"Another round of SPDX updates for 5.2-rc6

Here is what I am guessing is going to be the last "big" SPDX update
for 5.2. It contains all of the remaining GPLv2 and GPLv2+ updates
that were "easy" to determine by pattern matching. The ones after this
are going to be a bit more difficult and the people on the spdx list
will be discussing them on a case-by-case basis now.

Another 5000+ files are fixed up, so our overall totals are:
Files checked: 64545
Files with SPDX: 45529

Compared to the 5.1 kernel which was:
Files checked: 63848
Files with SPDX: 22576

This is a huge improvement.

Also, we deleted another 20000 lines of boilerplate license crud,
always nice to see in a diffstat"

Merge git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next

Pablo Neira Ayuso says:

====================
Netfilter updates for net-next

The following patchset contains a second batch of Netfilter updates for
your net-next tree. This includes a rework of the core hook
infrastructure that improves Netfilter performance by ~15% according to
synthetic benchmarks. Then, a large batch with ipset updates, including
a new hash:ipmac set type, via Jozsef Kadlecsik. This also includes a
couple of assorted updates.

Regarding the core hook infrastructure rework to improve performance,
using this simple drop-all packets ruleset from ingress:

nft add table netdev x
nft add chain netdev x y { type filter hook ingress device eth0 priority 0\; }
nft add rule netdev x y drop

And generating traffic through Jesper Brouer's
samples/pktgen/pktgen_bench_xmit_mode_netif_receive.sh script using -i
option. perf report shows nf_tables calls in its top 10:

17.30% kpktgend_0 [nf_tables] [k] nft_do_chain
15.75% kpktgend_0 [kernel.vmlinux] [k] __netif_receive_skb_core
10.39% kpktgend_0 [nf_tables_netdev] [k] nft_do_chain_netdev

I'm measuring here an improvement of ~15% in performance with this
patchset, so we got +2.5Mpps more. I have used my old laptop Intel(R)
Core(TM) i5-3320M CPU @ 2.60GHz 4-cores.

This rework contains more specifically, in strict order, these patches:

1) Remove compile-time debugging from core.

2) Remove obsolete comments that predate the rcu era. These days it is
well known that a Netfilter hook always runs under rcu_read_lock().

3) Remove threshold handling, this is only used by br_netfilter too.
We already have specific code to handle this from br_netfilter,
so remove this code from the core path.

4) Deprecate NF_STOP, as this is only used by br_netfilter.

5) Place nf_state_hook pointer into xt_action_param structure, so
this structure fits into one single cacheline according to pahole.
This also implicit affects nftables since it also relies on the
xt_action_param structure.

6) Move state->hook_entries into nf_queue entry. The hook_entries
pointer is only required by nf_queue(), so we can store this in the
queue entry instead.

7) use switch() statement to handle verdict cases.

8) Remove hook_entries field from nf_hook_state structure, this is only
required by nf_queue, so store it in nf_queue_entry structure.

9) Merge nf_iterate() into nf_hook_slow() that results in a much more
simple and readable function.

10) Handle NF_REPEAT away from the core, so far the only client is
nf_conntrack_in() and we can restart the packet processing using a
simple goto to jump back there when the TCP requires it.
This update required a second pass to fix fallout, fix from
Arnd Bergmann.

11) Set random seed from nft_hash when no seed is specified from
userspace.

12) Simplify nf_tables expression registration, in a much smarter way
to save lots of boiler plate code, by Liping Zhang.

13) Simplify layer 4 protocol conntrack tracker registration, from
Davide Caratti.

14) Missing CONFIG_NF_SOCKET_IPV4 dependency for udp4_lib_lookup, due
to recent generalization of the socket infrastructure, from Arnd
Bergmann.

15) Then, the ipset batch from Jozsef, he describes it as it follows:

* Cleanup: Remove extra whitespaces in ip_set.h
* Cleanup: Mark some of the helpers arguments as const in ip_set.h
* Cleanup: Group counter helper functions together in ip_set.h
* struct ip_set_skbinfo is introduced instead of open coded fields
in skbinfo get/init helper funcions.
* Use kmalloc() in comment extension helper instead of kzalloc()
because it is unnecessary to zero out the area just before
explicit initialization.
* Cleanup: Split extensions into separate files.
* Cleanup: Separate memsize calculation code into dedicated function.
* Cleanup: group ip_set_put_extensions() and ip_set_get_extensions()
together.
* Add element count to hash headers by Eric B Munson.
* Add element count to all set types header for uniform output
across all set types.
* Count non-static extension memory into memsize calculation for
userspace.
* Cleanup: Remove redundant mtype_expire() arguments, because
they can be get from other parameters.
* Cleanup: Simplify mtype_expire() for hash types by removing
one level of intendation.
* Make NLEN compile time constant for hash types.
* Make sure element data size is a multiple of u32 for the hash set
types.
* Optimize hash creation routine, exit as early as possible.
* Make struct htype per ipset family so nets array becomes fixed size
and thus simplifies the struct htype allocation.
* Collapse same condition body into a single one.
* Fix reported memory size for hash:* types, base hash bucket structure
was not taken into account.
* hash:ipmac type support added to ipset by Tomasz Chilinski.
* Use setup_timer() and mod_timer() instead of init_timer()
by Muhammad Falak R Wani, individually for the set type families.

16) Remove useless connlabel field in struct netns_ct, patch from
Florian Westphal.

17) xt_find_table_lock() doesn't return ERR_PTR() anymore, so simplify
{ip,ip6,arp}tables code that uses this.
