| H A D | xfrm_device.c | 94579ac3 Mon Jun 01 16:39:37 CDT 2020 Huy Nguyen <huyn@mellanox.com> xfrm: Fix double ESP trailer insertion in IPsec crypto offload.
During IPsec performance testing, we see bad ICMP checksum. The error packet
has duplicated ESP trailer due to double validate_xmit_xfrm calls. The first call
is from ip_output, but the packet cannot be sent because
netif_xmit_frozen_or_stopped is true and the packet gets dev_requeue_skb. The second
call is from NET_TX softirq. However after the first call, the packet already
has the ESP trailer.
Fix by marking the skb with XFRM_XMIT bit after the packet is handled by
validate_xmit_xfrm to avoid duplicate ESP trailer insertion.
Fixes: f6e27114a60a ("net: Add a xfrm validate function to validate_xmit_skb")
