all architectures. The __NR_nfsservctl definition is not really
needed but came up in the same discussion as it had previously been
defined in uapi/asm-generic/unistd.h and tested for in user space.
TThere are a few more symbols that used to be defined in the old
unistd.h file, but that are never defined on any other architecture
using syscall.tbl format. These used to be needed inside of the kernel:
__NR_syscalls
__NR_arch_specific_syscall
__NR3264_*
Searching for these on https://codesearch.debian.net/ shows a few packages
(rustc, golang, clamav, libseccomp, librsvg, strace) that duplicate all
the macros from asm/unistd.h, but nothing that actually uses the macros,
so I concluded that they are fine to omit after all.

When running the following:

# echo 0 > tracing_on
# dd if=per_cpu/cpu0/trace_pipe_raw of=/tmp/raw0.dat
The dd task would get stuck in an infinite loop in the kernel. What would
happen is the following:
When ring_buffer_read_page() returns -1 (no data) then a check is made to
see if the buffer is empty (as happens when the page is not full), it will
call wait_on_pipe() to wait until the ring buffer has data. When it is it
will try again to read data (unless O_NONBLOCK is set).
The issue happens when there's a reader and the file descriptor is closed.
The wait_on_pipe() will return when that is the case. But this loop will
continue to try again and wait_on_pipe() will again return immediately and
the loop will continue and never stop.
Simply check if the file was closed before looping and exit out if it is.

The recursive aes-arm-bs module load situation reported by Russell King
is getting fixed in the crypto layer, but this in the meantime fixes the
"recursive load hangs forever" by just making the waiting for the first
module load be interruptible.
This should now match the old behavior before commit 9b9879fc03
("modules: catch concurrent module loads, treat them as idempotent"),
which used the different "wait for module to be ready" code in
module_patient_check_exists().
End result: a recursive module load will still block, but now a signal
will interrupt it and fail the second module load, at which point the
first module will successfully complete loading.

Merge tag 'i2c-host-fixes-6.11-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-current
Two fixes on the Qualcomm GENI I2C controller are cleaning up the
error exit patch in the runtime_resume() function. The first is
disabling the clock, the second disables the icc on the way out.
Apart from the standard "configurations", "interfaces" and "alternate
interface settings" in USB, iOS devices also have a notion of
"modes". In different modes, the device exposes a different set of
available configurations.
Depending on the iOS version, and depending on the current mode, the
length and contents of the carrier state control message differs:
* 1 byte (seen on iOS 4.2.1, 8.4):
* 03: carrier off (mode 0)
* 04: carrier on (mode 0)
* 3 bytes (seen on iOS 10.3.4, 15.7.6):
* 03 03 03: carrier off (mode 0)
* 04 04 03: carrier on (mode 0)
* 4 bytes (seen on iOS 16.5, 17.6):
* 03 03 03 00: carrier off (mode 0)
* 04 03 03 00: carrier off (mode 1)
* 06 03 03 00: carrier off (mode 4)
* 04 04 03 04: carrier on (mode 0 and 1)
* 06 04 03 04: carrier on (mode 4)
Before this change, the driver always used the first byte of the
response to determine carrier state.
From this larger sample, the first byte seems to indicate the number of
available USB configurations in the current mode (with the exception of
the default mode 0), and in some cases (namely mode 1 and 4) does not
correlate with the carrier state.
Previous logic erroneously counted `04 03 03 00` as "carrier on" and
`06 04 03 04` as "carrier off" on iOS versions that support mode 1 and
mode 4 respectively.
Only modes 0, 1 and 4 expose the USB Ethernet interfaces necessary for
the ipheth driver.
Check the second byte of the control message where possible, and fall
back to checking the first byte on older iOS versions.

RX callbacks can fail for multiple reasons:
* Payload too short
* Payload formatted incorrecly (e.g. bad NCM framing)
* Lack of memory
None of these should cause the driver to seize up.
Make such failures non-critical and continue processing further
incoming URBs.

On iPhone 15 Pro Max one can observe periodic URBs with no payload
on the "bulk in" (RX) endpoint. These don't seem to do anything
meaningful. Reproduced on iOS 17.5.1 and 17.6.
This behaviour isn't observed on iPhone 11 on the same iOS version. The
nature of these zero-length URBs is so far unknown.
Drop RX URBs with no payload.

Rx URB length was already checked in ipheth_rcvbulk_callback_legacy()
and ipheth_rcvbulk_callback_ncm(), depending on the current mode.
The check in ipheth_rcvbulk_callback() was thus mostly a duplicate.
The only place in ipheth_rcvbulk_callback() where we care about the URB
length is for the initial control frame. These frames are always 4 bytes
long. This has been checked as far back as iOS 4.2.1 on iPhone 3G.
Remove the extraneous URB length check. For control frames, check for
the specific 4-byte length instead.

ipheth_sndbulk_callback() can submit carrier_work
as a part of its error handling. That means that
the driver must make sure that the work is cancelled
after it has made sure that no more URB can terminate
with an error condition.
Hence the order of actions in ipheth_close() needs
to be inverted.

the prefix paths from it are fully accessible.
