However, while the driver needs only one workqueue, the wilc_netdev_ifc_init is called each time we add an interface over a phy, which in turns overwrite the workqueue with a new one. This can be observed with the following commands: for i in $(seq 0 10) do iw phy phy0 interface add wlan1 type managed iw dev wlan1 del done ps -eo pid,comm|grep wlan 39 kworker/R-wlan0 98 kworker/R-wlan1 102 kworker/R-wlan1 105 kworker/R-wlan1 108 kworker/R-wlan1 111 kworker/R-wlan1 114 kworker/R-wlan1 117 kworker/R-wlan1 120 kworker/R-wlan1 123 kworker/R-wlan1 126 kworker/R-wlan1 129 kworker/R-wlan1 Fix this leakage by putting back hif_workqueue allocation in wilc_cfg80211_init. Regarding the workqueue name, it is indeed relevant to set it lowercase, however it is not attached to a specific netdev, so enforcing netdev name in the name is not so relevant. Still, enrich the name with the wiphy name to make it clear which phy is using the workqueue.

This is visible for example when we have a first interface connected to some access point: - create a wpa_supplicant.conf with some AP credentials - wpa_supplicant -Dnl80211 -c /etc/wpa_supplicant.conf -i wlan0 - dhclient wlan0 - iw phy phy0 interface add wlan1 type managed - iw dev wlan1 del wlan0 does not manage properly traffic anymore (eg: ping not working) This is due to vif mode being incorrectly reconfigured with some default values in del_virtual_intf, affecting by default first vif. Prevent first vif from being affected on second vif removal by removing vif mode change command in del_virtual_intf Fixes: 9bc061e88054 ("staging: wilc1000: added support to dynamically add/remove interfaces") Signed-off-by: Ajay Singh Co-developed-by: Alexis Lothoré Signed-off-by: Alexis Lothoré --- This patch has been initiated by Ajay, and I reworked it a bit/split it. I could have just fixed the parameters passed to wilc_set_operation_mode, but I observed that even calling wilc_set_operation_mode seems faulty in del_virtual_intf: for example the thread in charge of sending commands to the chip is possibly not running (because interface is not up). Also, the vif mode is only configured in change_virtual_intf and not in add_virtual_intf, which tends to validate the removal from del_virtual_intf. --- drivers/net/wireless/microchip/wilc1000/cfg80211.c | 1 - 1 file changed, 1 deletion(-) diff --git a/drivers/net/wireless/microchip/wilc1000/cfg80211.c b/drivers/net/wireless/microchip/wilc1000/cfg80211.c index 2d0474e6404e..f03fd15c0c97 100644 --- a/drivers/net/wireless/microchip/wilc1000/cfg80211.c +++ b/drivers/net/wireless/microchip/wilc1000/cfg80211.c @@ -1609,7 +1609,6 @@ static int del_virtual_intf(struct wiphy *wiphy, struct wireless_dev *wdev) cfg80211_unregister_netdevice(vif->ndev); vif->monitor_flag = 0; - wilc_set_operation_mode(vif, 0, 0, 0); mutex_lock(&wl->vif_mutex); list_del_rcu(&vif->list); wl->vif_num--;
