vif_dev_read() should be used from RCU protected sections only.

6deb209dc6 net: Print hashed skb addresses for all net and qdisc events
The following commits added support for printing the real address-
65875073eddd ("net: use %px to print skb address in trace_netif_receive_skb")
70713dddf3d2 ("net_sched: introduce tracepoint trace_qdisc_enqueue()")
851f36e40962 ("net_sched: use %px to print skb address in trace_qdisc_dequeue()")

However, tracing the packet traversal shows a mix of hashes and real
addresses. Pasting a sample trace for reference-

ping-14249   [002] .....  3424.046612: netif_rx_entry: dev=lo napi_id=0x3 queue_mapping=0

ping-14249   [002] .....  3424.046615: netif_rx: dev=lo skbaddr=ffffff888e5d1000 len=84

Switch the trace print formats to %p for all the events to have a
consistent format of printing the hashed addresses in all cases.

Merge tag 'linux-can-next-for-5.20-20220625' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next

Marc Kleine-Budde says:

====================
pull-request: can-next 2022-06-25

this is a pull request of 22 patches for net-next/master.

The first 2 patches target the xilinx driver. Srinivas Neeli's patch
adds Transmitter Delay Compensation (TDC) support, a patch by me fixes
a typo.

The next patch is by me and fixes a typo in the m_can driver.

Another patch by me allows the configuration of fixed bit rates
without need for do_set_bittiming callback.

The following 7 patches are by Vincent Mailhol and refactor the
can-dev module and Kbuild, de-inline the can_dropped_invalid_skb()
function, which has grown over the time, and drop outgoing skbs if the
controller is in listen only mode.

Max Staudt's patch fixes a reference in the networking/can.rst
documentation.

Vincent Mailhol provides 2 patches with cleanups for the etas_es58x
driver.

Conor Dooley adds bindings for the mpfs-can to the PolarFire SoC dtsi.

Another patch by me allows the configuration of fixed data bit rates
without need for do_set_data_bittiming callback.

The last 5 patches are by Frank Jungclaus. They prepare the esd_usb
driver to add support for the the CAN-USB/3 device in a later series.

Clément Léger says:

====================
net: add support for Renesas RZ/N1 ethernet su

The Renesas RZ/N1 SoCs features an ethernet subsystem which contains
(most notably) a switch, two GMACs, and a MII converter [1]. This
series adds support for the switch and the MII converter.

The MII converter present on this SoC has been represented as a PCS
which sit between the MACs and the PHY. This PCS driver is probed from
the device-tree since it requires to be configured. Indeed the MII
converter also contains the registers that are handling the muxing of
ports (Switch, MAC, HSR, RTOS, etc) internally to the SoC.

The switch driver is based on DSA and exposes 4 ports + 1 CPU
management port. It include basic bridging support as well as FDB and
statistics support.

1c6e8088d9 net: dsa: allow port_bridge_join() to override extack message
Some drivers might report that they are unable to bridge ports by
returning -EOPNOTSUPP, but still wants to override extack message.
In order to do so, in dsa_slave_changeupper(), if port_bridge_join()
returns -EOPNOTSUPP, check if extack message is set and if so, do not
override it.

c3d396120d Merge branch 'preparation-for-supporting-esd-CAN-USB-3'
Frank Jungclaus says:
====================
All following 5 patches must be seen as preparation for adding support
of the newly available esd CAN-USB/3 to esd_usb2.c.

After having gained some confidence and experience on sending patches
to linux-can@vger.kernel.org, I'll again submit the code changes for
CAN-USB/3 support as step #2.

a69e617e53 usbnet: Fix linkwatch use-after-free on disconnect
usbnet uses the work usbnet_deferred_kevent() to perform tasks which may
sleep.  On disconnect, completion of the work was originally awaited in
->ndo_stop().  But in 2003, that was moved to ->disconnect() by historic
commit "[PATCH] USB: usbnet, prevent exotic rtnl deadlock":

  https://git.kernel.org/tglx/history/c/0f138bbfd83c

The change was made because back then, the kernel's workqueue
implementation did not allow waiting for a single work.  One had to wait
for completion of *all* work by calling flush_scheduled_work(), and that
could deadlock when waiting for usbnet_deferred_kevent() with rtnl_mutex
held in ->ndo_stop().

The commit solved one problem but created another:  It causes a
use-after-free in USB Ethernet drivers aqc111.c, asix_devices.c,
ax88179_178a.c, ch9200.c and smsc75xx.c:

* If the drivers receive a link change interrupt immediately before
  disconnect, they raise EVENT_LINK_RESET in their (non-sleepable)
  ->status() callback and schedule usbnet_deferred_kevent().
* usbnet_deferred_kevent() invokes the driver's ->link_reset() callback,
  which calls netif_carrier_{on,off}().
* That in turn schedules the work linkwatch_event().

Because usbnet_deferred_kevent() is awaited after unregister_netdev(),
netif_carrier_{on,off}() may operate on an unregistered netdev and
linkwatch_event() may run after free_netdev(), causing a use-after-free.

In 2010, usbnet was changed to only wait for a single instance of
usbnet_deferred_kevent() instead of *all* work by commit 23f333a2bfaf
("drivers/net: don't use flush_scheduled_work()").

Unfortunately the commit neglected to move the wait back to
->ndo_stop().  Rectify that omission at long last.

7dd1964806 mlxsw: spectrum: Change mlxsw_sp_rif_vlan_fid_op() to be dedicated for FID RIFs
The function was designed to configure both VLAN and FID RIFs, but
currently the driver does not use VLAN RIFs. Instead, it emulates VLAN
RIFs using FID RIFs.

As part of the conversion to the unified bridge model, the driver will
need to use VLAN RIFs, but they will be configured differently from FID
RIFs.

As a preparation for this change, rename the function to reflect the
fact that it is specific to FID RIFs and do not pass the RIF type as an
argument.

This leaves mlxsw_reg_ritr_fid_set() unused, so remove it.
