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"

Some should cause changes in tooling, like the one adding LAST_EXCP, but
the way it is structured end up not making that happen.
The new SVM_EXIT_INVPCID should get used by arch/x86/util/kvm-stat.c,
in the svm_exit_reasons table.
The tools/perf/trace/beauty part has scripts to catch changes and
automagically create tables, like tools/perf/trace/beauty/kvm_ioctl.sh,
but changes are needed to make tools/perf/arch/x86/util/kvm-stat.c catch
those automatically.
These were handled by the existing scripts:

1595 | PyMODINIT_FUNC (*initfunc)(void);
| ^~~~~~~~~~~~~~
That started breaking when building with PYTHON=python3 and these gcc
versions (I haven't checked with the clang ones, maybe it breaks there
as well):
# export PERF_TARBALL=http://192.168.86.5/perf/perf-5.9.0.tar.xz

#
Avoid that by ditching that 'initfunc' function pointer with its:
#define Py_EXPORTED_SYMBOL _attribute_ ((visibility ("default")))
#define PyMODINIT_FUNC Py_EXPORTED_SYMBOL PyObject*
And just call PyImport_AppendInittab() at the end of the ifdef python3

The GCC specific __attribute__((optimize)) attribute does not what is
commonly expected and is explicitly recommended against using in
production code by the GCC people.
Unlike what is often expected, it doesn't add to the optimization flags,
but it fully replaces them, loosing any and all optimization flags
provided by the compiler commandline.
The only guaranteed upon means of inhibiting tail-calls is by placing a
volatile asm with side-effects after the call such that the tail-call simply
cannot be done.
Given the original commit wasn't specific on which calls were the problem, this
removal might re-introduce the problem, which can then be re-analyzed and cured
properly.

Ian reports an issue that the metric DRAM_BW_Use often remains 0.
The metric expression for DRAM_BW_Use on CLX/SKX:
"( 64 * ( uncore_imc@cas_count_read@ + uncore_imc@cas_count_write@ ) / 1000000000 ) / duration_time"
The counts of uncore_imc/cas_count_read/ and uncore_imc/cas_count_write/
are scaled up by 64, that is to turn a count of cache lines into bytes,
the count is then divided by 1000000000 to give GB.
However, the counts of uncore_imc/cas_count_read/ and
uncore_imc/cas_count_write/ have been scaled yet.
The scale values are from sysfs, such as
/sys/devices/uncore_imc_0/events/cas_count_read.scale.
It's 6.103515625e-5 (64 / 1024.0 / 1024.0).
So if we use original metric expression, the result is not correct.
But the difficulty is, for SKL client, the counts are not scaled.
The metric expression for DRAM_BW_Use on SKL:
"64 * ( arb@event\\=0x81\\,umask\\=0x1@ + arb@event\\=0x84\\,umask\\=0x1@ ) / 1000000 / duration_time / 1000"
root@kbl-ppc:~# perf stat -M DRAM_BW_Use -a -- sleep 1
Performance counter stats for 'system wide':
190 arb/event=0x84,umask=0x1/ # 1.86 DRAM_BW_Use
29,093,178 arb/event=0x81,umask=0x1/
1,000,703,287 ns duration_time
1.000703287 seconds time elapsed
The result is expected.
So the easy way is just change the metric expression for CLX/SKX.
This patch changes the metric expression to:
"( ( ( uncore_imc@cas_count_read@ + uncore_imc@cas_count_write@ ) * 1048576 ) / 1000000000 ) / duration_time"
1048576 = 1024 * 1024.
Before (tested on CLX):
root@lkp-csl-2sp5 ~# perf stat -M DRAM_BW_Use -a -- sleep 1
Performance counter stats for 'system wide':
765.35 MiB uncore_imc/cas_count_read/ # 0.00 DRAM_BW_Use
5.42 MiB uncore_imc/cas_count_write/
1001515088 ns duration_time
1.001515088 seconds time elapsed
After:
root@lkp-csl-2sp5 ~# perf stat -M DRAM_BW_Use -a -- sleep 1
Performance counter stats for 'system wide':
767.95 MiB uncore_imc/cas_count_read/ # 0.80 DRAM_BW_Use

The addr in PERF_RECORD_KSYMBOL events for non-jited bpf progs points to
the bpf interpreter, ie. within kernel text section. When processing the
unregister event, this causes unexpected removal of vmlinux_map,
crashing perf later in cleanup:

Since commit 9a40401cfa13 ("lib/scatterlist: Do not limit max_segment to
PAGE_ALIGNED values") the max_segment input to sg_alloc_table_from_pages()
does not have to be any special value. The new algorithm will always
create something less than what the user provides. Thus eliminate this
confusing constant.
- vmwgfx should use the HW capability, not mix in the OS page size for
calling dma_set_max_seg_size()
- i915 uses i915_sg_segment_size() both for sg_alloc_table_from_pages
and for some open coded sgl construction. This doesn't change the value
since rounddown(size, UINT_MAX) == SCATTERLIST_MAX_SEGMENT
- drm_prime_pages_to_sg uses it as a default if max_segment is zero,
UINT_MAX is fine to use directly.

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.

The kernel-doc markups there is violating the expected
syntax, causing it to not parse the name of the
markup identifier properly, preventing it to check
if the kernel-doc matches the #define below each
markup.

[...]
# pidfd_send_signal signal recycled pid test: Skipping test
# Planned tests != run tests (8 != 7)
# Totals: pass:7 fail:0 xfail:0 xpass:0 skip:0 error:0
Fix by using ksft_test_result_skip():
$ ./pidfd_test
TAP version 13
1..8
[...]
ok 8 # SKIP pidfd_send_signal signal recycled pid test: Unsharing pid namespace not permitted
# Totals: pass:7 fail:0 xfail:0 xpass:0 skip:1 error:0
