====================
pull-request: can 2023-07-17
The 1st patch is by Ziyang Xuan and fixes a possible memory leak in
the receiver handling in the CAN RAW protocol.
YueHaibing contributes a use after free in bcm_proc_show() of the
Broad Cast Manager (BCM) CAN protocol.
The next 2 patches are by me and fix a possible null pointer
dereference in the RX path of the gs_usb driver with activated
hardware timestamps and the candlelight firmware.
The last patch is by Fedor Ross, Marek Vasut and me and targets the
mcp251xfd driver. The polling timeout of __mcp251xfd_chip_set_mode()
is increased to fix bus joining on busy CAN buses and very low bit
rate.

When looking at the TC selftest reports, I noticed one test was failing
because /proc/net/nf_conntrack was not available.

Could not match regex pattern. Verify command output:
cat: /proc/net/nf_conntrack: No such file or directory
It is only available if NF_CONNTRACK_PROCFS kconfig is set. So the issue
can be fixed simply by adding it to the list of required kconfig.

Cited commit converted the neighbour code to use the standard RCU
variant instead of the RCU-bh variant, but the VRF code still uses
rcu_read_lock_bh() / rcu_read_unlock_bh() around the neighbour lookup
code in its IPv4 and IPv6 output paths, resulting in lockdep splats
[1][2]. Can be reproduced using [3].
Fix by switching to rcu_read_lock() / rcu_read_unlock().

The mcp251xfd controller needs an idle bus to enter 'Normal CAN 2.0
mode' or . The maximum length of a CAN frame is 736 bits (64 data
bytes, CAN-FD, EFF mode, worst case bit stuffing and interframe
spacing). For low bit rates like 10 kbit/s the arbitrarily chosen
MCP251XFD_POLL_TIMEOUT_US of 1 ms is too small.
Otherwise during polling for the CAN controller to enter 'Normal CAN
2.0 mode' the timeout limit is exceeded and the configuration fails
with:
| $ ip link set dev can1 up type can bitrate 10000
| [ 731.911072] mcp251xfd spi2.1 can1: Controller failed to enter mode CAN 2.0 Mode (6) and stays in Configuration Mode (4) (con=0x068b0760, osc=0x00000468).

| RTNETLINK answers: Connection timed out
Make MCP251XFD_POLL_TIMEOUT_US timeout calculation dynamic. Use
maximum of 1ms and bit time of 1 full 64 data bytes CAN-FD frame in
EFF mode, worst case bit stuffing and interframe spacing at the
current bit rate.
For easier backporting define the macro MCP251XFD_FRAME_LEN_MAX_BITS
that holds the max frame length in bits, which is 736. This can be
replaced by can_frame_bits(true, true, true, true, CANFD_MAX_DLEN) in
a cleanup patch later.

Marc Kleine-Budde <mkl@pengutronix.de> says:
During testing I noticed a crash if unloading/loading the gs_usb
driver during high CAN bus load.
The current version of the candlelight firmware doesn't flush the
queues of the received CAN frames during the reset command. This leads
to a crash if hardware timestamps are enabled, and an URB from the
device is received before the cycle counter/time counter
infrastructure has been setup.
First clean up then error handling in gs_can_open().
Then, fix the problem by converting the cycle counter/time counter
infrastructure from a per-channel to per-device and set it up before
submitting RX-URBs to the USB stack.

If the gs_usb device driver is unloaded (or unbound) before the
interface is shut down, the USB stack first calls the struct
usb_driver::disconnect and then the struct net_device_ops::ndo_stop
callback.
In gs_usb_disconnect() all pending bulk URBs are killed, i.e. no more
RX'ed CAN frames are send from the USB device to the host. Later in
gs_can_close() a reset control message is send to each CAN channel to
remove the controller from the CAN bus. In this race window the USB
device can still receive CAN frames from the bus and internally queue
them to be send to the host.
At least in the current version of the candlelight firmware, the queue
of received CAN frames is not emptied during the reset command. After
loading (or binding) the gs_usb driver, new URBs are submitted during
the struct net_device_ops::ndo_open callback and the candlelight
firmware starts sending its already queued CAN frames to the host.
However, this scenario was not considered when implementing the
hardware timestamp function. The cycle counter/time counter
infrastructure is set up (gs_usb_timestamp_init()) after the USBs are
submitted, resulting in a NULL pointer dereference if
timecounter_cyc2time() (via the call chain:
gs_usb_receive_bulk_callback() -> gs_usb_set_timestamp() ->
gs_usb_skb_set_timestamp()) is called too early.
Move the gs_usb_timestamp_init() function before the URBs are
submitted to fix this problem.
For a comprehensive solution, we need to consider gs_usb devices with
more than 1 channel. The cycle counter/time counter infrastructure is
setup per channel, but the RX URBs are per device. Once gs_can_open()
of _a_ channel has been called, and URBs have been submitted, the
gs_usb_receive_bulk_callback() can be called for _all_ available
channels, even for channels that are not running, yet. As cycle
counter/time counter has not set up, this will again lead to a NULL
pointer dereference.
Convert the cycle counter/time counter from a "per channel" to a "per
device" functionality. Also set it up, before submitting any URBs to
the device.
Further in gs_usb_receive_bulk_callback(), don't process any URBs for
not started CAN channels, only resubmit the URB.

The gs_usb driver handles USB devices with more than 1 CAN channel.
The RX path for all channels share the same bulk endpoint (the
transmitted bulk data encodes the channel number). These per-device
resources are allocated and submitted by the first opened channel.
During this allocation, the resources are either released immediately
in case of a failure or the URBs are anchored. All anchored URBs are
finally killed with gs_usb_disconnect().
Currently, gs_can_open() returns with an error if the allocation of a
URB or a buffer fails. However, if usb_submit_urb() fails, the driver
continues with the URBs submitted so far, even if no URBs were
successfully submitted.
Treat every error as fatal and free all allocated resources
immediately.
Switch to goto-style error handling, to prepare the driver for more
per-device resource allocation.

The KSZ8795 driver code was modified to use on KSZ8863/73, which has
different register definitions. Some of the new KSZ8795 register
information are wrong compared to previous code.
KSZ8795 also behaves differently in that the STATIC_MAC_TABLE_USE_FID
and STATIC_MAC_TABLE_FID bits are off by 1 when doing MAC table reading
than writing. To compensate that a special code was added to shift the
register value by 1 before applying those bits. This is wrong when the
code is running on KSZ8863, so this special code is only executed when
KSZ8795 is detected.

Since commit 6624e780a5 ("ice: split ice_vsi_setup into smaller
functions") ice_vsi_release does things twice. There is unregister
netdev which is unregistered in ice_deinit_eth also.
It also unregisters the devlink_port twice which is also unregistered
in ice_deinit_eth(). This double deregistration is hidden because
devl_port_unregister ignores the return value of xa_erase.

Move the call to of_get_ethdev_address to mtk_add_mac which is part of
the probe function and can hence itself return -EPROBE_DEFER should
of_get_ethdev_address return -EPROBE_DEFER. This allows us to entirely
get rid of the mtk_init function.
The problem of of_get_ethdev_address returning -EPROBE_DEFER surfaced
in situations in which the NVMEM provider holding the MAC address has
not yet be loaded at the time mtk_eth_soc is initially probed. In this
case probing of mtk_eth_soc should be deferred instead of falling back
to use a random MAC address, so once the NVMEM provider becomes
available probing can be repeated.

CPSW ALE has 75 bit ALE entries which are stored within three 32 bit words.
The cpsw_ale_get_field() and cpsw_ale_set_field() functions assume that the

guaranteed to be the case and it is possible for ALE field entries to span
across up to two words at the most.
Fix the methods to handle getting/setting fields spanning up to two words.

The at9331 is only able to read or write a single register at once. The
driver has a custom regmap bus and chooses to tell the regmap core about
this by reporting the maximum transfer sizes rather than the explicit
flags that exist at the regmap level. Since there are a number of
problems with the raw transfer limits and the regmap level flags are
better integrated anyway convert the driver to use the flags.

I get sporadic timeouts from the driver when using the
MV88E6352. Reading the status again after the loop fixes the
problem: the operation is successful but goes undetected.
Some added prints show things like this:
[ 58.356209] mv88e6085 mdio_mux-0.1:00: Timeout while waiting
for switch, addr 1b reg 0b, mask 8000, val 0000, data c000
[ 58.367487] mv88e6085 mdio_mux-0.1:00: Timeout waiting for
ATU op 4000, fid 0001
(...)
[ 61.826293] mv88e6085 mdio_mux-0.1:00: Timeout while waiting
for switch, addr 1c reg 18, mask 8000, val 0000, data 9860
[ 61.837560] mv88e6085 mdio_mux-0.1:00: Timeout waiting
for PHY command 1860 to complete
The reason is probably not the commands: I think those are
mostly fine with the 50+50ms timeout, but the problem
appears when OpenWrt brings up several interfaces in
parallel on a system with 7 populated ports: if one of
them take more than 50 ms and waits one or more of the
others can get stuck on the mutex for the switch and then
this can easily multiply.
As we sleep and wait, the function loop needs a final
check after exiting the loop if we were successful.

- Fix some missing-prototype warnings
- Fix user events struct args (did not include size of struct)
When creating a user event, the "struct" keyword is to denote

failed to handle this case.
- Add selftest to struct sizes for user events
- Fix sample code for direct trampolines.
The sample code for direct trampolines attached to handle_mm_fault().
But the prototype changed and the direct trampoline sample code

Due to backward compatibility, the structure used to save stack traces
in the kernel had a fixed size of 8. This structure is exported to
user space via the tracing format file. A change was made to allow
more than 8 functions to be recorded, and user space now uses the
size field to know how many functions are actually in the stack.
But the structure still has size of 8 (even though it points into
the ring buffer that has the required amount allocated to hold a
full stack. This was fine until the fortifier noticed that the
memcpy(&entry->caller, stack, size) was greater than the 8 functions
and would complain at runtime about it. Hide this by using a pointer
to the stack location on the ring buffer instead of using the address
of the entry structure caller field.
- Fix a deadloop in reading trace_pipe that was caused by a mismatch
between ring_buffer_empty() returning false which then asked to
read the data, but the read code uses rb_num_of_entries() that
returned zero, and causing a infinite "retry".

ftrace functions, where this can happen if the linker inserts a bunch of
"NULL" entries, causing the accounting of how many pages needed

and SH4") causes several boards to hang during boot due to incorrect
IRQ numbers.
Geert Uytterhoeven has contributed patches that handle the virq offset
in the IRQ code for the dreamcast, highlander and r2d boards while
Artur Rojek has contributed a patch which handles the virq offset for
the hd64461 companion chip"
