5e4cc258b3 platform/x86: x86-android-tablets: Add include defining struct dmi_system_id
Currently <linux/i2c.h> includes <linux/mod_devicetable.h> transitively
which ensures that struct dmi_system_id is defined in
drivers/platform/x86/x86-android-tablets/x86-android-tablets.h. However
this include in <linux/i2c.h> will be replaced by one for i2c_device_id
only. To ensure that dmi_system_id is available add the include for that
explicitly.

6d924c42e0 i2c: Let i2c-core.h include <linux/i2c.h>
The subsystem private header i2c-core.h uses several symbols defined in
<linux/i2c.h>, e.g. struct i2c_board_info and i2c_lock_bus()). This
doesn't pose a problem in practise because all files including
"i2c-core.h" also include <linux/i2c.h>.

To make this more robust add an include statement for <linux/i2c.h>
making the header self-contained.

2fb03de525 of: Explicitly include <linux/types.h> and <linux/err.h>
<linux/of_platform.h> uses resource_size_t and relies on the transitive
include <linux/mod_devicetable.h> -> <linux/types.h>. It also uses error
constants and thus relying on the include chain
<linux/mod_devicetable.h> -> <linux/uuid.h> -> <linux/string.h> ->
<linux/err.h>.

With the plan to split <linux/mod_devicetable.h> per subsystem and then
only letting of_platform.h include the of-specific bits (which don't
require these two headers), add the needed includes explicitly to keep
the header self-contained.

00cd8fc630 driver core: platform: Include header for struct platform_device_id
Platform drivers can define an array containing the supported device
variants to be assigned to the struct platform_driver's .id_table.

While a forward declaration of struct platform_device_id is technically
enough to make the driver self-contained, it's reasonable to provide the
(very lightweight) data type definition for that array in
<linux/platform_device.h> to not add that burden to all platform drivers
with an id-table.

Note that currently <linux/device.h> transitively includes
<linux/mod_devicetable.h> that provides struct platform_device_id. But
that include is planned to be replaced by a tighter set of includes that
only define the structures relevant for the stuff in <linux/device.h>.

ad428f5811 mod_devicetable.h: Split into per subsystem headers
<linux/mod_devicetable.h> is included transitively in nearly every
driver in an x86_64 allmodconfig build of v7.1:

	$ find drivers -name \*.o -not -name \*.mod.o | wc -l
	21330
	$ find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l mod_devicetable.h | wc -l
	17038

The result is that even when touching an obscure device id struct most
of the kernel needs to be recompiled. Given that each driver typically
only needs one or two of these structures, splitting into per subsystem
headers and only including what is really needed reduces the amount of
needed recompilation.

Implement the first step and define each device id struct in a separate
header (together with its associated #defines).

<linux/mod_devicetable.h> is modified to include all the new headers to
continue to provide the same symbols.

Several headers currently include <linux/mod_devicetable.h>, those that
are most lukrative to include only their subsystem headers only are:

	$ git -C source grep -l mod_devicetable.h include/linux | while read h; do echo -n "$h:"; find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l $h | wc -l; done | sort -t: -k2 -n -r | head
	include/linux/of.h:10897

	include/linux/i2c.h:5402

	include/linux/usb.h:1222
	include/linux/input.h:1205
	include/linux/mdio.h:835
	include/linux/phy.h:733

struct cpu_feature isn't really a device_id struct. That is kept in
<linux/mod_devicetable.h> for now.

cd64be0ecd ata: libata-scsi: limit simulated SCSI command copy to response length
The function ata_scsi_rbuf_fill() is used to copy the response of
emulated SCSI commands from ata_scsi_rbuf to the SCSI command's
scatterlist.

Currently, sg_copy_from_buffer() is called with the size argument
set to ATA_SCSI_RBUF_SIZE (2048 bytes). Since ata_scsi_rbuf is
zeroed out before the simulation actor is invoked, copying the
full buffer size causes the remainder of the SCSI command's
transfer buffer (beyond the actual response length 'len') to be
overwritten with zeroes. This clobbers any pre-existing sentinel
values or data in the caller's buffer tail, even though the
correct residual count is reported via scsi_set_resid().

Fix this by passing the actual response length 'len' as the copy
size to sg_copy_from_buffer(), ensuring that the tail of the
caller's buffer remains untouched. Also, add a defensive check
to ensure that the actor does not return a length exceeding the
static buffer capacity. If this occurs, trigger a WARN_ON(),
fail the command with an aborted command error, and return
immediately without copying any data.

The fix was tested by invoking an SCSI SG_IO INQUIRY on
an ATA disk on vanilla build, and build with the fix. Confirmed
that the input buffer's tail end remains unmodified with the fix.

533a0b940f ata: libata-core: Reject an invalid concurrent positioning ranges count
ata_dev_config_cpr() takes the number of range descriptors from buf[0]
of the concurrent positioning ranges log (up to 255), which the device
reports independently of the log size in the GPL directory. The count is
then walked at a fixed 32-byte stride in two places with no bound: the
log read here, and the INQUIRY VPD page B9h emitter, which writes one
descriptor per range into the fixed 2048-byte ata_scsi_rbuf. A device
reporting a count larger than its own log overflows the read buffer (up
to 7704 bytes past a 512-byte slab), and a count above 62 overflows the
response buffer on the emit side.

Bound the count once, on probe, against both the log the device returned
and the number of descriptors the VPD B9h response buffer can hold
(ATA_DEV_MAX_CPR, derived from the rbuf size). Reject an out-of-range
count with a warning; this keeps the emitter in bounds with no separate
change there.

2b7858891b wifi: rtlwifi: disable ASPM for RTL8723BE with subsystem ID 17aa:b736
RTL8723BE outputs a large amount of PCIe AER errors during and
after boot, even before probe and when driver is never loaded.
This causes significant system slowdown.

The errors are the same as reported by
commit 77a6407c6a ("wifi: rtlwifi: disable ASPM for RTL8723BE with subsystem ID 11ad:1723")

Add the RTL8723BE with subsystem ID 17aa:b736 to the rtl_aspm_quirks
table to stop the AER errors. AER errors can still be present prior to
pci probe, as the device by default may have ASPM enabled.

Testing on a Razer Blade 14 2017 which shipped from the
OEM equipped with an RTL8723BE card with this subsystem ID
confirms that this patch resolves the AER flood and allows the
wireless card to function normally once the driver takes over.

04a46c2dbf wifi: rtlwifi: fix disabling of ASPM for RTL8723BE with AER flooding
commit 77a6407c6a ("wifi: rtlwifi: disable ASPM for RTL8723BE with subsystem ID 11ad:1723")
adds code which sets ppsc->support_aspm to false in
_rtl_pci_update_default_setting() in order to disable ASPM.
This does not, however, disable ASPM. Rather, it disables driver
control of ASPM, and blocks calls to rtl_pci_enable_aspm()
and rtl_pci_disable_aspm().

In some cases, the pci device supplied to the probe function has
ASPM enabled. The code would therefore not disable ASPM, as it means to,
but rather just leave it enabled.
This was discovered through testing on a Razer Blade 14 2017.

Implement a new __rtl_pci_disable_aspm(hw) function which does not check
ppsc->support_aspm before disabling and call it from
rtl_pci_disable_aspm().

Then move the code added in the previous commit to rtl_pci_init_aspm() to
allow adding a call to __rtl_pci_disable_aspm(hw).
This makes sure ASPM is disabled while still disabling
driver control of ASPM to block it from being enabled later.

Sniffer mode is enabled by default in the RX filter on Wi-Fi 7 chips,

c99498b4cb wifi: rtw89: drop packet offload entry on H2C addition failure to avoid scan issue
A special case is when C2H done ack has been completed, but the
corresponding packet offload response has not actually been received,
which causes the add packet offload to fail. In this state, firmware
treats the entry as added, so subsequent add requests for the same id
are rejected as duplicates. To recover from this, send a delete packet
offload H2C command to roll back the normal state. It has been tested and
verified to have no functional side effect.

The UDM1 is user define message to record count of H2C command sent by

Otherwise, throw a warning.

d1ceb2b232 platform/chrome: sensorhub: Fix memory overread in ring handler
`max_response` and `sensor_num` are read from different EC commands:

- `max_response` is from cros_ec_get_proto_info().
    ec_dev->max_response = info->max_response_packet_size -
                                    sizeof(struct ec_host_response);

- `sensor_num` is from cros_ec_get_sensor_count().
    sensor_num = cros_ec_get_sensor_count(ec);

With a malfunctioning EC firmware, it is possible that the `msg->insize`
(i.e., `fifo_info_length` in the context) could be clamped in
cros_ec_cmd_xfer() because `msg->insize` is greater than `max_response`.

    int fifo_info_length =
            sizeof(struct ec_response_motion_sense_fifo_info) +
            sizeof(u16) * sensorhub->sensor_num;

This means the number of read bytes could be less than expected.  As a
result, the subsequent memcpy() in cros_ec_sensorhub_ring_handler()
overreads the `resp->fifo_info` buffer.

Check the return value of cros_ec_cmd_xfer_status() and abort if the
number of bytes read does not match the expected length.

ed4f05d9f2 wifi: rtlwifi: rtl8192du: check QoS TID before indexing tids
rtl92du_tx_fill_desc() uses ieee80211_get_tid() to read the QoS TID
from the 802.11 header and then uses it as an index into
sta_entry->tids[]. ieee80211_get_tid() returns the low 4-bit QoS TID
value, so the result can be in the range 0..15.

rtlwifi only allocates MAX_TID_COUNT entries for sta_entry->tids[], and
MAX_TID_COUNT is 9. A QoS TID greater than 8 therefore indexes past the
aggregation state array. Keep the default RTL_AGG_STOP state for
out-of-range TIDs, matching rtl92cu_tx_fill_desc().

This issue was detected by our static analysis tool and confirmed by
manual audit. UBSAN validation for the same bug pattern reports an
array-index-out-of-bounds access with index 10 for type
'rtl_tid_data [9]'.

e779df4806 wifi: rtw88: pci: fix resource leak on failed NAPI setup
rtw_pci_probe() allocates PCI resources through
rtw_pci_setup_resource() before it sets up NAPI. If
rtw_pci_napi_init() fails, the error path jumps straight to
err_pci_declaim and skips rtw_pci_destroy(), leaving the PCI
resources allocated by rtw_pci_setup_resource() behind.

Add a dedicated cleanup label for the NAPI setup failure path so probe
destroys the PCI resources.

The bug was first flagged by an experimental analysis tool we are
developing for kernel memory-management bugs while analyzing current
mainline kernels. The tool is still under development and is not yet
publicly available. Manual inspection confirms that the bug is still
present in v7.1-rc7.

An x86_64 allyesconfig build showed no new warnings. As we do not have a
suitable rtw88 PCI board to test with, no runtime testing was able to be
performed.
