The PowerNV hotplug driver needs to be able to clear any frozen PE(s)
on the PHB after suprise removal of a downstream device.
Export the eeh_unfreeze_pe() symbol to allow implementation of this

The Microsemi Switchtec PM8533 PFX 48xG3 [11f8:8533] PCIe switch system
was observed to incorrectly assert the Presence Detect Set bit in its
capabilities when tested on a Raptor Computing Systems Blackbird system,
resulting in the hot insert path never attempting a rescan of the bus
and any downstream devices not being re-detected.
Work around this by additionally checking whether the PCIe data link is
active or not when performing presence detection on downstream switches'
ports, similar to the pciehp_hpc.c driver.

When the root of a nested PCIe bridge configuration is unplugged, the
pnv_php driver leaked the allocated IRQ resources for the child bridges'
hotplug event notifications, resulting in a panic.
Fix this by walking all child buses and deallocating all its IRQ resources
before calling pci_hp_remove_devices().
Also modify the lifetime of the workqueue at struct pnv_php_slot::wq so
that it is only destroyed in pnv_php_free_slot(), instead of
pnv_php_disable_irq(). This is required since pnv_php_disable_irq() will
now be called by workers triggered by hot unplug interrupts, so the
workqueue needs to stay allocated.

Zboot compressed kernel images are used for arm64 kernels on various
distros.
extract-vmlinux fails with those kernels because the wrapped image is
another PE. While this could be a bit confusing, the tools primary
purpose of unwrapping and decompressing the contained kernel image
makes it the obvious place for this functionality.
Add a 'file' check in check_vmlinux() that detects a contained PE
image before trying readelf. Recent (FILES_39, Jun/2020) file
implementations output something like:
"Linux kernel ARM64 boot executable Image, little-endian, 4K pages"
Which is also a stronger statement than readelf provides so drop that
part of the comment. At the same time this means that kernel images
which don't appear to contain a compressed image will be returned
rather than reporting an error. Which matches the behavior for
existing ELF files.
The extracted PE image can then be inspected, or used as would any
other kernel PE.

With arm64 64K page size, the following 4 subtests failed:
#97/25 dynptr/test_probe_read_user_dynptr:FAIL
#97/26 dynptr/test_probe_read_kernel_dynptr:FAIL
#97/27 dynptr/test_probe_read_user_str_dynptr:FAIL
#97/28 dynptr/test_probe_read_kernel_str_dynptr:FAIL
These failures are due to function bpf_dynptr_check_off_len() in
include/linux/bpf.h where there is a test
if (len > size || offset > size - len)
return -E2BIG;
With 64K page size, the 'offset' is greater than 'size - len',
which caused the test failure.
For 64KB page size, this patch increased the xdp buffer size from 5000 to
90000. The above 4 test failures are fixed as 'size' value is increased.
But it introduced two new failures:
#97/4 dynptr/test_dynptr_copy_xdp:FAIL
#97/12 dynptr/test_dynptr_memset_xdp_chunks:FAIL
These two failures will be addressed in subsequent patches.

KSZ8463 switch is a 3-port switch based from KSZ8863. Its major
difference from other KSZ SPI switches is its register access is not a
simple continual 8-bit transfer with automatic address increase but uses
a byte-enable mechanism specifying 8-bit, 16-bit, or 32-bit access. Its
registers are also defined in 16-bit format because it shares a design
with a MAC controller using 16-bit access. As a result some common
register accesses need to be re-arranged.
This patch adds the basic structure for using KSZ8463. It cannot use the
same regmap table for other KSZ switches as it interprets the 16-bit
value as little-endian and its SPI commands are different.
KSZ8463 uses a byte-enable mechanism to specify 8-bit, 16-bit, and 32-bit
access. The register is first shifted right by 2 then left by 4. Extra
4 bits are added. If the access is 8-bit one of the 4 bits is set. If
the access is 16-bit two of the 4 bits are set. If the access is 32-bit
all 4 bits are set. The SPI command for read or write is then added.
Because of this register transformation separate SPI read and write
functions are provided for KSZ8463.
KSZ8463's internal PHYs use standard PHY register definitions so there is
no need to remap things. However, the hardware has a bug that the high
word and low word of the PHY id are swapped. In addition the port
registers are arranged differently so KSZ8463 has its own mapping for
port registers and PHY registers. Therefore the PORT_CTRL_ADDR macro is
replaced with the get_port_addr helper function.

====================
pull-request: can-next 2025-07-25
The first patch is by Khaled Elnaggar and converts the janz-ican3
driver's fwinfo_show() to sysfs_emit().
Vincent Mailhol contributes 3 patches that first fix a warning in the
ti_hecc driver and then add missing COMPILE_TEST more compile
coverage to the ti_hecc and tscan1 driver.
Randy Dunlap's patch let's the tscan1 driver depend on PC104.
A patch by Luis Felipe Hernandez fixes a kernel-doc error in the
ctucanfd driver.
Jimmy Assarsson contributes 10 patches for the kvaser_pciefd and 11
for the kvaser_usb driver. Both series simplify the identification of
physical the CAN interfaces and add devlink support to get information
about the running firmware.

libie: commonize adminq structure
Michal Swiatkowski says:
It is a prework to allow reusing some specific Intel code (eq. fwlog).
Move common *_aq_desc structure to libie header and changing
it in ice, ixgbe, i40e and iavf.
Only generic adminq commands can be easily moved to common header, as
rest is slightly different. Format remains the same. It will be better
to correctly move it when it will be needed to commonize other part of
the code.
Move *_aq_str() to new libie module (libie_adminq) and use it across
drivers. The functions are exactly the same in each driver. Some more
adminq helpers/functions can be moved to libie_adminq when needed.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
i40e: use libie_aq_str
iavf: use libie_aq_str
ice: use libie_aq_str
libie: add adminq helper for converting err to str
iavf: use libie adminq descriptors
i40e: use libie adminq descriptors
ixgbe: use libie adminq descriptors
ice, libie: move generic adminq descriptors to lib

Currently, packets dropped by pfifo_fast due to queue overflow are
marked with a generic SKB_DROP_REASON_QDISC_DROP in __dev_xmit_skb().
This patch adds explicit drop reason SKB_DROP_REASON_QDISC_OVERLIMIT
for queue-full cases, providing better distinction from other qdisc drops.

This patch introduces is_bnode_offset_valid() method that checks
the requested offset value. Also, it introduces
check_and_correct_requested_length() method that checks and
correct the requested length (if it is necessary). These methods
are used in hfs_bnode_read(), hfs_bnode_write(), hfs_bnode_clear(),
hfs_bnode_copy(), and hfs_bnode_move() with the goal to prevent
the access out of allocated memory and triggering the crash.

====================
net: Add sockaddr_inet unified address structure
Repeating patch 1, as it has the rationale:
There are cases in networking (e.g. wireguard, sctp) where a union is
used to provide coverage for either IPv4 or IPv6 network addresses,
and they include an embedded "struct sockaddr" as well (for "sa_family"
and raw "sa_data" access). The current struct sockaddr contains a
flexible array, which means these unions should not be further embedded
in other structs because they do not technically have a fixed size (and
are generating warnings for the coming -Wflexible-array-not-at-end flag
addition). But the future changes to make struct sockaddr a fixed size
(i.e. with a 14 byte sa_data member) make the "sa_data" uses with an IPv6
address a potential place for the compiler to get upset about object size
mismatches. Therefore, we need a sockaddr that cleanly provides both an
sa_family member and an appropriately fixed-sized sa_data member that does
not bloat member usage via the potential alternative of sockaddr_storage
to cover both IPv4 and IPv6, to avoid unseemly churn in the affected code
bases.
Introduce sockaddr_inet as a unified structure for holding both IPv4 and
IPv6 addresses (i.e. large enough to accommodate sockaddr_in6).
The structure is defined in linux/in6.h since its max size is sized
based on sockaddr_in6 and provides a more specific alternative to the
generic sockaddr_storage for IPv4 with IPv6 address family handling.
The "sa_family" member doesn't use the sa_family_t type to avoid needing
layer violating header inclusions.
Also includes the replacements for wireguard and sctp.

As part of the removal of the variably-sized sockaddr for kernel
internals, replace struct sockaddr with sockaddr_inet in the sctp_addr
union.
No binary changes; the union size remains unchanged due to sockaddr_inet
matching the size of sockaddr_in6.
