[ Upstream commit 2b660ee10a ]
In vendor driver, size of group cal and dpd cal for mt7981 includes 6G
although the chip doesn't support it.
mt76 doesn't take this into account which results in reading from the
incorrect offset.
For devices with precal, this would lead to lower bitrate.
Fix this by aligning groupcal size with vendor driver and switch to
freq_list_v2 in mt7915_dpd_freq_idx in order to get the correct offset.
Below are iwinfo of the test device with two clients connected
(iPhone 16, Intel AX210).

[ Upstream commit 7dfd80f70e ]
When the watchdog gets enabled with this driver, it leaves enough time
for the core watchdog subsystem to start pinging it. But when the
watchdog is already started by hardware or by the boot loader, little
time remains before it fires and it happens that the core watchdog
subsystem doesn't have time to start pinging it.
Until commit 19ce9490aa ("watchdog: mpc8xxx: use the core worker
function") pinging was managed by the driver itself and the watchdog
was immediately pinged by setting the timer expiry to 0.
So restore similar behaviour by pinging it when enabling it so that
if it was already enabled the watchdog timer counter is reloaded.

[ Upstream commit 944b6b216c ]
KCSAN reported a data-race on the `ipvs->enable` flag, which is
written in the control path and read concurrently from many other
contexts.
Following a suggestion by Julian, this patch fixes the race by
converting all accesses to use `WRITE_ONCE()/READ_ONCE()`.
This lightweight approach ensures atomic access and acts as a
compiler barrier, preventing unsafe optimizations where the flag
is checked in loops (e.g., in ip_vs_est.c).
Additionally, the `enable` checks in the fast-path hooks
(`ip_vs_in_hook`, `ip_vs_out_hook`, `ip_vs_forward_icmp`) are
removed. These are unnecessary since commit 857ca89711
("ipvs: register hooks only with services"). The `enable=0`
condition they check for can only occur in two rare and non-fatal
scenarios: 1) after hooks are registered but before the flag is set,
and 2) after hooks are unregistered on cleanup_net. In the worst
case, a single packet might be mishandled (e.g., dropped), which
does not lead to a system crash or data corruption. Adding a check
in the performance-critical fast-path to handle this harmless
condition is not a worthwhile trade-off.

[ Upstream commit 0f85406bf8 ]
There is an issue with the handling of negative channel scales
in iio_convert_raw_to_processed_unlocked() when the channel-scale
is of the IIO_VAL_INT_PLUS_[MICRO|NANO] type:
Things work for channel-scale values > -1.0 and < 0.0 because of
the use of signed values in:
*processed += div_s64(raw64 * (s64)scale_val2 * scale, 1000000LL);
Things will break however for scale values < -1.0. Lets for example say
that raw = 2, (caller-provided)scale = 10 and (channel)scale_val = -1.5.
The result should then be 2 * 10 * -1.5 = -30.
channel-scale = -1.5 means scale_val = -1 and scale_val2 = 500000,
now lets see what gets stored in processed:
1. *processed = raw64 * scale_val * scale;
2. *processed += raw64 * scale_val2 * scale / 1000000LL;
1. Sets processed to 2 * -1 * 10 = -20
2. Adds 2 * 500000 * 10 / 1000000 = 10 to processed
And the end result is processed = -20 + 10 = -10, which is not correct.
Fix this by always using the abs value of both scale_val and scale_val2
and if either is negative multiply the end-result by -1.
Note there seems to be an unwritten rule about negative
IIO_VAL_INT_PLUS_[MICRO|NANO] values that:
i. values > -1.0 and < 0.0 are written as val=0 val2=-xxx
ii. values <= -1.0 are written as val=-xxx val2=xxx
But iio_format_value() will also correctly display a third option:
iii. values <= -1.0 written as val=-xxx val2=-xxx
Since iio_format_value() uses abs(val) when val2 < 0.
This fix also makes iio_convert_raw_to_processed() properly handle
channel-scales using this third option.

[ Upstream commit 0dc7117da8 ]
Index allocation requires at least one bit in the $BITMAP attribute to
track usage of index entries. If the bitmap is empty while index blocks
are already present, this reflects on-disk corruption.
syzbot triggered this condition using a malformed NTFS image. During a
rename() operation involving a long filename (which spans multiple
index entries), the empty bitmap allowed the name to be added without
valid tracking. Subsequent deletion of the original entry failed with
-ENOENT, due to unexpected index state.
Reject such cases by verifying that the bitmap is not empty when index
blocks exist.

[ Upstream commit 736fc7bf5f ]
The MFT record relative to the file being opened contains its runlist,
an array containing information about the file's location on the physical
disk. Analysis of all Call Stack paths showed that the values of the
runlist array, from which LCNs are calculated, are not validated before
run_unpack function.
The run_unpack function decodes the compressed runlist data format
from MFT attributes (for example, $DATA), converting them into a runs_tree
structure, which describes the mapping of virtual clusters (VCN) to
logical clusters (LCN). The NTFS3 subsystem also has a shortcut for
deleting files from MFT records - in this case, the RUN_DEALLOCATE
command is sent to the run_unpack input, and the function logic
provides that all data transferred to the runlist about file or
directory is deleted without creating a runs_tree structure.
Substituting the runlist in the $DATA attribute of the MFT record for an
arbitrary file can lead either to access to arbitrary data on the disk
bypassing access checks to them (since the inode access check
occurs above) or to destruction of arbitrary data on the disk.
Add overflow check for addition operation.

The correct barrier usage here is after the generation check, so that

need to stop polling. Debatable on coherent DMA as the Rx descriptor
size is <= cacheline size, but anyway, the current barrier position

Instead allow sending Modem Status Command without waiting for remote

Port of commit 227545b9a0 ("drm/radeon/dpm: Disable sclk
switching on Oland when two 4K 60Hz monitors are connected")
This is an ad-hoc DPM fix, necessary because we don't have
proper bandwidth calculation for DCE 6.
We define "high pixelclock" for SI as higher than necessary
for 4K 30Hz. For example, 4K 60Hz and 1080p 144Hz fall into
this category.
When two high pixel clock displays are connected to Oland,
additionally disable shader clock switching, which results in
a higher voltage, thereby addressing some visible flickering.

[ Upstream commit ce02513012 ]
Based on some comments in dm_pp_display_configuration
above the crtc_index and line_time fields, these values
are programmed to the SMC to work around an SMC hang
when it switches MCLK.
According to Alex, the Windows driver programs them to:
mclk_change_block_cp_min = 200 / line_time
mclk_change_block_cp_max = 100 / line_time
Let's use the same for the sake of consistency.
Previously we used the watermark values, but it seemed buggy
as the code was mixing up low/high and A/B watermarks, and
was not saving a low watermark value on DCE 6, so
mclk_change_block_cp_max would be always zero previously.
Split this change off from the previous si_upload_smc_data
to make it easier to bisect, in case it causes any issues.

The si_upload_smc_data function uses si_write_smc_soft_register

to be PPSMC_Result_OK which is 1.
The PPSMC_Result_OK / PPSMC_Result_Failed values are used for
checking the result of a command sent to the SMC.
However, the si_write_smc_soft_register actually doesn't send
any commands to the SMC and returns zero on success,
so this check was incorrect.

The mlx5 driver currently derives max_qp_wr directly from the
log_max_qp_sz HCA capability:
props->max_qp_wr = 1 << MLX5_CAP_GEN(mdev, log_max_qp_sz);
However, this value represents the number of WQEs in units of Basic
Blocks (see MLX5_SEND_WQE_BB), not actual number of WQEs. Since the size
of a WQE can vary depending on transport type and features (e.g., atomic
operations, UMR, LSO), the actual number of WQEs can be significantly
smaller than the WQEBB count suggests.
This patch introduces a conservative estimation of the worst-case WQE size
— considering largest segments possible with 1 SGE and no inline data or
special features. It uses this to derive a more accurate max_qp_wr value.

For a direct attached device, attached_phy contains the local phy id.
For a device behind an expander, attached_phy contains the remote phy
id, not the local phy id.
I.e. while pm8001_ha will have pm8001_ha->chip->n_phy local phys, for a
device behind an expander, attached_phy can be much larger than
pm8001_ha->chip->n_phy (depending on the amount of phys of the
expander).
E.g. on my system pm8001_ha has 8 phys with phy ids 0-7. One of the
ports has an expander connected. The expander has 31 phys with phy ids
0-30.
The pm8001_ha->phy array only contains the phys of the HBA. It does not
contain the phys of the expander. Thus, it is wrong to use attached_phy
to index the pm8001_ha->phy array for a device behind an expander.
Thus, we can only clear phy_attached for devices that are directly
attached.
