ntfs: fix empty_buf and ra lifetime bugs in ntfs_empty_logfile()
ntfs_empty_logfile() has three related allocator bugs around the
@empty_buf and @ra buffers it uses inside the per-cluster loop.
When the loop encounters a runlist entry with LCN_RL_NOT_MAPPED, the
function kvfrees @empty_buf and goes to map_vcn to remap. @empty_buf
is not cleared. If ntfs_map_runlist_nolock() fails on re-entry,
control jumps to the err label which kvfrees @empty_buf a second time.
In the same branch, @ra is left allocated. When the remap succeeds
the function falls through the @empty_buf re-allocation and the @ra
re-allocation, overwriting the previous @ra pointer and leaking it.
The success path frees @empty_buf with kfree() instead of kvfree().
kvzalloc() may fall back to vmalloc(), in which case kfree() does not
correctly release the memory.
A KASAN-enabled QEMU harness mirroring this control flow reports
"BUG: KASAN: double-free" when the second ntfs_map_runlist_nolock()
fails.
Clear both @empty_buf and @ra after the in-loop releases so the err
path is a no-op when the buffers have already been freed and so the
remap-success path does not leak the previous @ra. Switch the success
path to kvfree() to match the @empty_buf allocator.

lib/crypto: powerpc/md5: Drop powerpc optimized MD5 code
MD5 is obsolete, is vulnerable to collision attacks, and is being
replaced by SHA-256 in new systems. It doesn't make sense to continue
to maintain architecture-optimized implementations of MD5. Effort
should be spent on modern algorithms.
Indeed, architecture-optimized MD5 code remains only for powerpc. It
was already removed from mips and sparc, and it never existed for any
other architecture (e.g. x86, arm, or arm64) in the first place.
Earlier the decision was made to keep the powerpc MD5 code for a while
anyway because of someone using it via AF_ALG via libkcapi-hasher
(https://lore.kernel.org/r/f0d771d5-ed70-444c-957a-ad4c16f6c115@csgroup.eu/)
However, with AF_ALG itself now being on its way out due to its
continuous stream of security vulnerabilities
(https://lore.kernel.org/r/20260430011544.31823-1-ebiggers@kernel.org/),
it's also time to be a bit more forceful with nudging people towards
userspace crypto code. It's always been the better solution anyway, and
it's much more efficient if properly optimized code is used.
Note that the md5-asm.S file contains no privileged instructions and
could be run in userspace just fine.
Thus, we now have two factors going against keeping the powerpc MD5
code. Different people might weigh these two factors differently, but I
think the two of them together make the removal the clear choice.

ntfs: validate attribute name bounds before returning it
ntfs_attr_find() validates a named attribute before comparing it with the
requested name, but that check is currently after the AT_UNUSED handling.
When callers enumerate attributes with AT_UNUSED, ntfs_attr_find() can
return a malformed named attribute before checking whether name_offset
and name_length stay within the attribute record.
Some enumeration callers use the returned attribute name pointer
directly. For example, one path passes (attr + name_offset, name_length)
to ntfs_attr_iget(), where the name can later be copied according to
name_length. A malformed on-disk name_offset/name_length pair should not
be exposed to those callers.
Move the existing name bounds validation before returning attributes
during AT_UNUSED enumeration, and write it as an offset/remaining-size
check so the subtraction cannot underflow. Extract the converted values
into local variables (name_offset, attr_len, name_size) to make the
intent explicit and avoid repeating the endian conversions inside the
bounds check. This keeps matching attributes on the same checked path
while also covering attribute enumeration.
A small userspace ASAN model with attr length=32, name_offset=124 and
name_length=8 reproduces a heap-buffer-overflow read in the old
enumeration path. With this change the same malformed attribute is
rejected before the name pointer is returned to the caller.

bitmap scan in ntfs_mft_bitmap_find_and_alloc_free_rec_nolock() also
guards against this overflow but uses a strict greater than comparison,
allowing record number 2^32 itself through this earlier check.
Every other 2^32 boundary check in fs/ntfs/mft.c uses '>=', so the
strict greater than here is both a real off-by-one and an internal
inconsistency. A model with ll == 2^32 confirms the current check
accepts the value while the corrected check rejects it.
Use '>=' so the boundary matches the layout-time rejection and the

ntfs: validate MFT attrs_offset against bytes_in_use
ntfs_mft_record_check() verifies that attrs_offset is aligned and that
the resulting pointer stays within the allocated MFT record buffer, but
it does not check that the first attribute header starts within the
bytes_in_use area.
A malformed record with attrs_offset greater than bytes_in_use can pass
this check as long as attrs_offset is still within bytes_allocated. The
attribute parser then computes the remaining record space by subtracting
the attribute pointer from bytes_in_use. Because that value is unsigned,
the subtraction can underflow and allow bytes after bytes_in_use to be
interpreted as an attribute.
Reject records where attrs_offset is outside bytes_in_use or where the
used area does not even contain the four-byte attribute type/AT_END
terminator at attrs_offset.
A small userspace model with attrs_offset=128 and bytes_in_use=64 shows
the current check accepts the record and the parser space calculation
underflows to 0xffffffc0. With this change the same malformed record is

ntfs: fix missing kstrdup() error check in ntfs_write_volume_label()
ntfs_write_volume_label() does not check the return value of
kstrdup(). If the allocation fails, vol->volume_label is set to
NULL while the function returns success. A subsequent
FS_IOC_GETFSLABEL then returns an empty string even though the
on-disk label was updated correctly.
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.
Also move mark_inode_dirty_sync() into the success path so that it
is not called when no metadata was actually modified.

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.

net: dsa: microchip: hook up ksz_switch_alloc() to chip-specific dsa_switch_ops
Now that each switch driver has its own dsa_switch_ops (currently a copy
of ksz_switch_ops), we no longer need ksz_switch_ops and can remove it.
Get to the driver-specific dsa_switch_ops through the ksz_chip_data
structure.
Reorder the alloc()/get_match_data() calls such as to have that
pointer available.

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.

the eSwitch structure and translate the vhca_id to function type for the
functions to which it supplies pages. The next patch will add support
for page management in vhca_id mode.

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
- mlx5_devlink_port_fn_migratable_get() - reads cached vport state
- mlx5_devlink_port_fn_roce_get() - reads cached vport state
- mlx5_devlink_port_fn_max_io_eqs_get() - queries other function caps
- mlx5_esw_vport_enable/disable() - vhca_id map/unmap
Functions that perform also set_hca_cap (migratable_set, roce_set,
max_io_eqs_set, esw_ipsec_vf_set_generic, esw_ipsec_vf_set_bytype)

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.
9) Fix a race condition in ebtables module initialization, similar to
previous patch.
10) Restore propagation of helper to expected connection, this is a
fix-for-recent-fix.
11) Validate that the expectation tuple and mask netlink attributes are
present when adding expectation via nfqueue, this fixes a possible
null-ptr-deref.
12) Fix possible rare memleak in the SIP helper in case helper has been
