Hello Jakub, hello David,
until the mess with yesterdays pull request is sorted out, here's a
pull request with the remaining 3 patches for net/master.
The 1st patch is by me, targets the flexcan driver and fixes a
potential system hang on single core systems under high CAN packet
rate.
The next 2 patches are also by me and target the gs_usb driver. A
potential race condition during the ndo_open callback as well as the
return value if the ethtool identify feature is not supported are
fixed.
regards,
Marc

The following happened on an i.MX25 using flexcan with many packets on
the bus:
The rx-offload queue reached a length more than skb_queue_len_max. In
can_rx_offload_offload_one() the drop variable was set to true which
made the call to .mailbox_read() (here: flexcan_mailbox_read()) to
_always_ return ERR_PTR(-ENOBUFS) and drop the rx'ed CAN frame. So
can_rx_offload_offload_one() returned ERR_PTR(-ENOBUFS), too.
can_rx_offload_irq_offload_fifo() looks as follows:
| while (1) {
| skb = can_rx_offload_offload_one(offload, 0);
| if (IS_ERR(skb))
| continue;
| if (!skb)
| break;
| ...
| }
The flexcan driver wrongly always returns ERR_PTR(-ENOBUFS) if drop is
requested, even if there is no CAN frame pending. As the i.MX25 is a
single core CPU, while the rx-offload processing is active, there is
no thread to process packets from the offload queue. So the queue
doesn't get any shorter and this results is a tight loop.
Instead of always returning ERR_PTR(-ENOBUFS) if drop is requested,
return NULL if no CAN frame is pending.
Changes since v1: https://lore.kernel.org/all/20220810144536.389237-1-u.kleine-koenig@pengutronix.de
- don't break in can_rx_offload_irq_offload_fifo() in case of an error,
return NULL in flexcan_mailbox_read() in case of no pending CAN frame
instead

The dev->can.state is set to CAN_STATE_ERROR_ACTIVE, after the device
has been started. On busy networks the CAN controller might receive
CAN frame between and go into an error state before the dev->can.state
is assigned.
Assign dev->can.state before starting the controller to close the race
window.

Until commit 409c188c57cd ("can: tree-wide: advertise software
timestamping capabilities") the ethtool_ops was only assigned for
devices which support the GS_CAN_FEATURE_IDENTIFY feature. That commit
assigns ethtool_ops unconditionally.
This results on controllers without GS_CAN_FEATURE_IDENTIFY support
for the following ethtool error:
| $ ethtool -p can0 1
| Cannot identify NIC: Broken pipe
Restore the correct error value by checking for
GS_CAN_FEATURE_IDENTIFY in the gs_usb_set_phys_id() function.
| $ ethtool -p can0 1
| Cannot identify NIC: Operation not supported
While there use the variable "netdev" for the "struct net_device"
pointer and "dev" for the "struct gs_can" pointer as in the rest of
the driver.

FYI, we got a small conflict when merging -net in net-next in the MPTCP
tree due to this patch applied in -net:
5440428b3da6 ("can: gs_usb: gs_can_open(): fix race dev->can.state
condition")
and this one from net-next:
45dfa45f52e6 ("can: gs_usb: add RX and TX hardware timestamp support")
The conflict has been resolved on our side[1] and the resolution we
suggest is attached to this email.
Cheers,
Matt

Thanks for the resolution! If you happen to remember perhaps throw
"manual merge" into the subject. That's what I search my inbox for
when merging, it will allow us to be even more lazy :)
