This causes beacons/tx to fail if the control channel is on a non-DFS channel. Fix this by calling cfg80211_reg_can_beacon to determine the DFS status of all affected channels Signed-off-by: Felix Fietkau --- drivers/net/wireless/mediatek/mt76/mac80211.c | 2 +- drivers/net/wireless/mediatek/mt76/mt7615/mcu.c | 8 +++++--- drivers/net/wireless/mediatek/mt76/mt7915/mcu.c | 8 +++++--- drivers/net/wireless/mediatek/mt76/mt7921/mcu.c | 8 +++++--- 4 files changed, 16 insertions(+), 10 deletions(-) diff --git a/drivers/net/wireless/mediatek/mt76/mac80211.c b/drivers/net/wireless/mediatek/mt76/mac80211.c index 9796419c99e1..372b94a665ec 100644 --- a/drivers/net/wireless/mediatek/mt76/mac80211.c +++ b/drivers/net/wireless/mediatek/mt76/mac80211.c @@ -1658,7 +1658,7 @@ enum mt76_dfs_state mt76_phy_dfs_state(struct mt76_phy *phy) return MT_DFS_STATE_DISABLED; } - if (phy->chandef.chan->dfs_state != NL80211_DFS_AVAILABLE) + if (!cfg80211_reg_can_beacon(hw->wiphy, &phy->chandef, NL80211_IFTYPE_AP)) return MT_DFS_STATE_CAC; return MT_DFS_STATE_ACTIVE; diff --git a/drivers/net/wireless/mediatek/mt76/mt7615/mcu.c b/drivers/net/wireless/mediatek/mt76/mt7615/mcu.c index 120760ea1c89..e98c6076a633 100644 --- a/drivers/net/wireless/mediatek/mt76/mt7615/mcu.c +++ b/drivers/net/wireless/mediatek/mt76/mt7615/mcu.c @@ -2151,10 +2151,12 @@ int mt7615_mcu_set_chan_info(struct mt7615_phy *phy, int cmd) .center_chan2 = ieee80211_frequency_to_channel(freq2), }; - if (phy->mt76->hw->conf.flags & IEEE80211_CONF_OFFCHANNEL) + if (cmd == MCU_EXT_CMD(SET_RX_PATH)) + req.switch_reason = CH_SWITCH_NORMAL; + else if (phy->mt76->hw->conf.flags & IEEE80211_CONF_OFFCHANNEL) req.switch_reason = CH_SWITCH_SCAN_BYPASS_DPD; - else if ((chandef->chan->flags & IEEE80211_CHAN_RADAR) && - chandef->chan->dfs_state != NL80211_DFS_AVAILABLE) + else if (!cfg80211_reg_can_beacon(phy->mt76->hw->wiphy, chandef, + NL80211_IFTYPE_AP)) req.switch_reason = CH_SWITCH_DFS; else req.switch_reason = CH_SWITCH_NORMAL; diff --git a/drivers/net/wireless/mediatek/mt76/mt7915/mcu.c b/drivers/net/wireless/mediatek/mt76/mt7915/mcu.c index 8c014299daa1..119f9358162f 100644 --- a/drivers/net/wireless/mediatek/mt76/mt7915/mcu.c +++ b/drivers/net/wireless/mediatek/mt76/mt7915/mcu.c @@ -2811,10 +2811,12 @@ int mt7915_mcu_set_chan_info(struct mt7915_phy *phy, int cmd) } #endif - if (phy->mt76->hw->conf.flags & IEEE80211_CONF_OFFCHANNEL) + if (cmd == MCU_EXT_CMD(SET_RX_PATH)) + req.switch_reason = CH_SWITCH_NORMAL; + else if (phy->mt76->hw->conf.flags & IEEE80211_CONF_OFFCHANNEL) req.switch_reason = CH_SWITCH_SCAN_BYPASS_DPD; - else if (phy->mt76->hw->conf.radar_enabled && - chandef->chan->dfs_state != NL80211_DFS_AVAILABLE) + else if (!cfg80211_reg_can_beacon(phy->mt76->hw->wiphy, chandef, + NL80211_IFTYPE_AP)) req.switch_reason = CH_SWITCH_DFS; else req.switch_reason = CH_SWITCH_NORMAL; diff --git a/drivers/net/wireless/mediatek/mt76/mt7921/mcu.c b/drivers/net/wireless/mediatek/mt76/mt7921/mcu.c index 33a836825cca..e7adcba7a8bf 100644 --- a/drivers/net/wireless/mediatek/mt76/mt7921/mcu.c +++ b/drivers/net/wireless/mediatek/mt76/mt7921/mcu.c @@ -863,10 +863,12 @@ int mt7921_mcu_set_chan_info(struct mt7921_phy *phy, int cmd) else req.channel_band = chandef->chan->band; - if (dev->mt76.hw->conf.flags & IEEE80211_CONF_OFFCHANNEL) + if (cmd == MCU_EXT_CMD(SET_RX_PATH)) + req.switch_reason = CH_SWITCH_NORMAL; + else if (dev->mt76.hw->conf.flags & IEEE80211_CONF_OFFCHANNEL) req.switch_reason = CH_SWITCH_SCAN_BYPASS_DPD; - else if ((chandef->chan->flags & IEEE80211_CHAN_RADAR) && - chandef->chan->dfs_state != NL80211_DFS_AVAILABLE) + else if (!cfg80211_reg_can_beacon(dev->mt76.hw->wiphy, chandef, + NL80211_IFTYPE_AP)) req.switch_reason = CH_SWITCH_DFS; else req.switch_reason = CH_SWITCH_NORMAL;
