Currently the mptcp code has assumes that disconnect() can fail only
at mptcp_sendmsg_fastopen() time - to avoid a deadlock scenario - and
don't even bother returning an error code.
Soon mptcp_disconnect() will handle more error conditions: let's track
them explicitly.
As a bonus, explicitly annotate TCP-level disconnect as not failing:
the mptcp code never blocks for event on the subflows.

Add metric value validation test to check if metric values are with in
correct value ranges. There are three types of tests included: 1)
positive-value test checks if all the metrics collected are non-negative;
2) single-value test checks if the list of metrics have values in given
value ranges; 3) relationship test checks if multiple metrics follow a
given relationship, e.g. memory_bandwidth_read + memory_bandwidth_write =
memory_bandwidth_total.

When calling bpf_sk_lookup_tcp(), bpf_sk_lookup_udp() or
bpf_skc_lookup_tcp() from tc/xdp ingress, VRF socket bindings aren't
respoected, i.e. unbound sockets are returned, and bound sockets aren't
found.
VRF binding is determined by the sdif argument to sk_lookup(), however
when called from tc the IP SKB control block isn't initialized and thus
inet{,6}_sdif() always returns 0.
Fix by calculating sdif for the tc/xdp flows by observing the device's
l3 enslaved state.
The cg/sk_skb hooking points which are expected to support
inet{,6}_sdif() pass sdif=-1 which makes __bpf_skc_lookup() use the
existing logic.

bpf_tc_sk_lookup_tcp() / bpf_tc_sk_lookup_udp() / bpf_tc_skc_lookup_tcp()

====================
leds: trigger: netdev: add additional modes
This is a continue of [1]. It was decided to take a more gradual
approach to implement LEDs support for switch and phy starting with
basic support and then implementing the hw control part when we have all
the prereq done.
This should be the final part for the netdev trigger.
I added net-next tag and added netdev mailing list since I was informed
that this should be merged with netdev branch.
We collect some info around and we found a good set of modes that are
common in almost all the PHY and Switch.
These modes are:
- Modes for dedicated link speed(10, 100, 1000 mbps). Additional mode
can be added later following this example.
- Modes for half and full duplex.
The original idea was to add hw control only modes.
While the concept makes sense in practice it would results in lots of
additional code and extra check to make sure we are setting correct modes.
With the suggestion from Andrew it was pointed out that using the ethtool
APIs we can actually get the current link speed and duplex and this
effectively removed the problem of having hw control only modes since we
can fallback to software.
Since these modes are supported by software, we can skip providing an
user for this in the LED driver to support hw control for these new modes
(that will come right after this is merged) and prevent this to be another
multi subsystem series.
For link speed and duplex we use ethtool APIs.
To call ethtool APIs, rtnl lock is needed but this can be skipped on
handling netdev events as the lock is already held.

Add additional modes for specific link duplex. Use ethtool APIs to get the
current link duplex and enable the LED accordingly. Under netdev event
handler the rtnl lock is already held and is not needed to be set to
access ethtool APIs.
This is especially useful for PHY and Switch that supports LEDs hw
control for specific link duplex.
Add additional modes:
- half_duplex: Turn on LED when link is half duplex
- full_duplex: Turn on LED when link is full duplex

connected one green and one orange where the green is turned on with
1000mbps speed and orange is turned on with 10mpbs speed)
On mode set from sysfs we check if we have enabled split link speed mode
and reject enabling generic link mode to prevent wrong and redundant
configuration.
Rework logic on the set baseline state to support these new modes to
select if we need to turn on or off the LED.
Add additional modes:
- link_10: Turn on LED when link speed is 10mbps
- link_100: Turn on LED when link speed is 100mbps
- link_1000: Turn on LED when link speed is 1000mbps

'selftests-preparations-for-out-of-order-operations-patches-in-mlxsw'
Petr Machata says:
====================
selftests: Preparations for out-of-order-operations patches in mlxsw
The mlxsw driver currently makes the assumption that the user applies
configuration in a bottom-up manner. Thus netdevices need to be added to
the bridge before IP addresses are configured on that bridge or SVI added
on top of it. Enslaving a netdevice to another netdevice that already has
uppers is in fact forbidden by mlxsw for this reason. Despite this safety,
it is rather easy to get into situations where the offloaded configuration
is just plain wrong.
Over the course of the following several patchsets, mlxsw code is going to
be adjusted to diminish the space of wrongly offloaded configurations.
Ideally the offload state will reflect the actual state, regardless of the
sequence of operation used to construct that state.
Several selftests build configurations that will not be offloadable in the
future on some systems. The reason is that what will get offloaded is the
actual configuration, not the configuration steps.
For example, when a port is added to a bridge that has an IP address, that
bridge will get a RIF, which it would not have with the current code. But
on Nvidia Spectrum-1 machines, MAC addresses of all RIFs need to have the
same prefix, which the bridge will violate. The RIF thus couldn't be
created, and the enslavement is therefore canceled, because it would lead
to an unoffloadable configuration. This breaks some selftests.
In this patchset, adjust selftests to avoid the configurations that mlxsw
would be incapable of offloading, while maintaining relevance with regards
to the feature that is being tested. There are generally two cases of
fixes:
- Disabling IPv6 autogen on bridges that do not participate in routing,
either because of the abovementioned requirement to keep the same MAC
prefix on all in-HW router interfaces, or, on 802.1ad bridges, because
in-HW router interfaces are not supported at all.
- Setting the bridge MAC address to what it will become after the first
member port is attached, so that the in-HW router interface is created
with a supported MAC address.
The patchset is then split thus:
- Patches #1-#7 adjust generic selftests
- Patches #8-#16 adjust mlxsw-specific selftests

In a future patch, mlxsw will start adding RIFs to uppers of front panel
port netdevices, if they have an IP address.
At the time that the front panel port is enslaved to the bridge, the bridge
MAC address does not have the same prefix as other interfaces in the
system. On Nvidia Spectrum-1 machines all the RIFs have to have the same
38-bit MAC address prefix. Since the bridge does not obey this limitation,
the RIF cannot be created, and the enslavement attempt is vetoed on the
grounds of the configuration not being offloadable.
The bridge eventually inherits MAC address from its first member, after the
enslavement is acked. A number of (mainly VXLAN) selftests already work
around the problem by setting the MAC address to whatever it will
eventually be anyway. Do the same for this selftest.

The swp enslavement to the 802.1ad bridge is not allowed, because RIFs are
not allowed to be created for 802.1ad bridges, but the address indicates
one needs to be created. Thus the veto selftests fail already during the
port enslavement. Then the attempt to create a VLAN on top of the same
bridge is not vetoed, because the bridge is not related to mlxsw, and the
selftest fails.
Fix by disabling automatic IPv6 address generation for the bridges in this
selftest, thus exempting them from the mlxsw router attention.

In a future patch, mlxsw will start adding RIFs to uppers of front panel
port netdevices, if they have an IP address.
At the time that the front panel port is enslaved to the bridge, the bridge
MAC address does not have the same prefix as other interfaces in the
system. On Nvidia Spectrum-1 machines all the RIFs have to have the same
38-bit MAC address prefix. Since the bridge does not obey this limitation,
the RIF cannot be created, and the enslavement attempt is vetoed on the
grounds of the configuration not being offloadable.
The bridge eventually inherits MAC address from its first member, after the
enslavement is acked. A number of (mainly VXLAN) selftests already work
around the problem by setting the MAC address to whatever it will
eventually be anyway. Do the same here.

Hello,
This patch is to expose misc.current on cgroup v2 root for tracking
how much of the resource has been consumed in total on the system.
Most of the cloud infrastucture use cgroup to fetch the host
information for scheduling purpose.
Currently, the misc controller can be used by Intel TDX HKIDs and
AMD SEV ASIDs, which are both used for creating encrypted VMs.
Intel TDX and AMD SEV are mostly be used by the cloud providers
for providing confidential VMs.
In actual use of a server, these confidential VMs may be launched
in different ways. For the cloud solution, there are kubvirt and
coco (tracked by kubepods.slice); on host, they can be booted
directly through qemu by end user (tracked by user.slice), etc.
In this complex environment, when wanting to know how many resource
is used in total it has to iterate through all existing slices to
get the value of each misc.current and add them up to calculate
the total number of consumed keys.
So exposing misc.current to root cgroup tends to give much easier
when calculates how much resource has been used in total, which
helps to schedule and count resources for the cloud infrastucture.

Qualcomm driver updates for v6.5
Konrad Dybcio is promoted, from reviewer, to co-maintainer.
The mdt_loader gets a fix to the detection of split binaries, where the
previous logic sometimes concluded that the first segments was not
split, in a split image. The unconditional calling of
scm_pas_mem_setup() turns out to cause a regression and is reverted.
The altmode subfunction of pmic_glink is enabled for SM8450.
A new driver for exposing power statistics from the RPM, for debugging
purposes, is introduced.
OCMEM gets a debug prints of the hardware version, QMI helpers are
transitioned to alloc_ordered_workqueue() and an error message in
ramp_controller is improved.
An API is introduced to the SMEM driver to allow other drivers to query
the SoC id, rather than open-coding the parsing of the relevant SMEM
item. This is then used to clean up the Qualcomm NVMEM-based cpufreq
driver.
Socinfo is extended with knowledge about IPQ5018, IPQ5312 and IPQ5302.
