The sk_msg sg.copy bitmap is part of the scatterlist entry ownership
state. A set bit tells sk_msg_compute_data_pointers() not to expose the
entry through writable BPF ctx->data. This protects entries backed by
pages that are not private to the sk_msg, such as splice-backed file
page-cache pages.
Several sk_msg transform paths move, copy, split, or compact
msg->sg.data[] entries without moving the matching sg.copy bit. This can
make an externally backed entry arrive at a new slot with a clear copy
bit. A later SK_MSG verdict can then expose sg_virt(sge) as writable
ctx->data and BPF stores can modify the original page cache.
Keep sg.copy synchronized with sg.data[] whenever entries are
transferred, shifted, split, or copied into a new sk_msg. Clear the bit
when an entry is replaced by a newly allocated private page or freed.
This covers the BPF pull/push/pop helpers, sk_msg_shift_left/right(),
sk_msg_xfer(), and tls_split_open_record(), including the partial tail
entry created during TLS open-record splitting.

====================
MAC-PHY interrupt changed to level triggered interrupt
According to OPEN Alliance 10BASE-T1x MAC-PHY Serial Interface
specification, MAC-PHY interrupt is "active low, level triggered".
The specification mentions about the conditions in which the IRQ
is asserted and deasserted.
Bug is inadvertently introduced by treating the IRQ in the OA TC6
framework driver and in dt-binding YAML file as edge triggered.
With the changes to use level triggered interrupt, use of threaded
irq is more efficient than the current method that has interrupt hander
working with work queue.
This change of interrupt handler mechanism exposed couple of race
conditions due to the fact that interrupts were not masked on protocol
error. And pointers were not initialized with null after skbs are freed.
Changes are done in two files
- OA TC6 framework Ethernet driver
- YAML file for the vendor that already uses OA TC6 framework.
Maintainer for this driver is already informed and aware of these
changes. Testing for these changes was done in onsemi's setup and
found to be working.

Specification calls for when interrupt level will be asserted and what
condition it is de-asserted. By using edge triggered interrupt, there is a
potential chance to miss it, particularly if it is asserted when interrupt

Level triggered interrupt can't be missed as it gets de-asserted only on
interrupt handler taking actions on interrupting conditions.

OA TC6 MAC-PHY appends FCS to the incoming frame. It must be
removed from the frame before being passed to the stack.
With FCS in the frame, many applications, like ping or any
application that uses IP layer may work as they may
carry the packet size information in the protocol.
Application like ptp4l, particularly if it uses layer 2
for its communication, it will fail with "bad message" due to
the extra 4 bytes added by the presence of FCS.

According OPEN Alliance 10BASET1x MAC-PHY Serial Interface
specification, interrupt is active low, level triggered.
Code used edge triggered interrupt which has the risk of losing an
interrupt on instances like when interrupt is disabled. Level
triggered interrupt won't be deasserted unless handler runs and
clear the interrupting conditions.
Interrupt handler mechanism is changed to threaded irq from
interrupt handler and kernel thread waiting on work queue.
Threaded irq mechanism is best suited for level triggered interrupt
as it disables the interrupt until handler is run in thread level,
while giving us an ability to have interrupt context handler to
signal the threaded irq handler.
Introduced a logic to disable the device interrupt on error. Error
could be due in data chunk's header and footer or SPI interface itself.
This will avoid having repeated interrupts, in case the driver couldn't
recover from the error condition with the available recovery mechanism.

it always sets the CPPI5 descriptor destination tag to emac->port_id,
which directs the PRU firmware to transmit on only one slave port in HSR
mode, breaking redundancy.
Apply the same fix: in HSR offload mode when NETIF_F_HW_HSR_DUP is set,
use PRUETH_UNDIRECTED_PKT_DST_TAG (port 0) so the PRU duplicates frames
to both ports. Also set PRUETH_UNDIRECTED_PKT_TAG_INS when
NETIF_F_HW_HSR_TAG_INS is set so the PRU re-inserts the HSR sequence tag
that was stripped by the PRU on RX before the XDP program saw the frame.
This ensures XSK XDP_TX frames in HSR mode are treated identically to

emac_xmit_xdp_frame() always sets the CPPI5 descriptor destination

this bypasses the firmware's HSR duplication logic: the frame goes
out on one ring leg and never appears on the other, breaking HSR
redundancy for XDP_TX paths.
icssg_ndo_start_xmit() already handles this correctly: when HSR
offload mode is active and NETIF_F_HW_HSR_DUP is set it substitutes
PRUETH_UNDIRECTED_PKT_DST_TAG (port 0) so the PRU duplicates the

emac_rx_packet_zc() calls prueth_rx_alloc_zc() with count (frames
received in the current NAPI poll) as the allocation budget. Two
problems arise from this:
1. When the CPPI5 descriptor pool is exhausted (avail_desc == 0,
FDQ already holds the maximum number of descriptors), count > 0
still triggers allocation attempts that all fail, spamming the
kernel log with "rx push: failed to allocate descriptor" at
high packet rates.
2. The XSK wakeup condition "ret < count" is wrong when avail_desc
is zero: ret == 0 and count can be up to 64, so the condition is
always true. This causes ~200 spurious ndo_xsk_wakeup() calls
per second even when the FDQ is already full, wasting CPU cycles
in repeated NAPI invocations that process zero frames.
Fix both by introducing alloc_budget = min(budget, avail_desc):
- When avail_desc == 0 no allocation is attempted, avoiding pool
exhaustion errors. The wakeup condition "ret < alloc_budget"
evaluates to 0 < 0 == false, correctly clearing the wakeup flag
so the hardware IRQ re-arms NAPI without spurious kicks.
- In steady state avail_desc == count <= budget, so alloc_budget
== count and behaviour is unchanged.
- After a dry-ring stall (count == 0, avail_desc > 0), alloc_budget
> 0 causes new descriptors to be posted to the FDQ so the hardware
can resume receiving immediately.

When MTU is large, ip6_default_advmss() can return IPV6_MAXPLEN (65535).

However, 0xFFFF is also used as a magic value GSO_BY_FRAGS in the kernel.
If a TCP packet with gso_size=0xFFFF is passed to skb_segment(), it will
be mistakenly treated as GSO_BY_FRAGS, leading to a NULL pointer
dereference because local TCP packets do not use frag_list.
Fix this by returning min(IPV6_MAXPLEN, GSO_BY_FRAGS - 1) (65534) from
ip6_default_advmss() when MTU is large.
Also update the stale comment in ip6_default_advmss() which suggested

The root cause is that tipc_disable_l2_media() calls synchronize_net()
while b->media_ptr is still valid. This allows concurrent RCU readers
to obtain the device pointer after synchronize_net() has finished.
The pointer is cleared later in bearer_disable(), but without any
subsequent synchronization, allowing the device to be freed while
still in use by readers.
Fix this by clearing b->media_ptr in tipc_disable_l2_media() before
calling synchronize_net().
This is safe to do now because the call order in bearer_disable()

octeontx2: quiesce stale mailbox IRQ state before request_irq()
Both OTX2 mailbox registration paths currently install their IRQ
handlers before clearing stale local mailbox interrupt state, even
though the code comments already say that the clear is needed first to
avoid spurious interrupts.
This issue was found by our static analysis tool and manually audited on
Linux v6.18.21. Directed QEMU no-device validation further showed that
the real PF and VF mailbox handlers are already reachable in that
pre-clear window and can touch the same mailbox and workqueue carrier
before local quiesce has completed.
This series keeps the change minimal:
- clear stale mailbox interrupt state before request_irq()
- keep interrupt enabling after the handler is installed
That closes the early-IRQ window without introducing a new
enable-before-handler window.
Patch 1 fixes the PF mailbox registration path.
Patch 2 fixes the VF mailbox registration path.
Build-tested by compiling otx2_pf.o and otx2_vf.o.
No OTX2 hardware was available for end-to-end runtime testing.

Under heavy network traffic, we observed sporadic TX queue timeouts on the
Raspberry Pi 4. The timeouts can be reproduced by stress testing the TX
path with multiple concurrent iperf UDP streams:
iperf3 -c <ip> -u -b0 -P16 -t60
NETDEV WATCHDOG: CPU: 0: transmit queue 0 timed out 2044 ms
NETDEV WATCHDOG: CPU: 3: transmit queue 0 timed out 2004 ms
Investigation showed that the timeouts are caused by the priority-based
arbiter. Under heavy load the highest priority queue starves the lower
priority ones, causing timeouts. The TX strict priority arbiter is not
suitable for the default use case where all the traffic gets spread
across all the TX queues.
Therefore, to fix this, switch the TX DMA arbiter to Weighted Round-Robin,
which services all queues, so they do not stall. The weights were chosen
to follow the existing priority scheme: q0 gets the smallest weight, while
q1-4 get the bulk of the TX bandwidth.

The max_macs devlink param is checked against the FW max value only at
param register time (driver load) and inside the validate callback
(devlink param set). The stored DRIVERINIT value persists across FW
resets and devlink reloads without any further checks against the max.
If the FW link type changes from Ethernet to IB and a FW reset happens,
the MAX cap for log_max_current_uc_list will become zero, but the
previously stored max_macs value remains and is unconditionally
programmed into the HCA caps in handle_hca_cap(). FW will then return a
syndrome during SET_HCA_CAP:
mlx5_cmd_out_err:839:(pid 3831): SET_HCA_CAP(0x109) op_mod(0x0) failed,
status bad parameter(0x3), syndrome (0x537801), err(-22)
set_hca_cap:907:(pid 3831): handle_hca_cap failed
This results in a failure to register the RDMA device.
This patch skips programming log_max_current_uc_list when the MAX
capability is 0 (in case of IB).

When a qdisc is added by name, the kernel tries to autoload its module
via request_qdisc_module(), which calls:
request_module(NET_SCH_ALIAS_PREFIX "%s", name);
i.e. it asks modprobe to resolve the "net-sch-<kind>" alias (e.g.
"net-sch-dualpi2") rather than the module's file name. Since dualpi2
was shipped without this alias, the autoload fails:

By introducing dev->watchdog_dev_tracker to store the

2) Remove netdev_watchdog_up() call from netif_carrier_on():

(via linkwatch workqueue dev_activate()), allowing us to use
spin_lock_bh() for synchronization.
3) Synchronize watchdog up and watchdog timer:
Protect netdev_watchdog_up() with tx_global_lock and watchdog_lock.

net: mana: fix error-path issues in queue setup
Two error-path fixes in MANA queue setup, both surfaced during Sashiko
AI review of a recently upstreamed patch series.
Patch 1 initializes queue->id to INVALID_QUEUE_ID in
mana_gd_create_mana_wq_cq() so that a CQ creation failure before the
firmware id is assigned does not NULL gc->cq_table[0] and silently
break whichever real CQ owns that slot. This mirrors the existing
pattern in mana_gd_create_eq().
Patch 2 guards mana_destroy_txq()'s call to mana_destroy_wq_obj() with
an INVALID_MANA_HANDLE check, mirroring mana_destroy_rxq(). Without
it, TX setup failures lead to a firmware-rejected destroy of (u64)-1
and a spurious error in dmesg.

mana_create_txq() has several error paths (after mana_alloc_queues() or
mana_create_wq_obj() failure) where tx_qp[i].tx_object stays as the
INVALID_MANA_HANDLE sentinel set at allocation. mana_destroy_txq() then
unconditionally calls mana_destroy_wq_obj() with (u64)-1, which firmware
rejects and logs an error.
Mirror the RX-side pattern in mana_destroy_rxq() and skip the destroy
when the handle is still INVALID_MANA_HANDLE.

mana_gd_create_mana_wq_cq() leaves queue->id as 0 (from kzalloc_obj())
until mana_create_wq_obj() assigns the firmware-returned id. If creation
fails before that, cleanup calls mana_gd_destroy_cq() with id 0, NULLing
gc->cq_table[0] and silently breaking whichever real CQ owns that slot.
Initialize queue->id to INVALID_QUEUE_ID right after allocation, matching
mana_gd_create_eq(). The existing (id >= max_num_cqs) guard then
short-circuits cleanly.

Victor Nogueira says:
====================
Avoid mistaken parent class deactivation during peek
Several qdiscs (fq_codel, codel and dualpi2) may drop packets while
peeking at their queue. When that happens they call
qdisc_tree_reduce_backlog() to notify the parent of the backlog/qlen
change. The problem is that they do so *before* reincrementing the qlen
that peek had temporarily decremented.
If the qlen momentarily drops to zero while peek still has an skb to
return, qdisc_tree_reduce_backlog() ends up invoking the parent's
qlen_notify() callback even though the child is not actually empty. The
parent then deactivates the class, while the child still holds a packet.
For parents such as QFQ this desync corrupts the active class list and
leads to wild memory accesses and NULL pointer dereferences (see the
per-patch splats). For HFSC it might lead to stalls [1].
Fix all three qdiscs the same way: only call qdisc_tree_reduce_backlog()
once the qlen has been restored, so the parent never observes a
transient empty child during peek.
Patch 1 fixes this for fq_codel, patch 2 for codel, patch 3 for dualpi2
and patch 4 adds test cases for these 3 setups.
Note: Patch 1 is one of two fixes for the stall reported in [1]; the
companion fix is "net/sched: sch_hfsc: Don't make class passive twice",
sent separately.
Note2: A possible cleaner fix is to create a new helper function for peek
that only calls qdisc_tree_reduce_backlog after reincrementing the qlen.
This would be called from the 3 vulnerable qdiscs, however we thought this
might make it harder for backporting so, if people agree, we can submit
this cleaner version to net-next after this one is merged.

socket/backlog synchronization and passes that raw pointer into

sets rx->backlog = NULL and frees the backlog rings, so a kernel
preallocation worker can keep using a freed struct rxrpc_backlog

listening or discarded the service backlog.

rxrpc_recvmsg_oob() takes a received oob message off recvmsg_oobq and,
if a response is needed, moves it onto the pending_oobq tree. However,
only the unlink from recvmsg_oobq is guarded by MSG_PEEK; the move onto
pending_oobq always runs.
As a result, reading a challenge with MSG_PEEK leaves the skb on
recvmsg_oobq while also adding it to pending_oobq. Since struct
sk_buff's rbnode shares storage with its next and prev pointers,
rb_insert_color() overwrites the list linkage, and the skb, which holds
a single reference, becomes reachable from both queues at once.
When the socket is closed both queues are drained in turn. While
draining recvmsg_oobq, __skb_unlink() follows the next and prev
pointers that rbnode has overwritten and writes to a bad address. Also,
as the skb holds a single reference but is freed from each queue, both
the skb and the connection reference it holds are released twice. This
leads to memory corruption and to a use-after-free caused by the
connection refcount underflow.
MSG_PEEK does not consume the message from the queue, so only unlink it
from recvmsg_oobq and then move it onto pending_oobq or free it when
the message is actually consumed.

rxrpc_recvmsg_data() calls rxrpc_verify_data() whenever the
rxrpc_call.rx_dec_buffer is unallocated and assumes that upon
successful return that rx_dec_buffer must be allocated.
However, rxrpc_verify_data() does not request an allocation if
the rxrpc_skb_priv.len is zero.
In addition, failure to allocate rx_dec_buffer will result in a
call to skb_copy_bits() with a NULL destination which can
trigger a NULL pointer dereference.
To prevent these issues rxrpc_verify_data() is modified to
always attempt to allocate the rxrpc_call.rx_dec_buffer if it
is NULL.
This issue was identified with assistance of a private
sashiko instance.

Currently the virtio_net driver exposes csum offload for UDP-tunneled,
TCP non GSO packets. Such packet reach the host as CSUM_PARTIAL ones
with the 'encapsulation' flag cleared, as the virtio specification do
not support this specific kind of offload.
HW NICs with UDP tunnel TSO support - and those drivers directly
accessing skb->csum_start/csum_offset - are still capable of computing
the needed csum correctly, but otherwise the packets reach the wire with
bad csum on both the inner and outer transport header.
Address the issue explicitly disabling csum offload for UDP tunneled,
