The stmmac supports up to 4 auxiliary snapshots that can be enabled by
setting the appropriate bits in the PTP_ACR bitfield.
Previously as of commit f4da56529da6 ("net: stmmac: Add support for
external trigger timestamping") instead of setting the bits, a fixed
value was written to this bitfield instead of passing the appropriate
bitmask.
Now the correct bit is set according to the ptp_clock_request.extts_index
passed as a parameter to stmmac_enable().

With CONFIG_TI_K3_AM65_CPSW_NUSS=y and CONFIG_TI_ICSSG_PRUETH=m,
k3-cppi-desc-pool.o is linked to a module and also to vmlinux even though
the expected CFLAGS are different between builtins and modules.
The build system is complaining about the following:
k3-cppi-desc-pool.o is added to multiple modules: icssg-prueth
ti-am65-cpsw-nuss
Introduce the new module, k3-cppi-desc-pool, to provide the common
functions to ti-am65-cpsw-nuss and icssg-prueth.

The datatype of rx_coalesce_usecs is u32, always larger or equal to zero.
Previous checking does not include value 0, this patch removes the
checking to handle the value 0. This change in behaviour making the
value of 0 cause an error is not a problem because 0 is out of
range of rx_coalesce_usecs.

Add PM ops for Suspend to Idle. When the system suspended,
the Ethernet Serdes's clock will be stopped. So, this driver needs
to re-initialize the Ethernet Serdes by phy_init() in
renesas_eth_sw_resume(). Otherwise, timeout happened in phy_power_on().

Enabling KASAN and running some iperf tests raises some memory issues with
vmm_table:
BUG: KASAN: slab-out-of-bounds in wilc_wlan_handle_txq+0x6ac/0xdb4
Write of size 4 at addr c3a61540 by task wlan0-tx/95
KASAN detects that we are writing data beyond range allocated to vmm_table.
There is indeed a mismatch between the size passed to allocator in
wilc_wlan_init, and the range of possible indexes used later: allocation
size is missing a multiplication by sizeof(u32)

DCFO tracking compensate the CFO (carrier frequency offset) by digital
hardware that provides fine CFO estimation. Although the avg_cfo which
is a coarse information becomes zero, still we need DCFO tracking to
compensate the residual CFO. However, the original flow skips the case
when avg_cfo is zero, so we fix it to have expected performance.

Change naming to disambiguate the functions because their names are common
and not clear about the purpose. Not change logic at all.
These functions are to control baseband AGC while BT coexists with WiFi.
Among these functions, ctrl_btg_bt_rx is used to control AGC related
settings, which is affected by BT RX, while BT shares the same path
with wifi; ctrl_nbtg_bt_tx is used to control AGC settings under
non-shared path condition, which is affected by BT TX.

`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We expect netdev->name to be NUL-terminated based on its use with format
strings:
| if (q_vector->rx.ring && q_vector->tx.ring)
| sprintf(q_vector->name, "%s-TxRx-%u", netdev->name,
Furthermore, we do not need NUL-padding as netdev is already
zero-allocated:
| netdev = alloc_etherdev_mq(sizeof(struct igc_adapter),
| IGC_MAX_TX_QUEUES);
...
alloc_etherdev() -> alloc_etherdev_mq() -> alloc_etherdev_mqs() ->
alloc_netdev_mqs() ...
| p = kvzalloc(alloc_size, GFP_KERNEL_ACCOUNT | __GFP_RETRY_MAYFAIL);
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.

`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
Moreover, `strncat` shouldn't really be used either as per
fortify-string.h:
* Do not use this function. While FORTIFY_SOURCE tries to avoid
* read and write overflows, this is only possible when the sizes
* of @p and @q are known to the compiler. Prefer building the
* string with formatting, via scnprintf() or similar.
Instead, use `scnprintf` with "%s%s" format string. This code is now
more readable and robust.

The "...-1" pattern makes it evident that netdev->name is expected to be
NUL-terminated.
Meanwhile, it seems NUL-padding is not required due to alloc_etherdev
zero-allocating the buffer.

Get ahead of the game and fix all the -Wformat=2 noted warnings in the
intel drivers directory.
There are one set of i40e and iavf warnings I couldn't figure out how to
fix because the driver is already using vsnprintf without an explicit
"const char *" format string.
Tested with both gcc-12 and clang-15. I found gcc-12 runs clean after
this series but clang-15 is a little worried about the vsnprintf lines.

Fix -Wformat-truncated warnings to complete the intel directories' W=1
clean efforts. The W=1 recently got enhanced with a few new flags and
this brought up some new warnings.
Switch to using kasprintf() when possible so we always allocate the
right length strings.

The mii_bus API conversion to read_c45() and write_c45() did not cover
the mdio-mux driver before read() and write() were made C22-only.
This broke arch/arm64/boot/dts/freescale/fsl-ls1028a-qds-13bb.dtso.
The -EOPNOTSUPP from mdiobus_c45_read() is transformed by
get_phy_c45_devs_in_pkg() into -EIO, is further propagated to
of_mdiobus_register() and this makes the mdio-mux driver fail to probe
the entire child buses, not just the PHYs that cause access errors.
Fix the regression by introducing special c45 read and write accessors
to mdio-mux which forward the operation to the parent MDIO bus.

The affected code's purpose is to truncate strings that are too long

The lengths have been carefully calculated and as such this has decayed
to a simple byte copy from one buffer to another -- let's use memcpy().

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We expect led->name to be NUL-terminated based on the presence of a
manual NUL-byte assignment.
This NUL-byte assignment was added in Commit daf9669bea30aa22 ("ath5k:
ensure led name is null terminated"). If strscpy() had existed and had
been used back when this code was written then potential bugs and the
need to manually NUL-terminate could have been avoided. Since we now
have the technology, let's use it :)
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding. If NUL-padding is required let's opt
for strscpy_pad().

The capabilities for the EHT mesh are generated from the capabilities

capabilities and not the one which are specific for mesh.
Capabilities which requires infrastructure setup with a main STA(AP)
controlling operations are not needed for mesh and hence remove these
capabilities from the list.

Saeed Mahameed says:
====================
mlx5-updates-2023-10-10
1) Adham Faris, Increase max supported channels number to 256
2) Leon Romanovsky, Allow IPsec soft/hard limits in bytes
3) Shay Drory, Replace global mlx5_intf_lock with
HCA devcom component lock
4) Wei Zhang, Optimize SF creation flow
During SF creation, HCA state gets changed from INVALID to
IN_USE step by step. Accordingly, FW sends vhca event to
driver to inform about this state change asynchronously.
Each vhca event is critical because all related SW/FW
operations are triggered by it.
Currently there is only a single mlx5 general event handler
which not only handles vhca event but many other events.
This incurs huge bottleneck because all events are forced
to be handled in serial manner.
Moreover, all SFs share same table_lock which inevitably
impacts each other when they are created in parallel.
This series will solve this issue by:
1. A dedicated vhca event handler is introduced to eliminate
the mutual impact with other mlx5 events.
2. Max FW threads work queues are employed in the vhca event
handler to fully utilize FW capability.
3. Redesign SF active work logic to completely remove
table_lock.
With above optimization, SF creation time is reduced by 25%,
i.e. from 80s to 60s when creating 100 SFs.
Patches summary:
Patch 1 - implement dedicated vhca event handler with max FW
cmd threads of work queues.
Patch 2 - remove table_lock by redesigning SF active work
logic.

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We expect both hi.data.modename and hi.data.drivername to be
NUL-terminated based on its usage with sprintf:
| sprintf(hi.data.modename, "%sclk,%smodem,fclk=%d,bps=%d%s",
| bc->cfg.intclk ? "int" : "ext",
| bc->cfg.extmodem ? "ext" : "int", bc->cfg.fclk, bc->cfg.bps,
| bc->cfg.loopback ? ",loopback" : "");
Note that this data is copied out to userspace with:
| if (copy_to_user(data, &hi, sizeof(hi)))
... however, the data was also copied FROM the user here:
| if (copy_from_user(&hi, data, sizeof(hi)))
Considering the above, a suitable replacement is strscpy_pad() as it
guarantees NUL-termination on the destination buffer while also
NUL-padding (which is good+wanted behavior when copying data to
userspace).
