Renaming interfaces using udevd depends on the interface being registered
before its netdev is registered. Otherwise, udevd reads an empty
phys_port_name value, resulting in the interface not being renamed.

Fix this by registering the interface before registering its netdev
by invoking am65_cpsw_nuss_register_devlink() before invoking
register_netdev() for the interface.

Move the function call to devlink_port_type_eth_set(), invoking it after
register_netdev() is invoked, to ensure that netlink notification for the
port state change is generated after the netdev is completely initialized.

There is a long-standing issue with the Synopsys DWC Ethernet driver
for Tegra194 where random system crashes have been observed [0]. The
problem occurs when the split header feature is enabled in the stmmac
driver. In the bad case, a larger than expected buffer length is
received and causes the calculation of the total buffer length to
overflow. This results in a very large buffer length that causes the
kernel to crash. Why this larger buffer length is received is not clear,
however, the feedback from the NVIDIA design team is that the split
header feature is not supported for Tegra194. Therefore, disable split
header support for Tegra194 to prevent these random crashes from
occurring.

These are indeed "should not happen" situations, but it turns out recent
changes made the 'task_is_stopped_or_trace()' case trigger (fix for that
exists, is pending more testing), and the BUG_ON() makes it
unnecessarily hard to actually debug for no good reason.

It's been that way for a long time, but let's make it clear: BUG_ON() is
not good for debugging, and should never be used in situations where you
could just say "this shouldn't happen, but we can continue".

Use WARN_ON_ONCE() instead to make sure it gets logged, and then just
continue running.  Instead of making the system basically unusuable
because you crashed the machine while potentially holding some very core
locks (eg this function is commonly called while holding 'tasklist_lock'
for writing).

wireguard patches for 5.19-rc6

1) A few small fixups to the selftests, per usual. Of particular note is
   a fix for a test flake that occurred on especially fast systems that
   boot in less than a second.

2) An addition during this cycle of some s390 crypto interacted with the

   reported by the kernel test robot. So Vladis sent in a patch for
   that, which also required a small preparatory fix moving some Kconfig

Not all platforms have an RTC, and rather than trying to force one into

because WireGuard's latest handshakes parameter is returned in wallclock
time, and if the system time isn't set, and the system is really fast,
then this returns 0, which trips the test.

There are UAF bugs caused by rose_t0timer_expiry(). The
root cause is that del_timer() could not stop the timer
handler that is running and there is no synchronization.
One of the race conditions is shown below:

    (thread 1)             |        (thread 2)
                           | rose_device_event

                           |     rose_remove_neigh
rose_t0timer_expiry        |       rose_stop_t0timer(rose_neigh)
  ...                      |         del_timer(&neigh->t0timer)
                           |         kfree(rose_neigh) //[1]FREE
  neigh->dce_mode //[2]USE |

The rose_neigh is deallocated in position [1] and use in
position [2].

The crash trace triggered by POC is like below:

This patch changes rose_stop_ftimer() and rose_stop_t0timer()

timer handler could be finished before the resources such as
rose_neigh and so on are deallocated. As a result, the UAF
bugs could be mitigated.

anything protected by the PM lock, and it must release and reacquire

By pushing the PM lock to where it is needed in mptcp_pm_nl_fullmesh(),
the lock is only acquired when the fullmesh flag is changed and the
backup flag code no longer has to release and reacquire the PM lock. The
change in locking context requires the MIB update to be modified - move
that to a better location instead.

Instead of counting the child nodes in the device tree, hardcode the
number of ports in the driver itself.  The counting won't work at all
if an ethernet port is marked as disabled, e.g. because it is not
connected on the board at all.

It turns out that the LAN9662 and LAN9668 use the same switching IP
with the same synthesis parameters. The only difference is that the
output ports are not connected. Thus, we can just hardcode the
number of physical ports to 8.

`cancel_work_sync(&hdev->power_on)` was moved to hci_dev_close_sync in
commit [1] to ensure that power_on work is canceled after HCI interface
down.

But, in certain cases power_on work function may call hci_dev_close_sync
itself: hci_power_on -> hci_dev_do_close -> hci_dev_close_sync ->
cancel_work_sync(&hdev->power_on), causing deadlock. In particular, this
happens when device is rfkilled on boot. To avoid deadlock, move
power_on work canceling out of hci_dev_do_close/hci_dev_close_sync.

Deadlock introduced by commit [1] was reported in [2,3] as broken
suspend. Suspend did not work because `hdev->req_lock` held as result of
`power_on` work deadlock. In fact, other BT features were not working.
It was not observed when testing [1] since it was verified without
rfkill in place.

NOTE: It is not needed to cancel power_on work from other places where
hci_dev_do_close/hci_dev_close_sync is called in case:
* Requests were serialized due to `hdev->req_workqueue`. The power_on
work is first in that workqueue.
* hci_rfkill_set_block which won't close device anyway until HCI_SETUP
is on.
* hci_sock_release which runs after hci_sock_bind which ensures
HCI_SETUP was cleared.

As result, behaviour is the same as in pre-dd06ed7 commit, except
power_on work cancel added to hci_dev_close.

Pull xen security fixes from Juergen Gross:

 - XSA-403 (4 patches for blkfront and netfront drivers):

   Linux Block and Network PV device frontends don't zero memory regions
   before sharing them with the backend (CVE-2022-26365,
   CVE-2022-33740). Additionally the granularity of the grant table
   doesn't allow sharing less than a 4K page, leading to unrelated data
   residing in the same 4K page as data shared with a backend being
   accessible by such backend (CVE-2022-33741, CVE-2022-33742).

 - XSA-405 (1 patch for netfront driver, only 5.10 and newer):

   While adding logic to support XDP (eXpress Data Path), a code label
   was moved in a way allowing for SKBs having references (pointers)
   retained for further processing to nevertheless be freed.

 - XSA-406 (1 patch for Arm specific dom0 code):

   When mapping pages of guests on Arm, dom0 is using an rbtree to keep
   track of the foreign mappings.

   Updating of that rbtree is not always done completely with the
   related lock held, resulting in a small race window, which can be
   used by unprivileged guests via PV devices to cause inconsistencies
   of the rbtree. These inconsistencies can lead to Denial of Service
   (DoS) of dom0, e.g. by causing crashes or the inability to perform
   further mappings of other guests' memory pages.

The previous cleanup with devres may lead to the incorrect release
orders at the probe error handling due to the devres's nature.  Until
we register the card, snd_card_free() has to be called at first for
releasing the stuff properly when the driver tries to manage and
release the stuff via card->private_free().

This patch fixes it by calling snd_card_free() manually on the error
from the probe callback.

====================
Fix bridge_vlan_aware.sh and bridge_vlan_unaware.sh with IFF_UNICAST_FLT

Make sure that h1 and h2 don't drop packets with a random MAC DA, which
otherwise confuses these selftests. Also, fix an incorrect error message
found during those failures.

When packets are not received, they aren't received on $host1_if, so the
message talking about the second host not receiving them is incorrect.
Fix it.

The first host interface has by default no interest in receiving packets
MAC DA de:ad:be:ef:13:37, so it might drop them before they hit the tc
filter and this might confuse the selftest.

Enable promiscuous mode such that the filter properly counts received
packets.

As mentioned in the blamed commit, flood_unicast_test() works by
checking the match count on a tc filter placed on the receiving
interface.

But the second host interface (host2_if) has no interest in receiving a
packet with MAC DA de:ad:be:ef:13:37, so its RX filter drops it even
before the ingress tc filter gets to be executed. So we will incorrectly
get the message "Packet was not flooded when should", when in fact, the
packet was flooded as expected but dropped due to an unrelated reason,
at some other layer on the receiving side.

Force h2 to accept this packet by temporarily placing it in promiscuous
mode. Alternatively we could either deliver to its MAC address or use
tcpdump_start, but this has the fewest complications.

This fixes the "flooding" test from bridge_vlan_aware.sh and
bridge_vlan_unaware.sh, which calls flood_test from the lib.

====================
can 2022-07-04

The 1st patch is by Oliver Hartkopp, targets the BCM CAN protocol and
converts a costly synchronize_rcu() to call_rcu() to fix a performance
regression.

Srinivas Neeli's patch for the xilinx_can driver drops the brp limit
down to 1, as only the pre-production silicon have an issue with a brp
of 1.

The next patch is by Duy Nguyen and fixes the data transmission on
R-Car V3U SoCs in the rcar_canfd driver.

Rhett Aultman's patch fixes a DMA memory leak in the gs_usb driver.

Liang He's patch removes an extra of_node_get() in the grcan driver.

The next 2 patches are by me, target the m_can driver and fix the
timestamp handling used for peripheral devices like the tcan4x5x.

Jimmy Assarsson contributes 3 patches for the kvaser_usb driver and
fixes CAN clock and bit timing related issues.

The remaining 5 patches target the mcp251xfd driver. Thomas Kopp
contributes 2 patches to improve the workaround for broken CRC when
reading the TBC register. 3 patches by me add a missing
hrtimer_cancel() during the ndo_stop() callback, and fix the reading
of the Device ID register.
