Isolate the Basic Mode Control Register (BMCR) operations in the ksz8795
driver by moving the BMCR-related code segments from the ksz8_r_phy()
and ksz8_w_phy() functions to newly created ksz8_r_phy_bmcr() and
ksz8_w_phy_bmcr() functions.

a total of 101 files changed, 6009 insertions(+), 1260 deletions(-).
The main changes are:
1) Add BPF token support to delegate a subset of BPF subsystem
functionality from privileged system-wide daemons such as systemd
through special mount options for userns-bound BPF fs to a trusted
& unprivileged application. With addressed changes from Christian
and Linus' reviews, from Andrii Nakryiko.
2) Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops type,
from Kui-Feng Lee.

net: phy: generic polarity + LED support for qca808x
This small series add LEDs support for qca808x.
QCA808x apply on PHY reset a strange polarity settings and require
some tweak to apply a more common configuration found on devices.
On adding support for it, it was pointed out that a similar
feature is also being implemented for a marvell PHY where
LED polarity is set per LED (and not global) and also have
a special mode where the LED is tristated.
The first 3 patch are to generalize this as we expect more PHY
in the future to have a similar configuration.
The implementation is extensible to support additional special
mode in the future with minimal changes and don't create regression
on already implemented PHY drivers.

Add LED support for QCA8081 PHY.
Documentation for this LEDs PHY is very scarce even with NDA access
to Documentation for OEMs. Only the blink pattern are documented and are
very confusing most of the time. No documentation is present about
forcing the LED on/off or to always blink.
Those settings were reversed by poking the regs and trying to find the
correct bits to trigger these modes. Some bits mode are not clear and
maybe the documentation option are not 100% correct. For the sake of LED
support the reversed option are enough to add support for current LED
APIs.
Supported HW control modes are:
- tx
- rx
- link_10
- link_100
- link_1000
- link_2500
- half_duplex
- full_duplex
Also add support for LED polarity set to set LED polarity to active
high or low. QSDK sets this value to high by default but PHY reset value
doesn't have this enabled by default.
QSDK also sets 2 additional bits but their usage is not clear, info about
this is added in the header. It was verified that for correct function
of the LED if active high is needed, only BIT 6 is needed.

Add support for PHY LEDs polarity modes. Some PHY require LED to be set
to active low to be turned ON. Adds support for this by declaring
active-low property in DT.
PHY driver needs to declare .led_polarity_set() to configure LED
polarity modes. Function will pass the index with the LED index and a
bitmap with all the required modes to set.
Current supported modes are:
- active-low with the flag PHY_LED_ACTIVE_LOW. LED is set to active-low
to turn it ON.
- inactive-high-impedance with the flag PHY_LED_INACTIVE_HIGH_IMPEDANCE.
LED is set to high impedance to turn it OFF.

A potential string truncation was reported in bnx2x_fill_fw_str(),
when a long bp->fw_ver and a long phy_fw_ver might coexist, but seems
unlikely with real-world hardware.
Use scnprintf() to indicate the intent that truncations are tolerated.
While reading this code, I found a collection of various buffer size
counting issues. None looked like they might lead to a buffer overflow
with current code (the small buffers are 20 bytes and might only ever
consume 10 bytes twice with a trailing %NUL). However, early truncation
(due to a %NUL in the middle of the string) might be happening under
likely rare conditions. Regardless fix the formatters and related
functions:
- Switch from a separate strscpy() to just adding an additional "%s" to
the format string that immediately follows it in bnx2x_fill_fw_str().
- Use sizeof() universally instead of using unbound defines.
- Fix bnx2x_7101_format_ver() and bnx2x_null_format_ver() to report the
number of characters written, not including the trailing %NUL (as
already done with the other firmware formatting functions).
- Require space for at least 1 byte in bnx2x_get_ext_phy_fw_version()
for the trailing %NUL.
- Correct the needed buffer size in bnx2x_3_seq_format_ver().

af_unix: Random improvements for GC.
If more than 16000 inflight AF_UNIX sockets exist on a host, each
sendmsg() will be forced to wait for unix_gc() even if a process
is not sending any FD.
This series tries not to impose such a penalty on sane users who
do not send AF_UNIX FDs or do not have inflight sockets more than
SCM_MAX_FD * 8.
The first patch can be backported to -stable.
Cleanup patches for commit 69db702c8387 ("io_uring/af_unix: disable

be followed later.

If more than 16000 inflight AF_UNIX sockets exist and the garbage
collector is not running, unix_(dgram|stream)_sendmsg() call unix_gc().
Also, they wait for unix_gc() to complete.
In unix_gc(), all inflight AF_UNIX sockets are traversed at least once,
and more if they are the GC candidate. Thus, sendmsg() significantly
slows down with too many inflight AF_UNIX sockets.
However, if a process sends data with no AF_UNIX FD, the sendmsg() call
does not need to wait for GC. After this change, only the process that
meets the condition below will be blocked under such a situation.
1) cmsg contains AF_UNIX socket
2) more than 32 AF_UNIX sent by the same user are still inflight
Note that even a sendmsg() call that does not meet the condition but has
AF_UNIX FD will be blocked later in unix_scm_to_skb() by the spinlock,
but we allow that as a bonus for sane users.
The results below are the time spent in unix_dgram_sendmsg() sending 1
byte of data with no FD 4096 times on a host where 32K inflight AF_UNIX
sockets exist.
Without series: the sane sendmsg() needs to wait gc unreasonably.

In unix_gc(), all inflight AF_UNIX sockets are traversed at least once,

slows down with too many inflight AF_UNIX sockets.
There is a small window to invoke multiple unix_gc() instances, which
will then be blocked by the same spinlock except for one.
Let's convert unix_gc() to use struct work so that it will not consume
CPUs unnecessarily.
Note WRITE_ONCE(gc_in_progress, true) is moved before running GC.
If we leave the WRITE_ONCE() as is and use the following test to
call flush_work(), a process might not call it.
CPU 0 CPU 1

start work and call __unix_gc()
if (work_pending(&unix_gc_work) || <-- false
READ_ONCE(gc_in_progress)) <-- false

Quoting from commit 4223f8651287 ("net: dsa: mt7530: make NET_DSA_MT7530
select MEDIATEK_GE_PHY"):
Make MediaTek MT753x DSA driver enable MediaTek Gigabit PHYs driver to
properly control MT7530 and MT7531 switch PHYs.
A noticeable change is that the behaviour of switchport interfaces going
up-down-up-down is no longer there.
Now, the switch can be used without the PHYs but, at the moment, every
hardware design out there that I have seen uses them. For that, it would
make the most sense to force the selection of MEDIATEK_GE_PHY for the MDIO
interface which currently controls the MT7530 and MT7531 switches.

In bpf_struct_ops_map_alloc, it needs to check for NULL in the returned
pointer of bpf_get_btf_vmlinux() when CONFIG_DEBUG_INFO_BTF is not set.
ENOTSUPP is used to preserve the same behavior before the
struct_ops kmod support.
In the function check_struct_ops_btf_id(), instead of redoing the
bpf_get_btf_vmlinux() that has already been done in syscall.c, the fix
here is to check for prog->aux->attach_btf_id.
BPF_PROG_TYPE_STRUCT_OPS must require attach_btf_id and syscall.c
guarantees a valid attach_btf as long as attach_btf_id is set.
When attach_btf_id is not set, this patch returns -ENOTSUPP
because it is what the selftest in test_libbpf_probe_prog_types()
and libbpf_probes.c are expecting for feature probing purpose.
Changes from v1:

For the longest time tdc ran only actions and qdiscs tests.
It's time to enable all the remaining tests so every user visible
piece of TC is tested by the downstream CIs.

If 'jq' is not available the taprio tests might enter an infinite loop,
use the "dependsOn" feature from tdc to check if jq is present. If it's
not the test is skipped.

- make sure init the accept_queue's spinlocks once
- fix autocork on CPUs with weak memory model
- udp: fix busy polling
- mlx5e:
- fix out-of-bound read in port timestamping

- iwlwifi: fix a memory corruption
Previous releases - always broken:
- netfilter:
- nft_chain_filter: handle NETDEV_UNREGISTER for inet/ingress
basechain
- nft_limit: reject configurations that cause integer overflow
- bpf: fix bpf_xdp_adjust_tail() with XSK zero-copy mbuf, avoiding a
NULL pointer dereference upon shrinking

Pull RCU fix from Neeraj Upadhyay:
"This fixes RCU grace period stalls, which are observed when an
outgoing CPU's quiescent state reporting results in wakeup of one of
the grace period kthreads, to complete the grace period.
If those kthreads have SCHED_FIFO policy, the wake up can indirectly
arm the RT bandwith timer to the local offline CPU.
Earlier migration of the hrtimers from the CPU introduced in commit
5c0930ccaad5 ("hrtimers: Push pending hrtimers away from outgoing CPU
earlier") results in this timer getting ignored.
If the RCU grace period kthreads are waiting for RT bandwidth to be
available, they may never be actually scheduled, resulting in RCU
stall warnings"

Currently the MDIO bus of the switches the MT7530 DSA subdriver controls
can only be registered as non-OF-based. Bring support for registering the
bus OF-based.
The subdrivers that control switches [with MDIO bus] probed on OF must
follow this logic to support all cases properly:
No switch MDIO bus defined: Populate ds->user_mii_bus, register the MDIO
bus, set the interrupts for PHYs if "interrupt-controller" is defined at
the switch node. This case should only be covered for the switches which
their dt-bindings documentation didn't document the MDIO bus from the
start. This is to keep supporting the device trees that do not describe the
MDIO bus on the device tree but the MDIO bus is being used nonetheless.
Switch MDIO bus defined: Don't populate ds->user_mii_bus, register the MDIO
bus, set the interrupts for PHYs if ["interrupt-controller" is defined at
the switch node and "interrupts" is defined at the PHY nodes under the
switch MDIO bus node].
Switch MDIO bus defined but explicitly disabled: If the device tree says
status = "disabled" for the MDIO bus, we shouldn't need an MDIO bus at all.
Instead, just exit as early as possible and do not call any MDIO API.
The use of ds->user_mii_bus is inappropriate when the MDIO bus of the
switch is described on the device tree [1], which is why we don't populate
ds->user_mii_bus in that case.

The fill ring of the XDP socket may contain not enough buffers to
completey fill the RX queue during socket creation. In this case the
flag XDP_RING_NEED_WAKEUP is not set as this flag is only set if the RX
queue is not completely filled during polling.
Set XDP_RING_NEED_WAKEUP flag also if RX queue is not completely filled
during XDP socket creation.

The RX data buffer includes the FCS. The FCS is already stripped for the
normal data path. But for the XDP data path the FCS is included and
acts like additional/useless data.
Remove the FCS from the RX data buffer also for XDP.

When repeatedly changing the interface link speed using the command below:
ethtool -s eth0 speed 100 duplex full
ethtool -s eth0 speed 1000 duplex full
The following errors may sometimes be reported by the ARM SMMU driver:
[ 5395.035364] fec 5b040000.ethernet eth0: Link is Down
[ 5395.039255] arm-smmu 51400000.iommu: Unhandled context fault:
fsr=0x402, iova=0x00000000, fsynr=0x100001, cbfrsynra=0x852, cb=2
[ 5398.108460] fec 5b040000.ethernet eth0: Link is Up - 100Mbps/Full -
flow control off
It is identified that the FEC driver does not properly stop the TX queue
during the link speed transitions, and this results in the invalid virtual
I/O address translations from the SMMU and causes the context faults.
