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.

Because LLC wasn't complicated/annoying enough, there's 2 more
"ethertypes" being used for it:
- 0x8870 is pretty "normal", it got standardized in
802.1AC-2016/Cor1-2018 for transporting LLC frames > 1500 bytes.
It simply replaces the length value (which is no longer encoded, and
must now be derived from the packet.) The actual value dates back to
2001; https://datatracker.ietf.org/doc/html/draft-ietf-isis-ext-eth-01
(it was used without "proper" standardization for a long time)
- 0x00fe is a doozy - actually "invalid" depending on how you look at
it; it's used in GRE (and possibly GENEVE) tunnels to transport the
IS-IS routing protocol. https://seclists.org/tcpdump/2002/q4/61 is
the best/oldest source I could find. It's inspired by the 0xfe SAP
value, a GRE packet with protocol 0x00fe is followed by a payload "as
if" it was Ethernet with "<length> 0xfe 0xfe 0x03". (Again the length
isn't encoded explicitly anymore.)
The 0x00fe value is quite close to other values the kernel is using
internally for various things (after all they "won't clash for 1500
types"). Except this one does clash, and if someone unknowingly starts
using it for something internal... we end up in a world of pain in
getting IS-IS running on GRE tunnels. Hence the "WARNING".

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> ...

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.

The NXP NETC switch tag is a proprietary header added to frames after the
source MAC address. The switch tag has 3 types, and each type has 1 ~ 4
subtypes, the details are as follows.
Forward NXP switch tag (Type=0): Represents forwarded frames.
- SubType = 0 - Normal frame processing.
To_Port NXP switch tag (Type=1): Represents frames that are to be sent
to a specific switch port.
- SubType = 0. No request to perform timestamping.
- SubType = 1. Request to perform one-step timestamping.
- SubType = 2. Request to perform two-step timestamping.
- SubType = 3. Request to perform both one-step timestamping and
two-step timestamping.
To_Host NXP switch tag (Type=2): Represents frames redirected or copied
to the switch management port.
- SubType = 0. Received frames redirected or copied to the switch
management port.
- SubType = 1. Received frames redirected or copied to the switch
management port with captured timestamp at the switch port where
the frame was received.
- SubType = 2. Transmit timestamp response (two-step timestamping).
In addition, the length of different type switch tag is different, the
minimum length is 6 bytes, the maximum length is 14 bytes. Currently,
Forward tag, SubType 0 of To_Port tag and Subtype 0 of To_Host tag are
supported. More tags will be supported in the future.

to be permitted.

advertised via NL80211_PMSR_FTM_CAPA_ATTR_TYPE_CAPS. Reject PD
requests if the device does not advertise PD support.
Reject PD requests that set trigger-based ranging, as TB ranging is
not compatible with peer-to-peer proximity detection.
Add ftms_per_burst limit of 4 for PD NTB ranging requests.

Introduce Proximity Detection (PD) capabilities in Peer Measurement
Service (PMSR) as defined in the Wi-Fi Alliance specification
"Proximity Ranging (PR) Implementation Consideration Draft 1.9 Rev 1
section 3.3". This enables devices to advertise peer to peer ranging
support.
Restructure FTM capabilities in cfg80211_pmsr_capabilities to replace
the single support_rsta flag with nested ista and rsta sub-structs,
each carrying per-mode flags for Non-Trigger Based (NTB), Trigger Based
(TB), and EDCA based ranging. This allows drivers to advertise detailed
role and protocol support for both initiator and responder roles.
Add support to pass additional ISTA and RSTA role capabilities to
userspace using new nested ISTA_CAPS and RSTA_CAPS attributes. The
legacy RSTA_SUPPORT flag is retained for backward compatibility.
Add NL80211_PMSR_FTM_CAPA_ATTR_TYPE_CAPS nested attribute using the
nl80211_peer_measurement_ftm_type_capa enum with two sub-flags:
NL80211_PMSR_FTM_TYPE_CAPA_ATTR_INFRA_SUPPORT for STA-to-AP or
AP-to-STA ranging, and NL80211_PMSR_FTM_TYPE_CAPA_ATTR_PD_SUPPORT
for peer-to-peer ranging.
Add CONCURRENT_ISTA_RSTA_SUPPORT as a FTM capability flag indicating
the device can simultaneously act as initiator and responder in a
multi-peer measurement request.
Extend FTM capabilities with antenna configuration fields
(max_no_of_tx_antennas, max_no_of_rx_antennas) for the PR Element
during PASN negotiation, and ranging interval limits
(min_allowed_ranging_interval_edca, min_allowed_ranging_interval_ntb)
to advertise device timing constraints for EDCA and NTB-based ranging.
Update the FTM request validation path in pmsr.c to check RSTA
requests against the per-mode rsta capabilities (NTB, TB, EDCA),
rejecting requests for modes the device does not support.

Currently, the proximity detection (PD) interface type has no
start/stop commands defined, preventing user space from
controlling PD operations through the nl80211 interface.
Add NL80211_CMD_START_PD and NL80211_CMD_STOP_PD commands to
allow user space to start and stop a PD interface. Add the
corresponding start_pd and stop_pd operations to cfg80211_ops
and ieee80211_ops, along with nl80211 command handlers, rdev
wrappers, and tracing support. Validate that drivers advertising
PD interface support implement the required operations. Handle
PD interface teardown during device unregistration and when
the interface leaves the network.

Add a new wdev-only interface type NL80211_IFTYPE_PD to support
Proximity Detection (PD) operations such as PASN and peer measurement
operations. This interface type operates without a netdev, similar to
P2P_DEVICE and NAN interfaces.
Implement support across cfg80211 and mac80211 layers with PD-specific
checks gated by the NL80211_EXT_FEATURE_SECURE_RTT feature flag,
management frame registration and transmission capabilities, and proper
channel context handling where PD interfaces are excluded from bandwidth
calculations. Update mac80211 to recognize the new interface type in the
relevant paths for this management-only interface.
PD discovery can be performed on any available interface, such as
NL80211_IFTYPE_STATION.
If PD/PMSR uses the MAC address of an existing interface type, such as
NL80211_IFTYPE_STATION, then pairing and measurement shall use that
same interface. If PD/PMSR uses a different MAC address, such as a
random MAC address, then pairing and measurement can be performed on a
new NL80211_IFTYPE_PD interface created with that random MAC address.

Currently the remain_on_channel operation does not support
filtering incoming frames by destination MAC address. This
prevents use cases such as PASN authentication in the
responder side that need to receive frames addressed to a
specific MAC during the off-channel period.
Add an rx_addr parameter to the remain_on_channel operation
callback and propagate it through the call chain from nl80211
to driver implementations. Introduce the extended feature
NL80211_EXT_FEATURE_ROC_ADDR_FILTER as a capability gate so
that cfg80211 rejects the request if the driver does not
advertise support for address filtering. Extract the address
from the NL80211_ATTR_MAC attribute when provided in the
netlink message and update the tracing infrastructure to
include the address in remain_on_channel trace events. The
rx_addr parameter is optional and can be NULL, maintaining
backward compatibility with existing drivers.

In SME-in-driver mode, the driver handles the entire (re)association
exchange. Userspace (e.g., wpa_supplicant) currently has no explicit
indication of whether the (re)association exchange was encrypted,
making it difficult to distinguish EPP (Enhanced Privacy Protection,
IEEE 802.11bi) associations from non-EPP associations.
When (Re)Association frame encryption is used, the (Re)Association
Response frame must contain a Key Delivery element as specified in
IEEE P802.11bi/D4.0, Table 9-65. Userspace must process this element
only when the (Re)Association Response frame is actually encrypted.
Processing it unconditionally for unencrypted frames leads to incorrect
behavior. Without an explicit indication from the driver, userspace
cannot determine whether encryption was used and whether the Key
Delivery element is valid.
Add a new flag attribute NL80211_ATTR_ASSOC_ENCRYPTED and a
corresponding field "assoc_encrypted" in cfg80211_connect_resp_params
to indicate that both the (Re)Association Request and Response frames
are transmitted encrypted over the air.
For mac80211-based drivers, extend cfg80211_rx_assoc_resp_data with
the assoc_encrypted field as well, which is then propagated to
cfg80211_connect_resp_params.
Pass the flag to userspace via NL80211_CMD_CONNECT event.

Add pin-operstate enum and operstate_on_dpll_get callback to report
the actual hardware status of a pin with respect to its parent DPLL
device. Unlike pin-state (which reflects administrative intent set
by the user), operstate reflects what the hardware is actually doing.
Defined operational states:
- active: pin is qualified and actively used by the DPLL
- standby: pin is qualified but not actively used by the DPLL
- no-signal: pin does not have a valid signal
- qual-failed: pin signal failed qualification
The operstate is reported inside the pin-parent-device nested
attribute alongside the existing state and phase-offset attributes.

Incrementally consumed buffer rings are generally fully consumed, but
it's quite possible that the application has a minimum size it needs to
meet to avoid truncation. Currently that minimum limit is 1 byte, but
this should be a setting that is the hands of the application. For
recvmsg multishot, a prime use case for incrementally consumed buffers,
the application may get spurious -EFAULT returned at the end of an
incrementally consumed buffer, as less space is available than the
headers need.
Grab a u32 field in struct io_uring_buf_reg, which the application can
use to inform the kernel of the minimum size that should be available
in an incrementally consumed buffer. If less than that is available,
the current buffer is fully processed and the next one will be picked.

Pull networking deletions from Jakub Kicinski:
"Delete some obsolete networking code
Old code like amateur radio and NFC have long been a burden to core
networking developers. syzbot loves to find bugs in BKL-era code, and
noobs try to fix them.
If we want to have a fighting chance of surviving the LLM-pocalypse
this code needs to find a dedicated owner or get deleted. We've talked
about these deletions multiple times in the past and every time
someone wanted the code to stay. It is never very clear to me how many
of those people actually use the code vs are just nostalgic to see it
go. Amateur radio did have occasional users (or so I think) but most
users switched to user space implementations since its all super slow
stuff. Nobody stepped up to maintain the kernel code.
We were lucky enough to find someone who wants to help with NFC so
we're giving that a chance. Let's try to put the rest of this code
behind us"

This set of protocols has long been a huge bug/syzbot magnet,

of the AI-generated bug reports we need to move it out of tree
to protect our sanity.
The code is moved to an out-of-tree repo:

Minimal stub headers are kept for include/net/ax25.h (AX25_P_IP,
AX25_ADDR_LEN, ax25_address) and include/net/rose.h (ROSE_ADDR_LEN)

Remove the ISDN (mISDN, CAPI) subsystem and Bluetooth CMTP protocol
from the kernel tree.
ISDN is a pretty old technology and it's unclear whether anyone still
uses it. I went over the last few years of git history and all the
commits are either tree-wide conversions or syzbot/static analyzer
fixes.
When we discussed removal in the past IIRC there were some concerns
about ISDN still being used in parts of Germany. Unfortunately, the
code base is quite old, none of the current maintainers are familiar
with it and AI tools will have a field day finding bugs here.
Delete this code and preserve it in an out-of-tree repository
for any remaining users:

b2273be8d2 ("caif_virtio: Use vringh_notify_enable correctly")
0d2e1a2926 ("caif_virtio: Introduce caif over virtio")
Not-so-coincidentally, according to "the Internet" ST-Ericsson officially
shut down its modem joint venture in Aug 2013.
If anyone is using this code please yell!
In the 13 years since, the code has accumulated 200 non-merge commits,
of which 71 were cross-tree API changes, 21 carried Fixes: tags, and
the remaining ~110 were cleanups, doc conversions, treewide refactors,
and one partial removal (caif_hsi, ca75bcf0a8).
We are still getting fixes to this code, in the last 10 days there were
3 reports on security@ about CAIF that I have been CCed on.
UAPI constants (AF_CAIF, ARPHRD_CAIF, N_CAIF, VIRTIO_ID_CAIF) and the
SELinux classmap entry are intentionally kept for ABI stability.

Pull nfsd updates from Chuck Lever:
- filehandle signing to defend against filehandle-guessing attacks
(Benjamin Coddington)
The server now appends a SipHash-2-4 MAC to each filehandle when
the new "sign_fh" export option is enabled. NFSD then verifies
filehandles received from clients against the expected MAC;
mismatches return NFS error STALE
- convert the entire NLMv4 server-side XDR layer from hand-written C to
xdrgen-generated code, spanning roughly thirty patches (Chuck Lever)
XDR functions are generally boilerplate code and are easy to get
wrong. The goals of this conversion are improved memory safety, lower
maintenance burden, and groundwork for eventual Rust code generation
for these functions.
- improve pNFS block/SCSI layout robustness with two related changes
(Dai Ngo)
SCSI persistent reservation fencing is now tracked per client and
per device via an xarray, to avoid both redundant preempt operations
on devices already fenced and a potential NFSD deadlock when all nfsd
threads are waiting for a layout return.

Pull tty/serial updates from Greg KH:
"Here is the set of tty and serial driver changes for 7.1-rc1.
Not much here this cycle, biggest thing is the removal of an old
driver that never got any actual hardware support (esp32), and the
second try to moving the tty ports to their own workqueues (first try
was in 7.0-rc1 but was reverted due to problems)
Otherwise it's just a small set of driver updates and some vt modifier
key enhancements.
All have been in linux-next for a while with no reported issues"
