b521105b68 net/mlx5e: Fix using wrong stats_grps in mlx5e_update_ndo_stats()
The cited commit started to reuse function mlx5e_update_ndo_stats() for
the representors as well.
However, the function is hard-coded to work on mlx5e_nic_stats_grps only.
Due to this issue, the representors statistics were not updated in the
output of "ip -s".

Fix it to work with the correct group by extracting it from the caller's
profile.

Also, while at it and since this function became generic, move it to
en_stats.c and rename it accordingly.

47c97e6b10 net/mlx5e: Fix multicast counter not up-to-date in "ip -s"
Currently the FW does not generate events for counters other than error
counters. Unlike ".get_ethtool_stats", ".ndo_get_stats64" (which ip -s
uses) might run in atomic context, while the FW interface is non atomic.
Thus, 'ip' is not allowed to issue FW commands, so it will only display
cached counters in the driver.

Add a SW counter (mcast_packets) in the driver to count rx multicast
packets. The counter also counts broadcast packets, as we consider it a
special case of multicast.
Use the counter value when calling "ip -s"/"ifconfig".

6cec0229ab net/mlx5e: Enable adding peer miss rules only if merged eswitch is supported
The cited commit creates peer miss group during switchdev mode

LAG mode. This is done regardless of FW support of such groups which
could cause rules setups failure later on.

Fix by adding FW capability check before creating peer groups/rule.

9c25a22dfb net/mlx5e: Use synchronize_rcu to sync with NAPI
As described in the previous commit, napi_synchronize doesn't quite fit
the purpose when we just need to wait until the currently running NAPI
quits. Its implementation waits until NAPI is not running by polling and
waiting for 1ms in between. In cases where we need to deactivate one
queue (e.g., recovery flows) or where we deactivate them one-by-one
(deactivate channel flow), we may get stuck in napi_synchronize forever
if other queues keep NAPI active, causing a soft lockup. Depending on
kernel configuration (CONFIG_BOOTPARAM_SOFTLOCKUP_PANIC), it may result
in a kernel panic.

To fix the issue, use synchronize_rcu to wait for NAPI to quit, and wrap
the whole NAPI in rcu_read_lock.

fe45386a20 net/mlx5e: Use RCU to protect rq->xdp_prog
Currently, the RQs are temporarily deactivated while hot-replacing the
XDP program, and napi_synchronize is used to make sure rq->xdp_prog is
not in use. However, napi_synchronize is not ideal: instead of waiting
till the end of a NAPI cycle, it polls and waits until NAPI is not
running, sleeping for 1ms between the periodic checks. Under heavy
workloads, this loop will never end, which may even lead to a kernel
panic if the kernel detects the hangup. Such workloads include XSK TX
and possibly also heavy RX (XSK or normal).

The fix is inspired by commit 326fe02d1ed6 ("net/mlx4_en: protect
ring->xdp_prog with rcu_read_lock"). As mlx5e_xdp_handle is already
protected by rcu_read_lock, and bpf_prog_put uses call_rcu to free the
program, there is no need for additional synchronization if proper RCU
functions are used to access the pointer. This patch converts all
accesses to rq->xdp_prog to use RCU functions.

cefc23554f net/mlx5: Fix FTE cleanup
Currently, when an FTE is allocated, its refcount is decreased to 0
with the purpose it will not be a stand alone steering object and every
rule (destination) of the FTE would increase the refcount.
When mlx5_cleanup_fs is called while not all rules were deleted by the
steering users, it hit refcount underflow on the FTE once clean_tree
calls to tree_remove_node after the deleted rules already decreased
the refcount to 0.

FTE is no longer destroyed implicitly when the last rule (destination)
is deleted. mlx5_del_flow_rules avoids it by increasing the refcount on
the FTE and destroy it explicitly after all rules were deleted. So we
can avoid the refcount underflow by making FTE as stand alone object.
In addition need to set del_hw_func to FTE so the HW object will be
destroyed when the FTE is deleted from the cleanup_tree flow.

refcount_t: underflow; use-after-free.

====================
pull-request: can-next 2020-09-21

this is a pull request of 38 patches for net-next.

the first 5 patches are by Colin Ian King, Alexandre Belloni and me and they
fix various spelling mistakes.

The next patch is by me and fixes the indention in the CAN raw protocol
according to the kernel coding style.

Diego Elio Pettenò contributes two patches to fix dead links in CAN's Kconfig.

Masahiro Yamada's patch removes the "WITH Linux-syscall-note" from SPDX tag of
C files.

AThe next 4 patches are by me and target the CAN device infrastructure and add
error propagation and improve the output of various messages to ease driver
development and debugging.

YueHaibing's patch for the c_can driver removes an unused inline function.

Next follows another patch by Colin Ian King, which removes the unneeded
initialization of a variable in the mcba_usb driver.

A patch by me annotates a fallthrough in the mscan driver.

The ti_hecc driver is converted to use devm_platform_ioremap_resource_byname()
in a patch by Dejin Zheng.

Liu Shixin's patch converts the pcan_usb_pro driver to make use of
le32_add_cpu() instead of open coding it.

Wang Hai's patch for the peak_pciefd_main driver removes an unused makro.

Vaibhav Gupta's patch converts the pch_can driver to generic power management.

Stephane Grosjean improves the pcan_usb usb driver by first documenting the
commands sent to the device and by adding support of rxerr/txerr counters.

The next patch is by me and cleans up the Kconfig of the CAN SPI drivers.

The next 6 patches all target the mcp251x driver, they are by Timo Schlüßler,
Andy Shevchenko, Tim Harvey and me. They update the DT bindings documentation,
sort the include files alphabetically, add GPIO support, make use of the
readx_poll_timeout() helper, and add support for half duplex SPI-controllers.

Wolfram Sang contributes a patch to update the contact email address in the
mscan driver, while Zhang Changzhong updates the clock handling.

The next patch is by and updates the rx-offload infrastructure to support
callback less usage.

The last 6 patches add support for the mcp25xxfd CAN SPI driver. First the
dt-bindings are added by Oleksij Rempel, the regmap infrastructure and the main
driver is contributed by me. Kurt Van Dijck adds listen-only support,
Manivannan Sadhasivam adds himself as maintainer, and Thomas Kopp himself as a
reviewer.

d1e11d5f21 wcn36xx: Remove dead code in wcn36xx_smd_config_bss()
wcn36xx_smd_config_bss_v0() and wcn36xx_smd_config_bss_v1() have been
designed to operate in standalone fashion. As a result we can drop the
dead code now present in wcn36xx_smd_config_bss() and happily remove one
kzalloc from the BSS config path as we do so.

In order to pass VHT parameters to wcn3680 we need to use a super-set of

This patch adds the additional fields to the STA and BSS parameter
structures.

Since neither wcn3620 nor wcn3660 support VHT the size of the passed
message is fixed to the previous message length. Subsequent changes will
differentiate between wcn3620/wcn3660 and wcn3680 which does use the larger
message size.

Calls to usb_kill_anchored_urbs() after usb_kill_urb() on multiprocessor
systems create a race condition in which usb_kill_anchored_urbs() deallocates
the URB before the completer callback is called in usb_kill_urb(), resulting
in a use-after-free.
To fix this, add proper lock protection to usb_kill_urb() calls that can
possibly run concurrently with usb_kill_anchored_urbs().
