If xfrm_input() is called with UDP_ENCAP_ESPINUDP, the packet is already processed in UDP layer that removes the UDP header. Therefore, there should be no much difference to treat it as an ESP packet in the XFRM stack. Test: Enabled dir=in IPsec crypto offload, and verified IPv4 UDP-encapsulated ESP packets on both wifi/cellular network Signed-off-by: Mike Yu <yumike@google.com> --- net/xfrm/xfrm_input.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
