The bluetooth spec states that automatically flushable packets may not be sent to a LE-only controller. The code already supports non-automatically-flushable packets, but uses a bit in the controller feature field to determine whether to use them. That bit is always zero for LE-only devices, so we need to check for the LE-only case explicitly. --- net/bluetooth/l2cap_core.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/net/bluetooth/l2cap_core.c b/net/bluetooth/l2cap_core.c index 4af3821..29d9b9c 100644 --- a/net/bluetooth/l2cap_core.c +++ b/net/bluetooth/l2cap_core.c @@ -764,7 +764,7 @@ static void l2cap_send_cmd(struct l2cap_conn *conn, u8 ident, u8 code, u16 len, if (!skb) return; - if (lmp_no_flush_capable(conn->hcon->hdev)) + if (lmp_no_flush_capable(conn->hcon->hdev) || !lmp_bredr_capable(conn->hcon->hdev)) flags = ACL_START_NO_FLUSH; else flags = ACL_START; @@ -798,8 +798,9 @@ static void l2cap_do_send(struct l2cap_chan *chan, struct sk_buff *skb) return; } - if (!test_bit(FLAG_FLUSHABLE, &chan->flags) && - lmp_no_flush_capable(hcon->hdev)) + if (!lmp_bredr_capable(hcon->hdev) || + (!test_bit(FLAG_FLUSHABLE, &chan->flags) && + lmp_no_flush_capable(hcon->hdev))) flags = ACL_START_NO_FLUSH; else flags = ACL_START; -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
