9e010737dd ARM: dts: rockchip: add rk3036 usb2phy nodes and enable them on kylin
The rk3036 does contain a usb2phy, just until now it was just used
implicitly without additional configuration. As we now have the bits
in place for it getting actually controlled, add the necessary phy-node
to the GRF simple-mfd.

Enable the phy-ports in the same patch to not create bisectability
issues, as hooking up the phys to the usb controllers would create
probe deferrals until a board enables them. Doing everything in one
patch, solves that issue.

Only rk3036-kylin actually enabled the usb controllers, so is the only
board affected.

34d2730fbb arm64: dts: rockchip: move rk3528 i2c+uart aliases to board files
Even though they will be the same for all boards, i2c and uart aliases
are supposed to live in the individual board files, to not create
aliases for disabled nodes.

So move the newly added aliases for rk3528 over to the Radxa E20C board,
which is the only rk3528 board right now.

67fa756408 Merge branch 'octeontx2-improve-mailbox-tracing'
Subbaraya Sundeep says:

====================
octeontx2: Improve mailbox tracing

Octeontx2 VF,PF and AF devices communicate using hardware
shared mailbox region where VFs can only to talk to its PFs
and PFs can only talk to AF. AF does the entire resource management
for all PFs and VFs. The shared mbox region is used for synchronous
requests (requests from PF to AF or VF to PF) and async notifications
(notifications from AF to PFs or PF to VFs). Sending a request to AF
from VF involves various stages like
1. VF allocates message in shared region
2. Triggers interrupt to PF
3. PF upon receiving interrupt from VF will copy the message
   from VF<->PF region to PF<->AF region
4. Triggers interrupt to AF
5. AF processes it and writes response in PF<->AF region
6. Triggers interrupt to PF
7. PF copies responses from PF<->AF region to VF<->PF region
8. Triggers interrupt to Vf
9. VF reads response in VF<->PF region

Due to various stages involved, Tracepoints are used in mailbox code for
debugging. Existing tracepoints need some improvements so that maximum
information can be inferred from trace logs during an issue.
This patchset tries to enhance existing tracepoints and also adds
a couple of tracepoints.

fa00077d8f octeontx2: Add new tracepoint otx2_msg_status
Apart from netdev interface Octeontx2 PF does the following:
1. Sends its own requests to AF and receives responses from AF.
2. Receives async messages from AF.
3. Forwards VF requests to AF, sends respective responses from AF to VFs.
4. Sends async messages to VFs.
This patch adds new tracepoint otx2_msg_status to display the status
of PF wrt mailbox handling.

This patch adds pcifunc which represents PF and VF device to the
tracepoints otx2_msg_alloc, otx2_msg_send, otx2_msg_process so that
it is easier to correlate which device allocated the message, which
device forwarded it and which device processed that message.

UBSAN: array-index-out-of-bounds in net/mac80211/scan.c:1208:5
index 0 is out of range for type 'struct ieee80211_channel *[] __counted_by(n_channels)' (aka 'struct ieee80211_channel *[]')

This was missed in the initial conversions because I failed to locate
the allocation likely due to the "sizeof(void *)" not matching the
"channels" array type.

c16608005c net: Look for bonding slaves in the bond's network namespace
Update the for_each_netdev_in_bond_rcu macro to iterate through network
devices in the bond's network namespace instead of always using
init_net. This change is safe because:

1. **Bond-Slave Namespace Relationship**: A bond device and its slaves
   must reside in the same network namespace. The bond device's
   namespace is established at creation time and cannot change.

2. **Slave Movement Implications**: Any attempt to move a slave device
   to a different namespace automatically removes it from the bond, as
   per kernel networking stack rules.
   This maintains the invariant that slaves must exist in the same
   namespace as their bond.

This change is part of an effort to enable Link Aggregation (LAG) to
work properly inside custom network namespaces. Previously, the macro
would only find slave devices in the initial network namespace,
preventing proper bonding functionality in custom namespaces.

40d48527a5 ovpn: fix check for skb_to_sgvec_nomark() return value
Depending on the data offset, skb_to_sgvec_nomark() may use
less scatterlist elements than what was forecasted by the
previous call to skb_cow_data().

It specifically happens when 'skbheadlen(skb) < offset', because
in this case we entirely skip the skb's head, which would have
required its own scatterlist element.

For this reason, it doesn't make sense to check that
skb_to_sgvec_nomark() returns the same value as skb_cow_data(),
but we can rather check for errors only, as it happens in
other parts of the kernel.

47e8e9d29e ovpn: fix ndo_start_xmit return value on error
ndo_start_xmit is basically expected to always return NETDEV_TX_OK.
However, in case of error, it was currently returning NET_XMIT_DROP,
which is not a valid netdev_tx_t return value, leading to
misinterpretation.

Change ndo_start_xmit to always return NETDEV_TX_OK to signal back
to the caller that the packet was handled (even if dropped).

Effects of this bug can be seen when sending IPv6 packets having
no peer to forward them to:

  $ ip netns exec ovpn-server oping -c20 fd00🔡220:201::1
  PING fd00🔡220:201::1 (fd00🔡220:201::1) 56 bytes of data.00🔡220:201 :1

4ca6438da4 ovpn: don't drop skb's dst when xmitting packet
When routing a packet to a LAN behind a peer, ovpn needs to
inspect the route entry that brought the packet there in the
first place.

If this packet is truly routable, the route entry provides the
GW to be used when looking up the VPN peer to send the packet to.

However, the route entry is currently dropped before entering
the ovpn xmit function, because the IFF_XMIT_DST_RELEASE priv_flag
is enabled by default.

Clear the IFF_XMIT_DST_RELEASE flag during interface setup to allow
the route entry (skb's dst) to survive and thus be inspected
by the ovpn routing logic.

4e51141f1d ovpn: set skb->ignore_df = 1 before sending IPv6 packets out
IPv6 user packets (sent over the tunnel) may be larger than
the outgoing interface MTU after encapsulation.
When this happens ovpn should allow the kernel to fragment
them because they are "locally generated".

To achieve the above, we must set skb->ignore_df = 1
so that ip6_fragment() can be made aware of this decision.

Failing to do so will result in ip6_fragment() dropping
the packet thinking it was "routed".

No change is required in the IPv4 path, because when
calling udp_tunnel_xmit_skb() we already pass the
'df' argument set to 0, therefore the resulting datagram
is allowed to be fragmented if need be.

dcb479fde0 octeontx2-pf: Do not reallocate all ntuple filters
If ntuple filters count is modified followed by
unicast filters count using devlink then the ntuple count
set by user is ignored and all the ntuple filters are
being reallocated. Fix this by storing the ntuple count
set by user. Without this patch, say if user tries
to modify ntuple count as 8 followed by ucast filter count as 4
using devlink commands then ntuple count is being reverted to
default value 16 i.e, not retaining user set value 8.

Enabling of the temperature sensor was moved from mv88q2xxx_hwmon_probe to
mv88q222x_config_init with the consequence that the sensor is only
usable when the PHY is configured. Enable the sensor in
mv88q2xxx_hwmon_probe as well to fix this.

We shouldn't use xe_managed_bo_create_from_data() to allocate

Merge patch series "Use folios for symlinks in the page cache"
Matthew Wilcox (Oracle) <willy@infradead.org> says:

FUSE already uses folios for its symlinks.  Mirror that conversion in
the generic code and the NFS code.  That lets us get rid of a few
folio->page->folio conversions in this path, and some of the few
remaining users of read_cache_page() / read_mapping_page().

12cbd15734 i3c: master: svc: skip address resend on repeat START
According to the I3C specification, address arbitration only happens during
the START. Repeated START do not initiate arbitration, and In-Band
Interrupts (IBIs) cannot occur at this stage.

Resending the address upon a NACK in a repeat START is therefore redundant
and unnecessary. Avoid redundant retries, improving efficiency and ensuring
protocol compliance.

8d29fa6d92 i3c: master: svc: Receive IBI requests in interrupt context
Moving the job from workqueue to ISR for two reasons.

1. Improve bus utilization.
If the requests are postponed to be received in the workqueue thread,
the SDA line remains low for a long time while the system loading is
high. During this period, the bus is not available for other targets
to raise requests.

2. Ensure prompt response to requests.
For timing-critical requests, the target may encouter a failure or the
event is missed if the request is not received in time.

IBI request is short, ISR can receive the data quickly and then queue a
work to handle it in the bottom half.
