Pull networking fixes from Jakub Kicinski:
"Including fixes from Bluetooth, netfilter, BPF and WiFi.
I didn't collect precise data but feels like we've got a lot of 6.5
fixes here. WiFi fixes are most user-awaited.
Current release - regressions:
- Bluetooth: fix hci_link_tx_to RCU lock usage
Current release - new code bugs:
- bpf: mprog: fix maximum program check on mprog attachment
- eth: ti: icssg-prueth: fix signedness bug in prueth_init_tx_chns()
Previous releases - regressions:
- ipv6: tcp: add a missing nf_reset_ct() in 3WHS handling
- vringh: don't use vringh_kiov_advance() in vringh_iov_xfer(), it
doesn't handle zero length like we expected
- wifi:
- cfg80211: fix cqm_config access race, fix crashes with brcmfmac
- iwlwifi: mvm: handle PS changes in vif_cfg_changed
- mac80211: fix mesh id corruption on 32 bit systems
- mt76: mt76x02: fix MT76x0 external LNA gain handling
- Bluetooth: fix handling of HCI_QUIRK_STRICT_DUPLICATE_FILTER
- l2tp: fix handling of transhdrlen in __ip{,6}_append_data()
- dsa: mv88e6xxx: avoid EEPROM timeout when EEPROM is absent
- eth: stmmac: fix the incorrect parameter after refactoring
Previous releases - always broken:
- net: replace calls to sock->ops->connect() with kernel_connect(),
prevent address rewrite in kernel_bind(); otherwise BPF hooks may
modify arguments, unexpectedly to the caller
- tcp: fix delayed ACKs when reads and writes align with MSS
- bpf:
- verifier: unconditionally reset backtrack_state masks on global
func exit
- s390: let arch_prepare_bpf_trampoline return program size, fix
struct_ops offsets
- sockmap: fix accounting of available bytes in presence of PEEKs
- sockmap: reject sk_msg egress redirects to non-TCP sockets
- ipv4/fib: send netlink notify when delete source address routes
- ethtool: plca: fix width of reads when parsing netlink commands
- netfilter: nft_payload: rebuild vlan header on h_proto access
- Bluetooth: hci_codec: fix leaking memory of local_codecs
- eth: intel: ice: always add legacy 32byte RXDID in supported_rxdids
- eth: stmmac:
- dwmac-stm32: fix resume on STM32 MCU
- remove buggy and unneeded stmmac_poll_controller, depend on NAPI
- ibmveth: always recompute TCP pseudo-header checksum, fix use of
the driver with Open vSwitch
- wifi:
- rtw88: rtw8723d: fix MAC address offset in EEPROM
- mt76: fix lock dependency problem for wed_lock
- mwifiex: sanity check data reported by the device
- iwlwifi: ensure ack flag is properly cleared
- iwlwifi: mvm: fix a memory corruption due to bad pointer arithm
- iwlwifi: mvm: fix incorrect usage of scan API
Misc:
- wifi: mac80211: work around Cisco AP 9115 VHT MPDU length"

git://git.kernel.org/pub/scm/linux/kernel/git/overlayfs/vfs
Pull overlayfs fixes from Amir Goldstein:
- Fix for file reference leak regression
- Fix for NULL pointer deref regression
- Fixes for RCU-walk race regressions:
Two of the fixes were taken from Al's RCU pathwalk race fixes series
with his consent [1].
Note that unlike most of Al's series, these two patches are not about
racing with ->kill_sb() and they are also very recent regressions
from v6.5, so I think it's worth getting them into v6.5.y.
There is also a fix for an RCU pathwalk race with ->kill_sb(), which
may have been solved in vfs generic code as you suggested, but it
also rids overlayfs from a nasty hack, so I think it's worth anyway.

This patch drops id 0 limitation in mptcp_nl_cmd_sf_create() to allow
creating additional subflows with the local addr ID 0.
There is no reason not to allow additional subflows from this local
address: we should be able to create new subflows from the initial
endpoint. This limitation was breaking fullmesh support from userspace.

The delegated action infrastructure is prone to the following
race: different CPUs can try to schedule different delegated
actions on the same subflow at the same time.
Each of them will check different bits via mptcp_subflow_delegate(),
and will try to schedule the action on the related per-cpu napi
instance.
Depending on the timing, both can observe an empty delegated list
node, causing the same entry to be added simultaneously on two different
lists.
The root cause is that the delegated actions infra does not provide
a single synchronization point. Address the issue reserving an additional
bit to mark the subflow as scheduled for delegation. Acquiring such bit
guarantee the caller to own the delegated list node, and being able to
safely schedule the subflow.
Clear such bit only when the subflow scheduling is completed, ensuring
proper barrier in place.
Additionally swap the meaning of the delegated_action bitmask, to allow
the usage of the existing helper to set multiple bit at once.

Similarly as for ice driver [1] there are also circular header
dependencies in i40e driver:
i40e.h -> i40e_virtchnl_pf.h -> i40e.h
Another issue is that i40e header files does not contain their own
dependencies on other header files (both private and standard) so their
inclusion in .c file require to add these deps in certain order to
that .c file to make it compilable.
Fix both issues by removal the mentioned circular dependency, by filling
i40e headers with their dependencies so they can be placed anywhere in
a source code. Additionally remove bunch of includes from i40e.h super
header file that are not necessary and include i40e.h only in .c files
that really require it.

While searching for possible refactor of napi_schedule_prep and
__napi_schedule it was notice that the mtk eth driver disable the
interrupt for rx and tx AFTER napi is scheduled.
While this is a very hard to repro case it might happen to have
situation where the interrupt is disabled and never enabled again as the
napi completes and the interrupt is enabled before.
This is caused by the fact that a napi driven by interrupt expect a
logic with:
1. interrupt received. napi prepared -> interrupt disabled -> napi
scheduled
2. napi triggered. ring cleared -> interrupt enabled -> wait for new
interrupt
To prevent this case, disable the interrupt BEFORE the napi is
scheduled.

Before Google adopted FQ for its production servers,
we had to ensure AF4 packets would get a higher share
than BE1 ones.
As discussed this week in Netconf 2023 in Paris, it is time
to upstream this for public use.
After this patch FQ can replace pfifo_fast, with the following
differences :
- FQ uses WRR instead of strict prio, to avoid starvation of
low priority packets.
- We make sure each band/prio tracks its own usage against sch->limit.
This was done to make sure flood of low priority packets would not
prevent AF4 packets to be queued. Contributed by Willem.
- priomap can be changed, if needed (default value are the ones
coming from pfifo_fast).
In this patch, we set default band weights so that :
- high prio (band=0) packets get 90% of the bandwidth
if they compete with low prio (band=2) packets.
- high prio packets get 75% of the bandwidth
if they compete with medium prio (band=1) packets.
Following patch in this series adds the possibility to tune
the per-band weights.
As we added many fields in 'struct fq_sched_data', we had
to make sure to have the first cache line read-mostly, and
avoid wasting precious cache lines.
More optimizations are possible but will be sent separately.

Handle the case when GSO SKB linear length is too large.
MANA NIC requires GSO packets to put only the header part to SGE0,
otherwise the TX queue may stop at the HW level.
So, use 2 SGEs for the skb linear part which contains more than the
packet header.

For an unknown TX CQE error type (probably from a newer hardware),
still free the SKB, update the queue tail, etc., otherwise the
accounting will be wrong.
Also, TX errors can be triggered by injecting corrupted packets, so
replace the WARN_ONCE to ratelimited error logging.

`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 since card is already zero-initialized:
| card = kzalloc(sizeof(*card), GFP_KERNEL);
A suitable replacement is `strscpy` [2] due to the fact that it
guarantees NUL-termination on the destination buffer without
unnecessarily NUL-padding.

We add TX power table format for Wi-Fi 7 chips. Since Wi-Fi 7 tables are
larger, in order to reuse some chunks, we extend code to process nested

In ath12k the debug messages were broken, no matter setting what value to the
debug_mask module parameter would not get the debug messages printed. The issue
is that __ath12k_dbg() uses dev_dbg() to print the debug messages which requires either enabling
CONFIG_DYNAMIC_DEBUG or DEBUG symbol in the driver.
ath12k is supposed to use debug_mask module to control whether debug messages
are printed or not. Using both CONFIG_DYNAMIC_DEBUG and debug_mask parameter
does not make any sense so switch to using dev_printk(), just like ath11k does.
Now it's enough just to debug_mask module parameter to get the debug messages.

Tx power is fetched from firmware's pdev stats. However, during active
CAC, firmware does not fill the current Tx power and sends the max
initialised value filled during firmware init. If host sends this power
to user space, this is wrong since in certain situations, the Tx power
could be greater than the max allowed by the regulatory. Hence, host
should not be fetching the Tx power during an active CAC.
Fix this issue by returning -EAGAIN error so that user space knows that there's
no valid value available.

Currently channel definition's primary channel's DFS CAC time
as well as primary channel's state i.e usable are used to set
the CAC_RUNNING flag for the ath11k radio structure. However,
this is wrong since certain channel definition are possbile
where primary channel may not be a DFS channel but, secondary
channel is a DFS channel. For example - channel 36 with 160 MHz
bandwidth.
In such cases, the flag will not be set which is wrong.
Fix this issue by using cfg80211_chandef_dfs_usable() function
from cfg80211 which return trues if at least one channel is in
usable state.
While at it, modify the CAC running debug log message to print
the CAC time as well in milli-seconds.

Pull rtla fixes from Daniel Bristot de Oliveira:
"rtla (Real-Time Linux Analysis) tool fixes.
Timerlat auto-analysis:
- Timerlat is reporting thread interference time without thread noise
events occurrence. It was caused because the thread interference
variable was not reset after the analysis of a timerlat activation
that did not hit the threshold.
- The IRQ handler delay is estimated from the delta of the IRQ
latency reported by timerlat, and the timestamp from IRQ handler
start event. If the delta is near-zero, the drift from the external
clock and the trace event and/or the overhead can cause the value
to be negative. If the value is negative, print a zero-delay.
- IRQ handlers happening after the timerlat thread event but before
the stop tracing were being reported as IRQ that happened before
the *current* IRQ occurrence. Ignore Previous IRQ noise in this
condition because they are valid only for the *next* timerlat
activation.
Timerlat user-space:
- Timerlat is stopping all user-space thread if a CPU becomes
offline. Do not stop the entire tool if a CPU is/become offline,
but only the thread of the unavailable CPU. Stop the tool only, if
all threads leave because the CPUs become/are offline.

Currently, when hb_interval is changed by users, it won't take effect
until the next expiry of hb timer. As the default value is 30s, users
have to wait up to 30s to wait its hb_interval update to work.
This becomes pretty bad in containers where a much smaller value is
usually set on hb_interval. This patch improves it by resetting the
hb timer immediately once the value of hb_interval is updated by users.
Note that we don't address the already existing 'problem' when sending
a heartbeat 'on demand' if one hb has just been sent(from the timer)

During the 4-way handshake, the transport's state is set to ACTIVE in
sctp_process_init() when processing INIT_ACK chunk on client or
COOKIE_ECHO chunk on server.
In the collision scenario below:
192.168.1.2 > 192.168.1.1: sctp (1) [INIT] [init tag: 3922216408]
192.168.1.1 > 192.168.1.2: sctp (1) [INIT] [init tag: 144230885]
192.168.1.2 > 192.168.1.1: sctp (1) [INIT ACK] [init tag: 3922216408]
192.168.1.1 > 192.168.1.2: sctp (1) [COOKIE ECHO]
192.168.1.2 > 192.168.1.1: sctp (1) [COOKIE ACK]
192.168.1.1 > 192.168.1.2: sctp (1) [INIT ACK] [init tag: 3914796021]
when processing COOKIE_ECHO on 192.168.1.2, as it's in COOKIE_WAIT state,
sctp_sf_do_dupcook_b() is called by sctp_sf_do_5_2_4_dupcook() where it
creates a new association and sets its transport to ACTIVE then updates
to the old association in sctp_assoc_update().
However, in sctp_assoc_update(), it will skip the transport update if it
finds a transport with the same ipaddr already existing in the old asoc,
and this causes the old asoc's transport state not to move to ACTIVE
after the handshake.
This means if DATA retransmission happens at this moment, it won't be able
to enter PF state because of the check 'transport->state == SCTP_ACTIVE'
in sctp_do_8_2_transport_strike().
This patch fixes it by updating the transport in sctp_assoc_update() with
sctp_assoc_add_peer() where it updates the transport state if there is
already a transport with the same ipaddr exists in the old asoc.
