"A few more device specific fixes plus one trivial quirk.
There's a couple of patches for Tegra which avoid some fairly

actually seen in production, plus a fix for the i.MX driver to
propagate errors properly when setting up the hardware.
We also have a trivial patch marking the sun4i driver as being

The ICSS IEP driver tracks perout and pps enable state with flags.
Currently when disabling pps and perout signals during icss_iep_exit(),
results in NULL pointer dereference for perout.
To fix the null pointer dereference issue, the icss_iep_perout_enable_hw
function can be modified to directly clear the IEP CMP registers when
disabling PPS or PEROUT, without referencing the ptp_perout_request
structure, as its contents are irrelevant in this case.

emac_xmit_xdp_frame()
There is an error check inside emac_xmit_xdp_frame() function which
is called when the driver wants to transmit XDP frame, to check if
the allocated tx descriptor is NULL, if true to exit and return
ICSSG_XDP_CONSUMED implying failure in transmission.
In this case trying to free a descriptor which is NULL will result
in kernel crash due to NULL pointer dereference. Fix this error handling
and increase netdev tx_dropped stats in the caller of this function
if the function returns ICSSG_XDP_CONSUMED.

During network interface initialization, the NIC driver needs to register
its Rx queue with the XDP, to ensure the incoming XDP buffer carries a
pointer reference to this info and is stored inside xdp_rxq_info.
While this struct isn't tied to XDP prog, if there are any changes in
Rx queue, the NIC driver needs to stop the Rx queue by unregistering
with XDP before purging and reallocating memory. Drop page_pool destroy
during Rx channel reset as this is already handled by XDP during
xdp_rxq_info_unreg (Rx queue unregister), failing to do will cause the
following warning:

Russell King reports that on the ZII dev rev B, deleting a bridge VLAN
from a user port fails with -ENOENT:
https://lore.kernel.org/netdev/Z_lQXNP0s5-IiJzd@shell.armlinux.org.uk/
This comes from mv88e6xxx_port_vlan_leave() -> mv88e6xxx_mst_put(),
which tries to find an MST entry in &chip->msts associated with the SID,
but fails and returns -ENOENT as such.
But we know that this chip does not support MST at all, so that is not
surprising. The question is why does the guard in mv88e6xxx_mst_put()
not exit early:
if (!sid)
return 0;
And the answer seems to be simple: the sid comes from vlan.sid which
supposedly was previously populated by mv88e6xxx_vtu_get().
But some chip->info->ops->vtu_getnext() implementations do not populate
vlan.sid, for example see mv88e6185_g1_vtu_getnext(). In that case,
later in mv88e6xxx_port_vlan_leave() we are using a garbage sid which is
just residual stack memory.
Testing for sid == 0 covers all cases of a non-bridge VLAN or a bridge
VLAN mapped to the default MSTI. For some chips, SID 0 is valid and
installed by mv88e6xxx_stu_setup(). A chip which does not support the
STU would implicitly only support mapping all VLANs to the default MSTI,
so although SID 0 is not valid, it would be sufficient, if we were to
zero-initialize the vlan structure, to fix the bug, due to the
coincidence that a test for vlan.sid == 0 already exists and leads to
the same (correct) behavior.
Another option which would be sufficient would be to add a test for
mv88e6xxx_has_stu() inside mv88e6xxx_mst_put(), symmetric to the one
which already exists in mv88e6xxx_mst_get(). But that placement means
the caller will have to dereference vlan.sid, which means it will access
uninitialized memory, which is not nice even if it ignores it later.
So we end up making both modifications, in order to not rely just on the
sid == 0 coincidence, but also to avoid having uninitialized structure
fields which might get temporarily accessed.

Russell King reports that a system with mv88e6xxx dereferences a NULL
pointer when unbinding this driver:
https://lore.kernel.org/netdev/Z_lRkMlTJ1KQ0kVX@shell.armlinux.org.uk/
The crash seems to be in devlink_region_destroy(), which is not NULL
tolerant but is given a NULL devlink global region pointer.
At least on some chips, some devlink regions are conditionally registered
since the blamed commit, see mv88e6xxx_setup_devlink_regions_global():
if (cond && !cond(chip))
continue;
These are MV88E6XXX_REGION_STU and MV88E6XXX_REGION_PVT. If the chip
does not have an STU or PVT, it should crash like this.
To fix the issue, avoid unregistering those regions which are NULL, i.e.
were skipped at mv88e6xxx_setup_devlink_regions_global() time.

When txgbe_sw_init() is called, memory is allocated for wx->rss_key
in wx_init_rss_key(). However, in txgbe_probe() function, the subsequent
error paths after txgbe_sw_init() don't free the rss_key. Fix that by
freeing it in error path along with wx->mac_table.
Also change the label to which execution jumps when txgbe_sw_init()
fails, because otherwise, it could lead to a double free for rss_key,
when the mac_table allocation fails in wx_sw_init().

In the for loop used to allocate the loc_array and bmap for each port, a
memory leak is possible when the allocation for loc_array succeeds,
but the allocation for bmap fails. This is because when the control flow
goes to the label free_eth_finfo, only the allocations starting from
(i-1)th iteration are freed.
Fix that by freeing the loc_array in the bmap allocation error path.

string instead of copying from .rodata into stack and then into the skb.
We can go directly from .rodata to the skb.
This also works around a Clang bug (that has since been fixed[1]).

When filling the taskfile result for a successful NCQ command, we use
the SDB FIS from the FIS Receive Area, see e.g. ahci_qc_ncq_fill_rtf().
However, the SDB FIS only has fields STATUS and ERROR.
For a successful NCQ command that has sense data, we will have a
successful sense data descriptor, in the Sense Data for Successful NCQ
Commands log.
Since we have access to additional taskfile result fields, fill in these
additional fields in qc->result_tf.
This matches how for failing/aborted NCQ commands, we will use e.g.
ahci_qc_fill_rtf() to fill in some fields, but then for the command that
actually caused the NCQ error, we will use ata_eh_read_log_10h(), which
provides additional fields, saving additional fields/overriding the
qc->result_tf that was fetched using ahci_qc_fill_rtf().

The ACPI byte code inside the ACPI control method responsible for
handling the WMI method calls uses a global buffer for constructing
the return value, yet the ACPI control method itself is not marked
as "Serialized".
This means that calling WMI methods on this WMI device is not
thread-safe, as concurrent WMI method calls will corrupt the global
buffer.
Fix this by serializing the WMI method calls using a mutex.

This reverts commit 479380efe1625e251008d24b2810283db60d6fcd.
The reset_method attribute on a PCI device is only intended to manage the
availability of function scoped resets for a device. It was never intended
to restrict resets targeting the bus or slot.
In introducing a restriction that each device must support function level
reset by testing pci_reset_supported(), we essentially create a catch-22,
that a device must have a function scope reset in order to support bus/slot
reset, when we use bus/slot reset to effect a reset of a device that does
not support a function scoped reset, especially multi-function devices.
This breaks the majority of uses cases where vfio-pci uses bus/slot resets
to manage multifunction devices that do not support function scoped resets.

On malfunctioning hardware, timeout error messages can appear thousands
of times, creating unnecessary system pressure and log bloat. This patch
makes two improvements:
1. Replace dev_err() with dev_err_ratelimited() to prevent log flooding
when hardware errors persist
2. Remove the redundant timeout value parameter from the error message,
as 'ret' is always zero in this error path
These changes reduce logging overhead while maintaining necessary error
reporting for debugging purposes.

====================
igc: Fix PTM timeout
Christopher S M Hall says:
There have been sporadic reports of PTM timeouts using i225/i226 devices
These timeouts have been root caused to:
1) Manipulating the PTM status register while PTM is enabled
and triggered
2) The hardware retrying too quickly when an inappropriate response
is received from the upstream device
The issue can be reproduced with the following:
$ sudo phc2sys -R 1000 -O 0 -i tsn0 -m
Note: 1000 Hz (-R 1000) is unrealistically large, but provides a way to
quickly reproduce the issue.
PHC2SYS exits with:
"ioctl PTP_OFFSET_PRECISE: Connection timed out" when the PTM transaction
fails
The first patch in this series also resolves an issue reported by Corinna
Vinschen relating to kdump:
This patch also fixes a hang in igc_probe() when loading the igc
driver in the kdump kernel on systems supporting PTM.
The igc driver running in the base kernel enables PTM trigger in
igc_probe(). Therefore the driver is always in PTM trigger mode,
except in brief periods when manually triggering a PTM cycle.
When a crash occurs, the NIC is reset while PTM trigger is enabled.
Due to a hardware problem, the NIC is subsequently in a bad busmaster
state and doesn't handle register reads/writes. When running
igc_probe() in the kdump kernel, the first register access to a NIC
register hangs driver probing and ultimately breaks kdump.
With this patch, igc has PTM trigger disabled most of the time,
and the trigger is only enabled for very brief (10 - 100 us) periods
when manually triggering a PTM cycle. Chances that a crash occurs
during a PTM trigger are not zero, but extremly reduced.
* '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
igc: add lock preventing multiple simultaneous PTM transactions
igc: cleanup PTP module if probe fails
igc: handle the IGC_PTP_ENABLED flag correctly
igc: move ktime snapshot into PTM retry loop
igc: increase wait time before retrying PTM

Typically pdev->irq is consistent with whether the device itself
supports INTx, where device support is reported via the PIN register.
Therefore the PIN register is often already zero if pdev->irq is zero.
Recently virtualization of the PIN register was expanded to include
the case where the device supports INTx but the platform does not
route the interrupt. This is reported by a value of IRQ_NOTCONNECTED
on some architectures. Other architectures just report zero for
pdev->irq.
We already disallow INTx setup if pdev->irq is zero, therefore add
this to the PIN register virtualization criteria so that a consistent
view is provided to userspace through virtualized config space and
ioctls.

The MAC hardware supports receiving two types of
pause frames from link partner.
One is a pause frame with a destination address
of 01:80:C2:00:00:01.
The other is a pause frame whose destination address
is the address of the hibmcge driver.
01:80:C2:00:00:01 is supported by default.
In .ndo_set_mac_address(), the hibmcge driver calls
.hbg_hw_set_rx_pause_mac_addr() to set its mac address as the
destination address of the rx puase frame.
Therefore, pause frames with two types of MAC addresses can be received.
Currently, the rx pause addr does not restored after reset.
As a result, pause frames whose destination address is
the hibmcge driver address cannot be correctly received.
This patch restores the configuration by calling
.hbg_hw_set_rx_pause_mac_addr() after reset is complete.
