When sending a broadcast while at least on of the connected stations is sleeping, it gets queued and send after a DTIM beacon is sent. If the packet was to be sent on a vlan interface, the vif used for dequeing from the per-bss queue does not hold the per-vlan sdata. The correct sdata is required to use the correct per-vlan broadcast/multicast key. This patch fixes this by restoring the per-vlan sdata using the skb->dev entry. --- net/mac80211/tx.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/net/mac80211/tx.c b/net/mac80211/tx.c index 2ef0e19..93681f5 100644 --- a/net/mac80211/tx.c +++ b/net/mac80211/tx.c @@ -2770,7 +2770,8 @@ ieee80211_get_buffered_bc(struct ieee80211_hw *hw, cpu_to_le16(IEEE80211_FCTL_MOREDATA); } - if (!ieee80211_tx_prepare(sdata, &tx, skb)) + struct ieee80211_sub_if_data *frame_sdata = IEEE80211_DEV_TO_SUB_IF(skb->dev); + if (!ieee80211_tx_prepare(frame_sdata, &tx, skb)) break; dev_kfree_skb_any(skb); } -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
