Dmitry Safonov edbac739e4 selftests/net: Drop timeout argument from test_client_verify()
It's always TEST_TIMEOUT_SEC, with an unjustified exception in rst test,
that is more paranoia-long timeout rather than based on requirements.

Dmitry Safonov 3f36781e57 selftests/net: Add mixed select()+polling mode to TCP-AO tests
Currently, tcp_ao tests have two timeouts: TEST_RETRANSMIT_SEC and
TEST_TIMEOUT_SEC [by default 1 and 5 seconds]. The first one,
TEST_RETRANSMIT_SEC is used for operations that are expected to succeed
in order for a test to pass. It is usually not consumed and exists only
to avoid indefinite test run if the operation didn't complete.
The second one, TEST_RETRANSMIT_SEC exists for the tests that checking
operations, that are expected to fail/timeout. It is shorter as it is
fully consumed, with an expectation that if operation didn't succeed
during that period, it will timeout. And the related test that expects
the timeout is passing. The actual operation failure is then
cross-verified by other means like counters checks.

The issue with TEST_RETRANSMIT_SEC timeout is that 1 second is the exact
initial TCP timeout. So, in case the initial segment gets lost (quite
unlikely on local veth interface between two net namespaces, yet happens
in slow VMs), the retransmission never happens and as a result, the test
is not actually testing the functionality. Which in the end fails
counters checks.

As I want tcp_ao selftests to be fast and finishing in a reasonable
amount of time on manual run, I didn't consider increasing
TEST_RETRANSMIT_SEC.

Rather, initially, BPF_SOCK_OPS_TIMEOUT_INIT looked promising as a lever
to make the initial TCP timeout shorter. But as it's not a socket bpf
attached thing, but sock_ops (attaches to cgroups), the selftests would
have to use libbpf, which I wanted to avoid if not absolutely required.

Instead, use a mixed select() and counters polling mode with the longer
TEST_TIMEOUT_SEC timeout to detect running-away failed tests. It
actually not only allows losing segments and succeeding after
the previous TEST_RETRANSMIT_SEC timeout was consumed, but makes
the tests expecting timeout/failure pass faster.

The only test case taking longer (TEST_TIMEOUT_SEC) now is connect-deny
"wrong snd id", which checks for no key on SYN-ACK for which there is no
counter in the kernel (see tcp_make_synack()). Yet it can be speed up
by poking skpair from the trace event (see trace_tcp_ao_synack_no_key).

Dmitry Safonov 5a0a3193f6 selftests/net: Fetch and check TCP-MD5 counters
There are related TCP-MD5 <=> TCP and TCP-MD5 <=> TCP-AO tests
that can benefit from checking the related counters, not only from
validating operations timeouts.

It also prepares the code for introduction of mixed select()+poll mode,

Dmitry Safonov 1fe4221093 selftests/net: Provide tcp-ao counters comparison helper
Rename __test_tcp_ao_counters_cmp() into test_assert_counters_ao() and
test_tcp_ao_key_counters_cmp() into test_assert_counters_key() as they
are asserts, rather than just compare functions.

Provide test_cmp_counters() helper, that's going to be used to compare
ao_info and netns counters as a stop condition for polling the sockets.

Dmitry Safonov 65ffdf31be selftests/net: Print TCP flags in more common format
Before:
># 13145[lib/ftrace-tcp.c:427] trace event filter tcp_ao_key_not_found [2001:db8:1::1:-1 => 2001:db8:254::1:7010, L3index 0, flags: !FS!R!P!., keyid: 100, rnext: 100, maclen: -1, sne: -1] = 1

After:
># 13487[lib/ftrace-tcp.c:427] trace event filter tcp_ao_key_not_found [2001:db8:1::1:-1 => 2001:db8:254::1:7010, L3index 0, flags: S, keyid: 100, rnext: 100, maclen: -1, sne: -1] = 1

For the history, I think the initial format was to emphasize the absence
of flags as well as their presence (!R meant no RST flag). But looking
again, it's just unreadable and hard to understand.
Make it the standard/expected one.

Intel Wired LAN Driver Updates 2025-03-18 (ice, idpf)

For ice:

Przemek modifies string declarations to resolve compile issues on gcc 7.5.

Karol adds padding to initial programming of GLTSYN_TIME* registers to
ensure it will occur in the future to prevent hardware issues.

Jesse Brandeburg turns off driver RDMA capability when the corresponding
kernel config is not enabled to aid in preventing resource exhaustion.

Jan adjusts type declaration to properly catch error conditions and
prevent truncation of values. He also adds bounds checking to prevent
overflow in ice_vc_cfg_q_quanta().

Lukasz adds checking and error reporting for invalid values in
ice_vc_cfg_q_bw().

Mateusz adds check for valid size for ice_vc_fdir_parse_raw().

For idpf:

Emil adds check, and handling, on failure to register netdev.

Imre Deak 55d657da8e drm/i915/dp_mst: Fix side-band message timeouts due to long PPS delays
The Panel Power Sequencer lock held on an eDP port (a) blocks a DP AUX
transfer on another port (b), since the PPS lock is device global, thus
shared by all ports. The PPS lock can be held on port (a) for a longer
period due to the various PPS delays (panel/backlight on/off,
power-cycle delays). This in turn can cause an MST down-message request
on port (b) time out, if the above PPS delay defers the handling of the
reply to the request by more than 100ms: the MST branch device sending
the reply (signaling this via the DP_DOWN_REP_MSG_RDY flag in the
DP_DEVICE_SERVICE_IRQ_VECTOR DPCD register) may cancel the reply
(clearing DP_DOWN_REP_MSG_RDY and the reply message buffer) after 110
ms, if the reply is not processed by that time.

Avoid MST down-message timeouts described above, by locking the PPS
state for AUX transfers only if this is actually required: on eDP ports,
where the VDD power depends on the PPS state and on all DP and eDP ports
on VLV/CHV, where the PPS is a pipe instance and hence a modeset on any
port possibly affecting the PPS state.

v2: Don't move PPS locking/VDD enabling to a separate function. (Jani)

Simon Horman 6165feda3d net: tulip: avoid unused variable warning
There is an effort to achieve W=1 kernel builds without warnings.
As part of that effort Helge Deller highlighted the following warnings
in the tulip driver when compiling with W=1 and CONFIG_TULIP_MWI=n:

  .../tulip_core.c: In function ‘tulip_init_one’:
  .../tulip_core.c:1309:22: warning: variable ‘force_csr0’ set but not used

This patch addresses that problem using IS_ENABLED(). This approach has
the added benefit of reducing conditionally compiled code. And thus
increasing compile coverage. E.g. for allmodconfig builds which enable
CONFIG_TULIP_MWI.

Compile tested only.
No run-time effect intended.

Kuniyuki Iwashima 0083e3e37e af_unix: Clean up #include under net/unix/.
net/unix/*.c include many unnecessary header files (rtnetlink.h,
netdevice.h, etc).

Let's clean them up.

af_unix.c:

  +uapi/linux/sockios.h   : Only exist under include/uapi
  +uapi/linux/termios.h   : Only exist under include/uapi

  -linux/freezer.h        : No longer use freezable_schedule_timeout()
  -linux/in.h             : No ipv4_is_XXX() etc
  -linux/module.h         : No longer support CONFIG_UNIX=m
  -linux/netdevice.h      : No dev used
  -linux/rtnetlink.h      : Not part of rtnetlink API
  -linux/signal.h         : signal_pending() is defined in sched/signal.h
  -linux/stat.h           : No struct stat used
  -net/checksum.h         : CHECKSUM_UNNECESSARY is defined in skbuff.h

diag.c:

  +linux/dcache.h         : struct dentry in sk_diag_dump_vfs()
  +linux/user_namespace.h : struct user_namespace in sk_diag_dump_uid()
  +uapi/linux/unix_diag.h : Only exist under include/uapi/

garbage.c:

  +linux/list.h           : struct unix_{vertex,edge}, etc
  +linux/workqueue.h      : DECLARE_WORK(unix_gc_work, ...)

  -linux/file.h           : No fget() etc
  -linux/kernel.h         : No cond_resched() etc
  -linux/netdevice.h      : No dev used

Kuniyuki Iwashima 3056172a26 af_unix: Explicitly include headers for non-pointer struct fields.
include/net/af_unix.h indirectly includes some definitions for structs.

Let's include such headers explicitly.

  linux/atomic.h   : scm_stat.nr_fds
  linux/net.h      : unix_sock.peer_wq
  linux/path.h     : unix_sock.path
  linux/spinlock.h : unix_sock.lock
  linux/wait.h     : unix_sock.peer_wake
  uapi/linux/un.h  : unix_address.name[]

linux/socket.h is removed as the structs there are not used directly,
and linux/un.h is clarified with uapi as un.h only exists under
include/uapi.

While at it, duplicate headers are removed from .c files.

net/af_unix.h is included by core and some LSMs, but most definitions

Jason Xing 9552f90835 tcp: support TCP_DELACK_MAX_US for set/getsockopt use
Support adjusting/reading delayed ack max for socket level by using
set/getsockopt().

This option aligns with TCP_BPF_DELACK_MAX usage. Considering that bpf
option was implemented before this patch, so we need to use a standalone
new option for pure tcp set/getsockopt() use.

Add WRITE_ONCE/READ_ONCE() to prevent data-race if setsockopt()
happens to write one value to icsk_delack_max while icsk_delack_max is
being read.

Jason Xing f38805c5d2 tcp: support TCP_RTO_MIN_US for set/getsockopt use
Support adjusting/reading RTO MIN for socket level by using set/getsockopt().

This new option has the same effect as TCP_BPF_RTO_MIN, which means it
doesn't affect RTAX_RTO_MIN usage (by using ip route...). Considering that
bpf option was implemented before this patch, so we need to use a standalone
new option for pure tcp set/getsockopt() use.

When the socket is created, its icsk_rto_min is set to the default
value that is controlled by sysctl_tcp_rto_min_us. Then if application
calls setsockopt() with TCP_RTO_MIN_US flag to pass a valid value, then
icsk_rto_min will be overridden in jiffies unit.

This patch adds WRITE_ONCE/READ_ONCE to avoid data-race around
icsk_rto_min.

Andres Traumann be8cd366be ALSA: hda/realtek: Bass speaker fixup for ASUS UM5606KA
This patch applies the ALC294 bass speaker fixup (ALC294_FIXUP_BASS_SPEAKER_15),
previously introduced in commit a7df7f909c ("ALSA: hda: improve bass
speaker support for ASUS Zenbook UM5606WA"), to the ASUS Zenbook UM5606KA.
This hardware configuration matches ASUS Zenbook UM5606WA, where DAC NID
0x06 was removed from the bass speaker (NID 0x15), routing both speaker
pins to DAC NID 0x03.

This resolves the bass speaker routing issue, ensuring correct audio
output on ASUS UM5606KA.

Ryo Takakura 61c39d8c83 lockdep: Fix wait context check on softirq for PREEMPT_RT
Since:

  0c1d7a2c2d ("lockdep: Remove softirq accounting on PREEMPT_RT.")

the wait context test for mutex usage within "in softirq context" fails
as it references @softirq_context:

    | wait context tests |
    --------------------------------------------------------------------------
                                   | rcu  | raw  | spin |mutex |
    --------------------------------------------------------------------------
                 in hardirq context:  ok  |  ok  |  ok  |  ok  |
  in hardirq context (not threaded):  ok  |  ok  |  ok  |  ok  |
                 in softirq context:  ok  |  ok  |  ok  |FAILED|

As a fix, add lockdep map for BH disabled section. This fixes the
issue by letting us catch cases when local_bh_disable() gets called
with preemption disabled where local_lock doesn't get acquired.
In the case of "in softirq context" selftest, local_bh_disable() was
being called with preemption disable as it's early in the boot.

[ boqun: Move the lockdep annotations into __local_bh_*() to avoid false
         positives because of unpaired local_bh_disable() reported by
	 Borislav Petkov and Peter Zijlstra, and make bh_lock_map
	 only exist for PREEMPT_RT. ]

[ mingo: Restored authorship and improved the bh_lock_map definition. ]
