Pull networking fixes from Jakub Kicinski:
"Including fixes from bluetooth, netfilter, WiFi.
Feels like an up-tick in regression fixes, mostly for older releases.
The hfsc fix, tcp_disconnect() and Intel WWAN fixes stand out as
fairly clear-cut user reported regressions. The mlx5 DMA bug was
causing strife for 390x folks. The fixes themselves are not
particularly scary, tho. No open investigations / outstanding reports
at the time of writing.
Current release - regressions:
- eth: mlx5: perform DMA operations in the right locations, make
devices usable on s390x, again
- sched: sch_hfsc: upgrade 'rt' to 'sc' when it becomes a inner
curve, previous fix of rejecting invalid config broke some scripts
- rfkill: reduce data->mtx scope in rfkill_fop_open, avoid deadlock
- revert "ethtool: Fix mod state of verbose no_mask bitset", needs
more work
Current release - new code bugs:
- tcp: fix listen() warning with v4-mapped-v6 address
Previous releases - regressions:
- tcp: allow tcp_disconnect() again when threads are waiting, it was
denied to plug a constant source of bugs but turns out .NET depends
on it
- eth: mlx5: fix double-free if buffer refill fails under OOM
- revert "net: wwan: iosm: enable runtime pm support for 7560", it's
causing regressions and the WWAN team at Intel disappeared
- tcp: tsq: relax tcp_small_queue_check() when rtx queue contains a
single skb, fix single-stream perf regression on some devices
Previous releases - always broken:
- Bluetooth:
- fix issues in legacy BR/EDR PIN code pairing
- correctly bounds check and pad HCI_MON_NEW_INDEX name
- netfilter:
- more fixes / follow ups for the large "commit protocol" rework,
which went in as a fix to 6.5
- fix null-derefs on netlink attrs which user may not pass in
- tcp: fix excessive TLP and RACK timeouts from HZ rounding (bless
Debian for keeping HZ=250 alive)
- net: more strict VIRTIO_NET_HDR_GSO_UDP_L4 validation, prevent
letting frankenstein UDP super-frames from getting into the stack
- net: fix interface altnames when ifc moves to a new namespace
- eth: qed: fix the size of the RX buffers

The bitmasks for EMAC_PORT_DISABLE and EMAC_PORT_FORWARD r30 commands are
wrong in the driver.
Update the bitmasks of these commands to the correct ones as used by the
ICSSG firmware. These bitmasks are backwards compatible and work with
any ICSSG firmware version.

Commit 8fce33317023 ("net: stmmac: Rework coalesce timer and fix
multi-queue races") decreased the TX coalesce timer from 40ms to 1ms.
This caused some performance regression on some target (regression was
reported at least on ipq806x) in the order of 600mbps dropping from
gigabit handling to only 200mbps.
The problem was identified in the TX timer getting armed too much time.
While this was fixed and improved in another commit, performance can be
improved even further by increasing the timer delay a bit moving from
1ms to 5ms.
The value is a good balance between battery saving by prevending too
much interrupt to be generated and permitting good performance for
internet oriented devices.

Move TX timer arm call after DMA interrupt is enabled again.
The TX timer arm function changed logic and now is skipped if a napi is
already scheduled. By moving the TX timer arm call after DMA is enabled,
we permit to correctly skip if a DMA interrupt has been fired and a napi
has been scheduled again.

There is currently a problem with the TX timer getting armed multiple
unnecessary times causing big performance regression on some device that
suffer from heavy handling of hrtimer rearm.
The use of the TX timer is an old implementation that predates the napi
implementation and the interrupt enable/disable handling.
Due to stmmac being a very old code, the TX timer was never evaluated
again with this new implementation and was kept there causing
performance regression. The performance regression started to appear
with kernel version 4.19 with 8fce33317023 ("net: stmmac: Rework coalesce
timer and fix multi-queue races") where the timer was reduced to 1ms
causing it to be armed 40 times more than before.
Decreasing the timer made the problem more present and caused the
regression in the other of 600-700mbps on some device (regression where
this was notice is ipq806x).
The problem is in the fact that handling the hrtimer on some target is
expensive and recent kernel made the timer armed much more times.
A solution that was proposed was reverting the hrtimer change and use
mod_timer but such solution would still hide the real problem in the
current implementation.
To fix the regression, apply some additional logic and skip arming the
timer when not needed.
Arm the timer ONLY if a napi is not already scheduled. Running the timer
is redundant since the same function (stmmac_tx_clean) will run in the
napi TX poll. Also try to cancel any timer if a napi is scheduled to
prevent redundant run of TX call.
With the following new logic the original performance are restored while
keeping using the hrtimer.

We currently have napi_if_scheduled_mark_missed that can be used to
check if napi is scheduled but that does more thing than simply checking
it and return a bool. Some driver already implement custom function to
check if napi is scheduled.
Drop these custom function and introduce napi_is_scheduled that simply
check if napi is scheduled atomically.
Update any driver and code that implement a similar check and instead
use this new helper.

'san_addr' and 'mac_fcoeq' members of struct iavf_mac_info are unused.
'type' is write-only. Delete all three.
The function iavf_set_mac_type that sets 'type' also checks if the PCI
vendor ID is Intel. This is unnecessary. Delete the whole function.
If in the future there's a need for the MAC type (or other PCI
ID-dependent data), I would prefer to use .driver_data in iavf_pci_tbl[]
for this purpose.

Even though the hardware theoretically supports up to 4 simultaneous
auxiliary snapshot capture channels, the stmmac driver does support only
a single channel to be active at a time.
Previously in case of a PTP_CLK_REQ_EXTTS request, previously active
auxiliary snapshot capture channels were silently dropped and the new
channel was activated.
Instead of silently changing the state for all consumers, log an error
and return -EBUSY if a channel is already in use in order to signal to
userspace to disable the currently active channel before enabling another one.

This is a preparation patch. The next patch will check if an external TS

setting the appropriate bits in the PTP_ACR bitfield.
Previously as of commit f4da56529da6 ("net: stmmac: Add support for

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

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.

`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.

[1] and as such we should prefer more robust and less ambiguous string
interfaces.
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.
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.

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

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.
