Jia-Ju Bai 8b2c13b2e5 rtlwifi: rtl8723ae: avoid accessing the data mapped to streaming DMA ... In rtl8723e_tx_fill_cmddesc(), skb->data is mapped to streaming DMA on line 531: dma_addr_t mapping = dma_map_single(..., skb->data, ...); On line 534, skb->data is assigned to hdr after cast: struct ieee80211_hdr *hdr = (struct ieee80211_hdr *)(skb->data); Then hdr->frame_control is accessed on line 535: __le16 fc = hdr->frame_control; This DMA access may cause data inconsistency between CPU and hardwre. To fix this bug, hdr->frame_control is accessed before the DMA mapping.
