net: stmmac: use correct PPS input indexing
The stmmac can have 0 to 4 auxiliary snapshot in channels, which can be
used for capturing external triggers with respect to the eqos PTP timer.
Previously when enabling the auxiliary snapshot, an invalid request was
written to the hardware register, except for the Intel variant of this
driver, where the only snapshot available was hardcoded.
Patch 1 of this series cleans up the debug netdev_dbg message indicating
the auxiliary snapshot being {en,dis}abled. No functional changes here
Patch 2 of this series writes the correct PPS input indexing to the
hardware registers instead of a previously used fixed value
Patch 3 of this series removes a field member from plat_stmmacnet_data
that is no longer needed
Patch 4 of this series prepares Patch 5 by protecting the snapshot
enabled flag by the aux_ts_lock mutex
Patch 5 of this series adds a temporary workaround, since at the moment
the driver can handle only one single auxiliary snapshot at a time.
Previously the driver silently dropped the previous configuration and
enabled the new one. Now, if a snapshot is already enabled and userspace
tries to enable another without previously disabling the snapshot currently
enabled: issue a netdev_err and return an errorcode indicating the device is
busy.
This series is a "never worked, doesn't hurt anyone" touchup to the PPS
capture for non-intel variants of the dwmac driver.

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
is active and return with an error. So we have to move the change of the
plat->flags that tracks if external timestamping is enabled after that
check.
Prepare for this change and move the plat->flags change into the mutex
and the if (on).

plat_stmmacenet_data::ext_snapshot_num
Do not store bitmask for enabling AUX_SNAPSHOT0. The previous commit
("net: stmmac: fix PPS capture input index") takes care of calculating
the proper bit mask from the request data's extts.index field, which is
0 if not explicitly specified otherwise.

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

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.

netfilter: updates for net
First patch, from Phil Sutter, reduces number of audit notifications
when userspace requests to re-set stateful objects.
This change also comes with a selftest update.
Second patch, also from Phil, moves the nftables audit selftest
to its own netns to avoid interference with the init netns.
Third patch, from Pablo Neira, fixes an inconsistency with the "rbtree"
set backend: When set element X has expired, a request to delete element
X should fail (like with all other backends).
Finally, patch four, also from Pablo, reverts a recent attempt to speed
up abort of a large pending update with the "pipapo" set backend.
It could cause stray references to remain in the set, which then
results in a double-free.

Intel Wired LAN Driver Updates 2023-10-17
This series contains cleanups for all the Intel drivers relating to their
use of format specifiers and the use of strncpy.
Jesse fixes various -Wformat warnings across all the Intel networking,
including various cases where a "%s" string format specifier is preferred,
and using kasprintf instead of snprintf.
Justin replaces all of the uses of the now deprecated strncpy with a more
modern string function, primarily strscpy.

`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.

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.

Christian Theune says:
I upgraded from 6.1.38 to 6.1.55 this morning and it broke my traffic shaping script,
leaving me with a non-functional uplink on a remote router.
A 'rt' curve cannot be used as a inner curve (parent class), but we were
allowing such configurations since the qdisc was introduced. Such
configurations would trigger a UAF as Budimir explains:
The parent will have vttree_insert() called on it in init_vf(),
but will not have vttree_remove() called on it in update_vf()
because it does not have the HFSC_FSC flag set.
The qdisc always assumes that inner classes have the HFSC_FSC flag set.
This is by design as it doesn't make sense 'qdisc wise' for an 'rt'
curve to be an inner curve.
Budimir's original patch disallows users to add classes with a 'rt'
parent, but this is too strict as it breaks users that have been using
'rt' as a inner class. Another approach, taken by this patch, is to
upgrade the inner 'rt' into a 'sc', warning the user in the process.
It avoids the UAF reported by Budimir while also being more permissive
to bad scripts/users/code using 'rt' as a inner class.
Users checking the `tc class ls [...]` or `tc class get [...]` dumps would
observe the curve change and are potentially breaking with this change.

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.

In commit 75eefc6c59fd ("tcp: tsq: add a shortcut in tcp_small_queue_check()")
we allowed to send an skb regardless of TSQ limits being hit if rtx queue
was empty or had a single skb, in order to better fill the pipe
when/if TX completions were slow.
Then later, commit 75c119afe14f ("tcp: implement rb-tree based
retransmit queue") accidentally removed the special case for
one skb in rtx queue.
Stefan Wahren reported a regression in single TCP flow throughput
using a 100Mbit fec link, starting from commit 65466904b015 ("tcp: adjust
TSO packet sizes based on min_rtt"). This last commit only made the
regression more visible, because it locked the TCP flow on a particular
behavior where TSQ prevented two skbs being pushed downstream,
adding silences on the wire between each TSO packet.
Many thanks to Stefan for his invaluable help !

fine as it added also a definition of __NR_seccomp for 64-bit. But it

Assume that caller's 'to' offset really represents an upper boundary for
the pattern search, so patterns extending past this offset are to be
rejected.
The old behaviour also was kind of inconsistent when it comes to
fragmentation (or otherwise non-linear skbs): If the pattern started in
between 'to' and 'from' offsets but extended to the next fragment, it
was not found if 'to' offset was still within the current fragment.
Test the new behaviour in a kselftest using iptables' string match.

Furthermore, when shutting down with `poweroff` and modem attached, the
system rebooted instead of powering down as expected. The modem works
again only after power cycling.

====================
netfilter next pull request 2023-10-18
This series contains initial netfilter skb drop_reason support, from
myself.
First few patches fix up a few spots to make sure we won't trip
when followup patches embed error numbers in the upper bits
(we already do this in some places).
Then, nftables and bridge netfilter get converted to call kfree_skb_reason
directly to let tooling pinpoint exact location of packet drops,
rather than the existing NF_DROP catchall in nf_hook_slow().
I would like to eventually convert all netfilter modules, but as some
callers cannot deal with NF_STOLEN (notably act_ct), more preparation
work is needed for this.
Last patch gets rid of an ugly 'de-const' cast in nftables.
