Fix by allocating the new label before taking vol_ni->mrec_lock and
updating any on-disk metadata, so an -ENOMEM from kstrdup() leaves
both the in-memory and on-disk labels untouched and consistent. On
success the preallocated copy replaces the old vol->volume_label.

net: dsa: microchip: Remove one indirection layer
This series follows the discussions we had on a previous series that
aimed to add PTP support for the KSZ8463 (cf [1]).
The KSZ driver got way too convoluted over time because it uses a common
framework to handle more than 20 switches split in 5 families (see below
table)
A unique struct dsa_switch_ops is used by all the switches. Next to it,
each switch family has its own struct ksz_dev_ops with family-specific
callbacks. So the dsa_switch_ops operations handle the specificities of
each family through these ksz_dev_ops callbacks and/or conditional
branches based on the chip ID.
Vladimir initiated a rework of the driver ([2]) which I carried on. On
top of the rework I added PTP and periodic output support for the
KSZ8463 (which was my first goal). There are more than 60 patches for
all this so this series will be followed by several others and if you
want to see the full picture we can check my github ([3]).
This first series aims to split the unique struct dsa_switch_ops into
5 so each switch family will be able to implement its own set of DSA
operations.
I haven't finished yet to group all the patches into meaningful series
but here is more or less what I plan to do next:
- A series will remove from the struct ksz_dev_ops the callbacks
that have an equivalent in dsa_switch_ops to remove one level of
indirection.
- A series will split again some operations to get rid of the
if (is_kszXYZ) branches.
- Maybe a fourth one will be needed to completely move out of
ksz_common.c everything that isn't truly common to all the switches
- A series will add PTP support for the KSZ8463
- A final series will add periodic output support for the KSZ8463
All the KSZ switches use the same ksz_connect_tag_protocol while they
don't support all the KSZ tag protocols. So if, for some reason, a given
switch tries to connect another KSZ tag protocol, it won't fail.
Split the common ksz_connect_tag_protocol() into switch-specific
operations. This way, each switch will only accept to connect the tag
protocol it supports.
Remove the no longer used common operation.

net: dsa: microchip: split ksz_get_tag_protocol()
All the switch families use a common function to implement
.get_tag_protocol(). This function then returns the relevant protocol
depending on the chip ID.
Make the protocol to dsa_switch_ops association a little bit more
obvious by having separate implementations.
Change made by manually checking which chip id has which dsa_switch_ops
assigned to it, then filtering the common ksz_get_tag_protocol() for
just those chip IDs pertaining to it.
As an important benefit, we no longer have that weird-looking
DSA_TAG_PROTO_NONE fallback which was never actually returned.

structure.

net: dsa: microchip: ensure each ksz_dev_ops has its own dsa_switch_ops
Currently we have a single dsa_switch_ops for 4 very distinct families
of switches, and many dsa_switch_ops methods are simply a dispatches
through ksz_dev_ops. That creates an avoidable level of indirection.
As a preparation for removing that indirection layer, create a separate
dsa_switch_ops structure wherever we have a ksz_dev_ops. These
structures are not yet used - ksz_switch_ops from ksz_common.c still is.
However, this reduces the noise from subsequent changes.
All new dsa_switch_ops are exact copies of ksz_switch_ops. But we need
to export function prototypes from ksz_common.c so that they are
callable from individual drivers.
Note that "individual drivers" are not actual separate kernel modules.
All of ksz8.c, ksz9477.c and lan937x_main.c are part of the same
ksz_switch.ko. Only the "register interface" drivers are different
modules (ksz9477_i2c.o for I2C, ksz_spi.o for SPI, ksz8863_smi.o for
MDIO). So we don't need to export any symbol.

net/mlx5: ICM page management in VHCA_ID mode
This series adds driver support for the VHCA_ID page management mode.
When firmware and driver support this mode, ICM (Interconnect Context
Memory) page management uses the device vhca_id as the function
identifier in MANAGE_PAGES, QUERY_PAGES, and page request events instead
of the legacy function_id + ec_function pair.
Background
Firmware can operate page management in two modes:
FUNC_ID mode (current): Function identity is (function_id, ec_function).
This remains the default and is used for boot pages and when the new
mode capability is not set.
VHCA_ID mode (new): Function identity is vhca_id only; ec_function is
ignored. This aligns page management with the vhca_id-based model used
by other firmware commands and simplifies identification on SmartNIC and
multi-function setups.

net/mlx5: Add VHCA_ID page management mode support
Add support for VHCA_ID-based page management mode. When the device
firmware advertises the icm_mng_function_id_mode capability with
MLX5_ID_MODE_FUNCTION_VHCA_ID, page management operations between the
driver and firmware may use vhca_id instead of function_id as the
effective function identifier, and the ec_function field is ignored.
Update page management commands to conditionally set ec_function field
only in FUNC_ID mode. Boot page allocation always uses FUNC_ID mode
semantics for backward compatibility, as the capability bit is only
available after set_hca_cap(). If after set_hca_cap() VHCA_ID mode was
set, modify the tracking of the boot pages in page_root_xa to use
vhca_id too.
Add mlx5_esw_vhca_id_to_func_type() to resolve the function type in
VHCA_ID mode, enabling per-type debugfs counters. Use a dedicated
vhca_type_map xarray, to provide lockless lookup. Store the resolved
type on each fw_page at allocation time so reclaim and release paths
read it directly without any lookup.

net/mlx5: Relax capability check for eswitch query paths
Several eswitch functions that only query other functions' HCA
capabilities or read cached vport state are guarded by the
vhca_resource_manager capability. This capability is required for
set_hca_cap operations but query_hca_cap of other functions only
requires the vport_group_manager capability.
Relax the capability check from vhca_resource_manager to
vport_group_manager in the following query-only paths:
- mlx5_esw_vport_caps_get() - queries other function general caps
- esw_ipsec_vf_query_generic() - queries other function ipsec cap

Netfilter fixes for net
The following batch contains Netfilter fixes for net:
1) Allow initial x_tables table replacement without emitting an audit
log message. Delay the register message until after hooks are wired up
to avoid unnecessary unregister logs during error unwinding.
2) Fix a NULL dereference by allocating hook ops before adding the
table to the per-netns list. Use `synchronize_rcu()` during error
unwinding to ensure the table stops processing packets before
teardown. Defer audit log register message until all operations
succeed.
3) Refactor xtables to use a single `xt_unregister_table_pre_exit`
function. Eliminate code duplication by centralizing table
unregistration logic within the xtables core. ebtables cannot be
changed due to incompatibility.
4) Unregister xtables templates before module removal. This prevents
a race condition where userspace instantiates a new table after the
pernet unreg removed the current table.
5) Add `xtables_unregister_table_exit` to fully unregister netfilter
tables during module removal. Unlink the table from dying lists,
then free hook operations.
6) Implement a two-stage removal scheme for ebtables following the
x_tables pattern. Assign table->ops while holding the ebt mutex to
prevent exposing partially-filled structures.
7) Fix ebtables module initialization race. Register the template last
in table initialization functions. Prevent table instantiation before
pernet operations are available.
8) Fix a race condition in x_tables module initialization. Ensure
pernet ops are fully set up before exposing the table to userspace.

drbd: replace genl_magic with explicit netlink serialization
Replace the genl_magic multi-include macro system with explicit
serialization and parsing.
The *_gen files were initially produced from a YNL spec via a
customized ynl-gen-c, but the DRBD netlink family is effectively
frozen, so the generator is kept unmodified.
All new functionality will land in a separate, properly-designed
family.
Carry the resulting code as ordinary in-tree source rather than
landing the spec and generator changes that produced it.
The bulk of the changes are mechanical renames to fit the YNL naming
conventions:
- Handler functions: drbd_adm_* -> drbd_nl_*_doit/dumpit
- GENL_MAGIC_VERSION -> DRBD_FAMILY_VERSION
- GENL_MAGIC_FAMILY_HDRSZ -> sizeof(struct drbd_genlmsghdr)
- drbd_genl_family -> drbd_nl_family
- Attribute IDs: T_* -> DRBD_A_*
Remove the nested_attr_tb static global buffer and move to a per-call
allocation approach: each deserialization manages its own nested
attribute table. This will be needed anyway when we eventually move
to parallel_ops, and it's actually simpler this way, so make the
move now.
Replace the functionality of the "sensitive" flag: this was only used
by a single field (shared_secret); open-code redaction logic for that
locally.
Also replace the "invariant" flag: this only had a couple of users,
and those basically never change. Hard code the check directly inline.
The genl_family struct itself is defined manually in drbd_nl.c.
Also replace a couple of drbd-specific wrappers (nla_put_u64_0pad,
drbd_nla_find_nested) with standard kernel functions while we're at
it.
Finally, completely remove the genl_magic system; DRBD was its only
user.
drbd.h and drbd_limits.h contain only type definitions, enums, and
constants shared between kernel and userspace. These should be part of
UAPI.
Split the genl_api header into two: the genlmsghdr and the enums are
UAPI, the rest stays there for now (it will be removed by one of the
next commits in this series).
drbd_config.h is clearly DRBD-internal, so move it there.

drop the socket lock inside sctp_wait_for_sndbuf().
While the lock is dropped, another thread can SCTP_SOCKOPT_PEELOFF the
association cached in @tmp, migrating it to a new endpoint via
sctp_sock_migrate() (list_del_init() + list_add_tail() to
newep->asocs), and optionally close the new socket which frees the
association via kfree_rcu(). The cached @tmp can also be freed by a
network ABORT for that association, processed in softirq while the
lock is dropped.
sctp_wait_for_sndbuf() revalidates @asoc (the current entry) on re-lock
via the "sk != asoc->base.sk" and "asoc->base.dead" checks, but nothing
revalidates @tmp. After a successful return, the iterator advances to
the stale @tmp, yielding either a use-after-free (if the peeled socket
was closed) or a list-walk onto the new endpoint's list head (type
confusion of &newep->asocs as a struct sctp_association *).
Both are reachable from CapEff=0; the type-confusion path gives
controlled indirect call via the outqueue.sched->init_sid pointer.
Fix by re-deriving @tmp from @asoc after sctp_sendmsg_to_asoc()
returns. @asoc is known to still be on ep->asocs at that point: the
only callers that list_del an association from ep->asocs are
sctp_association_free() (which sets asoc->base.dead) and
sctp_assoc_migrate() (which changes asoc->base.sk), and
sctp_wait_for_sndbuf() checks both under the lock before any
successful return; a tripped check propagates as err < 0 and the loop
bails before the re-derive.
The SCTP_ABORT path in sctp_sendmsg_check_sflags() returns 0 and the
loop hits 'continue' before sctp_sendmsg_to_asoc() is ever called, so
the @tmp cached by list_for_each_entry_safe() still covers the
lock-held free that ba59fb027307 ("sctp: walk the list of asoc
safely") was added for.

Ido Schimmel says:
====================
net: Fix protodown with macvlan
When protodown is enabled on a macvlan, two bugs cause the macvlan to
incorrectly gain carrier:
1. Toggling the lower device's carrier while protodown is enabled on the
macvlan causes the macvlan to gain carrier, effectively bypassing the
protodown mechanism.
2. Toggling protodown on and then off on the macvlan while the lower
device has no carrier causes the macvlan to gain carrier, since
netif_change_proto_down() unconditionally turns the carrier on.
Patch #1 is a preparation.
Patch #2 solves the first problem by making netif_carrier_on() return
early when protodown is on.
Patch #3 solves the second problem by only calling netif_carrier_on()
when protodown is turned off if there is no linked net device or if the
linked net device has a carrier.
Patch #4 adds a selftest covering both bugs and the basic protodown
functionality.
Targeting at net-next since these are not regressions (i.e., never
worked).
Note that while these changes are in the core, they should only affect
macvlan as protodown is only supported by macvlan and vxlan and only
the former has a linked net device.

results in DOWN operational state and clearing it restores UP.
2. Same as the previous test case, but with vxlan.
3. Protodown reasons: Verify that protodown cannot be cleared while
there are active protodown reasons, but can be cleared once all

macvlan to gain carrier.
5. Protodown with lower device down: Verify that toggling protodown
while the lower device has no carrier does not cause the macvlan to

net: Do not unconditionally turn on carrier when turning off protodown
The protodown functionality allows user space to turn off the carrier of
a net device:
# ip link add name dummy1 up type dummy
# ip link add name macvlan1 up link dummy1 type macvlan mode bridge
# ip link set dev macvlan1 protodown on
$ ip -br link show dev macvlan1
macvlan1@dummy1 DOWN 0a:5c:a3:05:c7:86 <NO-CARRIER,BROADCAST,MULTICAST,UP>
When protodown is turned off, the core unconditionally turns on the
carrier of the net device:
# ip link set dev macvlan1 protodown off
$ ip -br link show dev macvlan1
macvlan1@dummy1 UP 0a:5c:a3:05:c7:86 <BROADCAST,MULTICAST,UP,LOWER_UP>
This is wrong as it means that a macvlan can end up with a carrier when
its lower device does not have a carrier:
# ip link set dev dummy1 carrier off
$ ip -br link show dev macvlan1
macvlan1@dummy1 LOWERLAYERDOWN 0a:5c:a3:05:c7:86 <NO-CARRIER,BROADCAST,MULTICAST,UP>
# ip link set dev macvlan1 protodown on
# ip link set dev macvlan1 protodown off
$ ip -br link show dev macvlan1
macvlan1@dummy1 UP 0a:5c:a3:05:c7:86 <BROADCAST,MULTICAST,UP,LOWER_UP>
Solve this by resolving the linked net device and if one exists, inherit
its carrier state when protodown is turned off. Otherwise, if no linked
net device exists, as before, simply turn on the carrier.
Resolve the linked net device using a new helper and have it return the
device itself (in a similar fashion to dev_get_iflink()) if the device
does not implement both ndo_get_iflink() and get_link_net(). If the
latter is not implemented, it is unclear in which network namespace we
should look up the linked net device. Currently, this helper is only
used for net devices that support protodown (macvlan and vxlan) and for
both it returns the correct result.

relied on by anyone. In fact, it is a problem for applications like FRR
that use protodown with macvlan on top of a bridge as part of Virtual

Keep PHY link during WoL sleep cycle
First we divide the init/deinit path to allow for a partial init/deinit

the same time.
Then we modify the suspend and resume path to allow for a partial bring
down and bring up. This allow us to keep the PHY link up and to resume
network traffic much quicker. Note we only do this when WoL is enabled
since the PHY is already powered. In the non-WoL case we want to follow

To prepare for a partial bring up of the interface during resume,
we break apart the bcmasp_netif_init() function into smaller chunks
that can be called as necessary. Also consolidate some functions that
do not need to be standalone.
hdr is declared as struct iommufd_vevent_header *, so sizeof(hdr)
evaluates to the size of the pointer. Surrounding code uses
sizeof(*hdr) consistently:
struct iommufd_vevent_header is currently 8 bytes (two __u32 fields,
flags and sequence), so on 64-bit (sizeof(void *) == 8) the two
expressions happen to be equal and the check works as intended.
On 32-bit (sizeof(void *) == 4) the check under-counts the header by
4 bytes: a vEVENT whose data_len causes 8 + cur->data_len to exceed
count - done while 4 + cur->data_len does not will pass the check,
then the loop will copy_to_user 8 bytes of header followed by data_len
bytes of payload, writing past the user-supplied buffer.
It is also a latent bug for any future expansion of struct
iommufd_vevent_header beyond sizeof(void *) on 64-bit; the check
should not depend on the type happening to match the host pointer
width.
Use sizeof(*hdr) to match the rest of the function and the actual
amount that will be copied.

We cycle through the number of available CSID ports and test this value
against the vc_en bitmask.
We then use the passed value both as an index to the port configuration
macros and as a virtual channel index.
This is a very broken pattern. Reviewing the initial introduction of VC
support it states that you can only map one CSID to one VFE. This is true
however each CSID has multiple sources which can sink inside of the VFE -
for example there is a "pixel" path for bayer stats which sources @
CSID(x):3 and sinks on VFE(x):pix.
That is CSID port # 3 should drive VFE port #3. With our current setup only
a sensor which drives virtual channel number #3 could possibly enable that
setup.
This is deeply wrong the virtual channel has no relevance to hooking CSID
to VFE, a fact that is proven after this patch is applied allowing
RDI0,RDI1 and RDI2 to function with VC0 whereas before only RDI1 worked.
Another way the current model breaks is the DT field. A sensor driving
different data-types on the same VC would not be able to separate the VC:DT
pair to separate RDI outputs, thus breaking another feature of VCs in the
MIPI data-stream.
Default the VC back to zero. A follow on series will implement subdev
streams to actually enable VCs without breaking CSID source to VFE sink.

Different RAW Bayer packing schemes impose different BPL alignment

media: uvcvideo: Fix buffer sequence in frame gaps
In UVC, the FID flips with every frame. For every FID flip, we increase
the stream sequence number.
Now, if a FID flips multiple times and there is no data transferred between
the flips, the buffer sequence number will be set to the value of the
stream sequence number after the first flip.
Userspace uses the buffer sequence number to determine if there have been
missing frames. With the current behaviour, userspace will think that the
gap is in the wrong location.
This patch modifies uvc_video_decode_start() to provide the correct buffer
sequence number and timestamp.

Fix this issue by moving the new frame detection logic earlier in

This also has some nice side affects:
- The error status from the new packet will no longer get propagated

Matt Volrath fixes two issues with the i40e driver probe routine, ensuring
that PTP is properly cleaned up if the probe fails.
Emil corrects the initialization of the read_dev_clk_lock spinlock in
idpf_ptp_init, ensuring it is initialized prior to when the
ptp_schedule_worker() is called.
Greg KH fixes a double free and use-after free in the idpf auxiliary device
error paths.
Marcin fixes ice_set_rss_hfunc() to use the correct q_opt_flags field,
correcting the assignment and preventing submission of invalid data to the
firmware.
Bart corrects the locking in ice_dcb_rebuild(), ensuring that the tc_mutex
is held over the entire operation.
Ivan fixes the rclk pin state get for E810 devices, ensuring the index is
properly offset by the base_rclk_idx value. This ensures that the correct
pin index is used to look up recovered clock state. He additionally adds
bounds checking to prevent attempting to access pins outside of the pin
state array.
Ivan also moves the CGU register macros to the top of ice_dpll.h, inside
the header guard to avoid duplicate macro definitions should the ice_dpll.h
header is included multiple times.

ice_set_rss_hfunc() performs a VSI update, in which it sets hashing
function, leaving other VSI options unchanged. However, ::q_opt_flags is
mistakenly set to the value of another field, instead of its original
value, probably due to a typo. What happens next is hardware-dependent:
On E810, only the first bit is meaningful (see

state than before VSI update.
On E830, some of the remaining bits are not reserved. Setting them

because of invalid settings, or worse - succeed.

When auxiliary_device_add() fails in idpf_plug_vport_aux_dev() or
idpf_plug_core_aux_dev(), the err_aux_dev_add label calls
auxiliary_device_uninit() and falls through to err_aux_dev_init. The
uninit call will trigger put_device(), which invokes the release
callback (idpf_vport_adev_release / idpf_core_adev_release) that frees
iadev. The fall-through then reads adev->id from the freed iadev for
ida_free() and double-frees iadev with kfree().
Free the IDA slot and clear the back-pointer before uninit, while adev
is still valid, then return immediately.

ethtool on this phy device always reports "MDI-X: Unknown" and doesn't
support forcing it to on or off.
This patch adds support for reading/forcing MDI-X mode from ethtool
properly.
Add three macros for declaring static binary attributes for PCI resource
files:
- pci_dev_resource_io_attr(), for I/O BAR resources (read/write)
- pci_dev_resource_uc_attr(), for memory BAR resources (mmap uncached)
- pci_dev_resource_wc_attr(), for write-combine resources (mmap WC)
Each macro only sets the callbacks its resource type needs. The I/O macro
conditionally includes mmap support via __PCI_RESOURCE_IO_MMAP_ATTRS on
architectures where arch_can_pci_mmap_io() is true at compile time (such as
PowerPC, SPARC, and Xtensa).
PCI/sysfs: Add CAP_SYS_ADMIN check to __resource_resize_store()
Currently, the __resource_resize_store() allows writing to the
resourceN_resize sysfs attribute to change a BAR's size without checking
for capabilities, currently relying only on the file access check.
Resizing a BAR modifies PCI device configuration and can disrupt active
drivers. After the upcoming conversion to static attributes, it will also
trigger resource file updates via sysfs_update_groups().
Add a CAP_SYS_ADMIN check to prevent unprivileged users from performing BAR
resize operations.

PCI/sysfs: Split pci_llseek_resource() for device and legacy attributes
Both legacy and resource attributes set .f_mapping = iomem_get_mapping, so
the default generic_file_llseek() would consult iomem_inode for the file
size, which knows nothing about the attribute. That is why custom llseek
callbacks exist.
Currently, the legacy and resource attributes have .size set at creation
time, as such, using the attr->size is sufficient. However, the upcoming
static resource attributes will have .size == 0 set, since they are const,
and the .bin_size() callback will be used to provide the real size to
kernfs instead.
The legacy attributes operate on a struct pci_bus, not struct pci_dev, so
calling to_pci_dev() on them would be invalid.
Thus, split pci_llseek_resource() into two functions:
- pci_llseek_resource(), which derives the file size from the BAR using
pci_resource_len().
- pci_llseek_resource_legacy(), which uses attr->size directly.
Update the dynamic legacy attribute creation to use the new
pci_llseek_resource_legacy() callback.
The original pci_llseek_resource() was added in commit 24de09c16f97 ("PCI:

net: shaper: Reject reparenting of existing nodes
When an existing node-scope shaper is moved to a different parent
via the group operation, the framework fails to update the leaves
count on both the old and new parent shapers. Only newly created
nodes (handle.id == NET_SHAPER_ID_UNSPEC) trigger the parent
leaves increment at line 1039.
This causes the parent's leaves counter to diverge from the
actual number of children in the xarray. When the node is later
deleted, pre_del_node() allocates an array sized by the stale
leaves count, but the xarray iteration finds more children than
expected, hitting the WARN_ON_ONCE guard and returning -EINVAL.
Rather than adding reparenting support with complex leaves count
bookkeeping, reject group calls that attempt to change an existing
node's parent. Updates to an existing node's rate or leaves under
the same parent remain permitted. We expect that for any modification
of the topology user should always create new groups and let the
kernel garbage collect the leaf-less nodes.
