`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
NUL-padding is not required as the buffer is already memset to 0:
| memset(adapter->fw_version, 0, 32);
Note that another usage of strscpy exists on the same buffer:
| strscpy((char *)adapter->fw_version, "N/A", sizeof(adapter->fw_version));
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.

[1] and as such we should prefer more robust and less ambiguous string
interfaces.
ethtool_sprintf() is designed specifically for get_strings() usage.
Let's replace strncpy in favor of this more robust and easier to
understand interface.
Also, while we're here, let's change memcpy() over to ethtool_sprintf()
for consistency.

struct_size()
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
While there, use struct_size() helper, instead of the open-coded
version, to calculate the size for the allocation of the whole
flexible structure, including of course, the flexible-array member.
This code was found with the help of Coccinelle, and audited and
fixed manually.

Currently, clock configuration is spread throughout the driver and
partially duplicated for the STM32MP1 and STM32 MCU variants. This makes
it difficult to keep track of which clocks need to be enabled or disabled
in various scenarios.
This patch adds symmetric stm32_dwmac_clk_enable/disable() functions
that handle all clock configuration, including quirks required while
suspending or resuming. syscfg_clk and clk_eth_ck are not present on
STM32 MCUs, but it is fine to try to configure them anyway since NULL
clocks are ignored.

====================
Extend VXLAN driver to support FDB flushing
The merge commit 92716869375b ("Merge branch 'br-flush-filtering'") added
support for FDB flushing in bridge driver. Extend VXLAN driver to support
FDB flushing also. Add support for filtering by fields which are relevant
for VXLAN FDBs:
* Source VNI
* Nexthop ID
* 'router' flag
* Destination VNI
* Destination Port
* Destination IP
Without this set, flush for VXLAN device fails:
$ bridge fdb flush dev vx10
RTNETLINK answers: Operation not supported
With this set, such flush works with the relevant arguments, for example:
$ bridge fdb flush dev vx10 vni 5000 dst 193.2.2.1
< flush all vx10 entries with VNI 5000 and destination IP 193.2.2.1>
Some preparations are required, handle them before adding flushing support
in VXLAN driver. See more details in commit messages.
Patch set overview:
Patch #1 prepares flush policy to be used by VXLAN driver
Patches #2-#3 are preparations in VXLAN driver
Patch #4 adds an initial support for flushing in VXLAN driver
Patches #5-#9 add support for filtering by several attributes
Patch #10 adds a test for FDB flush with VXLAN
Patch #11 extends the test to check FDB flush with bridge

Add support for flush VXLAN FDB entries by destination IP. FDB entry is
stored as {MAC, SRC_VNI} + remote. The destination IP is an attribute of
the remote. For multicast entries, the VXLAN driver stores a linked list
of remotes for a given key.
In user space, each remote is represented as a separate entry, so when
flush is sent with filter of 'destination IP', flush only the match
remotes. In case that there are no additional remotes, destroy the entry.
For example, the following are stored as one entry with several remotes:
$ bridge fdb show dev vx10
00:00:00:00:00:00 dst 192.1.1.3 self permanent
00:00:00:00:00:00 dst 192.1.1.1 self permanent
00:00:00:00:00:00 dst 192.1.1.2 self permanent
00:00:00:00:00:00 dst 192.1.1.1 vni 1000 self permanent
When user flush by destination IP x, only the relevant remotes will be
flushed:
$ bridge fdb flush dev vx10 dst 192.1.1.1
$ bridge fdb show dev vx10
00:00:00:00:00:00 dst 192.1.1.3 self permanent

In this commit, add support for flushing with state and flags, which are

Note that bridge driver supports 'NTF_USE' flag, but there is no point to
support this flag for flushing as it is ignored when flags are stored.
'NTF_STICKY' is not relevant for VXLAN driver.
'NTF_ROUTER' is not supported in bridge driver for flush as it is not

Currently, the function vxlan_flush() does not flush the default FDB entry
(an entry with all_zeros_mac and default VNI), as it is deleted at
vxlan_uninit(). When this function will be used for flushing FDB entries
from user space, it will have to flush also the default entry in case that
other parameters match (e.g., VNI, flags).
Extend 'struct vxlan_fdb_flush_desc' to include an indication whether
the default entry should be flushed or not. The default value (false)
indicates to flush it, adjust all the existing callers to set
'.ignore_default_entry' to true, so the current behavior will not be
changed.

The merge commit 92716869375b ("Merge branch 'br-flush-filtering'")
added support for FDB flushing in bridge driver. The following patches
will extend VXLAN driver to support FDB flushing as well. The netlink
message for bulk delete is shared between the drivers. With the existing
implementation, there is no way to prevent user from flushing with
attributes that are not supported per driver. For example, when VNI will
be added, user will not get an error for flush FDB entries in bridge
with VNI, although this attribute is not relevant for bridge.
As preparation for support of FDB flush in VXLAN driver, move the policy
to be handled in bridge driver, later a new policy for VXLAN will be
added in VXLAN driver. Do not pass 'vid' as part of ndo_fdb_del_bulk(),
as this field is relevant only for bridge.

Fixes for v6.6-rc5
- fix to not reset the PHY everytime we start link training but only
do it if link training fails. Without this, the PLL unlocked
interrupt fires causing "Unexpected DP AUX IRQ 0x01000000 when
not busy" spam in the logs since last 2-3 cycles
- correct the highest bank bit to match downstream device tree for
msm8998
- skip the video mode wait if the timing engine is not enabled. This
was introduced after pre_enable flag for DSI video mode panels
where we would end up waiting for the video mode done interrupt
even before enabling timing engine causing error spam and long
bootup times.
- check the correct return code of irq_of_parse_and_map() in DSI code
- avoid overflow issues in the dpu bandwidth calculation . This was
exposed for high resolution displays and a critical fix to avoid
atomic_check failure
- minor fix to add new lines in DP print messages.
- Fix to fail atomic_check() if the resolution exceeds max mdp clk.
This leads to underflow otherwise if we try to allow that frame.

This reverts commit 92e24e0e57f72e06c2df87116557331fd2d4dda2.
While the patch itself is correct, it uncovered an issue with fallback
to PS/2 mode, where we were leaving psmouse->fast_reconnect handler set
to psmouse_smbus_reconnect(), which caused crashes.
While discussing various approaches to fix the issue it was noted that
this patch ass undesired delay in the "fast" resume path of PS/2 device,
and it would be better to actually use "reset_delay" option defined in
struct rmi_device_platform_data and have RMI code handle it for SMBus
transport as well. So this patch is being reverted to deal with crashes
and a better solution will be merged shortly.

Commit df8fc4e934c1 ("kbuild: Enable -fstrict-flex-arrays=3") enabled
'-fstrict-flex-arrays=3' globally, but bindgen does not recognized this
compiler option, triggering the following build error:
error: unknown argument: '-fstrict-flex-arrays=3', err: true
[ Miguel: Commit df8fc4e934c1 ("kbuild: Enable -fstrict-flex-arrays=3")
did it so only conditionally (i.e. only if the C compiler supports
it). This explains what Andrea was seeing: he was compiling with a
modern enough GCC, which enables the option, but with an old enough
Clang. Andrea confirmed this was the case: he was using Clang 14 with
GCC 13; and that Clang 15 worked for him.
While it is possible to construct code (see mailing list for an
example I came up with) where this could break, it is fairly
contrived, and anyway GCC-built kernels with Rust enabled should
only be used for experimentation until we get support for
`rustc_codegen_gcc` and/or GCC Rust. So let's add this for the
time being in case it helps somebody. ]
Add '-fstrict-flex-arrays' to the list of cflags that should be ignored
by bindgen.

workqueue_apply_unbound_cpumask()
Commit 5c0338c68706 ("workqueue: restore WQ_UNBOUND/max_active==1
to be ordered") enabled implicit ordered attribute to be added to
WQ_UNBOUND workqueues with max_active of 1. This prevented the changing
of attributes to these workqueues leading to fix commit 0a94efb5acbb
("workqueue: implicit ordered attribute should be overridable").
However, workqueue_apply_unbound_cpumask() was not updated at that time.
So sysfs changes to wq_unbound_cpumask has no effect on WQ_UNBOUND
workqueues with implicit ordered attribute. Since not all WQ_UNBOUND
workqueues are visible on sysfs, we are not able to make all the
necessary cpumask changes even if we iterates all the workqueue cpumasks
in sysfs and changing them one by one.
Fix this problem by applying the corresponding change made
to apply_workqueue_attrs_locked() in the fix commit to
workqueue_apply_unbound_cpumask().

The ABI mandates that the %esp register must be a multiple of 16 when
executing a 'call' instruction.
Commit 2ab446336b17 ("tools/nolibc: i386: shrink _start with _start_c")
simplified the _start function, but it didn't take care of the %esp
alignment, causing SIGSEGV on SSE and AVX programs that use aligned move
instruction (e.g., movdqa, movaps, and vmovdqa).
The 'and $-16, %esp' aligns the %esp at a multiple of 16. Then 'push
%eax' will subtract the %esp by 4; thus, it breaks the 16-byte
alignment. Make sure the %esp is correctly aligned after the push by
subtracting 12 before the push.
Extra:
Add 'add $12, %esp' before the 'and $-16, %esp' to avoid over-estimating
for particular cases as suggested by Willy.
A test program to validate the %esp alignment on _start can be found at:
