When the iavf driver wants to reconfigure the VLAN filters
(iavf_add_vlan, iavf_del_vlan), it sets a flag in
aq_required:
adapter->aq_required |= IAVF_FLAG_AQ_ADD_VLAN_FILTER;
or:
adapter->aq_required |= IAVF_FLAG_AQ_DEL_VLAN_FILTER;
This is later processed by the watchdog_task, but it runs periodically
every 2 seconds, so it can be a long time before it processes the request.
In the worst case, the interface is unable to receive traffic for more
than 2 seconds for no objective reason.

20s seems unnecessarily large for the DSP init timeout. This coupled with
multiple FW boot attempts causes an excessive delay in the error path when
booting in recovery mode. Reduce it to 0.5s and use the existing
HDA_DSP_INIT_TIMEOUT_US.

The microphone and speaker shutters on cs42l43 can be configured to
trigger from the same GPIO, in this case the current code returns an
error as we attempt to request two IRQ handlers for the same IRQ. Fix
this by always requesting the shutter IRQs with the IRQF_SHARED flag.

Prevent schedule operations for adminq during device remove and when
__IAVF_IN_REMOVE_TASK flag is set. Currently, the iavf_down function
adds operations for adminq that shouldn't be processed when the device
is in the __IAVF_REMOVE state.

Currently, if the OPEN compound experiencing an error and needs to
get the file attributes separately, it will send a stand alone
GETATTR but it would use the filehandle from the results of
the OPEN compound. In case of the CLAIM_FH OPEN, nfs_openres's fh
is zero value. That generate a GETATTR that's sent with a zero
value filehandle, and results in the server returning an error.
Instead, for the CLAIM_FH OPEN, take the filehandle that was used
in the PUTFH of the OPEN compound.

git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf
netfilter pull request 23-09-13
====================
The following patchset contains Netfilter fixes for net:
1) Do not permit to remove rules from chain binding, otherwise
double rule release is possible, triggering UaF. This rule
deletion support does not make sense and userspace does not use
this. Problem exists since the introduction of chain binding support.
2) rbtree GC worker only collects the elements that have expired.
This operation is not destructive, therefore, turn write into
read spinlock to avoid datapath contention due to GC worker run.
This was not fixed in the recent GC fix batch in the 6.5 cycle.
3) pipapo set backend performs sync GC, therefore, catchall elements
must use sync GC queue variant. This bug was introduced in the
6.5 cycle with the recent GC fixes.
4) Stop GC run if memory allocation fails in pipapo set backend,
otherwise access to NULL pointer to GC transaction object might
occur. This bug was introduced in the 6.5 cycle with the recent
GC fixes.
5) rhash GC run uses an iterator that might hit EAGAIN to rewind,
triggering double-collection of the same element. This bug was
introduced in the 6.5 cycle with the recent GC fixes.
6) Do not permit to remove elements in anonymous sets, this type of
sets are populated once and then bound to rules. This fix is
similar to the chain binding patch coming first in this batch.
API permits since the very beginning but it has no use case from
userspace.

net: Add Half Duplex support for ICSSG Driver
This series adds support for half duplex operation for ICSSG driver.
In order to support half-duplex operation at 10M and 100M link speeds, the
PHY collision detection signal (COL) should be routed to ICSSG GPIO pin
(PRGx_PRU0/1_GPI10) so that firmware can detect collision signal and apply
the CSMA/CD algorithm applicable for half duplex operation. A DT property,
"ti,half-duplex-capable" is introduced for this purpose in the first patch
of the series. If board has PHY COL pin conencted to PRGx_PRU1_GPIO10,
this DT property can be added to eth node of ICSSG, MII port to support
half duplex operation at that port.
Second patch of the series configures driver to support half-duplex
operation if the DT property "ti,half-duplex-capable" is enabled.
This series addresses comments on [v2]. This series is based on the latest
net-next/main. This series has no dependency.
Changes from v1 to v2:
*) Changed the description of "ti,half-duplex-capable" property as asked
by Rob and Andrew to avoid confusion between capable and enable.
Changes from v1 to v2:
*) Dropped the RFC tag.
*) Added RB tags of Andrew and Roger.

This patch adds support for half duplex operation at 10M and 100M link
speeds for AM654x/AM64x devices.
- Driver configures rand_seed, a random number, in DMEM HD_RAND_SEED_OFFSET
field, which will be used by firmware for Back off time calculation.
- Driver informs FW about half duplex link operation in DMEM
PORT_LINK_SPEED_OFFSET field by setting bit 7 for 10/100M HD.
Hence, the half duplex operation depends on board design the
"ti,half-duplex-capable" property has to be enabled for ICSS-G ports if HW
is capable to perform half duplex.

Alex reported that running ssh over IPv6 does not work with
Thunderbolt/USB4 networking driver. The reason for that is that driver
should call skb_is_gso() before calling skb_is_gso_v6(), and it should
not return false after calculates the checksum successfully. This probably
was a copy paste error from the original driver where it was done properly.

When a PTP ethernet raw frame with a size of more than 256 bytes followed
by a 0xff pattern is sent to __skb_flow_dissect, nhoff value calculation
is wrong. For example: hdr->message_length takes the wrong value (0xffff)
and it does not replicate real header length. In this case, 'nhoff' value
was overridden and the PTP header was badly dissected. This leads to a
kernel crash.
net/core: flow_dissector
net/core flow dissector nhoff = 0x0000000e
net/core flow dissector hdr->message_length = 0x0000ffff
net/core flow dissector nhoff = 0x0001000d (u16 overflow)

skb frag: 00000000: f7 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
Using the size of the ptp_header struct will allow the corrected
calculation of the nhoff value.
net/core flow dissector nhoff = 0x0000000e
net/core flow dissector nhoff = 0x00000030 (sizeof ptp_header)

We auto-negotiate most ports in the RTL8366RB driver, but
the CPU port is hard-coded to 1Gbit, full duplex, tx and
rx pause.
This isn't very nice. People may configure speed and
duplex differently in the device tree.
Actually respect the arguments passed to the function for
the CPU port, which get passed properly after Russell's
patch "net: dsa: realtek: add phylink_get_caps implementation"
After this the link is still set up properly.

The driver can now use PTP if enabled but fails to link built-in
if PTP is a loadable module:

Add the usual dependency to avoid this.

PTP block supports generating PPS output signal on GPIO pin. This patch
adds the support in the PTP PHC driver using standard periodic output
interface.
User can enable/disable/configure PPS by writing to the below sysfs entry
echo perout.index start.sec start.nsec period.sec period.nsec >
/sys/class/ptp/ptp0/period
Example to generate 50% duty cycle PPS signal:
echo 0 0 0 0 500000000 > /sys/class/ptp/ptp0/period

Eric Dumazet says:
====================
ipv6: round of data-races fixes
This series is inspired by one related syzbot report.
Many inet6_sk(sk) fields reads or writes are racy.
Move 1-bit fields to inet->inet_flags to provide
atomic safety. inet6_{test|set|clear|assign}_bit() helpers
could be changed later if we need to make room in inet_flags.
Also add missing READ_ONCE()/WRITE_ONCE() when
lockless readers need access to specific fields.
np->srcprefs will be handled separately to avoid merge conflicts
because a prior patch was posted for net tree.
