The channel context has to be bound with the per-link BSS, thus,
we extend mt7925_mcu_[abort, set]_roc to work with the per-link BSS
configuration.

We are introducing a new structure, mt792x_link_sta, to manage per-link
configurations in preparation for future station (STA) support of
Multi-Link Operation (MLO).
This patch only includes structural changes and does not involve any
logic changes.
We have moved relevant parameters, such as the wcid from the mt76_wcid
structure, from the mt7921x_sta structure to the mt792x_link_sta structure.
For current drivers that do not support MLO, there is only one link STA,
and link information is accessed via the deflink member.
However, we have not yet created the per-link BSS configuration indexed
by link ID for Multi-Link Device (MLD) support in mt7921x_sta.
This step needs to be completed before adding MLD support for STA mode.

We are introducing a new structure, mt792x_bss_conf, to manage per-link
configurations in preparation for future STA support of Multi-Link
Operation (MLO).
The patch does not include any logic changes, only structural changes.
We have moved relevant parameters from the mt7921x_vif structure such
as to mt76 of mt76_vif structure, rssi and Tx queue parameters to
mt7921x_bss_conf structure. We can access those members to configure the
BSS for this interface, whether it is our own BSS or the one we are
associated with.
However, we have not yet created the per-link BSS configuration indexed by
link ID for Multi-Link Device (MLD) support. This step needs to be
extended before adding MLD support for AP mode.

X would not start in my old 32-bit partition (and the "n"-handling looks
just as wrong on 64-bit, but for whatever reason did not show up there):
"n" must be accumulated over all pages before it's added to "offset" and
compared with "copy", immediately after the skb_frag_foreach_page() loop.

Pass union tls_crypto_context pointer, rather than struct
tls_crypto_info pointer, to memzero_explicit().
The address of the pointer is the same before and after.
But the new construct means that the size of the dereferenced pointer type
matches the size being zeroed. Which aids static analysis.
As reported by Smatch:
.../tls_main.c:842 do_tls_setsockopt_conf() error: memzero_explicit() 'crypto_info' too small (4 vs 56)
No functional change intended.

Like other SPI controller flags, bits_per_word_mask may be used by a
peripheral driver, so it needs to reflect the capabilities of the
underlying controller.

Adding spi_optimize_message() broke the spi-mux driver because it
calls spi_async() from it's transfer_one_message() callback. This
resulted in passing an incorrectly optimized message to the controller.
For example, if the underlying controller has an optimize_message()
callback, this would have not been called and can cause a crash when
the underlying controller driver tries to transfer the message.
Also, since the spi-mux driver swaps out the controller pointer by
replacing msg->spi, __spi_unoptimize_message() was being called with a
different controller than the one used in __spi_optimize_message(). This
could cause a crash when attempting to free the message resources when
__spi_unoptimize_message() is called in spi_finalize_current_message()
since it is being called with a controller that did not allocate the
resources.
This is fixed by adding a defer_optimize_message flag for controllers.
This flag causes all of the spi_[maybe_][un]optimize_message() calls to
be a no-op (other than attaching a pointer to the spi device to the
message).
This allows the spi-mux driver to pass an unmodified message to
spi_async() in spi_mux_transfer_one_message() after the spi device has
been swapped out. This causes __spi_optimize_message() and
__spi_unoptimize_message() to be called only once per message and with
the correct/same controller in each case.

Calling spi_maybe_unoptimize_message() in spi_async() is wrong because
the message is likely to be in the queue and not transferred yet. This
can corrupt the message while it is being used by the controller driver.
spi_maybe_unoptimize_message() is already called in the correct place
in spi_finalize_current_message() to balance the call to
spi_maybe_optimize_message() in spi_async().

Since commit c49cfa917025 ("USB: serial: use generic method if no
alternative is provided in usb serial layer"), USB serial core calls the
generic resume implementation when the driver has not provided one.
This can trigger a crash on resume with mos7840 since support for
multiple read URBs was added back in 2011. Specifically, both port read
URBs are now submitted on resume for open ports, but the context pointer
of the second URB is left set to the core rather than mos7840 port
structure.
Fix this by implementing dedicated suspend and resume functions for
mos7840.
Tested with Delock 87414 USB 2.0 to 4x serial adapter.

====================
pull-request: bpf-next 2024-07-08
The following pull-request contains BPF updates for your *net-next* tree.
We've added 102 non-merge commits during the last 28 day(s) which contain
a total of 127 files changed, 4606 insertions(+), 980 deletions(-).
The main changes are:
1) Support resilient split BTF which cuts down on duplication and makes BTF
as compact as possible wrt BTF from modules, from Alan Maguire & Eduard Zingerman.
2) Add support for dumping kfunc prototypes from BTF which enables both detecting
as well as dumping compilable prototypes for kfuncs, from Daniel Xu.
3) Batch of s390x BPF JIT improvements to add support for BPF arena and to implement
support for BPF exceptions, from Ilya Leoshkevich.
4) Batch of riscv64 BPF JIT improvements in particular to add 12-argument support
for BPF trampolines and to utilize bpf_prog_pack for the latter, from Pu Lehui.
5) Extend BPF test infrastructure to add a CHECKSUM_COMPLETE validation option
for skbs and add coverage along with it, from Vadim Fedorenko.
6) Inline bpf_get_current_task/_btf() helpers in the arm64 BPF JIT which gives
a small 1% performance improvement in micro-benchmarks, from Puranjay Mohan.
7) Extend the BPF verifier to track the delta between linked registers in order
to better deal with recent LLVM code optimizations, from Alexei Starovoitov.
8) Fix bpf_wq_set_callback_impl() kfunc signature where the third argument should
have been a pointer to the map value, from Benjamin Tissoires.
9) Extend BPF selftests to add regular expression support for test output matching
and adjust some of the selftest when compiled under gcc, from Cupertino Miranda.
10) Simplify task_file_seq_get_next() and remove an unnecessary loop which always
iterates exactly once anyway, from Dan Carpenter.
11) Add the capability to offload the netfilter flowtable in XDP layer through
kfuncs, from Florian Westphal & Lorenzo Bianconi.
12) Various cleanups in networking helpers in BPF selftests to shave off a few
lines of open-coded functions on client/server handling, from Geliang Tang.
13) Properly propagate prog->aux->tail_call_reachable out of BPF verifier, so
that x86 JIT does not need to implement detection, from Leon Hwang.
14) Fix BPF verifier to add a missing check_func_arg_reg_off() to prevent an
out-of-bounds memory access for dynpointers, from Matt Bobrowski.
15) Fix bpf_session_cookie() kfunc to return __u64 instead of long pointer as
it might lead to problems on 32-bit archs, from Jiri Olsa.
16) Enhance traffic validation and dynamic batch size support in xsk selftests,
from Tushar Vyavahare.

crst_table_free() used to work with NULL pointers before the conversion
to ptdescs. Since crst_table_free() can be called with a NULL pointer
(error handling in crst_table_upgrade() add an explicit check.
Also add the same check to base_crst_free() for consistency reasons.
In real life this should not happen, since order two GFP_KERNEL
allocations will not fail, unless FAIL_PAGE_ALLOC is enabled and used.

When SMP is enabled and spinlocks are actually functional then there is

This issue has not been identified earlier because tests were done on
a device with SMP disabled and so spinlocks were actually NOPs.
Now use spin_(un)lock_bh for TX queue related locking to avoid execution
of softirq work synchronously that would lead to a deadlock.

rvu_check_rsrc_availability()
In rvu_check_rsrc_availability() in case of invalid SSOW req, an incorrect
data is printed to error log. 'req->sso' value is printed instead of
'req->ssow'. Looks like "copy-paste" mistake.
Fix this mistake by replacing 'req->sso' with 'req->ssow'.

In the cases where the power domain connected to logics is allowed to
transition from a level(L)-->power collapse(0)-->retention(1) or
vice versa retention(1)-->power collapse(0)-->level(L) will cause the
logic to lose the configurations. The ARC does not support retention
to collapse transition on MxC rails.
The targets from SM8450 onwards the PLL logics of clock controllers are
connected to MxC rails and the recommended configurations are carried
out during the clock controller probes. The MxC transition as mentioned
above should be skipped to ensure the PLL settings are intact across
clock controller power on & off.
On older targets that do not split MX into MxA and MxC does not collapse
the logic and it is parked always at RETENTION, thus this issue is never
observed on those targets.

mwifiex_get_priv_by_id() returns the priv pointer corresponding to
the bss_num and bss_type, but without checking if the priv is actually
currently in use.
Unused priv pointers do not have a wiphy attached to them which can
lead to NULL pointer dereferences further down the callstack. Fix
this by returning only used priv pointers which have priv->bss_mode
set to something else than NL80211_IFTYPE_UNSPECIFIED.
Said NULL pointer dereference happened when an Accesspoint was started
with wpa_supplicant -i mlan0 with this config:
network={
ssid="somessid"
mode=2
frequency=2412
key_mgmt=WPA-PSK WPA-PSK-SHA256
proto=RSN
group=CCMP
pairwise=CCMP
psk="12345678"
}
When waiting for the AP to be established, interrupting wpa_supplicant
with <ctrl-c> and starting it again this happens:
