From d515f6b6cde357bf480d32a7387f07ea40e85e52 Mon Sep 17 00:00:00 2001 From: Bob Cantor Date: Fri, 25 Jun 2021 04:07:34 +1000 Subject: mac80211: always call wireless_set_data (FS#3784) When wifi is turned off, drv_mac80211_teardown sometimes fails (silently) because the device to be torn down is not defined. This situation arises if drv_mac80211_setup was called twice when wifi was turned on. This commit ensures that the device to be torn down is always defined in drv_mac80211_teardown. Steps to reproduce: 1) Use /sbin/wifi to turn on wifi. uci set wireless.@wifi-iface[0].disabled=0 uci set wireless.@wifi-device[0].disabled=0 uci commit wifi 2) Use /sbin/wifi to turn off wifi. uci set wireless.@wifi-device[0].disabled=1 uci commit wifi 3) Observe that wifi is still up. branches affected: trunk, 21.02 Signed-off-by: Bob Cantor --- package/kernel/mac80211/files/lib/netifd/wireless/mac80211.sh | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) (limited to 'package/kernel') diff --git a/package/kernel/mac80211/files/lib/netifd/wireless/mac80211.sh b/package/kernel/mac80211/files/lib/netifd/wireless/mac80211.sh index c7437d5a96..ffb3662d04 100644 --- a/package/kernel/mac80211/files/lib/netifd/wireless/mac80211.sh +++ b/package/kernel/mac80211/files/lib/netifd/wireless/mac80211.sh @@ -1021,10 +1021,8 @@ drv_mac80211_setup() { return 1 } - [ -z "$(uci -q -P /var/state show wireless._${phy})" ] && { - uci -q -P /var/state set wireless._${phy}=phy - wireless_set_data phy="$phy" - } + wireless_set_data phy="$phy" + [ -z "$(uci -q -P /var/state show wireless._${phy})" ] && uci -q -P /var/state set wireless._${phy}=phy OLDAPLIST=$(uci -q -P /var/state get wireless._${phy}.aplist) OLDSPLIST=$(uci -q -P /var/state get wireless._${phy}.splist) -- cgit v1.2.3
