f8d7a3d211 power: supply: Add driver for pm8916 lbc
pm8916 LBC is a Linear Battery Charger hardware block in pm8916 PMIC.

This block implements simple CC/CV charging for Li-Po batteries.
The hardware has internal state machine to switch between modes and
works mostly autonomously, only needing the limits and targets to be
set to operate.

This driver allows setting limits and enabling the LBC block, monitoring
it's state.

098bce1838 power: supply: Add pm8916 VM-BMS support
This driver adds basic support for VM-BMS found in pm8916.

VM-BMS is a very basic fuel-gauge hardware block that is, sadly,
incapable of any gauging. The hardware supports measuring OCV in
sleep mode, where the battery is not in use, or measuring average
voltage over time when the device is active.

This driver implements basic value readout from this block.

58e4aacb74 power: supply: Propagate of_node to child device
Ensure that the dynamically created power supply device sets its
->of_node if the driver supplies one.  This brings it in line with
several other subsystems (see git grep 'of_node =.*parent.*of_node') and
allows easier identification of the device from udev rules and similar.

Before this patch:

 ls: cannot access 'bq256xx-battery/of_node': No such file or directory
 # ls -l bq256xx-battery/hwmon1/of_node

a9ce385344 dm: don't attempt to queue IO under RCU protection
dm looks up the table for IO based on the request type, with an
assumption that if the request is marked REQ_NOWAIT, it's fine to
attempt to submit that IO while under RCU read lock protection. This
is not OK, as REQ_NOWAIT just means that we should not be sleeping
waiting on other IO, it does not mean that we can't potentially
schedule.

A simple test case demonstrates this quite nicely:

int main(int argc, char *argv[])
{
        struct iovec iov;
        int fd;

        fd = open("/dev/dm-0", O_RDONLY | O_DIRECT);
        posix_memalign(&iov.iov_base, 4096, 4096);
        iov.iov_len = 4096;
        preadv2(fd, &iov, 1, 0, RWF_NOWAIT);
        return 0;
}

which will instantly spew:

where in fact it is dm itself that attempts to allocate a bio clone with
GFP_NOIO under the rcu read lock, regardless of the request type.

Fix this by getting rid of the special casing for REQ_NOWAIT, and just
use the normal SRCU protected table lookup. Get rid of the bio based
table locking helpers at the same time, as they are now unused.

Pull selinux fix from Paul Moore:
 "A relatively small SELinux patch to fix an issue with a
  vfs/LSM/SELinux patch that went upstream during the recent merge
  window.

  The short version is that the original patch changed how we
  initialized mount options to resolve a NFS issue and we inadvertently
  broke a use case due to the changed behavior.

  The fix restores this behavior for the cases that require it while
  keeping the original NFS fix in place"

Add a driver for the Mitsumi MM8013 fuel gauge. The driver is a vastly
cleaned up and improved version of the one that shipped in some obscure

c0bb9fb0e5 bpf: Fix BTF_ID symbol generation collision in tools/
Marcus and Satya reported an issue where BTF_ID macro generates same
symbol in separate objects and that breaks final vmlinux link.

  ld.lld: error: ld-temp.o <inline asm>:14577:1: symbol
  '__BTF_ID__struct__cgroup__624' is already defined

This can be triggered under specific configs when __COUNTER__ happens to
be the same for the same symbol in two different translation units,
which is already quite unlikely to happen.

Add __LINE__ number suffix to make BTF_ID symbol more unique, which is
not a complete fix, but it would help for now and meanwhile we can work

There is no fundamental reason, why multi-buffer XDP and XDP kfunc RX hints
cannot coexist in a single program.

Allow those features to be used together by modifying the flags condition
for dev-bound-only programs, segments are still prohibited for fully
offloaded programs, hence additional check.

====================
Extend netdev netlink family to expose the bitmask with the
kfuncs that the device implements. The source of truth is the
device's xdp_metadata_ops. There is some amount of auto-generated
netlink boilerplate; the change itself is super minimal.

fc45c5b642 bpf: make it easier to add new metadata kfunc
No functional changes.

Instead of having hand-crafted code in bpf_dev_bound_resolve_kfunc,
move kfunc <> xmo handler relationship into XDP_METADATA_KFUNC_xxx.
This way, any time new kfunc is added, we don't have to touch
bpf_dev_bound_resolve_kfunc.

Also document XDP_METADATA_KFUNC_xxx arguments since we now have
more than two and it might be confusing what is what.

d609f3d228 xsk: add multi-buffer support for sockets sharing umem
Userspace applications indicate their multi-buffer capability to xsk
using XSK_USE_SG socket bind flag. For sockets using shared umem the
bind flag may contain XSK_USE_SG only for the first socket. For any
subsequent socket the only option supported is XDP_SHARED_UMEM.

Add option XDP_UMEM_SG_FLAG in umem config flags to store the
multi-buffer handling capability when indicated by XSK_USE_SG option in
bing flag by the first socket. Use this to derive multi-buffer capability
for subsequent sockets in xsk core.

A suitable replacement is `strscpy_pad` due to the fact that it

maintaining the NUL-padding behavior that `strncpy` provides. I am not
sure whether NUL-padding is strictly needed but I see in

the same functionality.

837723b22a netfilter, bpf: Adjust timeouts of non-confirmed CTs in bpf_ct_insert_entry()
bpf_nf testcase fails on s390x: bpf_skb_ct_lookup() cannot find the entry
that was added by bpf_ct_insert_entry() within the same BPF function.

The reason is that this entry is deleted by nf_ct_gc_expired().

The CT timeout starts ticking after the CT confirmation; therefore
nf_conn.timeout is initially set to the timeout value, and
__nf_conntrack_confirm() sets it to the deadline value.

bpf_ct_insert_entry() sets IPS_CONFIRMED_BIT, but does not adjust the
timeout, making its value meaningless and causing false positives.

Fix the problem by making bpf_ct_insert_entry() adjust the timeout,
like __nf_conntrack_confirm().

d0d362ffa3 i40e: Fix VF VLAN offloading when port VLAN is configured
If port VLAN is configured on a VF then any other VLANs on top of this VF
are broken.

During i40e_ndo_set_vf_port_vlan() call the i40e driver reset the VF and
iavf driver asks PF (using VIRTCHNL_OP_GET_VF_RESOURCES) for VF capabilities
but this reset occurs too early, prior setting of vf->info.pvid field
and because this field can be zero during i40e_vc_get_vf_resources_msg()
then VIRTCHNL_VF_OFFLOAD_VLAN capability is reported to iavf driver.

This is wrong because iavf driver should not report VLAN offloading
capability when port VLAN is configured as i40e does not support QinQ
offloading.

Fix the issue by moving VF reset after setting of vf->port_vlan_id
field.

Without this patch:
$ echo 1 > /sys/class/net/enp2s0f0/device/sriov_numvfs
$ ip link set enp2s0f0 vf 0 vlan 3
$ ip link set enp2s0f0v0 up
$ ip link add link enp2s0f0v0 name vlan4 type vlan id 4
$ ip link set vlan4 up
...
$ ethtool -k enp2s0f0v0 | grep vlan-offload
rx-vlan-offload: on
tx-vlan-offload: on
$ dmesg -l err | grep iavf
[1292500.742914] iavf 0000:02:02.0: Failed to add VLAN filter, error IAVF_ERR_INVALID_QP_ID

With this patch:
$ echo 1 > /sys/class/net/enp2s0f0/device/sriov_numvfs
$ ip link set enp2s0f0 vf 0 vlan 3
$ ip link set enp2s0f0v0 up

5f3d319a24 iavf: schedule a request immediately after add/delete vlan
When the iavf driver wants to reconfigure the VLAN filters
(iavf_add_vlan, iavf_del_vlan), it sets a flag in
aq_required:
  adapter->aq_required |= IAVF_FLAG_AQ_ADD_VLAN_FILTER;
or:
  adapter->aq_required |= IAVF_FLAG_AQ_DEL_VLAN_FILTER;

This is later processed by the watchdog_task, but it runs periodically
every 2 seconds, so it can be a long time before it processes the request.

In the worst case, the interface is unable to receive traffic for more
than 2 seconds for no objective reason.

c8de44b577 iavf: do not process adminq tasks when __IAVF_IN_REMOVE_TASK is set
Prevent schedule operations for adminq during device remove and when
__IAVF_IN_REMOVE_TASK flag is set. Currently, the iavf_down function
adds operations for adminq that shouldn't be processed when the device
is in the __IAVF_REMOVE state.

Reproduction:

echo 4 > /sys/bus/pci/devices/0000:17:00.0/sriov_numvfs
ip link set dev ens1f0 vf 0 trust on
ip link set dev ens1f0 vf 1 trust on

Current result:

Expected result:
When passthrough NIC VF to guest, the VF in guest should always get
the same mac as it in host.
