Strncpy is now deprecated.
The buffer destination is not required to be NULL-terminated, but we also
want to zero out the rest of the buffer as it is already done in other
places.

Let's not move poisoned extents unnecessarily, since we can't guard
against introducing more bitrot.

Now, if an extent is poisoned we can move it even if there was a
checksum error. We'll have to give it a new checksum, but the poison bit
means that userspace will still see the appropriate error when they try
to read it.

Copygc needs to be able to move extents that have bitrotted. We don't
want to delete them - in the future we'll have an API for "read me the
data even if there's checksum errors", and in general we don't want to
delete anything unless the user asks us to.
That will require writing it with a new checksum, which means we can't
forget that there was a checksum error so we return the correct error to
userspace.
Rebalance also wants to skip bad extents; we can now use the poison flag
for that.
This is currently disabled by default, as we want read fua support so
that we can distinguish between transient and permanent errors from the
device. It may be enabled with the module parameter:
poison_extents_on_checksum_error

If the extent we're reading from changes, due to be being overwritten or
moved (possibly partially) - we need to reset bch_io_failures so that we
don't accidentally mark a new extent as poisoned prematurely.
This means we have to separately track (in the retry path) the extent we
previously read from.

Check for mismatches between casefold dirents and casefold directories.
A mismatch will cause lookups to fail, as we'll be doing the lookup with

net: phy: Add support for new Aeonsemi PHYs
Add support for new Aeonsemi 10G C45 PHYs. These PHYs intergate an IPC
to setup some configuration and require special handling to sync with
the parity bit. The parity bit is a way the IPC use to follow correct
order of command sent.
Supported PHYs AS21011JB1, AS21011PB1, AS21010JB1, AS21010PB1,
AS21511JB1, AS21511PB1, AS21510JB1, AS21510PB1, AS21210JB1,
AS21210PB1 that all register with the PHY ID 0x7500 0x7500
before the firmware is loaded.
The big special thing about this PHY is that it does provide
a generic PHY ID in C45 register that change to the correct one
one the firmware is loaded.
In practice:
- MMD 0x7 ID 0x7500 0x9410 -> FW LOAD -> ID 0x7500 0x9422
To handle this, we operate on .match_phy_device where
we check the PHY ID, if the ID match the generic one,
we load the firmware and we return 0 (PHY driver doesn't
match). Then PHY core will try the next PHY driver in the list
and this time the PHY is correctly filled in and we register
for it.
To help in the matching and not modify part of the PHY device
struct, .match_phy_device is extended to provide also the
current phy_driver is trying to match for. This add the
extra benefits that some other PHY can simplify their
.match_phy_device OP.

Add support for Aeonsemi AS21xxx 10G C45 PHYs. These PHYs integrate
an IPC to setup some configuration and require special handling to
sync with the parity bit. The parity bit is a way the IPC use to

AS21210PB1 that all register with the PHY ID 0x7500 0x7510
before the firmware is loaded.
They all support up to 5 LEDs with various HW mode supported.
While implementing it was found some strange coincidence with using the
same logic for implementing C22 in MMD regs in Broadcom PHYs.

Introduce new API, genphy_match_phy_device(), to provide a way to check
to match a PHY driver for a PHY device based on the info stored in the
PHY device struct.
The function generalize the logic used in phy_bus_match() to check the
PHY ID whether if C45 or C22 ID should be used for matching.
This is useful for custom .match_phy_device function that wants to use
the generic logic under some condition. (example a PHY is already setup
and provide the correct PHY ID)

Pass PHY driver pointer to .match_phy_device OP in addition to phydev.
Having access to the PHY driver struct might be useful to check the
PHY ID of the driver is being matched for in case the PHY ID scanned in
the phydev is not consistent.
A scenario for this is a PHY that change PHY ID after a firmware is
loaded, in such case, the PHY ID stored in PHY device struct is not
valid anymore and PHY will manually scan the ID in the match_phy_device
function.
Having the PHY driver info is also useful for those PHY driver that
implement multiple simple .match_phy_device OP to match specific MMD PHY
ID. With this extra info if the parsing logic is the same, the matching
function can be generalized by using the phy_id in the PHY driver
instead of hardcoding.
Rust wrapper callback is updated to align to the new match_phy_device
arguments.

If the driver reset fails, it may not work properly.
Therefore, the ndo.open() operation should be rejected.
In this patch, the driver calls netif_device_detach()
before the reset and calls netif_device_attach()
after the reset succeeds. If the reset fails,
netif_device_attach() is not called. Therefore,
netdev does not present and cannot be opened.
If reset fails, only the PCI reset (via sysfs)
can be used to attempt recovery.

net: faster and simpler CRC32C computation
Update networking code that computes the CRC32C of packets to just call
crc32c() without unnecessary abstraction layers. The result is faster
and simpler code.
Patches 1-7 add skb_crc32c() and remove the overly-abstracted and
inefficient __skb_checksum().
Patches 8-10 replace skb_copy_and_hash_datagram_iter() with
skb_copy_and_crc32c_datagram_iter(), eliminating the unnecessary use of
the crypto layer. This unblocks the conversion of nvme-tcp to call
crc32c() directly instead of using the crypto layer, which patch 9 does.

Now that the crc32c() library function directly takes advantage of
architecture-specific optimizations and there also now exists a function
skb_copy_and_crc32c_datagram_iter(), it is unnecessary to go through the

it also improves performance due to eliminating the crypto API overhead.

Since skb_copy_and_hash_datagram_iter() is used only with CRC32C, the
crypto_ahash abstraction provides no value. Add
skb_copy_and_crc32c_datagram_iter() which just calls crc32c() directly.
This is faster and simpler. It also doesn't have the weird dependency
issue where skb_copy_and_hash_datagram_iter() depends on
CONFIG_CRYPTO_HASH=y without that being expressed explicitly in the
kconfig (presumably because it was too heavyweight for NET to select).
The new function is conditional on the hidden boolean symbol NET_CRC32C,
which selects CRC32. So it gets compiled only when something that
actually needs CRC32C packet checksums is enabled, it has no implicit
dependency, and it doesn't depend on the heavyweight crypto layer.

Add skb_crc32c(), which calculates the CRC32C of a sk_buff. It will
replace __skb_checksum(), which unnecessarily supports arbitrary
checksums. Compared to __skb_checksum(), skb_crc32c():
- Uses the correct type for CRC32C values (u32, not __wsum).
- Does not require the caller to provide a skb_checksum_ops struct.
- Is faster because it does not use indirect calls and does not use
the very slow crc32c_combine().
According to commit 2817a336d4d5 ("net: skb_checksum: allow custom
update/combine for walking skb") which added __skb_checksum(), the
original motivation for the abstraction layer was to avoid code
duplication for CRC32C and other checksums in the future. However:
- No additional checksums showed up after CRC32C. __skb_checksum()
is only used with the "regular" net checksum and CRC32C.
- Indirect calls are expensive. Commit 2544af0344ba ("net: avoid
indirect calls in L4 checksum calculation") worked around this
using the INDIRECT_CALL_1 macro. But that only avoided the indirect
call for the net checksum, and at the cost of an extra branch.
- The checksums use different types (__wsum and u32), causing casts
to be needed.
- It made the checksums of fragments be combined (rather than
chained) for both checksums, despite this being highly
counterproductive for CRC32C due to how slow crc32c_combine() is.
This can clearly be seen in commit 4c2f24549644 ("sctp: linearize
early if it's not GSO") which tried to work around this performance
bug. With a dedicated function for each checksum, we can instead
just use the proper strategy for each checksum.
As shown by the following tables, the new function skb_crc32c() is
faster than __skb_checksum(), with the improvement varying greatly from
5% to 2500% depending on the case. The largest improvements come from
fragmented packets, mainly due to eliminating the inefficient
crc32c_combine(). But linear packets are improved too, especially
shorter ones, mainly due to eliminating indirect calls. These
benchmarks were done on AMD Zen 5. On that CPU, Linux uses IBRS instead
of retpoline; an even greater improvement might be seen with retpoline:

However, this update fails because ah->regd_updated was already set to true

added.
To resolve this, reset ah->regd_updated before calling
ath12k_reg_handle_chan_list() to ensure the update proceeds correctly.

Commit 4c546023d71a ("wifi: ath12k: update regulatory rules when interface
added"), introduced a call to ath12k_reg_handle_chan_list() during
interface addition to update the regulatory domain based on the interface
type. While this works initially, subsequent updates (e.g., after an
interface delete/re-add cycle) fail because ah->regd_updated is never
reset.
To address this, reset ah->regd_updated before calling
ath12k_reg_handle_chan_list() to allow the update to proceed.
However, this change exposes another issue: a timeout occurs when waiting
for the 11D scan to complete, as seen in the log:
ath12k_pci 0000:05:00.0: failed to receive 11d scan complete: timed out
This happens because during interface down, ar->state_11d is set to
ATH12K_11D_PREPARING, and during interface up, the host waits for
ar->completed_11d_scan even though the scan hasn't started yet.
Fix this by updating the wait condition to check for ATH12K_11D_RUNNING,
which is the only state where a scan complete event is expected.

In the current implementation of ath12k_regd_update(), the ah->regd_updated
flag is used to ensure that the regulatory domain is updated only once per
radio. During MAC registration, this function is called to push the default
regulatory domain to cfg80211. At that point, the hardware state is not on
and hence ah->regd_updated remains false.
However, after commit 4c546023d71a ("wifi: ath12k: update regulatory rules
when interface added"), ath12k_reg_handle_chan_list() is invoked when an
interface is added, which in turn calls ath12k_regd_update(). By this time,
hardware state is on and consecutively ah->regd_updated becomes true.
Later, when the 11D scan completes and a new regulatory domain is received
from the firmware, the host attempts to update cfg80211 again via
ath12k_regd_update(). But since ah->regd_updated is already true, the
update is skipped.
>From the user's perspective, this results in a failure to connect to 6 GHz
APs, as the default regulatory domain (the only one pushed to cfg80211)
does not include 6 GHz support.
To resolve this, reset the ah->regd_updated flag when handling the 11D
regulatory domain update.

In store_scaling_setspeed(), sscanf is still used to read to sysfs.
Newer kstrtox provide more features including overflow protection,
better errorhandling and allows for other systems of numeration. It
is therefore better to update sscanf() to kstrtouint().

Some systems expose HD-Audio controllers via objects in the ACPI tables
which encapsulate the controller's interrupt and the base address for the
HDA registers in an ACPI _CRS object, for example, as listed in this ACPI
table dump excerpt:
Device (HDA0)
{
Name (_HID, "NVDA2014") // _HID: Hardware ID
...
Name (_CRS, ResourceTemplate ()
// _CRS: Current Resource Settings
{
Memory32Fixed (ReadWrite,
0x36078000, // Address Base
0x00008000, // Address Length
)
Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive,
,, )
{
0x0000021E,
}
})
}
Add support for HDA controllers discovered through ACPI, including support
for some platforms which expose such HDA controllers on NVIDIA SoCs. This
is done with a new driver which uses existing infrastructure for extracting
resource information from _CRS objects and plumbs the parsed resource
information through to the existing HDA infrastructure to enable HD-Audio
functionality on such devices.
Although this driver is in the sound/pci/hda/ directory, it targets devices
which are not actually enumerated on the PCI bus. This is because it
depends upon the Intel "Azalia" infrastructure which has traditionally been
usedvfor PCI-based devices.

TC uses all possible sub-message formats:
- nested attrs
- fixed headers + nested attrs
- fixed headers
- empty
Nested attrs are already supported for rt-link. Add support
for remaining 3. The empty and fixed headers ones are fairly
trivial, we can fake a Binary or Flags type instead of a Nest.
For fixed headers + nest we need to teach nest parsing and
nest put to handle fixed headers.
