6ad8de3cef ipv4: start using dst_dev_rcu()
Change icmpv4_xrlim_allow(), ip_defrag() to prevent possible UAF.

Change ipmr_prepare_xmit(), ipmr_queue_fwd_xmit(), ip_mr_output(),
ipv4_neigh_lookup() to use lockdep enabled dst_dev_rcu().

Eric Dumazet says:

====================
inet_diag: make dumps faster with simple filters

inet_diag_bc_sk() pulls five cache lines per socket,
while most filters only need the two first ones.

We can change it to only pull needed cache lines,
to make things like "ss -temoi src :21456" much faster.

First patches (1-3) are annotating data-races as a first step.

95fa78830e inet_diag: avoid cache line misses in inet_diag_bc_sk()
inet_diag_bc_sk() pulls five cache lines per socket,
while most filters only need the two first ones.

Add three booleans to struct inet_diag_dump_data,
that are selectively set if a filter needs specific socket fields.

- mark_needed       /* INET_DIAG_BC_MARK_COND present. */
- cgroup_needed     /* INET_DIAG_BC_CGROUP_COND present. */
- userlocks_needed  /* INET_DIAG_BC_AUTO present. */

This removes millions of cache lines misses per ss invocation
when simple filters are specified on busy servers.

offsetof(struct sock, sk_userlocks) = 0xf3
offsetof(struct sock, sk_mark) = 0x20c
offsetof(struct sock, sk_cgrp_data) = 0x298

0704a3da7c mISDN: Fix memory leak in dsp_hwec_enable()
dsp_hwec_enable() allocates dup pointer by kstrdup(arg),
but then it updates dup variable by strsep(&dup, ",").
As a result when it calls kfree(dup), the dup variable may be
a modified pointer that no longer points to the original allocated
memory, causing a memory leak.

The issue is the same pattern as fixed in commit c6a502c229
("mISDN: Fix memory leak in dsp_pipeline_build()").

34c21e9119 microchip: lan865x: add ndo_eth_ioctl handler to enable PHY ioctl support
Introduce support for standard MII ioctl operations in the LAN865x
Ethernet driver by implementing the .ndo_eth_ioctl callback. This allows
PHY-related ioctl commands to be handled via phy_do_ioctl_running() and
enables support for ethtool and other user-space tools that rely on ioctl
interface to perform PHY register access using commands like SIOCGMIIREG
and SIOCSMIIREG.

This feature enables improved diagnostics and PHY configuration
capabilities from userspace.

8bf935cf78 ptp: ocp: fix use-after-free bugs causing by ptp_ocp_watchdog
The ptp_ocp_detach() only shuts down the watchdog timer if it is
pending. However, if the timer handler is already running, the
timer_delete_sync() is not called. This leads to race conditions
where the devlink that contains the ptp_ocp is deallocated while
the timer handler is still accessing it, resulting in use-after-free
bugs. The following details one of the race scenarios.

(thread 1)                           | (thread 2)
ptp_ocp_remove()                     |
  ptp_ocp_detach()                   | ptp_ocp_watchdog()
    if (timer_pending(&bp->watchdog))|   bp = timer_container_of()
      timer_delete_sync()            |
                                     |
  devlink_free(devlink) //free       |
                                     |   bp-> //use

Resolve this by unconditionally calling timer_delete_sync() to ensure
the timer is reliably deactivated, preventing any access after free.

b79e498080 xirc2ps_cs: fix register access when enabling FullDuplex
The current code incorrectly passes (XIRCREG1_ECR | FullDuplex) as
the register address to GetByte(), instead of fetching the register
value and OR-ing it with FullDuplex. This results in an invalid
register access.

Fix it by reading XIRCREG1_ECR first, then or-ing with FullDuplex
before writing it back.

2) Better error reporting when a helper module clashes with

   the module is already loaded, so error message is elided.

d6a367ec6c netfilter: nft_flowtable.sh: re-run with random mtu sizes
Jakub says:
 nft_flowtable.sh is one of the most flake-atious test for netdev CI currently :(

The root cause is two-fold:
1. the failing part of the test is supposed to make sure that ip
   fragments are forwarded for offloaded flows.
   (flowtable has to pass them to classic forward path).
   path mtu discovery for these subtests is disabled.

2. nft_flowtable.sh has two passes.  One with fixed mtus/file size and
  one where link mtus and file sizes are random.

The CI failures all have same pattern:
  re-run with random mtus and file size: -o 27663 -l 4117 -r 10089 -s 54384840
  [..]
  PASS: dscp_egress: dscp packet counters match
  FAIL: file mismatch for ns1 -> ns2

In some cases this error triggers a bit ealier, sometimes in a later
subtest:
  re-run with random mtus and file size: -o 20201 -l 4555 -r 12657 -s 9405856
  [..]
  PASS: dscp_egress: dscp packet counters match
  PASS: dscp_fwd: dscp packet counters match
  2025/08/17 20:37:52 socat[18954] E write(7, 0x560716b96000, 8192): Broken pipe
  FAIL: file mismatch for ns1 -> ns2
  -rw------- 1 root root 9405856 Aug 17 20:36 /tmp/tmp.2n63vlTrQe

But all logs I saw show same scenario:
1. Failing tests have pmtu discovery off (i.e., ip fragmentation)
2. The test file is much larger than first-pass default (2M Byte)
3. peers have much larger MTUs compared to the 'network'.

These errors are very reproducible when re-running the test with
the same commandline arguments.

The timeout became much more prominent with
1d2fbaad7c ("tcp: stronger sk_rcvbuf checks"): reassembled packets
typically have a skb->truesize more than double the skb length.

As that commit is intentional and pmtud-off with
large-tcp-packets-as-fragments is not normal adjust the test to use a
smaller file for the pmtu-off subtests.

While at it, add more information to pass/fail messages and
also run the dscp alteration subtest with pmtu discovery enabled.

Convert the Broadcom iProc/Cygnus GPIO/Pinconf binding to DT schema
format.

The child node structure is based on the example as there's not any
actual .dts files with child nodes.

The binding wasn't clear that "reg" can be 1 or 2 entries. The number of
"reg" entries doesn't appear to be based on compatible, so no per
compatible constraints for it

The "brcm,iproc-stingray-gpio" could possibly be dropped. There are no
.dts files using it, but the driver uses it.

c67a9f492c Merge branch 'mauro' into docs-mw
Another build series from Mauro:

The goal of this series is to drop one of the most ancient and ugliest
hack from the documentation build system. Before migrating to Sphinx,
the media subsystem already had a very comprehensive uAPI book, together
with a build time system to detect and point for any documentation gaps.

When migrating to Sphinx, we ported the logic to a Perl script
(parse-headers.pl) and Markus came up with a Sphinx extension
(kernel_include.py). We also added some files to control how parse-headers
produce results, and a Makefile.

At the initial Sphinx versions (1.4.1 if I recall correctly), when
a new symbol is added to videodev2.h, a new warning were
produced at documentatiion time, it the patchset didn't have
the corresponding documentation path.

While kernel-include is generic, the only user at the moment is the media
subsystem.

This series gets rid of the Python script, replacing it by a command
line script and a class. The parse header class can optionally be used by
kernel-include to produce an enriched code that will contain cross-references.

As the other conversions, it starts with a bug-compatible version of
parse-headers, but the subsequent patches add more functionalities and
fix bugs.

It should be noticed that modern of Sphinx disabled the cross-reference
warnings. So, at the next series, I'll be re-adding it in a controlled way
(e.g. just for the references from kernel-include that has an special
argument).

The script also supports now generating a "toc" output, which will be used
at the next series.

428c1d3511 docs: kernel_include.py: remove Include class inheritance
While the original code came from the Sphinx Include class,
such class is monolithic: it has only one function that does
everything, and 3 variables that are used:

	- required_arguments
	- optional_arguments
	- option_spec

So, basically those are the only members that remain from
the original class, but hey! Those are the same vars that every
other Sphinx directive extension has to define!

In summary, keeping inheritance here doesn't make much sense.

Worse than that, kernel-include doesn't support the current set
of options that the original Include class has, but it also
has its own set of options.

So, let's fill in the argument vars with what it does
support, dropping the rest.
