Netfilter updates for net-next
The following series contains Netfilter updates for net-next:
1) Make legacy xtables configs user selectable, from Breno Leitao.
2) Fix a few sparse warnings related to percpu, from Uros Bizjak.
3) Use strscpy_pad, from Justin Stitt.
4) Use nft_trans_elem_alloc() in catchall flush, from Florian Westphal.
5) A series of 7 patches to fix false positive with CONFIG_RCU_LIST=y.
Florian also sees possible issue with 10 while module load/removal
when requesting an expression that is available via module. As for
patch 11, object is being updated so reference on the module already
exists so I don't see any real issue.
Florian says:
"Unfortunately there are many more errors, and not all are false positives.
First patches pass lockdep_commit_lock_is_held() to the rcu list traversal
macro so that those splats are avoided.
The last two patches are real code change as opposed to
'pass the transaction mutex to relax rcu check':
Those two lists are not protected by transaction mutex so could be altered
in parallel.
This targets nf-next because these are long-standing issues."

Add support to redirect host-to-BMC traffic by writing MACDA entries
from the RPC (RX Parser and Classifier) to TCE-TCAM. The TCE TCAM is a
small L2 destination TCAM which is placed at the end of the TX path (TCE).
Unlike other NICs, where BMC diversion is typically handled by firmware,
for fbnic, firmware does not touch anything related to the host; hence,
the host uses TCE TCAM to divert BMC traffic.
Currently, we lack metadata to track where addresses have been written
in the TCAM, except for the last entry written. To address this issue,
we start at the opposite end of the table in each pass, so that adding
or deleting entries does not affect the availability of all entries,
assuming there is no significant reordering of entries.

Add a 20-byte field ats to struct nfc_target and expose it as
NFC_ATTR_TARGET_ATS via the netlink interface. The payload contains
'historical bytes' that help to distinguish cards from one another.
The information is commonly used to assemble an emulated ATR similar
to that reported by smart cards with contacts.
Add a 20-byte field target_ats to struct nci_dev to hold the payload
obtained in nci_rf_intf_activated_ntf_packet() and copy it to over to
nfc_target.ats in nci_activate_target(). The approach is similar
to the handling of 'general bytes' within ATR_RES.
Replace the hard-coded size of rats_res within struct
activation_params_nfca_poll_iso_dep by the equal constant NFC_ATS_MAXSIZE
now defined in nfc.h
Within NCI, the information corresponds to the 'RATS Response' activation
parameter that omits the initial length byte TL. This loses no
information and is consistent with our handling of SENSB_RES that
also drops the first (constant) byte.
Tested with nxp_nci_i2c on a few type A targets including an
ICAO 9303 compliant passport.
I refrain from the corresponding change to digital_in_recv_ats()
to have the few drivers based on digital.h fill nfc_target.ats,
as I have no way to test it. That class of drivers appear not to set
NFC_ATTR_TARGET_SENSB_RES either. Consider a separate patch to propagate
(all) the parameters.

bnxt_en: ethtool: Improve wildcard l4proto on ip4/ip6 ntuple rules
This patchset improves wildcarding over l4proto on ip4 and ip6 nutple
rules. Previous support required setting l4proto explicitly to 0xFF if
you wanted wildcard, which ethtool (naturally) did not do. For example,
this command would fail with -EOPNOSUPP:
ethtool -N eth0 flow-type ip6 dst-ip $IP6 context 1
After this patchset, only TCP, UDP, ICMP, and unset will be supported
for l4proto.

Previously, trying to insert an ip4/ip6 ntuple rule with an unset
l4proto would get rejected with -EOPNOTSUPP. For example, the following
would fail:
ethtool -N eth0 flow-type ip6 dst-ip $IP6 context 1
The reason was that all the l4proto validation was being run despite the
l4proto mask being set to 0x0. Fix by respecting the mask on l4proto and
treating a mask of 0x0 as wildcard l4proto.

Add the dwmac driver support for T-HEAD TH1520 SoC
This series adds support for dwmac gigabit ethernet in the T-Head TH1520
RISC-V SoC used on boards like BeagleV Ahead and the LicheePi 4A.
The gigabit ethernet on these boards does need pinctrl support to mux
the necessary pads. The pinctrl-th1520 driver, pinctrl binding, and
related dts patches are in linux-next. However, they are not yet in
net-next/main.
Therefore, I am dropping the dts patch for v5 as it will not build on
net-next/main due to the lack of the padctrl0_apsys pin controller node
in next-next/main version th1520.dtsi. It does exist in linux-next [1]
and the two patches in this series allow the ethernet ports to work
correctly on the LPi4A and Ahead when applied to linux-next.
The dwmac-thead driver in this series does not need the pinctrl-th1520
driver to build. Nor does the thead,th1520-gmac.yaml binding need the
pinctrl binding to pass the schema check.

Clearing the secpath for internal ports will cause packet drops when
ipsec offload or early SW ipsec decrypt are used. Systems that rely
on these will not be able to actually pass traffic via openvswitch.
There is still an open issue for a flow miss packet - this is because
we drop the extensions during upcall and there is no facility to
restore such data (and it is non-trivial to add such functionality
to the upcall interface). That means that when a flow miss occurs,
there will still be packet drops. With this patch, when a flow is
found then traffic which has an associated xfrm extension will
properly flow.

====================
A pile of sfc deadcode
This is a collection of deadcode removal in the sfc
drivers; the split is vaguely where I found them in
the tree, with some left over.
This has been build tested and booted on an x86 VM,
but I fon't have the hardware to test; however
it's all full function removal.

efx_ticks_to_usecs(), efx_reconfigure_port(), efx_ptp_get_mode(), and
efx_tx_get_copy_buffer_limited() are unused.
They seem to be partially due to the later splits to Siena, but
some seem unused for longer.
Remove them.

efx_mcdi_flush_rxqs(), efx_mcdi_rpc_async_quiet(),

I think these are fall out from the split into Siena

conflicts with sfc")
and
commit d48523cb88 ("sfc: Copy shared files needed for Siena (part 2)")

We can see high contention on ptp_lock while doing RX timestamping
on high packet rates over several queues. Spinlock is not effecient
to protect timecounter for RX timestamps when reads are the most
usual operations and writes are only occasional. It's better to use
seqlock in such cases.

This hardware can provide only 48 bits of cycle counter. We can leave
only 24 bits in the cache to extend RX timestamps from 32 bits to 48
bits. Lower 8 bits of the cached value will be used to check for
roll-over while extending to full 48 bits.
This change makes cache writes atomic even on 32 bit platforms and we
can simply use READ_ONCE()/WRITE_ONCE() pair and remove spinlock. The
configuration structure will be also reduced by 4 bytes.

Recently, the net/lib.sh file has been modified to include defer.sh from
net/lib/sh/ directory. The Makefile from net/lib has been modified
accordingly, but not the ones from the sub-targets using net/lib.sh.
Because of that, the new file is not installed as expected when
installing the Forwarding, MPTCP, and Netfilter targets, e.g.
# make -C tools/testing/selftests TARGETS=net/mptcp install \
INSTALL_PATH=/tmp/kself
# cd /tmp/kself/
# ./run_kselftest.sh -c net/mptcp
TAP version 13
1..7
# timeout set to 1800
# selftests: net/mptcp: mptcp_connect.sh
# ./../lib.sh: line 5: /tmp/kself/net/lib/sh/defer.sh: No such file
or directory
# (...)
This can be fixed simply by adding all the .sh files from net/lib/sh
directory to the TEST_INCLUDES variable in the different Makefile's.
