If alloc_skb() fails in pad_compress_skb(), it returns NULL without
releasing the old skb. The caller does:
skb = pad_compress_skb(ppp, skb);
if (!skb)
goto drop;
drop:
kfree_skb(skb);
When pad_compress_skb() returns NULL, the reference to the old skb is
lost and kfree_skb(skb) ends up doing nothing, leading to a memory leak.
Align pad_compress_skb() semantics with realloc(): only free the old
skb if allocation and compression succeed. At the call site, use the
new_skb variable so the original skb is not lost when pad_compress_skb()
fails.

This new attribute is supposed to be used instead of NFTA_DEVICE_NAME
for simple wildcard interface specs. It holds a NUL-terminated string
representing an interface name prefix to match on.
While kernel code to distinguish full names from prefixes in
NFTA_DEVICE_NAME is simpler than this solution, reusing the existing
attribute with different semantics leads to confusion between different
versions of kernel and user space though:
* With old kernels, wildcards submitted by user space are accepted yet
silently treated as regular names.
* With old user space, wildcards submitted by kernel may cause crashes
since libnftnl expects NUL-termination when there is none.
Using a distinct attribute type sanitizes these situations as the
receiving part detects and rejects the unexpected attribute nested in
*_HOOK_DEVS attributes.

Bernard Pidoux reported a regression apparently caused by commit
c353e8983e ("net: introduce per netns packet chains").
skb->dev becomes NULL and we crash in __netif_receive_skb_core().
Before above commit, different kind of bugs or corruptions could happen
without a major crash.
But the root cause is that ax25_kiss_rcv() can queue/mangle input skb
without checking if this skb is shared or not.
Many thanks to Bernard Pidoux for his help, diagnosis and tests.

In mctp_getsockopt(), unrecognized options currently return -EINVAL.
In contrast, mctp_setsockopt() returns -ENOPROTOOPT for unknown

Update mctp_getsockopt() to also return -ENOPROTOOPT for unknown

Currently SMC code is validating the reserved bits while parsing the incoming
CLC decline message & when this validation fails, its treated as a protocol
error. As a result, the SMC connection is terminated instead of falling back to
TCP. As per RFC7609[1] specs we shouldn't be validating the reserved bits that
is part of CLC message. This patch fixes this issue.
CLC Decline message format can viewed here[2].

The blamed commit added code which could return an error after we
requested the PHY interrupt. When we return an error, the caller
will call phy_detach() which fails to free the interrupt.
Rearrange the code such that failing operations happen before the
interrupt is requested, thereby allowing phy_detach() to be used.
Note that replacing phy_detach() with phy_disconnect() in these
paths could lead to freeing an interrupt which was never requested.

Intel Wired LAN Driver Updates 2025-09-02 (ice, idpf, i40e, ixgbe, e1000e)
For ice:
Jake adds checks for initialization of Tx timestamp tracking structure
to prevent NULL pointer dereferences.
For idpf:
Josh moves freeing of auxiliary device id to prevent use-after-free issue.
Emil sets, expected, MAC type value when sending virtchnl add/delete MAC
commands.

Jake removes read debugfs access as 'netdev_ops' has the possibility to
overflow.
Zhen Ni adds handling for when MAC list is empty.
For ixgbe:
Alok Tiwari corrects bitmap being used for link speeds.
For e1000e:
Vitaly adds check to ensure overflow does not occur in
e1000_set_eeprom().

Followup of commit c51da3f7a1 ("net: remove sock_i_uid()")
A recent syzbot report was the trigger for this change.
Over the years, we had many problems caused by the
read_lock[_bh](&sk->sk_callback_lock) in sock_i_uid().
We could fix smc_diag_dump_proto() or make a more radical move:
Instead of waiting for new syzbot reports, cache the socket
inode number in sk->sk_ino, so that we no longer
need to acquire sk->sk_callback_lock in sock_i_ino().
This makes socket dumps faster (one less cache line miss,
and two atomic ops avoided).
Prior art:
commit 25a9c8a443 ("netlink: Add __sock_i_ino() for __netlink_diag_dump().")
commit 4f9bf2a2f5 ("tcp: Don't acquire inet_listen_hashbucket::lock with disabled BH.")

The blamed commit introduced the concept of split attribute
counting, and later allocating an array to hold them, however
TypeArrayNest wasn't updated to use the new counting variable.
Abbreviated example from tools/net/ynl/generated/nl80211-user.c:
nl80211_if_combination_attributes_parse(...):
unsigned int n_limits = 0;
[...]
ynl_attr_for_each(attr, nlh, yarg->ys->family->hdr_len)
if (type == NL80211_IFACE_COMB_LIMITS)
ynl_attr_for_each_nested(attr2, attr)
dst->_count.limits++;
if (n_limits) {
dst->_count.limits = n_limits;
/* allocate and parse attributes */
}
In the above example n_limits is guaranteed to always be 0,
hence the conditional is unsatisfiable and is optimized out.
This patch changes the attribute counting to use n_limits++ in the
attribute counting loop in the above example.

These are mainly devicetree fixes for the rockchip and nxp platforms on
arm64, addressing mistakes in the board and soc specific descriptions.
In particular the newly added Rock 5T board required multiple bugfixes for
PCIe and USB, while on the i.MX platform there are a number of regulator
related fixes. The only other platforms with devicetree fixes are at91
with a fixup for SD/MMC and a change to enable all the available UARTS
on the Axiado reference board.
Also on the at91 platform, a Kconfig change addresses a regression that
stopped the DMA engine from working in 6.17-rc.
Three drivers each have a simple bugfix, stopping incorrect behavior in
op-tee firmware, the tee subsystem and the qualcomm mdt_loader.
Two trivial MAINTAINERS file changes are needed to make sure that
patches reach the correct maintainer, but don't change the actual

Fix sched_numa_find_nth_cpu() if mask offline
sched_numa_find_nth_cpu() uses a bsearch to look for the 'closest'
CPU in sched_domains_numa_masks and given cpus mask. However they
might not intersect if all CPUs in the cpus mask are offline. bsearch
will return NULL in that case, bail out instead of dereferencing a

PCIe and USB actually work, because the PCIe does share its lanes between
two ports and the usb needs to toggle a gpio to supply power.
The other interesting fix is the headphone detection on the Orange Pi 5+.
The rest are some added supplies to make the boot log less scary and a
number of styling fixes.

The newly added Rock 5T board needed slightly bigger fixes to make the
PCIe and USB actually work, because the PCIe does share its lanes between
two ports and the usb needs to toggle a gpio to supply power.
The other interesting fix is the headphone detection on the Orange Pi 5+.
The rest are some added supplies to make the boot log less scary and a
number of styling fixes.

error: '__memcpy()' 'cfg->s[i]->str' copy overflow (512 vs 65537)
This patch introduces size check before accessing the memory buffer.
The checks are base on the WID type of received data from the firmware.
For WID string configuration, the size limit is determined by individual

of 'struct wilc_cfg_str'.

Fix multiple fwnode reference leaks:
1. The function calls fwnode_get_named_child_node() to get the "leds" node,

2. Within the fwnode_for_each_child_node() loop, the early return
paths that don't properly release the "led" fwnode reference.

vxlan: Fix NPDs when using nexthop objects
With FDB nexthop groups, VXLAN FDB entries do not necessarily point to
a remote destination but rather to an FDB nexthop group. This means that
first_remote_{rcu,rtnl}() can return NULL and a few places in the driver
were not ready for that, resulting in NULL pointer dereferences.
Patches #1-#2 fix these NPDs.
Note that vxlan_fdb_find_uc() still dereferences the remote returned by
first_remote_rcu() without checking that it is not NULL, but this
function is only invoked by a single driver which vetoes the creation of
FDB nexthop groups. I will patch this in net-next to make the code less
fragile.
Patch #3 adds a selftests which exercises these code paths and tests
basic Tx functionality with FDB nexthop groups. I verified that the test
crashes the kernel without the first two patches.

When the "proxy" option is enabled on a VXLAN device, the device will
suppress ARP requests and IPv6 Neighbor Solicitation messages if it is
able to reply on behalf of the remote host. That is, if a matching and
valid neighbor entry is configured on the VXLAN device whose MAC address
is not behind the "any" remote (0.0.0.0 / ::).
The code currently assumes that the FDB entry for the neighbor's MAC
address points to a valid remote destination, but this is incorrect if
the entry is associated with an FDB nexthop group. This can result in a
NPD [1][3] which can be reproduced using [2][4].
Fix by checking that the remote destination exists before dereferencing
it.

VXLAN FDB entries can point to either a remote destination or an FDB
nexthop group. The latter is usually used in EVPN deployments where
learning is disabled.
However, when learning is enabled, an incoming packet might try to
refresh an FDB entry that points to an FDB nexthop group and therefore
does not have a remote. Such packets should be dropped, but they are
only dropped after dereferencing the non-existent remote, resulting in a
NPD [1] which can be reproduced using [2].
Fix by dropping such packets earlier. Remove the misleading comment from
first_remote_rcu().

Correct the Mode Control Register (MODCTRL) offset for RZ/N MIIC.
According to the R-IN Engine and Ethernet Peripherals Manual (Rev.1.30)
[0], Table 10.1 "Ethernet Accessory Register List", MODCTRL is at offset
0x8, not 0x20 as previously defined.
Offset 0x20 actually maps to the Port Trigger Control Register (PTCTRL),
which controls PTP_MODE[3:0] and RGMII_CLKSEL[4]. Using this incorrect
definition prevented the driver from configuring the SW_MODE[4:0] bits
in MODCTRL, which control the internal connection of Ethernet ports. As
a result, the MIIC could not be switched into the correct mode, leading
to link setup failures and non-functional Ethernet ports on affected
systems.

net: fix optical SFP failures
A regression was reported back in April concerning pcs-lynx and 10G
optical SFPs. This patch series addresses that regression, and likely
similar unreported regressions.
These patches:
- Add phy_interface_weight() which will be used in the solution.
- Split out the code that determines the inband "type" for an
interface mode.
- Clear the Autoneg bit in the advertising mask, or the Autoneg bit
in the support mask and the entire advertising mask if the selected
interface mode has no inband capabilties.
Tested with the mvpp2 patch posted earlier today.

Mathew reports that as a result of commit 6561f0e547 ("net: pcs:
pcs-lynx: implement pcs_inband_caps() method"), 10G SFP modules no
longer work with the Lynx PCS.
This problem is not specific to the Lynx PCS, but is caused by commit
df874f9e52 ("net: phylink: add pcs_inband_caps() method") which added
validation of the autoneg state to the optical SFP configuration path.
Fix this by handling interface modes that fundamentally have no
inband negotiation more correctly - if we only have a single interface
mode, clear the Autoneg support bit and the advertising mask. If the
module can operate with several different interface modes, autoneg may
be supported for other modes, so leave the support mask alone and just
clear the Autoneg bit in the advertising mask.
This restores 10G optical module functionality with PCS that supply
their inband support, and makes ethtool output look sane.
