Merge tag 'spdx-5.2-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull SPDX update from Greg KH:
"Here is a series of patches that add SPDX tags to different kernel
files, based on two different things:

- SPDX entries are added to a bunch of files that we missed a year
ago that do not have any license information at all.

These were either missed because the tool saw the MODULE_LICENSE()
tag, or some EXPORT_SYMBOL tags, and got confused and thought the
file had a real license, or the files have been added since the
last big sweep, or they were Makefile/Kconfig files, which we
didn't touch last time.

- Add GPL-2.0-only or GPL-2.0-or-later tags to files where our scan
tools can determine the license text in the file itself. Where this
happens, the license text is removed, in order to cut down on the
700+ different ways we have in the kernel today, in a quest to get
rid of all of these.

These patches have been out for review on the linux-spdx@vger mailing
list, and while they were created by automatic tools, they were
hand-verified by a bunch of different people, all whom names are on
the patches are reviewers.

The reason for these "large" patches is if we were to continue to
progress at the current rate of change in the kernel, adding license
tags to individual files in different subsystems, we would be finished
in about 10 years at the earliest.

There will be more series of these types of patches coming over the
next few weeks as the tools and reviewers crunch through the more
"odd" variants of how to say "GPLv2" that developers have come up with
over the years, combined with other fun oddities (GPL + a BSD
disclaimer?) that are being unearthed, with the goal for the whole
kernel to be cleaned up.

These diffstats are not small, 3840 files are touched, over 10k lines
removed in just 24 patches"

Merge branch 'packet-sampling-offload'

Jiri Pirko says:

====================
Add support for offloading packet-sampling

Yotam says:

The first patch introduces the psample module, a netlink channel dedicated
to packet sampling implemented using generic netlink. This module provides
a generic way for kernel modules to sample packets, while not being tied
to any specific subsystem like NFLOG.

The second patch adds the sample tc action, which uses psample to randomly
sample packets that match a classifier. The user can configure the psample
group number, the sampling rate and the packet's truncation (to save
kernel-user traffic).

The last two patches add the support for offloading the matchall-sample
tc command in the mlxsw driver, for ingress qdiscs.

An example for psample usage can be found in the libpsample project at:
https://github.com/Mellanox/libpsample

v1->v2:
- Reword first patch's commit message
- Fix typo in comment in second patch
- Change order of tc_sample uapi enum to match convention
- Rename act_sample action callback tcf_sample -> tcf_sample_act

net: Introduce psample, a new genetlink channel for packet sampling

Add a general way for kernel modules to sample packets, without being tied
to any specific subsystem. This netlink channel can be used by tc,
iptables, etc. and allow to standardize packet sampling in the kernel.

For every sampled packet, the psample module adds the following metadata
fields:

PSAMPLE_ATTR_IIFINDEX - the packets input ifindex, if applicable

PSAMPLE_ATTR_OIFINDEX - the packet output ifindex, if applicable

PSAMPLE_ATTR_ORIGSIZE - the packet's original size, in case it has been
truncated during sampling

PSAMPLE_ATTR_SAMPLE_GROUP - the packet's sample group, which is set by the
user who initiated the sampling. This field allows the user to
differentiate between several samplers working simultaneously and
filter packets relevant to him

PSAMPLE_ATTR_GROUP_SEQ - sequence counter of last sent packet. The
sequence is kept for each group

PSAMPLE_ATTR_SAMPLE_RATE - the sampling rate used for sampling the packets

PSAMPLE_ATTR_DATA - the actual packet bits

The sampled packets are sent to the PSAMPLE_NL_MCGRP_SAMPLE multicast
group. In addition, add the GET_GROUPS netlink command which allows the
user to see the current sample groups, their refcount and sequence number.
This command currently supports only netlink dump mode.
