The following patchset contains Netfilter updates for net-next:

1) Add safeguard to check for NULL tupe in objects updates via
   NFT_MSG_NEWOBJ, this should not ever happen. From Alok Tiwari.

2) Incorrect pointer check in the new destroy rule command,
   from Yang Yingliang.

3) Incorrect status bitcheck in nf_conntrack_udp_packet(),
   from Florian Westphal.

4) Simplify seq_print_acct(), from Ilia Gavrilov.

5) Use 2-arg optimal variant of kfree_rcu() in IPVS,
   from Julian Anastasov.

6) TCP connection enters CLOSE state in conntrack for locally
   originated TCP reset packet from the reject target,
   from Florian Westphal.

The fixes #2 and #3 in this series address issues from the previous pull
nf-next request in this net-next cycle.

129ff4de58 net: microchip: sparx5: reduce stack usage
The vcap_admin structures in vcap_api_next_lookup_advanced_test()
take several hundred bytes of stack frame, but when CONFIG_KASAN_STACK
is enabled, each one of them also has extra padding before and after
it, which ends up blowing the warning limit:

In file included from drivers/net/ethernet/microchip/vcap/vcap_api.c:3521:

 1954 | }

Reduce the total stack usage by replacing the five structures with
an array that only needs one pair of padding areas.

a59f832a71 sfc: use IS_ENABLED() checks for CONFIG_SFC_SRIOV
One local variable has become unused after a recent change:

used, rather than adding another #ifdef.

This also fixes an uninitialized return value in ef100_probe_netdev_pf()

933a01ad59 octeontx2-af: Add NIX Errata workaround on CN10K silicon
This patch adds workaround for below 2 HW erratas

1. Due to improper clock gating, NIXRX may free the same
NPA buffer multiple times.. to avoid this, always enable
NIX RX conditional clock.

2. NIX FIFO does not get initialized on reset, if the SMQ
flush is triggered before the first packet is processed, it
will lead to undefined state. The workaround to perform SMQ
flush only if packet count is non-zero in MDQ.

c2a978c171 net: phy: Read EEE abilities when using .features
A PHY driver can use a static integer value to indicate what link mode
features it supports, i.e, its abilities.. This is the old way, but
useful when dynamically determining the devices features does not
work, e.g. support of fibre.

EEE support has been moved into phydev->supported_eee. This needs to
be set otherwise the code assumes EEE is not supported. It is normally
set as part of reading the devices abilities. However if a static
integer value was used, the dynamic reading of the abilities is not
performed. Add a call to genphy_c45_read_eee_abilities() to read the
EEE abilities.

Add additional phydev locks

The phydev lock should be held when accessing members of phydev, or
calling into the driver. Some of the phy_ethtool_ functions are

modified since it calls one of the functions which gain locks, which
would result in a deadlock.

The missing locks have not caused noticeable issues, so these patches

9f78bf330a xsk: support use vaddr as ring
When we try to start AF_XDP on some machines with long running time, due
to the machine's memory fragmentation problem, there is no sufficient
contiguous physical memory that will cause the start failure.

If the size of the queue is 8 * 1024, then the size of the desc[] is
8 * 1024 * 8 = 16 * PAGE, but we also add struct xdp_ring size, so it is
16page+. This is necessary to apply for a 4-order memory. If there are a
lot of queues, it is difficult to these machine with long running time.

Here, that we actually waste 15 pages. 4-Order memory is 32 pages, but
we only use 17 pages.

This patch replaces __get_free_pages() by vmalloc() to allocate memory
to solve these problems.

64cb6aad12 net/sched: taprio: dynamic max_sdu larger than the max_mtu is unlimited
It makes no sense to keep randomly large max_sdu values, especially if
larger than the device's max_mtu. These are visible in "tc qdisc show".
Such a max_sdu is practically unlimited and will cause no packets for
that traffic class to be dropped on enqueue.

Just set max_sdu_dynamic to U32_MAX, which in the logic below causes
taprio to save a max_frm_len of U32_MAX and a max_sdu presented to user
space of 0 (unlimited).

bdf366bd86 net/sched: taprio: don't allow dynamic max_sdu to go negative after stab adjustment
The overhead specified in the size table comes from the user. With small
time intervals (or gates always closed), the overhead can be larger than
the max interval for that traffic class, and their difference is
negative.

What we want to happen is for max_sdu_dynamic to have the smallest
non-zero value possible (1) which means that all packets on that traffic
class are dropped on enqueue. However, since max_sdu_dynamic is u32, a
negative is represented as a large value and oversized dropping never
happens.

Use max_t with int to force a truncation of max_frm_len to no smaller
than dev->hard_header_len + 1, which in turn makes max_sdu_dynamic no
smaller than 1.

09dbdf28f9 net/sched: taprio: fix calculation of maximum gate durations
taprio_calculate_gate_durations() depends on netdev_get_num_tc() and
this returns 0. So it calculates the maximum gate durations for no
traffic class.

I had tested the blamed commit only with another patch in my tree, one
which in the end I decided isn't valuable enough to submit ("net/sched:
taprio: mask off bits in gate mask that exceed number of TCs").

The problem is that having this patch threw off my testing. By moving
the netdev_set_num_tc() call earlier, we implicitly gave to
taprio_calculate_gate_durations() the information it needed.

Extract only the portion from the unsubmitted change which applies the
mqprio configuration to the netdev earlier.

c078381856 rxrpc: Fix overproduction of wakeups to recvmsg()
Fix three cases of overproduction of wakeups:

 (1) rxrpc_input_split_jumbo() conditionally notifies the app that there's
     data for recvmsg() to collect if it queues some data - and then its
     only caller, rxrpc_input_data(), goes and wakes up recvmsg() anyway.

     Fix the rxrpc_input_data() to only do the wakeup in failure cases.

 (2) If a DATA packet is received for a call by the I/O thread whilst
     recvmsg() is busy draining the call's rx queue in the app thread, the
     call will left on the recvmsg() queue for recvmsg() to pick up, even
     though there isn't any data on it.

     This can cause an unexpected recvmsg() with a 0 return and no MSG_EOR
     set after the reply has been posted to a service call.

     Fix this by discarding pending calls from the recvmsg() queue that
     don't need servicing yet.

 (3) Not-yet-completed calls get requeued after having data read from them,
     even if they have no data to read.

     Fix this by only requeuing them if they have data waiting on them; if
     they don't, the I/O thread will requeue them when data arrives or they
     fail.

====================
net: final GSI register updates

I believe this is the last set of changes required to allow IPA v5.0
to be supported.  There is a little cleanup work remaining, but that
can happen in the next Linux release cycle.  Otherwise we just need
config data and register definitions for IPA v5.0 (and DTS updates).
These are ready but won't be posted without further testing.

The first patch in this series fixes a minor bug in a patch just
posted, which I found too late.  The second eliminates the GSI
memory "adjustment"; this was done previously to avoid/delay the
need to implement a more general way to define GSI register offsets.
Note that this patch causes "checkpatch" warnings due to indentation
that aligns with an open parenthesis.

The third patch makes use of the newly-defined register offsets, to
eliminate the need for a function that hid a few details.  The next
modifies a different helper function to work properly for IPA v5.0+.
The fifth patch changes the way the event ring size is specified
based on how it's now done for IPA v5.0+.  And the last defines a
new register required for IPA v5.0+.

in place of ev_ch_e_cntxt_1_length_encode() (which can be removed).

59b12b1d27 net: ipa: kill gsi->virt_raw
Starting at IPA v4.5, almost all GSI registers had their offsets
changed by a fixed amount (shifted downward by 0xd000).  Rather than
defining offsets for all those registers dependent on version, an
adjustment was applied for most register accesses.  This was
implemented in commit cdeee49f3ef7f ("net: ipa: adjust GSI register
addresses").  It was later modified to be a bit more obvious about
the adjusment, in commit 571b1e7e58ad3 ("net: ipa: use a separate
pointer for adjusted GSI memory").

We now are able to define every GSI register with its own offset, so
there's no need to implement this special adjustment.

So get rid of the "virt_raw" pointer, and just maintain "virt" as
the (non-adjusted) base address of I/O mapped GSI register memory.

Redefine the offsets of all GSI registers (other than the INTER_EE
ones, which were not subject to the adjustment) for IPA v4.5+,
subtracting 0xd000 from their defined offsets instead.

Move the ERROR_LOG and ERROR_LOG_CLR definitions further down in the
register definition files so all registers are defined in order of
their offset.

ecfa80ce3b net: ipa: fix an incorrect assignment
I spotted an error in a patch posted this week, unfortunately just
after it got accepted.  The effect of the bug is that time-based
interrupt moderation is disabled.  This is not technically a bug,
but it is not what is intended.  The problem is that a |= assignment
got implemented as a simple assignment, so the previously assigned
value was ignored.

2954fe60e3 netfilter: let reset rules clean out conntrack entries
iptables/nftables support responding to tcp packets with tcp resets.

The generated tcp reset packet passes through both output and postrouting
netfilter hooks, but conntrack will never see them because the generated
skb has its ->nfct pointer copied over from the packet that triggered the
reset rule.

If the reset rule is used for established connections, this
may result in the conntrack entry to be around for a very long
time (default timeout is 5 days).

One way to avoid this would be to not copy the nf_conn pointer
so that the rest packet passes through conntrack too.

Problem is that output rules might not have the same conntrack
zone setup as the prerouting ones, so its possible that the
reset skb won't find the correct entry.  Generating a template
entry for the skb seems error prone as well.

Add an explicit "closing" function that switches a confirmed
conntrack entry to closed state and wire this up for tcp.

If the entry isn't confirmed, no action is needed because
the conntrack entry will never be committed to the table.

4a267bc5ea wifi: rtw88: use RTW_FLAG_POWERON flag to prevent to power on/off twice
Use power state to decide whether we can enter or leave IPS accurately,
and then prevent to power on/off twice.

The commit 6bf3a083407b ("wifi: rtw88: add flag check before enter or leave IPS")
would like to prevent this as well, but it still can't entirely handle all
cases. The exception is that WiFi gets connected and does suspend/resume,
it will power on twice and cause it failed to power on after resuming,
like:

  rtw_8723de 0000:03:00.0: failed to poll offset=0x6 mask=0x2 value=0x2
  rtw_8723de 0000:03:00.0: mac power on failed
  rtw_8723de 0000:03:00.0: failed to power on mac
  rtw_8723de 0000:03:00.0: leave idle state failed
  rtw_8723de 0000:03:00.0: failed to leave ips state
  rtw_8723de 0000:03:00.0: failed to leave idle state
  rtw_8723de 0000:03:00.0: failed to send h2c command

To fix this, introduce new flag RTW_FLAG_POWERON to reflect power state,
and call rtw_mac_pre_system_cfg() to configure registers properly between
power-off/-on.

b5596f1d54 spi: Update for v6.2
One more last minute patch for v6.2 updating the parsing of the
 newly added spi-cs-setup-delay-ns - it's been pointed out that
 due to the way DT parsing works the change in property size is
 ABI visible so let's not let a release go out without it being
 fixed.  The change got split from some earlier ABI related fixes
 to the property since the first version sent had a build error.
