The register fields of BSS color map and valid bit are in the same register
for existing chips, but coming WiFi 7 chips define another register to
set valid bit, so add a field to chip_info to reuse the code.

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.

Sometimes firmware may enter strange state or infinite
loop due to unknown bug, and then it will lead critical
function fail, such as sending H2C command or changing
power mode. In these abnormal states, we add more debug
information, including hardware register status, to help
further investigation.

The coming dump function for FW malfunction will add a function to
dump registers to reflect status. However, if we are not debugging
the mechanism, we don't print anything, so avoid reading registers by
checking debug mask to reduce IO.

Remove set but otherwise unused 'sleep_ms', 'last_action', 'state'
and 'last_slept' members of 'struct rtl_ps_ctl' (these seems to be
a leftovers from some older code) and adjust 'rtl_swlps_wq_callback()'

This is a kconfig warning in a randconfig when CONFIG_PCI is not set:
WARNING: unmet direct dependencies detected for SSB_EMBEDDED
Depends on [n]: SSB [=y] && SSB_DRIVER_MIPS [=y] && SSB_PCICORE_HOSTMODE [=n]
Selected by [y]:

This is caused by arch/mips/bcm47xx/Kconfig's symbol BCM47XX_SSB

Florian Westphal says:
====================
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.

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

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
failed to do so for 32-bit as instead of ifndef, ifdef was used.

It may happen that the work to destroy a queue
(for example nvmet_tcp_release_queue_work()) is started while
an auth-send or auth-receive command is still completing.
nvmet_sq_destroy() will block, waiting for all the references
to the sq to be dropped, the last reference is then
dropped when nvmet_req_complete() is called.
When this happens, both nvmet_sq_destroy() and
nvmet_execute_auth_send()/_receive() will free the dhchap pointers by
calling nvmet_auth_sq_free().
Since there isn't any lock, the two threads may race against each other,
causing double frees and memory corruptions, as reported by KASAN.

Users complained about OOM errors during fork without triggering
compaction. This can be fixed by modifying the flags used in
mas_expected_entries() so that the compaction will be triggered in low
memory situations. Since mas_expected_entries() is only used during fork,
the extra argument does not need to be passed through.
Additionally, the two test_maple_tree test cases and one benchmark test
were altered to use the correct locking type so that allocations would not
trigger sleeping and thus fail. Testing was completed with lockdep atomic
sleep detection.
The additional locking change requires rwsem support additions to the
tools/ directory through the use of pthreads pthread_rwlock_t. With this
change test_maple_tree works in userspace, as a module, and in-kernel.
Users may notice that the system gave up early on attempting to start new
processes instead of attempting to reclaim memory.

I no longer work for BayLibre but many DT bindings have my BL address in
the maintainers entries. Map it to the email address I use for kernel
development.

DAMON_SYSFS can receive DAMOS tried regions update request while kdamond
is already out of the main loop and before_terminate callback
(damon_sysfs_before_terminate() in this case) is not yet called. And
damon_sysfs_handle_cmd() can further be finished before the callback is
invoked. Then, damon_sysfs_before_terminate() unlocks damon_sysfs_lock,
which is not locked by anyone. This happens because the callback function
assumes damon_sysfs_cmd_request_callback() should be called before it.
Check if the assumption was true before doing the unlock, to avoid this
problem.

On arm64, building with CONFIG_KASAN_HW_TAGS now causes a compile-time
error:
mm/kasan/report.c: In function 'kasan_non_canonical_hook':
mm/kasan/report.c:637:20: error: 'KASAN_SHADOW_OFFSET' undeclared (first use in this function)
637 | if (addr < KASAN_SHADOW_OFFSET)
| ^~~~~~~~~~~~~~~~~~~
mm/kasan/report.c:637:20: note: each undeclared identifier is reported only once for each function it appears in
mm/kasan/report.c:640:77: error: expected expression before ';' token
640 | orig_addr = (addr - KASAN_SHADOW_OFFSET) << KASAN_SHADOW_SCALE_SHIFT;
This was caused by removing the dependency on CONFIG_KASAN_INLINE that
used to prevent this from happening. Use the more specific dependency
on KASAN_SW_TAGS || KASAN_GENERIC to only ignore the function for hwasan
mode.
