kmemdup() at line 2735 is not duplicating enough memory for
notif->tid_tear_down and notif->station_id. As it only duplicates
612 bytes: up to offsetofend(struct iwl_wowlan_info_notif,
received_beacons), this is the range of [0, 612) bytes.
2735 notif = kmemdup(notif_v1,
2736 offsetofend(struct iwl_wowlan_info_notif,
2737 received_beacons),
2738 GFP_ATOMIC);
which evidently does not cover bytes 612 and 613 for members
tid_tear_down and station_id in struct iwl_wowlan_info_notif.
See below:
$ pahole -C iwl_wowlan_info_notif drivers/net/wireless/intel/iwlwifi/mvm/d3.o
struct iwl_wowlan_info_notif {
struct iwl_wowlan_gtk_status_v3 gtk[2]; /* 0 488 */
/* --- cacheline 7 boundary (448 bytes) was 40 bytes ago --- */
struct iwl_wowlan_igtk_status igtk[2]; /* 488 80 */
/* --- cacheline 8 boundary (512 bytes) was 56 bytes ago --- */
__le64 replay_ctr; /* 568 8 */
/* --- cacheline 9 boundary (576 bytes) --- */
__le16 pattern_number; /* 576 2 */
__le16 reserved1; /* 578 2 */
__le16 qos_seq_ctr[8]; /* 580 16 */
__le32 wakeup_reasons; /* 596 4 */
__le32 num_of_gtk_rekeys; /* 600 4 */
__le32 transmitted_ndps; /* 604 4 */
__le32 received_beacons; /* 608 4 */
u8 tid_tear_down; /* 612 1 */
u8 station_id; /* 613 1 */
u8 reserved2[2]; /* 614 2 */
/* size: 616, cachelines: 10, members: 13 */
/* last cacheline: 40 bytes */
};
Therefore, when the following assignments take place, actually no memory
has been allocated for those objects:
2743 notif->tid_tear_down = notif_v1->tid_tear_down;
2744 notif->station_id = notif_v1->station_id;
Fix this by allocating space for the whole notif object and zero out the
remaining space in memory after member station_id.
This also fixes the following -Warray-bounds issues:

Currently, whenever an EMA beacon is formed, due to is_template
argument being false from the caller, the switch count is always
decremented once which is wrong.
Also if switch count is equal to profile periodicity, this makes
the switch count to reach till zero which triggers a WARN_ON_ONCE.

There were two bugs when creating the non-inheritence
element:
1) 'at_extension' needs to be declared outside the loop,
otherwise the value resets every iteration and we
can never really switch properly
2) 'added' never got set to true, so we always cut off
the extension element again at the end of the function
This shows another issue that we might add a list but no
extension list, but we need to make the extension list a
zero-length one in that case.
Fix all these issues. While at it, add a comment explaining
the trim.

Move capturing the snapshot context into the image request state
machine, after exclusive lock is ensured to be held for the duration of
dealing with the image request. This is needed to ensure correctness
of fast-diff states (OBJECT_EXISTS vs OBJECT_EXISTS_CLEAN) and object
deltas computed based off of them. Otherwise the object map that is
forked for the snapshot isn't guaranteed to accurately reflect the
contents of the snapshot when the snapshot is taken under I/O. This
breaks differential backup and snapshot-based mirroring use cases with
fast-diff enabled: since some object deltas may be incomplete, the
destination image may get corrupted.

L2CAP assumes that the locks conn->chan_lock and chan->lock are
acquired in the order conn->chan_lock, chan->lock to avoid
potential deadlock.
For example, l2sock_shutdown acquires these locks in the order:
mutex_lock(&conn->chan_lock)
l2cap_chan_lock(chan)
However, l2cap_disconnect_req acquires chan->lock in
l2cap_get_chan_by_scid first and then acquires conn->chan_lock
before calling l2cap_chan_del. This means that these locks are
acquired in unexpected order, which leads to potential deadlock:
l2cap_chan_lock(c)
mutex_lock(&conn->chan_lock)
This patch releases chan->lock before acquiring the conn_chan_lock
to avoid the potential deadlock.

The existing documentation refers to memory.high as the "main mechanism
to control memory usage." This seems incorrect to me - memory.high can
result in reclaim pressure which simply leads to stalls unless some
external component observes and actions on it (e.g. systemd-oomd can be
used for this purpose). While this is feasible, users are unaware of
this interaction and are led to believe that memory.high alone is an
effective mechanism for limiting memory.
The documentation should recommend the use of memory.max as the
effective way to enforce memory limits - it triggers reclaim and results
in OOM kills by itself.

Qualcomm ARM64 DeviceTree fixes for 6.4
Register scheme for SM8550 LLCC is corrected to avoid using the wrong
register offsets. SDRAM frequency for misidentified SC7180-lite boards
is handled. The datatype for Soundwire interval on SM8550 is corrected.
The resource controller on SC8280XP is added to the CPU cluster
power-domain to get notified to send cached sleep and wake votes before
going entering the lower power states.
SA8155P power-domains that differ from what's inherited from the SM8150
DeviceTree are adjusted to make the platform boot again.
Remoteproc firmware paths are corrected for Sony Xperia 10 IV.
Cache properties are adjusted across a range of platforms, to meet
changes in the binding.
Panel compatibles are corrected for Xiaomi Mi Pad 5 Pro, to match
binding. Invalid dai-cells are dropped from SC7280 devices, to match
binding.
The incorrect removal of "input-enable" from the LPASS pinctrl node of
SC8280XP was reverted, to get dmic pins in the correct state again.
The incorrect input-enable property is dropped from a msm8974, mdm9615
and apq8026 to resolve a range of DT validation warnings, incorrectly
picked up through the ARM64 tree.

mptcp: Fixes for address advertisement
Patches 1 and 2 allow address advertisements to be removed without
affecting current connected subflows, and updates associated self tests.
Patches 3 and 4 correctly track (and allow removal of) addresses that
were implicitly announced as part of subflow creation. Also updates
associated self tests.
Patch 5 makes subflow and address announcement counters work consistently
between the userspace and in-kernel path managers.

Increase pm subflows counter on both server side and client side when
userspace pm creates a new subflow, and decrease the counter when it
closes a subflow.
Increase add_addr_signaled counter in mptcp_nl_cmd_announce() when the
address is announced by userspace PM.
This modification is similar to how the in-kernel PM is updating the
counter: when additional subflows are created/removed.

Add the address into userspace_pm_local_addr_list when the subflow is
created. Make sure it can be found in mptcp_nl_cmd_remove(). And delete
it in the new helper mptcp_userspace_pm_delete_local_addr().
By doing this, the "REMOVE" command also works with subflows that have
been created via the "SUB_CREATE" command instead of restricting to
the addresses that have been announced via the "ANNOUNCE" command.

The specifications from [1] about the "REMOVE" command say:
Announce that an address has been lost to the peer
It was then only supposed to send a RM_ADDR and not trying to delete
associated subflows.
A new helper mptcp_pm_remove_addrs() is then introduced to do just
that, compared to mptcp_pm_remove_addrs_and_subflows() also removing
subflows.
To delete a subflow, the userspace daemon can use the "SUB_DESTROY"
command, see mptcp_nl_cmd_sf_destroy().

There seems to be a bug within the mv64xxx I2C controller, wherein the
status register may not necessarily contain valid value immediately
after the IFLG flag is set in the control register.
My theory is that the controller:
- first sets the IFLG in control register
- then updates the status register
- then raises an interrupt
This may sometime cause weird bugs when in atomic mode, since in this
mode we do not wait for an interrupt, but instead we poll the control
register for IFLG and read status register immediately after.
I encountered -ENXIO from mv64xxx_i2c_fsm() due to this issue when using
this driver in atomic mode.
Note that I've only seen this issue on Armada 385, I don't know whether
other SOCs with this controller are also affected. Also note that this
fix has been in U-Boot for over 4 years [1] without anybody complaining,
so it should not cause regressions.

====================
this is a pull request of 3 patches for net/master.
All 3 patches target the j1939 stack.
The 1st patch is by Oleksij Rempel and fixes the error queue handling
for (E)TP sessions that run into timeouts.
The last 2 patches are by Fedor Pchelkin and fix a potential
use-after-free in j1939_netdev_start() if j1939_can_rx_register()
fails.

With IC_INTR_RX_FULL slave interrupt handler reads data in a loop until
RX FIFO is empty. When testing with the slave-eeprom, each transaction
has 2 bytes for address/index and 1 byte for value, the address byte
can be written as data byte due to dropping STOP condition.
In the test below, the master continuously writes to the slave, first 2
bytes are index, 3rd byte is value and follow by a STOP condition.
i2c_write: i2c-3 #0 a=04b f=0000 l=3 [00-D1-D1]
i2c_write: i2c-3 #0 a=04b f=0000 l=3 [00-D2-D2]
i2c_write: i2c-3 #0 a=04b f=0000 l=3 [00-D3-D3]
Upon receiving STOP condition slave eeprom would reset `idx_write_cnt` so
next 2 bytes can be treated as buffer index for upcoming transaction.
Supposedly the slave eeprom buffer would be written as
EEPROM[0x00D1] = 0xD1
EEPROM[0x00D2] = 0xD2
EEPROM[0x00D3] = 0xD3
When CPU load is high the slave irq handler may not read fast enough,
the interrupt status can be seen as 0x204 with both DW_IC_INTR_STOP_DET
(0x200) and DW_IC_INTR_RX_FULL (0x4) bits. The slave device may see
the transactions below.
0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x1594 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x1594 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x1594 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x1794 : INTR_STAT=0x204
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x1790 : INTR_STAT=0x200
0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x1594 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x1594 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x1594 : INTR_STAT=0x4
After `D1` is received, read loop continues to read `00` which is the
first bype of next index. Since STOP condition is ignored by the loop,
eeprom buffer index increased to `D2` and `00` is written as value.
So the slave eeprom buffer becomes
EEPROM[0x00D1] = 0xD1
EEPROM[0x00D2] = 0x00
EEPROM[0x00D3] = 0xD3
The fix is to use `FIRST_DATA_BYTE` (bit 11) in `IC_DATA_CMD` to split
the transactions. The first index byte in this case would have bit 11
set. Check this indication to inject I2C_SLAVE_WRITE_REQUESTED event
which will reset `idx_write_cnt` in slave eeprom.

Rather than casting pci1xxxx_i2c_shutdown to an incompatible function type,
update the type to match that expected by __devm_add_action.
Reported by clang-16 with W-1:
.../i2c-mchp-pci1xxxx.c:1159:29: error: cast from 'void (*)(struct pci1xxxx_i2c *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict]
ret = devm_add_action(dev, (void (*)(void *))pci1xxxx_i2c_shutdown, i2c);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
./include/linux/device.h:251:29: note: expanded from macro 'devm_add_action'
__devm_add_action(release, action, data, #action)
^~~~~~
No functional change intended.
Compile tested only.
