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

net: do not write to msg_get_inq in callee
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
4d1442979e4a ("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
2b514574f7e8 ("net: af_unix:
implement splice for stream af_unix sockets").
Also collapse two branches using a bitwise or.

bnxt_en: Fix NULL pointer crash in bnxt_ptp_enable during error cleanup
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
a60fc3294a37 ("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:

net/sched: sch_qfq: Fix NULL deref when deactivating inactive aggregate in qfq_reset
`qfq_class->leaf_qdisc->q.qlen > 0` does not imply that the class
itself is active.
Two qfq_class objects may point to the same leaf_qdisc. This happens
when:
1. one QFQ qdisc is attached to the dev as the root qdisc, and
2. another QFQ qdisc is temporarily referenced (e.g., via qdisc_get()
/ qdisc_put()) and is pending to be destroyed, as in function
tc_new_tfilter.
When packets are enqueued through the root QFQ qdisc, the shared
leaf_qdisc->q.qlen increases. At the same time, the second QFQ
qdisc triggers qdisc_put and qdisc_destroy: the qdisc enters
qfq_reset() with its own q->q.qlen == 0, but its class's leaf
qdisc->q.qlen > 0. Therefore, the qfq_reset would wrongly deactivate
an inactive aggregate and trigger a null-deref in qfq_deactivate_agg:

The framer driver defines framer_pm_runtime_put() to return an int,
but that return value is never used. It also passes the return value
of pm_runtime_put() to the caller which is not very useful.
Returning an error code from pm_runtime_put() merely means that it has
not queued up a work item to check whether or not the device can be
suspended and there are many perfectly valid situations in which that
can happen, like after writing "on" to the devices' runtime PM "control"
attribute in sysfs for one example.
Modify phy_pm_runtime_put() to discard the pm_runtime_put() return

No intentional functional impact.

wifi: mac80211: collect station statistics earlier when disconnect
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.

wifi: mac80211: restore non-chanctx injection behaviour
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.

====================
net: phy: realtek: various improvements for 2.5GE PHYs
This series improves the RealTek PHY driver, mostly for 2.5GE PHYs.
It implements configuring SGMII and 2500Base-X in-band auto-negotiation
and improves using the PHYs in Clause-22-only mode.
Note that the rtl822x_serdes_write() function introduced by this series
is going to be reused to configure polarities of SerDes RX and TX lanes
once series "PHY polarity inversion via generic device tree properties"
has been applied.
Access to other registers on MDIO_MMD_VEND2 is important for more than
just configuring autonegotiation, it is also used to setup ALDPS or to
disable the PHY responding to the MDIO broadcast address 0. Both will be
implemented by follow-up patches.
The address translation function for registers on MDIO_MMD_VEND2 into
paged registers can potentially also be used to describe other paged
access in a more consistent way, but that mostly makes sense on PHYs
which also support Clause-45, so this series doesn't convert all the
existing paged access on RealTek's 1GE PHYs which do not support
Clause-45.

HID: i2c-hid: fix potential buffer overflow in i2c_hid_get_report()
`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.

net: netdevsim: fix inconsistent carrier state after link/unlink
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

net: wwan: mhi: Add network support for Foxconn T99W760
T99W760 is designed based on Qualcomm SDX35 chip. It use similar
architecture with SDX72/SDX75 chip. So we need to assign initial
link id for this device to make sure network available.

selftests: hw-net: rss-input-xfrm: try to enable the xfrm at the start
The test currently SKIPs if the symmetric RSS xfrm is not enabled
by default. This leads to spurious SKIPs in the Intel CI reporting
results to NIPA.

Revert "dsa: mv88e6xxx: make serdes SGMII/Fiber tx amplitude configurable"
This reverts commit
926eae604403acfa27ba5b072af458e87e634a50, which
never could have produced the intended effect:
https://lore.kernel.org/netdev/AM0PR06MB10396BBF8B568D77556FC46F8F7DEA@AM0PR06MB10396.eurprd06.prod.outlook.com/
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.

ipv6: preserve insertion order for same-scope addresses
IPv6 addresses with the same scope are returned in reverse insertion
order, unlike IPv4. For example, when adding a -> b -> c, the list is
reported as c -> b -> a, while IPv4 preserves the original order.
This behavior causes:
a. When using `ip -6 a save` and `ip -6 a restore`, addresses are restored
in the opposite order from which they were saved. See example below
showing addresses added as 1::1, 1::2, 1::3 but displayed and saved
in reverse order.
# ip -6 a a 1::1 dev x
# ip -6 a a 1::2 dev x
# ip -6 a a 1::3 dev x
# ip -6 a s dev x
2: x: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
inet6 1::3/128 scope global tentative
valid_lft forever preferred_lft forever
inet6 1::2/128 scope global tentative
valid_lft forever preferred_lft forever
inet6 1::1/128 scope global tentative
valid_lft forever preferred_lft forever
# ip -6 a save > dump
# ip -6 a d 1::1 dev x
# ip -6 a d 1::2 dev x
# ip -6 a d 1::3 dev x
# ip a d ::1 dev lo
# ip a restore < dump
# ip -6 a s dev x
2: x: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
inet6 1::1/128 scope global tentative
valid_lft forever preferred_lft forever
inet6 1::2/128 scope global tentative
valid_lft forever preferred_lft forever
inet6 1::3/128 scope global tentative
valid_lft forever preferred_lft forever
# ip a showdump < dump
if1:
inet6 ::1/128 scope host proto kernel_lo
valid_lft forever preferred_lft forever
if2:
inet6 1::3/128 scope global tentative
valid_lft forever preferred_lft forever
if2:
inet6 1::2/128 scope global tentative
valid_lft forever preferred_lft forever
if2:
inet6 1::1/128 scope global tentative
valid_lft forever preferred_lft forever
b. Addresses in pasta to appear in reversed order compared to host
addresses.
The ipv6 addresses were added in reverse order by commit
e55ffac60117
("[IPV6]: order addresses by scope"), then it was changed by commit
502a2ffd7376 ("ipv6: convert idev_list to list macros"), and restored by
commit
b54c9b98bbfb ("ipv6: Preserve pervious behavior in
ipv6_link_dev_addr()."). However, this reverse ordering within the same
scope causes inconsistency with IPv4 and the issues described above.
This patch aligns IPv6 address ordering with IPv4 for consistency
by changing the comparison from >= to > when inserting addresses
into the address list. Also updates the ioam6 selftest to reflect
the new address ordering behavior. Combine these two changes into
one patch for bisectability.
