Pull networking fixes from Paolo Abeni:
"Including fixes from can, bluetooth and ipsec.

This contains a last minute revert of a recent GRE patch, mostly to
allow me stating there are no known regressions outstanding.

Current release - regressions:

- revert "gre: Fix IPv6 link-local address generation."

- eth: ti: am65-cpsw: fix NAPI registration sequence

Previous releases - regressions:

- ipv6: fix memleak of nhc_pcpu_rth_output in fib_check_nh_v6_gw().

- mptcp: fix data stream corruption in the address announcement

- bluetooth: fix connection regression between LE and non-LE adapters

- can:
- flexcan: only change CAN state when link up in system PM
- ucan: fix out of bound read in strscpy() source

Previous releases - always broken:

- lwtunnel: fix reentry loops

- ipv6: fix TCP GSO segmentation with NAT

- xfrm: force software GSO only in tunnel mode

- eth: ti: icssg-prueth: add lock to stats

Misc:

- add Andrea Mayer as a maintainer of SRv6"

Merge branch 'net-fix-lwtunnel-reentry-loops'

Justin Iurman says:

====================
net: fix lwtunnel reentry loops

When the destination is the same after the transformation, we enter a
lwtunnel loop. This is true for most of lwt users: ioam6, rpl, seg6,
seg6_local, ila_lwt, and lwt_bpf. It can happen in their input() and
output() handlers respectively, where either dst_input() or dst_output()
is called at the end. It can also happen in xmit() handlers.

Here is an example for rpl_input():

dump_stack_lvl+0x60/0x80
rpl_input+0x9d/0x320
lwtunnel_input+0x64/0xa0
lwtunnel_input+0x64/0xa0
lwtunnel_input+0x64/0xa0
lwtunnel_input+0x64/0xa0
lwtunnel_input+0x64/0xa0
[...]
lwtunnel_input+0x64/0xa0
lwtunnel_input+0x64/0xa0
lwtunnel_input+0x64/0xa0
lwtunnel_input+0x64/0xa0
lwtunnel_input+0x64/0xa0
ip6_sublist_rcv_finish+0x85/0x90
ip6_sublist_rcv+0x236/0x2f0

... until rpl_do_srh() fails, which means skb_cow_head() failed.

This series provides a fix at the core level of lwtunnel to catch such
loops when they're not caught by the respective lwtunnel users, and
handle the loop case in ioam6 which is one of the users. This series
also comes with a new selftest to detect some dst cache reference loops
in lwtunnel users.

selftests: net: test for lwtunnel dst ref loops

As recently specified by commit 0ea09cbf8350 ("docs: netdev: add a note
on selftest posting") in net-next, the selftest is therefore shipped in
this series. However, this selftest does not really test this series. It
needs this series to avoid crashing the kernel. What it really tests,
thanks to kmemleak, is what was fixed by the following commits:
- commit c71a192976de ("net: ipv6: fix dst refleaks in rpl, seg6 and
ioam6 lwtunnels")
- commit 92191dd10730 ("net: ipv6: fix dst ref loops in rpl, seg6 and
ioam6 lwtunnels")
- commit c64a0727f9b1 ("net: ipv6: fix dst ref loop on input in seg6
lwt")
- commit 13e55fbaec17 ("net: ipv6: fix dst ref loop on input in rpl
lwt")
- commit 0e7633d7b95b ("net: ipv6: fix dst ref loop in ila lwtunnel")
- commit 5da15a9c11c1 ("net: ipv6: fix missing dst ref drop in ila
lwtunnel")
