eb7b4d458e devlink: Implement devlink param multi attribute nested data values
Devlink param value attribute is not defined since devlink is handling
the value validating and parsing internally, this allows us to implement
multi attribute values without breaking any policies.

Devlink param multi-attribute values are considered to be dynamically
sized arrays of u64 values, by introducing a new devlink param type
DEVLINK_PARAM_TYPE_U64_ARRAY, driver and user space can set a variable
count of u64 values into the DEVLINK_ATTR_PARAM_VALUE_DATA attribute.

Implement get/set parsing and add to the internal value structure passed
to drivers.

This is useful for devices that need to configure a list of values for
a specific configuration.

example:
$ devlink dev param show pci/... name multi-value-param
name multi-value-param type driver-specific
values:
cmode permanent value: 0,1,2,3,4,5,6,7

$ devlink dev param set pci/... name multi-value-param \
		value 4,5,6,7,0,1,2,3 cmode permanent

9375487c0c dpll: add generic DPLL type
Add DPLL_TYPE_GENERIC to represent DPLL devices which do not fit the
existing PPS or EEC classes.

The UAPI type is intentionally generic. During netdev discussion,
maintainers pointed out that introducing identifiers tied to a specific
placement or single design does not scale across ASICs and vendors.
The role of a DPLL is already inferable from the spawning driver,
bus device, and pin topology, without encoding additional
purpose-specific taxonomy in the type name.

Using a generic type keeps the UAPI extensible and avoids premature
naming that may become incorrect as new hardware topologies are
exposed through the DPLL subsystem.

Expose the new type through UAPI and netlink specification as "generic".

====================
pull request (net-next): ipsec-next 2026-06-12

1) Replace the open-coded manual cleanup in xfrm_add_policy() error
   path with xfrm_policy_destroy() for consistency with
   xfrm_policy_construct().
   From Deepanshu Kartikey.

2) Limit XFRMA_TFCPAD to a sensible maximum (max IP length, 64k) since
   u32 is excessive for traffic flow confidentiality padding.
   From David Ahern.

3) Add a new netlink message XFRM_MSG_MIGRATE_STATE that
   allows migrating individual IPsec SAs independently of
   their policies. The existing XFRM_MSG_MIGRATE is tightly coupled
   to policy+SA migration, lacks SPI for unique SA identification,
   and cannot express reqid changes or migrate Transport mode
   selectors. The new interface identifies the SA via SPI and mark,
   supports reqid changes, address family changes, encap removal,
   and uses an atomic create+install flow under x->lock to prevent
   SN/IV reuse during AEAD SA migration.
   From Antony Antony.

06c2dce2d0 psp: add new netlink cmd for dev-assoc and dev-disassoc
The main purpose of this cmd is to be able to associate a
non-psp-capable device (e.g. veth or netkit) with a psp device.
One use case is if we create a pair of veth/netkit, and assign 1 end
inside a netns, while leaving the other end within the default netns,
with a real PSP device, e.g. netdevsim or a physical PSP-capable NIC.
With this command, we could associate the veth/netkit inside the netns
with PSP device, so the virtual device could act as PSP-capable device
to initiate PSP connections, and performs PSP encryption/decryption on
the real PSP device.

Introduce 2 versions of psp_device_get_locked:
1. psp_device_get_locked_admin(): This version is used for operations
   that would change the status of the psd, and are currently used for
   dev-set and key-rotation.
2. psp_device_get_locked(): This is the non-admin version, which are
   used for broader user issued operations including: dev-get, rx-assoc,
   tx-assoc, get-stats.

81246a6530 handshake: Require admin permission for DONE command
ACCEPT and DONE are the two downcalls of the handshake genl
family, both intended for use by the trusted handshake agent
(tlshd). ACCEPT already requires GENL_ADMIN_PERM; DONE has
no privilege check at all.

The fd-lookup in handshake_nl_done_doit() only confirms that
some pending handshake request exists for the supplied sockfd;
it does not authenticate the sender. An unprivileged process
that guesses or observes a valid sockfd can therefore submit
a DONE with HANDSHAKE_A_DONE_STATUS == 0, leaving the kernel
consumer to proceed as if the handshake succeeded. A non-zero
status on a forged DONE tears down a legitimate in-flight
handshake before tlshd can report its real result.

30ff28fdc4 mptcp: introduce add_addr_v6_port_drop_ts sysctl knob
This sysctl is going to be used in the next commits to drop TCP
timestamps option, to be able to send an ADD_ADDR with a v6 IP address
and a port number. It is enabled by default.

This knob is explicitly disabled in the MPTCP Join selftest, with the
"signal addr list progresses after tx drop" subtest, to continue
verifying the previous behaviour where the ADD_ADDR is not sent due to a
lack of space.

While at it, move syn_retrans_before_tcp_fallback down from struct
mptcp_pernet, to avoid creating another 3 bytes hole.

32b0b89533 bonding: 3ad: add lacp_strict configuration knob
When an 802.3ad (LACP) bonding interface has no slaves in the
collecting/distributing state, the bonding master still reports
carrier as up as long as at least 'min_links' slaves have carrier.

In this situation, only one slave is effectively used for TX/RX,
while traffic received on other slaves is dropped. Upper-layer
daemons therefore consider the interface operational, even though
traffic may be blackholed if the lack of LACP negotiation means
the partner is not ready to deal with traffic.

Introduce a configuration knob to control this behavior. It allows
the bonding master to assert carrier only when at least 'min_links'
slaves are in Collecting_Distributing state.

The default mode preserves the existing behavior. This patch only
introduces the knob; its behavior is implemented in the subsequent
commit.

Netfilter/IPVS updates for net-next

The following patchset contains Netfilter/IPVS updates for net-next,
this contains updates to address sashiko reports in IPVS and Netfilter
on possible pre-existing issues. This also includes a series to add
refcount for ct helper and timeout to deal with a corner case scenario
with unconfirmed conntracks flying to nfqueue.

1) Add a conn_max sysctl to IPVS to limit the maximum number of
   connections, from Julian Anastasov.

2) Use get_unaligned_be16() to access TCP MSS in nfnetlink_osf,
   from Fernando Fernandez Mancera.

3) Use {READ,WRITE}_ONCE to access helper flags from nfnetlink_helper.

Several patches for the synproxy infrastructure, from Fernando
Fernandez Mancera:

4) Drop packet if TCP timestamp adjustment fails.

5) Continue parsing of TCP timestamp to deal with possible duplicates.

6) Use {get,put}_unaligned_be32() to acess the TCP timestamp.

7) Hold ct->lock to initialize nf_ct_seqadj_init().

Updates for the ct timeout infrastructure, to deal with a corner case
for unconfirmed conntracks flying to nfqueue:

8) Add a refcount to track ct timeout policy use by ct extension,
   release the timeout until the last ct extension drops the refcnt
   on it.

Similar update for the ct helper infrastructure:

9) Dynamic allocation of ct helpers, as a preparation for adding
   refcount to track ct extension use.

10) Move destroy_sibling_or_exp() to nf_conntrack_proto_gre, so
    pptp conntrack helper module removal does not make this code
    unreachable via the helper->destroy callback. This is another
    dependency for the new refcount coming in this series.

11) Add a refcount to track use of it from the ct extension, then
    ct helper and timeout is reachable to the connection until
    it goes away.

12) Remove the genid infrastructure in ct extensions. The primary
    goal was to detect that a ct extension such as ct timeout and
    ct helper went stale for unconfirmed conntrack, either because
    object or module was removed. This deactivates all ct extensions
    though for this unconfirmed conntrack.

13) Call nf_ct_gre_keymap_destroy() if this is a master conntrack
    with a pptp helper only.

sashiko.dev reports one more relevant issue when unsetting the helper
via ctnetlink that I will address in a follow up patch.

Then, two more assorted updates:

14) Avoid a unlikely underflow in bridge VLAN untag, only possible
    if buggy bridge VLAN filtering is buggy, remove WARN_ON_ONCE
    while at it. From David Carlier.

15) Use get_unaligned_be32() in nf_conntrack_tcp to access sack
    extension, from Rosen Penev.

e302aa3d00 net: devmem: allow bind-rx from non-init user namespaces
NETDEV_CMD_BIND_RX is currently GENL_ADMIN_PERM, which checks
CAP_NET_ADMIN against init userns. With recent container/netkit/ns
support for devmem, other userns/netns use cases come online and require
bind-rx to allow CAP_NET_ADMIN in non-init user ns as well.

Switch the flag to GENL_UNS_ADMIN_PERM to allow bind-rx for
CAP_NET_ADMIN in the netns's owning userns as well.

4a15044a2b ipvs: add conn_max sysctl to limit connections
Currently, we are using atomic_t to track the number of
connections. On 64-bit setups with large memory there is
a risk this counter to overflow. Also, setups with many
containers may need to tune the limit for connections.

Add sysctl control to limit the number of connections to
1,073,741,824 (64-bit) and 16,777,216 (32-bit).
Depending on the admin's privilege, the value is
used to change a soft or hard limit allowing
unprivileged admins to change the soft limit in
range determined by privileged admins.

afabbb56a7 geneve: Introduce IFLA_GENEVE_LOCAL and IFLA_GENEVE_LOCAL6.
By default, a GENEVE device bind()s its underlying UDP socket(s) to
the IPv4 or IPv6 wildcard address because there is no way to specify
a specific local IP address to bind() to.

This prevents deploying multiple GENEVE devices on a multi-homed host
where each device should be isolated and bound to a different local IP
address on the same UDP port.

Let's introduce new options, IFLA_GENEVE_LOCAL and IFLA_GENEVE_LOCAL6,
to allow specifying a local IPv4/IPv6 address for the backend UDP
socket.

By default, when collect metadata mode (IFLA_GENEVE_COLLECT_METADATA)
is enabled, both IPv4 and IPv6 sockets are created.  However, if a
source address is specified via the new attributes, only a single
socket corresponding to that specific address family is created.

Accordingly, geneve_find_sock() and geneve_find_dev() are updated to
take the source address into account, ensuring that multiple devices
and sockets configured with different source addresses can coexist
without conflict.

In addition, the source address is validated in geneve_xmit_skb()
and geneve6_xmit_skb(), so the BPF prog must set it in bpf_tunnel_key.

With this change, multiple GENEVE devices can be successfully created
and bound to their respective local IP addresses:

  (*) "local" is the keyword for IFLA_GENEVE_LOCAL / IFLA_GENEVE_LOCAL6

  # for i in $(seq 1 2);
  do
          ip link add geneve4_${i} type geneve local 192.168.0.${i} external
          ip addr add 192.168.0.${i}/24 dev geneve4_${i}
          ip link set geneve4_${i} up

          ip link add geneve6_${i} type geneve local 2001:9292::${i} external
          ip addr add 2001:9292::${i}/64 dev geneve6_${i} nodad
          ip link set geneve6_${i} up
  done

  # ip -d l | grep geneve
  9: geneve4_1: <BROADCAST,MULTICAST,UP,LOWER_UP> ...
      geneve external id 0 local 192.168.0.1 ...
  10: geneve6_1: <BROADCAST,MULTICAST,UP,LOWER_UP> ...
      geneve external id 0 local 2001:9292::1 ...
  11: geneve4_2: <BROADCAST,MULTICAST,UP,LOWER_UP> ...
      geneve external id 0 local 192.168.0.2 ...
  12: geneve6_2: <BROADCAST,MULTICAST,UP,LOWER_UP> ...
      geneve external id 0 local 2001:9292::2 ...

  # ss -ua | grep geneve
  UNCONN 0      0         192.168.0.2:geneve      0.0.0.0:*
  UNCONN 0      0         192.168.0.1:geneve      0.0.0.0:*
  UNCONN 0      0      [2001:9292::2]:geneve            *:*
  UNCONN 0      0      [2001:9292::1]:geneve            *:*

Note that even if the local address is explicitly configured with
the wildcard address, kernel does not dump it except for devices with
IFLA_GENEVE_COLLECT_METADATA.  This is consistent with the behaviour
of is_tnl_info_zero(), which treats the wildcard remote address as not
configured.

384cc80f30 wifi: rtw89: usb: add serial_number and uuid sysfs attributes for 0x28de:0x2432
Expose the device's Serial Number (SN) and UUID from EFUSE via two
read-only sysfs attributes, `serial_number` and `uuid`, on the ieee80211
phy device under the `rtw89_usb` attribute group.

This hardware identification information is essential for user-space
applications to uniquely identify, track, and manage specific Wi-Fi
adapters. For example, in automated factory provisioning or device
management systems, user-space tools rely on the EFUSE serial number and
UUID to bind configurations to specific physical adapters. Currently,
standard wireless APIs do not expose this low-level hardware
information, making these sysfs nodes the only viable solution for
user space to extract this data.

The attributes are gated behind a new RTW89_QUIRK_HW_INFO_SYSFS quirk,
enabled only for the VID 0x28de / PID 0x2432 device via the
dev_id_quirks field in rtw89_driver_info.

Example usage from user-space:
  $ cat /sys/class/ieee80211/phy0/rtw89_usb/serial_number
  3642000123
  $ cat /sys/class/ieee80211/phy0/rtw89_usb/uuid

Pull USB and Thunderbolt fixes from Greg KH:
 "Here is a set of USB fixes and new device ids for 7.1-rc6. Nothing
  major in here, just lots of tiny fixes for reported issues found by
  users and some older patches found by some scanning tools. Included in
  here are:

   - typec fixes found by fuzzers that have decided to finally look at
     that device interaction path (i.e. before a driver is bound to a
     device)

   - typec fixes for issues found by users

   - thunderbolt driver fixes for reported problems

   - cdns3 driver fixes

   - dwc3 driver fixes

   - new device quirks added

   - usb serial driver fixes for broken devices

   - other small driver fixes

  All of these have been in linux-next for over a week with no reported
  issues"

Pull spi fixes from Mark Brown:
 "One substantive fix here, fixing corruption of the maximum frequency
  for spi-mem operations which caused users to remember what should have
  been a temporarily modified maximum frequency as the standard going
  forward, potentially causing instability when the modification raised
  rather than lowered the frequency.

  We also have a trivial patch which just documents the correct way to
  describe the Qualcomm IPQ5210 SNAND controller in the DT, there are no

ac0056e4f1 docs: page_pool: drop the mention of the legacy stats API
The Netlink support for querying page pool stats has been
proven out in production, let's remove the mention of the
helper meant for dumping page pool stats into ethtool -S
from the docs.

Call out in the kdoc that this API is deprecated.
Some drivers may not be able to use the Netlink API
(if page pool is shared across netdevs). So the old API
is not _completely_ dead. But we shouldn't advertise it.

The flag was removed in commit 09d96ee567 ("page_pool: remove
PP_FLAG_PAGE_FRAG"), but the documentation still mentions it when
describing fragment usage. Drop the stale reference; the fragment
API does not require any opt-in flag.

Qualcomm driver fixes for v7.1

The Qualcomm ICE driver suffers from race conditions between probe() and
get() and will in certain cases return the wrong error code, which
results in storage drivers failing to probe. Fix these issues.

Also correct the DeviceTree binding, to ensure that relevant clocks are
described and voted for, to prevent the driver from accessing unclocked
hardware during boot.

6686e7f03f docs: net: add Rx notes to the checksum guide
The Rx checksum processing gives people pause. The two main questions
in my experience are:
 - what to do with bad IPv4 checksum; and
 - what to do with packets with bad checksum.

Folks often feel the urge to drop the latter, to "avoid overloading
the host".
