2020-09-21net/mlx5e: Fix using wrong stats_grps in mlx5e_update_ndo_stats()Alaa Hleihel6-15/+17
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.

2020-09-21net/mlx5e: Fix multicast counter not up-to-date in "ip -s"Ron Diskin4-7/+12
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".

2020-09-21net/mlx5e: Use synchronize_rcu to sync with NAPIMaxim Mikityanskiy5-36/+22
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.

2020-09-21net/mlx5e: Use RCU to protect rq->xdp_progMaxim Mikityanskiy3-30/+27
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.

2020-09-21net/mlx5: Fix FTE cleanupMaor Gottlieb1-4/+4
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.

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.

2020-09-21wcn36xx: Add wcn36xx_smd_set_sta_default_vht_params()Bryan O'Donoghue1-0/+18
This commit adds support for setting default VHT parameters, which are exposed by the extended version 1 STA parameter type. Signed-off-by: Bryan O'Donoghue <[email protected]> Signed-off-by: Kalle Valo <[email protected]> Link: https://lore.kernel.org/r/[email protected]

2020-09-21wcn36xx: Use V1 data structure to store supported ratesBryan O'Donoghue2-3/+4
This patch converts the internal data structure used to store data-rates from version 0 to version 1. This allows us to extend out the internal storage to represent VHT parameters. Using the extended version 1 data-structure allows us to avoid a whole raft of version 1 specific fixup functions.

2020-09-21wcn36xx: Add VHT fields to parameter data structuresBryan O'Donoghue2-1/+15
In order to pass VHT parameters to wcn3680 we need to use a super-set of the V1 data-structures with additional VHT parameters tacked on. 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.

2020-09-21ath11k: Remove rproc references from common core layerGovind Singh4-37/+44
IPQ8074 HW uses rproc with AHB as underlying hif layer. Move rproc references from common core layer to target hif layer. Remove IS_ENABLED check for CONFIG_REMOTEPROC as it's not required anymore. No functional changes. Compile tested only. Signed-off-by: Govind Singh <[email protected]> Signed-off-by: Kalle Valo <[email protected]> Link: https://lore.kernel.org/r/[email protected]
2020-09-21ath9k: hif_usb: fix race condition between usb_get_urb() and ↵Brooke Basile1-0/+19
usb_kill_anchored_urbs() 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().
