If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit c18083195eba3ddecdbd744d1069f7a296ea8231 Author: Ajay Singh <ajay.kathat@xxxxxxxxxxxxx> Date: Mon Jan 15 15:56:34 2024 +0100 wifi: wilc1000: fix multi-vif management when deleting a vif [ Upstream commit 12cfc9c8d3faf887a202c89bc312202445fca7e8 ] Adding then removing a second vif currently makes the first vif not working anymore. 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 <ajay.kathat@xxxxxxxxxxxxx> Co-developed-by: Alexis Lothoré <alexis.lothore@xxxxxxxxxxx> Signed-off-by: Alexis Lothoré <alexis.lothore@xxxxxxxxxxx> Signed-off-by: Kalle Valo <kvalo@xxxxxxxxxx> Link: https://msgid.link/20240115-wilc_1000_fixes-v1-5-54d29463a738@xxxxxxxxxxx Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> diff --git a/drivers/net/wireless/microchip/wilc1000/cfg80211.c b/drivers/net/wireless/microchip/wilc1000/cfg80211.c index 2f75dc4b47975..6f3245a43aef1 100644 --- a/drivers/net/wireless/microchip/wilc1000/cfg80211.c +++ b/drivers/net/wireless/microchip/wilc1000/cfg80211.c @@ -1615,7 +1615,6 @@ 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--;
