This reverts commit 1b479fb80160 ("drivers/net/wan/hdlc_fr: Fix a double free in pvc_xmit"). 1. This commit is incorrect. "__skb_pad" will NOT free the skb on failure when its "free_on_error" parameter is "false". 2. This commit claims to fix my commit. But it didn't CC me??

2021-04-05net: x25: Queue received packets in the drivers instead of per-CPU queuesXie He2-8/+71
X.25 Layer 3 (the Packet Layer) expects layer 2 to provide a reliable datalink service such that no packets are reordered or dropped. And X.25 Layer 2 (the LAPB layer) is indeed designed to provide such service. However, this reliability is not preserved when a driver calls "netif_rx" to deliver the received packets to layer 3, because "netif_rx" will put the packets into per-CPU queues before they are delivered to layer 3. If there are multiple CPUs, the order of the packets may not be preserved. The per-CPU queues may also drop packets if there are too many. Therefore, we should not call "netif_rx" to let it queue the packets. Instead, we should use our own queue that won't reorder or drop packets. This patch changes all X.25 drivers to use their own queues instead of calling "netif_rx". The patch also documents this requirement in the "x25-iface" documentation.

2021-03-29drivers/net/wan/hdlc_fr: Fix a double free in pvc_xmitLv Yunlong1-2/+3
In pvc_xmit, if __skb_pad(skb, pad, false) failed, it will free the skb in the first time and goto drop. But the same skb is freed by kfree_skb(skb) in the second time in drop. Maintaining the original function unchanged, my patch adds a new label out to avoid the double free if __skb_pad() failed.
