Pull networking fixes from Jakub Kicinski:
"Networking fixes for 5.10-rc3, including fixes from wireless, can, and
netfilter subtrees.
Current merge window - bugs in new features:
- can: isotp: isotp_rcv_cf(): enable RX timeout handling in
listen-only mode
Previous releases - regressions:
- mac80211:
- don't require VHT elements for HE on 2.4 GHz
- fix regression where EAPOL frames were sent in plaintext
- netfilter:
- ipset: Update byte and packet counters regardless of whether
they match
- ip_tunnel: fix over-mtu packet send by allowing fragmenting even if
inner packet has IP_DF (don't fragment) set in its header (when
TUNNEL_DONT_FRAGMENT flag is not set on the tunnel dev)
- net: fec: fix MDIO probing for some FEC hardware blocks
- ip6_tunnel: set inner ipproto before ip6_tnl_encap to un-break gso
support
- sctp: Fix COMM_LOST/CANT_STR_ASSOC err reporting on big-endian
platforms, sparse-related fix used the wrong integer size
Previous releases - always broken:
- netfilter: use actual socket sk rather than skb sk when routing
harder
- r8169: work around short packet hw bug on RTL8125 by padding frames
- net: ethernet: ti: cpsw: disable PTPv1 hw timestamping
advertisement, the hardware does not support it
- chelsio/chtls: fix always leaking ctrl_skb and another leak caused
by a race condition
- fix drivers incorrectly writing into skbs on TX:
- cadence: force nonlinear buffers to be cloned
- gianfar: Account for Tx PTP timestamp in the skb headroom
- gianfar: Replace skb_realloc_headroom with skb_cow_head for PTP
- can: flexcan:
- remove FLEXCAN_QUIRK_DISABLE_MECR quirk for LS1021A
- add ECC initialization for VF610 and LX2160A
- flexcan_remove(): disable wakeup completely
- can: fix packet echo functionality:
- peak_canfd: fix echo management when loopback is on
- make sure skbs are not freed in IRQ context in case they need to
be dropped
- always clone the skbs to make sure they have a reference on the
socket, and prevent it from disappearing
- fix real payload length return value for RTR frames
- can: j1939: return failure on bind if netdev is down, rather than
waiting indefinitely
Misc:
- IPv6: reply ICMP error if the first fragment don't include all
headers to improve compliance with RFC 8200"

Unless we want to test with THP, then we shouldn't require it to be
configured by the host kernel. Unfortunately, even advising with
MADV_NOHUGEPAGE does require it, so check for THP first in order
to avoid madvise failing with EINVAL.

Add a regression test for commit 671ddc700fd0 ("KVM: nVMX: Don't leak
L1 MMIO regions to L2").
First, check to see that an L2 guest can be launched with a valid
APIC-access address that is backed by a page of L1 physical memory.
Next, set the APIC-access address to a (valid) L1 physical address
that is not backed by memory. KVM can't handle this situation, so
resuming L2 should result in a KVM exit for internal error
(emulation).

If netfilter changes the packet mark, the packet is rerouted. The
ip_route_me_harder family of functions fails to use the right sk, opting
to instead use skb->sk, resulting in a routing loop when used with
tunnels. With the next change fixing this issue in netfilter, test for
the relevant condition inside our test suite, since wireguard was where
the bug was discovered.

Commit cad6967ac108 ("fork: introduce kernel_clone()") replaced "_do_fork()"
with "kernel_clone()". The ftrace selftests reference the fork function in
several of the tests. The rename will make the tests break, but if those
names are changed in the tests, they would then break on older kernels. The
same set of tests should pass older kernels if they have previously passed.
Obviously, a new test may not work on older kernels if the test was added
due to a bug or a new feature.
The setup of ftracetest will now create a $FUNCTION_FORK bash variable
that will contain "_do_fork" for older kernels and "kernel_clone" for newer
ones. It figures out the proper name by examining /proc/kallsyms.
Note, available_filter_functions could also be used, but because some tests
should be able to pass without function tracing enabled, it could not be
used.

"Cross-tree/merge window issues:
- rtl8150: don't incorrectly assign random MAC addresses; fix late in

Current release regressions:
- Revert "virtio-net: ethtool configurable RXCSUM", it was causing
crashes at probe when control vq was not negotiated/available
Previous release regressions:
- ixgbe: fix probing of multi-port 10 Gigabit Intel NICs with an MDIO
bus, only first device would be probed correctly
- nexthop: Fix performance regression in nexthop deletion by
effectively switching from recently added synchronize_rcu() to
synchronize_rcu_expedited()
- netsec: ignore 'phy-mode' device property on ACPI systems; the
property is not populated correctly by the firmware, but firmware

bulk transfers getting "stuck"
- icmp: randomize the global rate limiter to prevent attackers from
getting useful signal
- r8169: fix operation under forced interrupt threading, make the
driver always use hard irqs, even on RT, given the handler is light

- bpf: improve just-added bpf_redirect_neigh() helper api to support

done a lookup we can avoid doing another one

the existing MMU's bells and whistles. However it is a very solid
piece of work and it is already available for people to hammer on it.

- Introduction of a new EL2-private host context
- Allow EL2 to have its own private per-CPU variables
- Support of PMU event filtering
- Complete rework of the Spectre mitigation
PPC:
- Fix for running nested guests with in-kernel IRQ chip
- Fix race condition causing occasional host hard lockup
- Minor cleanups and bugfixes
x86:
- allow trapping unknown MSRs to userspace
- allow userspace to force #GP on specific MSRs

Recently, CONFIG_MPTCP_IPV6 no longer selects CONFIG_IPV6. As a
consequence, if CONFIG_MPTCP_IPV6=y is added to the kconfig, it will no
longer ensure CONFIG_IPV6=y. If it is not enabled, CONFIG_MPTCP_IPV6
will stay disabled and selftests will fail.
We also need CONFIG_IPV6 to be built-in. For more details, please see
commit 0ed37ac586c0 ("mptcp: depends on IPV6 but not as a module").
Note that 'make kselftest-merge' will take all 'config' files found in
'tools/testsing/selftests'. Because some of them already set
CONFIG_IPV6=y, MPTCP selftests were still passing. But they will fail if
MPTCP selftests are launched manually after having executed this command
to prepare the kernel config:
./scripts/kconfig/merge_config.sh -m .config \
./tools/testing/selftests/net/mptcp/config

This updates the test_tc_neigh prog in selftests to use the new syntax of
bpf_redirect_neigh(). To exercise the helper both with and without the
optional parameter, add an additional test_tc_neigh_fib test program, which
does a bpf_fib_lookup() followed by a call to bpf_redirect_neigh() instead
of looking up the ifindex in a map.
Update the test_tc_redirect.sh script to run both versions of the test,
and while we're add it, fix it to work on systems that have a consolidated
dual-stack 'ping' binary instead of separate ping/ping6 versions.

The kci_test_encap_fou() test from kci_test_encap() in rtnetlink.sh
needs the fou module to work. Otherwise it will fail with:
$ ip netns exec "$testns" ip fou add port 7777 ipproto 47

Error talking to the kernel
Add the CONFIG_NET_FOU into the config file as well. Which needs at

workaround
alignment_handler currently only tests the unaligned cases but it can
also be useful for testing the workaround for the P9N DD2.1 vector CI
load issue fixed by p9_hmi_special_emu(). This workaround was
introduced in 5080332c2c89 ("powerpc/64s: Add workaround for P9 vector
CI load issue").
This changes the loop to start from offset 0 rather than 1 so that we
test the kernel emulation in p9_hmi_special_emu().

This is the first step in transitioning to dispatching all KUnit
tests from a centralized executor rather than having each as its own
separate late_initcall.
