It appears nothing needs it. The kernel builds fine with this
include removed, building an otherwise empty source file with:
#include <linux/skbuff.h>
#ifdef _LINUX_NET_H
#error linux/net.h is back
#endif
works too (meaning net.h is not just pulled in indirectly).
This gives us a slight 0.5% reduction in the pre-processed size
of skbuff.h.

ifcvf_mgmt_dev leaks memory if it is not freed before

"""
Since "vhost/scsi: fix reuse of &vq->iov[out] in response"
we have this:
cmd->tvc_resp_iov = vq->iov[vc.out];
cmd->tvc_in_iovs = vc.in;
combined with
iov_iter_init(&iov_iter, ITER_DEST, &cmd->tvc_resp_iov,
cmd->tvc_in_iovs, sizeof(v_rsp));
in vhost_scsi_complete_cmd_work(). We used to have ->tvc_resp_iov
_pointing_ to vq->iov[vc.out]; back then iov_iter_init() asked to
set an iovec-backed iov_iter over the tail of vq->iov[], with
length being the amount of iovecs in the tail.
Now we have a copy of one element of that array. Fortunately, the members
following it in the containing structure are two non-NULL kernel pointers,
so copy_to_iter() will not copy anything beyond the first iovec - kernel
pointer is not (on the majority of architectures) going to be accepted by
access_ok() in copyout() and it won't be skipped since the "length" (in
reality - another non-NULL kernel pointer) won't be zero.
So it's not going to give a guest-to-qemu escalation, but it's definitely
a bug. Frankly, my preference would be to verify that the very first iovec
is long enough to hold rsp_size. Due to the above, any users that try to
give us vq->iov[vc.out].iov_len < sizeof(struct virtio_scsi_cmd_resp)
would currently get a failure in vhost_scsi_complete_cmd_work()
anyway.
"""
However, the spec doesn't say anything about the legacy descriptor
layout for the respone. So this patch tries to not assume the response
to reside in a single separate descriptor which is what commit
79c14141a487 ("vhost/scsi: Convert completion path to use") tries to
achieve towards to ANY_LAYOUT.
This is done by allocating and using dedicate resp iov in the
command. To be safety, start with UIO_MAXIOV to be consistent with the
limitation that we advertise to the vhost_get_vq_desc().
Testing with the hacked virtio-scsi driver that use 1 descriptor for 1
byte in the response.

When the vhost iotlb is used along with a guest virtual iommu
and the guest gets rebooted, some MISS messages may have been
recorded just before the reboot and spuriously executed by
the virtual iommu after the reboot.
As vhost does not have any explicit reset user API,
VHOST_NET_SET_BACKEND looks a reasonable point where to clear
the pending messages, in case the backend is removed.
Export vhost_clear_msg() and call it in vhost_net_set_backend()
when fd == -1.

====================
net: ipa: abstract status parsing
Under some circumstances, IPA generates a "packet status" structure
that describes information about a packet. This is used, for
example, when offload hardware detects an error in a packet, or
otherwise discovers a packet needs special handling. In this case,
the status is delivered (along with the packet it describes) to a
"default" endpoint so that it can be handled by the AP.
Until now, the structure of this status information hasn't changed.
However, to support more than 32 endpoints, this structure required
some changes, such that some fields are rearranged in ways that are
tricky to represent using C code.
This series updates code related to the IPA status structure. The
first patch uses a local variable to avoid recomputing a packet
length more than once. The second stops using sizeof() to determine
the size of an IPA packet status structure. Patches 3-5 extend the
definitions for values held in packet status fields. Patch 6 does a
little general cleanup to make patch 7 simpler. Patch 7 stops using
a C structure to represent packet status; instead, a new function
fetches values "by name" from a buffer containing such a structure.
The last patch updates this function so it also supports IPA v5.0+.

Stop assuming the IPA packet status has a fixed format (defined by
a C structure). Instead, use a function to extract each field from
a block of data interpreted as an IPA packet status. Define an
enumerated type that identifies the fields that can be extracted.
The current function extracts fields based on the existing
ipa_status structure format (which is no longer used).
Define IPA_STATUS_RULE_MISS, to replace the calls to field_max() to
represent that condition; those depended on the knowing the width of
a filter or router rule in the IPA packet status structure.

The next patch reworks how the IPA packet status structure is
interpreted. This patch does some preparatory work, to make it
easier to see the effect of that change:
- Change a few functions that access fields in a IPA packet status
structure to store field values in local variables with names
related to the field.
- Pass a void pointer rather than an (equivalent) status pointer
to two functions called by ipa_endpoint_status_parse().
- Use "rule" rather than "val" as the name of a variable that
holds a routing rule ID.
- Consistently use "IPA packet status" rather than "status
element" when referring to this data structure.

We change recently the memalloc helper to use
dma_alloc_noncontiguous() and the fallback to get_pages(). Although
lots of issues with IOMMU (or non-IOMMU) have been addressed, but
there seems still a regression on Xen PV. Interestingly, the only
proper way to work is use dma_alloc_coherent(). The use of
dma_alloc_coherent() for SG buffer was dropped as it's problematic on
IOMMU systems. OTOH, Xen PV has a different way, and it's fine to use
the dma_alloc_coherent().
This patch is a workaround for Xen PV. It consists of the following
changes:
- For Xen PV, use only the fallback allocation without
dma_alloc_noncontiguous()
- In the fallback allocation, use dma_alloc_coherent();
the DMA address from dma_alloc_coherent() is returned in get_addr
ops
- The DMA addresses are stored in an array; the first entry stores the
number of allocated pages in lower bits, which are referred at
releasing pages again

The kernel crash was caused by a BPF program attached to the
"lsm_cgroup/socket_sock_rcv_skb" hook, which performed a call to
`bpf_setsockopt()` in order to set the TCP_NODELAY flag as an
example. Flags like TCP_NODELAY can prompt the kernel to flush a
socket's outgoing queue, and this hook
"lsm_cgroup/socket_sock_rcv_skb" is frequently triggered by
softirqs. The issue was that in certain circumstances, when
`tcp_write_xmit()` was called to flush the queue, it would also allow
BH (bottom-half) to run. This could lead to our program attempting to
flush the same socket recursively, which caused a `skbuff` to be
unlinked twice.
`security_sock_rcv_skb()` is triggered by `tcp_filter()`. This occurs
before the sock ownership is checked in `tcp_v4_rcv()`. Consequently,
if a bpf program runs on `security_sock_rcv_skb()` while under softirq
conditions, it may not possess the lock needed for `bpf_setsockopt()`,
thus presenting an issue.
The patch fixes this issue by ensuring that a BPF program attached to
the "lsm_cgroup/socket_sock_rcv_skb" hook is not allowed to call
`bpf_setsockopt()`.
The differences from v1 are
- changing commit log to explain holding the lock of the sock,
- emphasizing that TCP_NODELAY is not the only flag, and
- adding the fixes tag.

Although most calls of scsi_device_put() happen from non-atomic context,
alua_rtpg_queue() calls this function from atomic context if
alua_rtpg_queue() itself is called from atomic context. alua_rtpg_queue()
is always called from contexts where the caller must hold at least one
reference to the scsi device in question. This means that the reference
taken by alua_rtpg_queue() itself can't be the last one, and thus can be
dropped without entering the code path in which scsi_device_put() might
actually sleep. Hence move the might_sleep() annotation from
scsi_device_put() into scsi_device_dev_release().

I'm not exactly clear on what strange workflow causes people to do it,
but clearly occasionally some files end up being committed as executable
even though they clearly aren't.
This is a reprise of commit 90fda63fa115 ("treewide: fix up files
incorrectly marked executable"), just with a different set of files (but
with the same trivial shell scripting).
So apparently we need to re-do this every five years or so, and Joe
needs to just keep reminding me to do so ;)

While looking through legacy platform data users, I noticed that
the DT probing never uses data from the DT properties, as the
platform_data structure gets overwritten directly after it
is initialized.
There have never been any boards defining the platform_data in
the mainline kernel either, so this driver so far only worked
with patched kernels or with the default values.
For the benefit of possible downstream users, fix the DT probe
by no longer overwriting the data.

The 'ublk_chr_class' is needed when deleting ublk char devices in
ublk_exit(), so move it after devices(idle) are removed.

CONFIG_ETHTOOL_NETLINK=n
ethtool_aggregate_*_stats() are implemented in net/ethtool/stats.c, a
file which is compiled out when CONFIG_ETHTOOL_NETLINK=n. In order to
avoid adding Kbuild dependencies from drivers (which call these helpers)
on CONFIG_ETHTOOL_NETLINK, let's add some shim definitions which simply
make the helpers dead code.
This means the function prototypes should have been located in
include/linux/ethtool_netlink.h rather than include/linux/ethtool.h.

It turns out the optimisation implemented by commit 4f2c3872dde5 is
totally broken, since all the places that consume hw->dtcs_used for
events other than cycle count are still not expecting it to be sparsely
populated, and fail to read all the relevant DTC counters correctly if
so.
If implemented correctly, the optimisation potentially saves up to 3
register reads per event update, which is reasonably significant for
events targeting a single node, but still not worth a massive amount of
additional code complexity overall. Getting it right within the current
design looks a fair bit more involved than it was ever intended to be,
so let's just make a functional revert which restores the old behaviour
while still backporting easily.

Matthieu Baerts says:
====================
mptcp: add mixed v4/v6 support for the in-kernel PM
Before these patches, the in-kernel Path-Manager would not allow, for
the same MPTCP connection, having a mix of subflows in v4 and v6.
MPTCP's RFC 8684 doesn't forbid that and it is even recommended to do so
as the path in v4 and v6 are likely different. Some networks are also
v4 or v6 only, we cannot assume they all have both v4 and v6 support.
Patch 1 then removes this artificial constraint in the in-kernel PM
currently enforcing there are no mixed subflows in place, either in
address announcement or in subflow creation areas.
Patch 2 makes sure the sk_ipv6only attribute is also propagated to
subflows, just in case a new PM wouldn't respect it.
Some selftests have also been added for the in-kernel PM (patch 3).
Patches 4 to 8 are just some cleanups and small improvements in the
printed messages in the userspace PM. It is not linked to the rest but
identified when working on a related patch modifying this selftest,
already in -net:
commit 4656d72c1efa ("selftests: mptcp: userspace: validate v4-v6 subflows mix")
