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.

Fixes: 655f8919d5 ("bonding: add min links parameter to 802.3ad")

Pablo Neira Ayuso says:

====================
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.

a4597204b6 dt-bindings: net: airoha: Add GDM port ethernet child node
EN7581 and AN7583 SoCs support connecting multiple external SerDes to GDM3
or GDM4 ports via a hw arbiter that manages the traffic in a TDM manner.
As a result multiple net_devices can connect to the same GDM{3,4} port
and there is a theoretical "1:n" relation between GDM ports and
net_devices.
Introduce the ethernet node child of a specific GDM port in order to model
a given net_device that is connected via the external arbiter to the
GDM{3,4} port. This new ethernet node is defined by the "airoha,eth-port"
compatible string. Please note GDM1 and GDM2 does not support the
connection with the external arbiter and they are represented by an
ethernet node defined by the "airoha,eth-mac" compatible string.

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.

this redirect unnecessary for discoverability.

Two files still reference dsa.txt, forcing readers through an extra

2020. Update references in lan9303.txt and

Commit c36069c6f4 ("dt-bindings: ethernet: eswin: add optional TXD and

As a result, dt-schema implicitly required all 6 cells, which broke
backward compatibility with existing 4-cell device trees.

Add minItems: 4 to preserve backward compatibility.

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

ba3e43a9e6 soc: fixes for 7.1, part 2
Following the previous set of fixes, this addresses another significant
 number of small issues found in firmware drivers (tee, optee, qcomtee,
 qcom ice, exynos acpm) drivers through various tools. This is about
 error handling, resource leaks, concurrency and a use-after-free bug.
 
 The fixes for the Qualcomm ICE driver also introduce interface changes
 in the UFS and MMC drivers using it.
 
 Outside of firmware drivers, there are a few fixes across the tree:
 
  - Minor driver code mistakes in the Atmel EBI memory controller,
    the i.MX soc ID driver and socfpga boot logic
 
  - A defconfig change to avoid a boot time regression on multiple
    qualcomm boards
 
  - Device tree fixes for qualcomm, at91 and gemini, addressing
    mostly minor configuration mistakes

hardware features are similar with jh7100.

Add jhb100 GMAC compatible and reset, interrupts features.
jhb100 dwmac has only one reset signal and one interrupt
line.

jhb100 SGMII interface tx/rx mac clock is split and require to
set clock rate in 10M/100M/1000M speed. So dts need to add a
new rx clock in code, dts and dt binding doc.

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 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.

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".

Update netdev feature documentation for current locking rules and

locking, keep the NETIF_F_NEVER_CHANGE rule with the VLAN challenged
exception, fix the HSR duplication wording, and document netdev->netmem_tx
as a device flag rather than a feature bit.

Split the list of basic feature sets from the "extra" ones like
vlan_features. A bunch of the newer fields weren't documented and
having them all together would be confusing.

 - The simple-driver probe example fell through into err_undo after

 - Clarify the netdev_priv() paragraph: "(netdev_priv())" was easy

   that it refers to extra pointers stored in the device private
   struct.
 - ndo_setup_tc synchronization note: TC_SETUP_BLOCK / TC_SETUP_FT
   actually run under block->cb_lock, not "NFT locks", and rtnl_lock
   may or may not be held depending on path.
 - ->lltx guidance reads as very outdated, it's not really deprecated.

   in the past but I can't think of such a case in the last decade.

6b22d433aa net/handshake: Pass negative errno through handshake_complete()
handshake_complete() declares status as unsigned int and
tls_handshake_done() negates that value (-status) before handing
it to the TLS consumer. Consumers match on negative errno
constants -- xs_tls_handshake_done() has

	switch (status) {
	case 0:
	case -EACCES:
	case -ETIMEDOUT:
		lower_transport->xprt_err = status;
		break;
	default:
		lower_transport->xprt_err = -EACCES;
	}

so the API as designed expects callers to pass positive errno
values that the tlshd shim then negates.

Three internal callers in handshake_nl_accept_doit(), the
net-exit drain, and a kunit test follow kernel convention and
pass negative errnos -- -EIO, -ETIMEDOUT, -ETIMEDOUT. The
implicit conversion to unsigned int turns -ETIMEDOUT into
0xFFFFFF92; the subsequent -status in tls_handshake_done()
wraps back to 110, the consumer's switch falls through, and
the xprt reports -EACCES on what should be -ETIMEDOUT or -EIO.

Fix the API rather than the call sites. The natural kernel
convention is negative errno in, negative errno out. Change
handshake_complete() and hp_done to take int status, drop the
negation in tls_handshake_done(), and negate once in
handshake_nl_done_doit() where status arrives from the wire
as an unsigned netlink attribute. The three internal callers
were already correct under that convention and need no change.

At the same wire boundary, declare MAX_ERRNO as the netlink
policy upper bound for HANDSHAKE_A_DONE_STATUS. Attribute
validation rejects out-of-range values before
handshake_nl_done_doit() runs, and negating a bounded u32 there
stays within int range -- closing the UBSAN-visible signed-
integer overflow that an unconstrained u32 would invoke.

Add YAML netlink spec for the OVS_PACKET_FAMILY (ovs_packet).
This completes the set of OVS genetlink family specs (ovs_datapath,
ovs_flow, ovs_vport already exist).

The spec defines three operations: MISS (event), ACTION (event),
and EXECUTE (do). MISS and ACTION are kernel-to-userspace upcalls
sent via genlmsg_unicast(); EXECUTE is the only registered genl
operation.

Key, actions, and egress-tun-key attributes are typed as binary
rather than nest because the nested attribute definitions belong
to the ovs_flow spec and cross-spec references are not supported
by the YNL framework.

80501dff81 Documentation/arch/x86: Hide clearcpuid=
This option was never meant to be used in production because it solely
clears the X86_FEATURE kernel-internal representation of what CPUID bits
it has detected and doesn't do any *proper* feature disablement like
clearing CR4.CET in the user shadow stack case, for example.

So remove its documentation so that it doesn't get used in production
and people get silly ideas. It is meant strictly for debugging; and if
a chicken bit for properly disabling a feature is warranted, then that
would need proper enablement.

No functional changes.

c22407252a sound fixes for 7.1-rc5
As expected, we still continue receiving lots of small fixes.
 One major change is about HD-audio pending IRQ handling, but this
 would influence only on odd machines or slow VMs.  There are a few
 other fixes for the core part, but most of them are not-too-serious
 UAF fixes, while the rest are mostly device-specific fixes and quirks.
 
 ALSA Core:
 - Fix for PCM silencing with bogus iov_iter
 - Fixes for past-the-end iterators in timer and seq
 - Serialization of UMP output teardown
 - Rate-limit ELD parsing errors
 
 HD-audio:
 - Fixes for IRQ work handling and SSID matching
 - Various Realtek quirks for HP and ASUS laptops, including LED fixes
 
 ASoC:
 - Intel: ACPI match table updates for PTL, NVL, and ARL platforms
 - Cirrus Logic: Fixes for cs-amp-lib and cs35l56 codecs
 - Various platform fixes for AMD, FSL SAI, TI OMAP, and Qualcomm
 - DT-binding fix for MediaTek
 
 Others:
 - USB ua101: Reject too-short USB descriptors
 - Scarlett2: Fix for flash writes
 - ASIHPI: Fix for potential OOB access
 - AMD SPI: Fix for bus number in ACPI probe
