From 128b75bf5cf93bca71da740d3cb623c1febb6bf6 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 31 Jan 2019 21:01:24 +0100 Subject: [PATCH] mt76: fix software encryption issues Software encrypted packets can be passed not just through the drv_tx callback, but also through the intermediate tx queue. In order to deal with that, move the override to mt76x02_mac_write_txwi and also take care of filling in the per-packet rate information Signed-off-by: Felix Fietkau --- drivers/net/wireless/mediatek/mt76/mt76x02_mac.c | 7 +++++++ drivers/net/wireless/mediatek/mt76/mt76x02_txrx.c | 9 +-------- 2 files changed, 8 insertions(+), 8 deletions(-) diff --git a/drivers/net/wireless/mediatek/mt76/mt76x02_mac.c b/drivers/net/wireless/mediatek/mt76/mt76x02_mac.c index 2dc80ea26752..6bd7f87644a4 100644 --- a/drivers/net/wireless/mediatek/mt76/mt76x02_mac.c +++ b/drivers/net/wireless/mediatek/mt76/mt76x02_mac.c @@ -291,6 +291,13 @@ void mt76x02_mac_write_txwi(struct mt76x02_dev *dev, struct mt76x02_txwi *txwi, memset(txwi, 0, sizeof(*txwi)); + if (!info->control.hw_key && wcid && wcid->hw_key_idx != 0xff && + ieee80211_has_protected(hdr->frame_control)) { + wcid = NULL; + ieee80211_get_tx_rates(info->control.vif, sta, skb, + info->control.rates, 1); + } + if (wcid) txwi->wcid = wcid->idx; else diff --git a/drivers/net/wireless/mediatek/mt76/mt76x02_txrx.c b/drivers/net/wireless/mediatek/mt76/mt76x02_txrx.c index 7861a832940b..94f47248c59f 100644 --- a/drivers/net/wireless/mediatek/mt76/mt76x02_txrx.c +++ b/drivers/net/wireless/mediatek/mt76/mt76x02_txrx.c @@ -22,7 +22,6 @@ void mt76x02_tx(struct ieee80211_hw *hw, struct ieee80211_tx_control *control, struct sk_buff *skb) { - struct ieee80211_hdr *hdr = (struct ieee80211_hdr *) skb->data; struct ieee80211_tx_info *info = IEEE80211_SKB_CB(skb); struct mt76x02_dev *dev = hw->priv; struct ieee80211_vif *vif = info->control.vif; @@ -33,13 +32,7 @@ void mt76x02_tx(struct ieee80211_hw *hw, struct ieee80211_tx_control *control, msta = (struct mt76x02_sta *)control->sta->drv_priv; wcid = &msta->wcid; - /* sw encrypted frames */ - if (!info->control.hw_key && wcid->hw_key_idx != 0xff && - ieee80211_has_protected(hdr->frame_control)) - control->sta = NULL; - } - - if (vif && !control->sta) { + } else if (vif) { struct mt76x02_vif *mvif; mvif = (struct mt76x02_vif *)vif->drv_priv; -- 2.30.2
