The Secondary Sample Point Source field has been
set to an incorrect value by some mistake in the
past
0b01 - SSP_SRC_NO_SSP - SSP is not used.
for data bitrates above 1 MBit/s. The correct/default
value already used for lower bitrates is
0b00 - SSP_SRC_MEAS_N_OFFSET - SSP position = TRV_DELAY
(Measured Transmitter delay) + SSP_OFFSET.
The related configuration register structure is described
in section 3.1.46 SSP_CFG of the CTU CAN FD
IP CORE Datasheet.
The analysis leading to the proper configuration
is described in section 2.8.3 Secondary sampling point
of the datasheet.
The change has been tested on AMD/Xilinx Zynq
with the next CTU CN FD IP core versions:
- 2.6 aka master in the "integration with Zynq-7000 system" test
6.12.43-rt12+ #1 SMP PREEMPT_RT kernel with CTU CAN FD git
driver (change already included in the driver repo)
- older 2.5 snapshot with mainline kernels with this patch
applied locally in the multiple CAN latency tester nightly runs
6.18.0-rc4-rt3-dut #1 SMP PREEMPT_RT
6.19.0-rc3-dut

In gs_can_open(), the URBs for USB-in transfers are allocated, added to the
parent->rx_submitted anchor and submitted. In the complete callback
gs_usb_receive_bulk_callback(), the URB is processed and resubmitted. In
gs_can_close() the URBs are freed by calling
usb_kill_anchored_urbs(parent->rx_submitted).
However, this does not take into account that the USB framework unanchors
the URB before the complete function is called. This means that once an
in-URB has been completed, it is no longer anchored and is ultimately not
released in gs_can_close().
Fix the memory leak by anchoring the URB in the
gs_usb_receive_bulk_callback() to the parent->rx_submitted anchor.

When es58x_alloc_rx_urbs() fails to allocate the requested number of
URBs but succeeds in allocating some, it returns an error code.
This causes es58x_open() to return early, skipping the cleanup label
'free_urbs', which leads to the anchored URBs being leaked.
As pointed out by maintainer Vincent Mailhol, the driver is designed
to handle partial URB allocation gracefully. Therefore, partial
allocation should not be treated as a fatal error.
Modify es58x_alloc_rx_urbs() to return 0 if at least one URB has been
allocated, restoring the intended behavior and preventing the leak
in es58x_open().

The max buffer size of ENETC RX BD is 0xFFFF bytes, so if the PAGE_SIZE
is greater than 128K, ENETC_RXB_DMA_SIZE and ENETC_RXB_DMA_SIZE_XDP will
be greater than 0xFFFF, thus causing a build warning.
This will not cause any practical issues because ENETC is currently only
used on the ARM64 platform, and the max PAGE_SIZE is 64K. So this patch
is only for fixing the build warning that occurs when compiling ENETC
drivers for other platforms.

NULL pointer dereference fix.
msg_get_inq is an input field from caller to callee. Don't set it in
the callee, as the caller may not clear it on struct reuse.
This is a kernel-internal variant of msghdr only, and the only user
does reinitialize the field. So this is not critical for that reason.
But it is more robust to avoid the write, and slightly simpler code.
And it fixes a bug, see below.
Callers set msg_get_inq to request the input queue length to be
returned in msg_inq. This is equivalent to but independent from the
SO_INQ request to return that same info as a cmsg (tp->recvmsg_inq).
To reduce branching in the hot path the second also sets the msg_inq.
That is WAI.
This is a fix to commit 4d1442979e ("af_unix: don't post cmsg for
SO_INQ unless explicitly asked for"), which fixed the inverse.
Also avoid NULL pointer dereference in unix_stream_read_generic if
state->msg is NULL and msg->msg_get_inq is written. A NULL state->msg
can happen when splicing as of commit 2b514574f7 ("net: af_unix:
implement splice for stream af_unix sockets").
Also collapse two branches using a bitwise or.

When bnxt_init_one() fails during initialization (e.g.,
bnxt_init_int_mode returns -ENODEV), the error path calls
bnxt_free_hwrm_resources() which destroys the DMA pool and sets
bp->hwrm_dma_pool to NULL. Subsequently, bnxt_ptp_clear() is called,
which invokes ptp_clock_unregister().
Since commit a60fc3294a ("ptp: rework ptp_clock_unregister() to
disable events"), ptp_clock_unregister() now calls
ptp_disable_all_events(), which in turn invokes the driver's .enable()
callback (bnxt_ptp_enable()) to disable PTP events before completing the
unregistration.
bnxt_ptp_enable() attempts to send HWRM commands via bnxt_ptp_cfg_pin()
and bnxt_ptp_cfg_event(), both of which call hwrm_req_init(). This
function tries to allocate from bp->hwrm_dma_pool, causing a NULL
pointer dereference:
bnxt_en 0000:01:00.0 (unnamed net_device) (uninitialized): bnxt_init_int_mode err: ffffffed

In __sta_info_destroy_part2(), station statistics are requested after the
IEEE80211_STA_NONE -> IEEE80211_STA_NOTEXIST transition. This is
problematic because the driver may be unable to handle the request due to
the STA being in the NOTEXIST state (i.e. if the driver destroys the
underlying data when transitioning to NOTEXIST).
Move the statistics collection to before the state transition to avoid
this issue.

During the transition to use channel contexts throughout, the
ability to do injection while in monitor mode concurrent with
another interface was lost, since the (virtual) monitor won't
have a chanctx assigned in this scenario.
It's harder to fix drivers that actually transitioned to using
channel contexts themselves, such as mt76, but it's easy to do
those that are (still) just using the emulation. Do that.

`i2c_hid_xfer` is used to read `recv_len + sizeof(__le16)` bytes of data
into `ihid->rawbuf`.
The former can come from the userspace in the hidraw driver and is only
bounded by HID_MAX_BUFFER_SIZE(16384) by default (unless we also set
`max_buffer_size` field of `struct hid_ll_driver` which we do not).
The latter has size determined at runtime by the maximum size of
different report types you could receive on any particular device and
can be a much smaller value.
Fix this by truncating `recv_len` to `ihid->bufsize - sizeof(__le16)`.
The impact is low since access to hidraw devices requires root.

net: netdevsim: fix inconsistent carrier state after link/unlink
This series fixes netdevsim's inconsistent behavior between carrier
and link/unlink state.
More specifically, this fixes a bug that the carrier goes DOWN although
two netdevsim were peered, depending on the order of peering and ifup.
Especially in a NetworkManager-enabled environment, netdevsim test fails
because of this.
The first patch fixes the bug itself in netdevsim/bus.c by adding
netif_carrier_on() into a proper function. The second patch adds a
regression test for this bug.

This commit adds a test case for netdevsim carrier state consistency.
Specifically, the added test verifies the carrier state during the
following operations:
1. Unlink two netdevsims
2. ifdown one netdevsim, then ifup again
3. Link the netdevsims again
4. ifdown one netdevsim, then ifup again
These steps verifies that the carrier is UP iff two netdevsims are
linked and ifuped.

This patch fixes the edge case behavior on ifup/ifdown and
linking/unlinking two netdevsim interfaces:
1. unlink two interfaces netdevsim1 and netdevsim2
2. ifdown netdevsim1
3. ifup netdevsim1
4. link two interfaces netdevsim1 and netdevsim2
5. (Now two interfaces are linked in terms of netdevsim peer, but
carrier state of the two interfaces remains DOWN.)
This inconsistent behavior is caused by the current implementation,
which only cares about the "link, then ifup" order, not "ifup, then
link" order. This patch fixes the inconsistency by calling
netif_carrier_on() when two netdevsim interfaces are linked.
This patch fixes buggy behavior on NetworkManager-based systems which
causes the netdevsim test to fail with the following error:
# timeout set to 600
# selftests: drivers/net/netdevsim: peer.sh
# 2025/12/25 00:54:03 socat[9115] W address is opened in read-write mode but only supports read-only

This patch also solves timeout on TCP Fast Open (TFO) test in
NetworkManager-based systems because it also depends on netdevsim's
carrier consistency.

The reason why it is broken beyond repair in this form is that the
mv88e6xxx driver outsources its "tx-p2p-microvolt" property to the OF
node of an external Ethernet PHY. This:
(a) does not work if there is no external PHY (chip-to-chip connection,
or SFP module)
(b) pollutes the OF property namespace / bindings of said external PHY
("tx-p2p-microvolt" could have meaning for the Ethernet PHY's SerDes
interface as well)
We can revisit the idea of making SerDes amplitude configurable once we
have proper bindings for the mv88e6xxx SerDes. Until then, remove the
code that leaves us with unnecessary baggage.
