isst_if_get_perf_level_mask() and isst_if_get_base_freq_mask() use the
user-provided level as an index into perf_levels[] via
_read_pp_level_info() and _read_bf_level_info(), but neither helper
validates it first.
The adjacent level-info helpers reject levels above max_level before
reading the same per-level register block. Add the same bounds checks to
the mask helpers, and reject disabled SST-PP levels in
isst_if_get_perf_level_mask() to match isst_if_get_perf_level_info().
This prevents out-of-bounds reads from the per-level offset table on
invalid ioctl input.

isst_if_clos_assoc() validates the user-supplied socket_id with
'socket_id > topology_max_packages()', but isst_common.sst_inst[] is
allocated with topology_max_packages() entries, so the valid index range
is [0, topology_max_packages()). The '>' comparison lets
socket_id == topology_max_packages() pass and index one entry past the
array.
In addition, isst_common.sst_inst[socket_id] is NULL for an in-range
package that has no bound TPMI SST instance, and the pointer is used
without a NULL check. Both the out-of-bounds entry and the NULL pointer
are then dereferenced by map_partition_power_domain_id() and the
following power_domain_info access.
Reject socket_id >= topology_max_packages() and a NULL sst_inst, matching
the checks already performed by get_instance().

hsmp_hwmon_write() takes the user-supplied hwmon value as a signed long
and assigns "val / MICROWATT_PER_MILLIWATT" to msg.args[0], which is a
__u32. MICROWATT_PER_MILLIWATT is an unsigned long, so a negative write
to power1_cap (e.g. "echo -1 > power1_cap") is first converted to a huge
unsigned value by the division and then stored into the u32 argument.
As a result a nonsensical, multi-gigawatt socket power limit is sent to
the SMU via HSMP_SET_SOCKET_POWER_LIMIT instead of the write being
rejected.
Reject negative values with -EINVAL before the conversion.
Tested with HSMP enabled:
CAP=$(dirname $(grep -l amd_hsmp_hwmon \
/sys/class/hwmon/hwmon*/name | head -1))/power1_cap
# negative write
echo -1000000 > $CAP ; echo "ret=$?"
# valid positive write must still work
echo 400000000 > $CAP ; echo "ret=$?"
Before:
# echo -1000000 > $CAP ; echo "ret=$?"
ret=0 <- accepted; bogus limit sent to SMU
# echo 400000000 > $CAP ; echo "ret=$?"
ret=0
After:
# echo -1000000 > $CAP ; echo "ret=$?"
bash: echo: write error: Invalid argument
ret=1 <- rejected with -EINVAL
# echo 400000000 > $CAP ; echo "ret=$?"

The outer parsing loop in each attribute-type parser advances "elem"
(the index into the ACPI package element array) by exactly one per
iteration, but cases that consume multi-element arrays
(PREREQUISITES, ENUM_POSSIBLE_VALUES, PSWD_ENCODINGS) read "size"
consecutive elements without adjusting "elem" for the extra entries
consumed beyond the first. The next outer iteration then re-reads a
leftover element from the array just consumed instead of the next
real property, and the type check fails on that stale element,
aborting the parse with -EIO.
This produces exactly the failure visible in dmesg on the test
hardware, on every boot:
Error expected type 2 for elem 13, but got type 1 instead
hp_bioscfg: Returned error 0x3, "Invalid command value/Feature not
supported"
Fix by advancing "elem" by (size - 1) after each array-consuming
loop, so the outer loop's own "elem++" lands on the correct next
element. "eloc" is intentionally left alone: it indexes the logical
property schema, not the physical element array, and each array case
is still exactly one logical property regardless of how many physical
elements it spans.
The defect is identical across all five attribute-type parsers
(enum, integer, string, ordered-list, password), which were
copy-pasted from the same template when the driver was introduced.

The ACPI_TYPE_STRING case explicitly skips the string conversion for
elem == ORD_LIST_ELEMENTS:
if (elem != PREREQUISITES && elem != ORD_LIST_ELEMENTS) {
ret = hp_convert_hexstr_to_str(..., &str_value, &value_len);
if (ret)
continue;
}
so by the time the ORD_LIST_ELEMENTS case in the eloc switch runs,
str_value is NULL (it was freed and reset to NULL at the end of the
previous iteration). That case then does:
ret = hp_convert_hexstr_to_str(str_value, value_len, &tmpstr, &tmp_len);
hp_convert_hexstr_to_str() rejects a NULL input with -EINVAL, which
sends this function to exit_list, and exit_list unconditionally
returns 0. The net effect is that any ordered-list attribute with
elements present silently ends up with an empty elements list, with no
error surfaced anywhere.
Fix by converting the current element directly, order_obj[elem], the
same way the PREREQUISITES case already handles its own array
elements, instead of reusing the unrelated str_value/value_len left
over from earlier processing.

store_password_instance() with is_current = true:
static ssize_t new_password_store(...)

return store_password_instance(kobj, buf, count, true);

The password PSWD_ENCODINGS parser reads password_obj[elem + pos_values]
while copying the supported password encodings from the ACPI package.
The outer loop only guarantees that elem is within password_obj_count.
The encoding count is bounded by MAX_ENCODINGS_SIZE, but that does not
guarantee that the ACPI package contains enough entries for all
elem + pos_values accesses.
A malformed package can therefore declare a non-zero encoding count
without providing enough string objects, causing the parser to read past
the ACPI package array and pass an out-of-bounds string pointer and
length to hp_convert_hexstr_to_str().
Add the same computed-index bounds check used by the other offset-based
package parsing loops before reading password_obj[elem + pos_values].

net: dsa: mt7628 embedded switch initial support
This patch series adds initial support for the MediaTek MT7628 Embedded
Switch.
The driver implements the basic functionality required to operate the
switch using DSA. The hardware provides five internal Fast Ethernet user
ports and one Gigabit port connected internally to the CPU MAC.
Bridge offloading is not yet supported, but due to the CPU to switch
link being Gigabit and all the user ports being Fast Ethernet, software
bridging is a practical solution for the initial driver.
Tested on an MT7628NN-based board.

Add support for the MT7628 embedded switch.
The switch has 5 built-in 100Mbps user ports (ports 0-4) and one 1Gbps
port that is internally attached to the SoCs CPU MAC and serves as the
CPU port.
The switch hardware has a very limited 16 entry VLAN table. Configuring
VLANs is the only way to control switch forwarding. Currently 6 entries
are used by tag_8021q to isolate the ports. Double tag feature is
enabled to force the switch to append the VLAN tag even if the incoming
packet is already tagged, this simulates VLAN-unaware functionality and
simplifies the tagger implementation.

Add support for the MT7628 embedded switch's tag.
The MT7628 tag is merged with the VLAN TPID field when a VLAN is
appended by the switch hardware. It is not installed if the VLAN tag is
already there on ingress. Due to this hardware quirk the tag cannot be
trusted for port 0 if we don't know that the VLAN was added by the
hardware. As a workaround for this the switch is configured to always
append the port PVID tag even if the incoming packet is already tagged.
The tagging driver can then trust that the tag is always accurate and
the whole VLAN tag can be removed on ingress as it's only metadata for
the tagger.
On egress the MT7628 tag allows precise TX, but the correct VLAN tag
from tag_8021q is still appended or the switch will not forward the
packet.

fuse_get_req() parks background allocations on fch->blocked_waitq via
wait_event_state_exclusive(), so each wakeup releases exactly one
waiter. fuse_chan_max_background_set() clears fch->blocked when the
new limit exceeds num_background, but the accompanying wake_up()
releases a single waiter regardless of how many slots just became
available. Raising max_background from 10 to 100 therefore admits one
request instead of ninety.
The remaining waiters are not permanently stranded — the "else if
(!fch->blocked)" branch in fuse_request_end() wakes one more per
completion — but that only helps while requests keep completing.
Consider a fixed pool of threads doing readahead or async direct I/O
with the quota exhausted: every thread is either in flight or parked,
and each completion wakes one waiter while freeing one slot, a net
change of zero. num_background oscillates around the old limit and
the added quota is never taken up.
Waking one waiter per freed slot also preserves submission order:
once fch->blocked is clear, new callers of fuse_get_req() skip the
waitqueue entirely, overtaking waiters that parked before the limit
was raised.
Use wake_up_nr() with the number of slots that just became available.
Since the wakeup is guarded by !fch->blocked, num_background is
strictly below max_background, so the count is at least 1 and never
degenerates into wake_up_all().

====================
net: pse-pd: add Realtek PSE MCU support
This series adds a PSE-PD driver for the microcontroller (MCU) that
fronts the PSE silicon on a range of managed switches, together with its
DT binding.
Hardware model
==============
These boards do not expose the PSE chips to the host directly. A small
microcontroller sits on an I2C/SMBus or UART bus and manages one or more
PSE chips behind it; the host CPU only ever talks to that MCU, using a
fixed 12-byte request/response protocol with a trailing checksum. The
PSE silicon never appears on the bus.
Two generations of the protocol exist, both Realtek's: an older one on
boards with Broadcom PSE silicon (BCM59111, BCM59121) and a newer one
used with Realtek's own PSE silicon (RTL8238B, RTL8239, RTL8239C). They
diverge in opcode numbering and a few response layouts; the driver
abstracts that behind a per-dialect opcode table and parser hooks,
selected by the compatible. The specific PSE chip behind the MCU is
detected at runtime and only influences per-chip constants (power scaling
and the per-port cap).
The compatibles
===============
The protocol compatibles name two generations of the Realtek protocol,
with the I2C framing folded in:
realtek,pse-mcu-gen1 gen1, UART
realtek,pse-mcu-gen1-smbus gen1, I2C/SMBus
realtek,pse-mcu-gen2 gen2, UART
realtek,pse-mcu-gen2-smbus gen2, I2C/SMBus
realtek,pse-mcu-gen2-i2c gen2, raw I2C
and each board carries a device-specific compatible that falls back to one
of these, e.g.
compatible = "zyxel,xs1930-12hp-pse", "realtek,pse-mcu-gen2-smbus";
The naming is the part most likely to raise questions, so the reasoning up
front (the binding documents it too):
- The node describes the MCU together with its Realtek firmware, not a
PSE chip and not the microcontroller silicon. The PSE chips sit behind
the MCU, never appear on the bus, and are reported by the MCU and
detected at runtime; the microcontroller itself is a general-purpose
part (GigaDevice, Nuvoton, ...) that varies across boards. What is
fixed and Realtek's is the firmware and its host protocol - hence the
'realtek' prefix.
- gen1 and gen2 are two generations of that protocol, both Realtek's:
gen1 on older boards fronting Broadcom PSE silicon, gen2 the altered
protocol used once Realtek shipped their own PSE silicon. The
generation is fixed per board and is all the driver needs at DT-parse
time, so the compatible encodes it.
- On I2C the MCU firmware expects one of two framings - SMBus or raw
I2C - which is a genuine programming-model difference, so it is part
of the compatible ('-smbus' / '-i2c'). A UART attachment carries no
framing suffix; the transport is given structurally by the parent
'serial' node.
- Each board additionally carries a device-specific compatible that
falls back to the protocol one. The driver only ever binds on the
protocol compatible; the device-specific string keeps the binding
specific and reserves a place for a future per-board quirk without
having to retrofit device trees already deployed in the field.
Testing
=======
- Linksys LGS328MPCv2 (RTL8238B, I2C)
- Zyxel GS1900-10HP A1 (BCM59121, UART)
- Zyxel GS1900-10HP B1 (RTL8238B, UART)
- Zyxel GS1920-24HPv2 (BCM59121, SMBus)

the MCU as a serdev device and provides the send/recv callbacks the core

A range of managed Realtek-based PoE switches use a small microcontroller
on the PCB to front the actual PSE silicon. The host CPU talks to that
MCU over I2C/SMBus or UART using a fixed 12-byte request/response
protocol with a trailing checksum; the PSE chips are managed by the MCU
and are not accessed directly. Two generations of the protocol exist -
both Realtek's - diverging in opcode numbering and a few response
layouts; the driver handles this with a per-dialect opcode table and
parser hooks for the responses that differ, selected by the compatible.
The specific PSE chip behind the MCU is detected at runtime and only
influences per-chip constants (power scaling and the per-port cap).
This core module implements the protocol, message framing, the dialect
machinery and the pse_controller_ops glue, and exports a registration
helper for transport modules. The I2C and UART transports that drive it
follow in the next patches; the core (PSE_REALTEK_MCU) is selected
automatically by those transports and is not user-selectable on its own.
The realtek-pse-mcu-* files and PSE_REALTEK_MCU* symbols match the
realtek,pse-mcu-* compatibles (see the binding for the naming rationale).
The two protocol generations - gen1 on older Broadcom-PSE boards, gen2 on
Realtek's own PSE silicon - are both Realtek's, handled by the same shared
core, each selecting its dialect via the compatible.
Power budgeting is left to the MCU firmware; the driver advertises
PSE_BUDGET_EVAL_STRAT_DYNAMIC accordingly.

PSE chips behind it never appear on the bus.
The device is the MCU together with its Realtek firmware: the firmware

general-purpose microcontroller they run on. The PSE silicon behind the

Two protocol generations exist, both Realtek's, selected by the

====================
vsock: fix stale sk_err handling after a failed connect
A socket whose connect() failed keeps sk_err set. If that socket is
later reused as a listener, vsock_accept() rejects an unrelated
incoming connection, and on virtio/hyperv the resulting child socket
is leaked.
Patch 1 removes the listener's sk_err check from vsock_accept(), since
no vsock transport ever sets sk_err on a TCP_LISTEN socket. This will
fix what the syzbot reported.
Patch 2 removes vsock_sock.rejected, now unreachable after patch 1.
Patch 3 is a related but separate fix: vsock_connect() now consumes
sk_err via sock_error() once it has been returned to userspace, so a
failed blocking connect() doesn't keep reporting the same error a

vsock_connect() returns sk_err to userspace but does not clear it:
if (sk->sk_err) {
err = -sk->sk_err;
For a blocking connect() the error has already been delivered as
connect()'s return value, so leaving it set causes subsequent operations
like poll()/epoll() to keep reporting POLLERR even though the connect
failure was already delivered.
The error should be consumed once it has been returned to userspace.
Switch to sock_error(), which reads and clears sk_err atomically,
matching the behavior of other protocol implementations such as
__inet_stream_connect().

After previous patch, the branch marking a socket rejected in
vsock_accept() is unreachable, and nothing ever sets vsk->rejected
elsewhere.
In fact, since commit d021c344051a ("VSOCK: Introduce VM Sockets"),
where `rejected` was introduced, there has never been a path that sets
sk_err on a listening socket, so that branch has been dead code since
the beginning.
Therefore, we can remove the `rejected` field from vsock_sock structure.

Syzbot reported an issue which can be reproduced with these steps:
r0 = socket(AF_VSOCK, SOCK_STREAM, 0)
bind(r0, {VMADDR_CID_ANY, PORT})
connect(r0, {VMADDR_CID_LOCAL, PORT}) -> -1, EPROTO (self-connect)
listen(r0, backlog) -> 0
r1 = socket(AF_VSOCK, SOCK_STREAM, 0)
connect(r1, {VMADDR_CID_LOCAL, PORT}) -> 0
accept(r0) -> -1, EPROTO (stale sk_err)
Basically, it creates a socket (r0) and triggers a self-connect after
binding it. This self-connect fails with EPROTO because it loops back
to r0 while the socket is still in the TCP_SYN_SENT state, causing it
to be incorrectly dispatched to the connecting-client path. The
unexpected packet type encountered there sets sk_err to EPROTO.
After that, it invokes a listen() call on the same socket. This
listen() call succeeds because the kernel's listening path never
inspects or clears sk_err. Then, a new socket (r1) is created as a
normal client and connects to r0. However, vsock_accept() rejects this
incoming connection because the listener's sk_err still holds the
EPROTO error from the earlier failed self-connect.
This rejection causes the child socket created for r1's connection to
never be freed on virtio or hyperv transports; only the VMCI transport
implements pending_work to revisit and clean up a rejected socket.
For a non-blocking connect(), vsock_connect() may return -EINPROGRESS
immediately, and vsock_connect_timeout() can later set sk->sk_err
asynchronously.
Since no vsock transport ever sets sk_err on a socket while it is in
TCP_LISTEN state, checking it in vsock_accept() serves no purpose and
only carries forward errors left behind by earlier, unrelated
connection attempts on the same socket. Remove the checks so accept()
no longer rejects valid incoming connections because of a stale
error, which also avoids the resource leak described above.

fuse_init_server_timeout() limits timeout to fuse_max_req_timeout with
the same logic as min_not_zero(), and returns early exactly when the
computed timeout would be zero.
So use min_not_zero() instead and return when the computed timeout is
zero.
No functional change.

validate_password_input() computes length = strlen(buf) and then
checks buf[length - 1] to strip a trailing newline, without checking
that length is nonzero first. Writing an empty string (a bare '\n')
to current_password or new_password gives length == 0, and
buf[length - 1] reads buf[-1], one byte before the heap allocation
holding the copied input.
KASAN confirms this directly:
BUG: KASAN: slab-out-of-bounds in store_password_instance.constprop.0+0x223/0x2a0 [hp_bioscfg]
Read of size 1 at addr ffff88811bd8da9f by task sh/13740
...
store_password_instance.constprop.0+0x223/0x2a0 [hp_bioscfg]
current_password_store+0x14/0x20 [hp_bioscfg]
...
The buggy address is located 23 bytes to the right of
allocated 8-byte region [ffff88811bd8da80, ffff88811bd8da88)
Reproduced identically via new_password_store. Execution continues
past the bad read (the garbage byte only affects whether "length" is
decremented by one), so the write completes and returns success; this
is a pure information read past the buffer, not a crash, but it is
still an out-of-bounds access KASAN correctly flags.
Fix by only checking buf[length - 1] when length is nonzero.

sk_store() and kek_store() strip a trailing newline from the sysfs
write before allocating the key buffer:
length = count;
if (buf[length - 1] == '\n')
length--;
bioscfg_drv.spm_data.signing_key = kmemdup(buf, length, GFP_KERNEL);
but then pass the original "count" (not "length") as the copy size to
hp_wmi_perform_query(), which memcpy()s that many bytes out of the
"length"-sized allocation, reading one byte past it whenever the write
ends in a newline, the normal case for a shell "echo" into sysfs.
KASAN confirms this directly:
BUG: KASAN: slab-out-of-bounds in hp_wmi_perform_query+0x1e9/0x460 [hp_bioscfg]

Reproduced identically for kek_store, and at multiple write sizes
(28, 57, 201 bytes), each time reading exactly one byte past a
kmemdup() allocation one byte smaller than the write.
Fix by passing "length" instead of "count" to hp_wmi_perform_query()
in both functions.

hp_get_string_from_buffer() clamps the converted string length against
the destination buffer size with "size > dst_size", so when the
converted length is exactly equal to dst_size, conv_dst_size is left
at dst_size and the unconditional NUL terminator write
dst[conv_dst_size] = 0;
lands one byte past the destination buffer. This is the same shape of
bug as the previously fixed off-by-one in hp_convert_hexstr_to_str():
the buffer is sized correctly for the content, but the terminator
write is never checked against that size.
Fix by changing the comparison to ">=" so conv_dst_size is always left
with room for the terminator.
All fixed-size destinations that reach this function (path[512],
current_value[512], current_password/current_value[64], and the
per-entry buffers in encodings[][512] and prerequisites[][512]) are
affected.

KVM x86 misc changes for 7.3
- Fix VPID virtualization bugs where KVM would fail to flush hardware TLBs.
- Harden the SNP and TDX "populate" ioctls against bad input, and to prepare
for supporting in-place private<=>shared conversion.
- Fix a variety of #DB priority bugs.
- Fix a class of races related to enabling Hyper-V emulation on a vCPU after
the vCPU is visible to the rest of KVM.
- Use static calls for nested virtualization ops.
- Move more KVM-internal code out of x86's kvm_host.h.
- Enumerate support for a variety of Zhaoxin instructions that don't require
explicit virtualization.
- Fix missing EFER validation bugs, including in the KVM_SET_SREGS* path.

KVM SVM changes for 7.3
- Remove a dying VM from the GA Log notifier list before the VM is actually
destroyed, to fix a potential use-after-free.
- Don't pass FOLL_WRITE when registering encrypted memory regions, i.e. when
pinning SEV/SEV-ES guest memory, to fix a regression with file-backed memory
introduced by KVM's (correct) usage of long-term pins.
[This is correct because, while FOLL_WRITE was needed in the past to trigger
CoW unsharing, nowadays FOLL_LONGTERM does that already even without
FOLL_WRITE. And in fact, get_user_pages() actually disallows FOLL_WRITE
together with FOLL_LONGTERM. This change was acked by the MM maintainers.
For more inforamtion see commit ee1a586dd1fa2f245b3b753a3e44d9263a49240b.

- Allocate full pages for SEV/SEV-ES {DE,EN}CRYPT ops on SNP-enabled hosts to
fix a data corruption issue due to the PSP driver assigning to-be-written
pages to firmware (as required by the SNP specs).

KVM selftests changes for 7.3, part 2

KVM_IRQFD + KVM_SET_GSI_ROUTING, with optional support for triggering IRQs
via writes to an assigned VFIO device.
- Add syscall wrappers to assert success on a variety of pthreads and CPU
affinity APIs.
- Set vCPU pthread affinity as early as possible to reduce contention issues
that were surfaced by PREEMPT_LAZY, which result in runtimes of over a
minute on large hosts, versus the expected ~5 seconds.
- Rework the PMU counters test to run each testcase using a single VM with
many vCPUs for each sub-testcase, instead of using a unique VM for each
