Wang Shanker 018f825858 net: l2tp: fix reversed udp6 checksum flags ... This patch fixes a bug which causes the behavior of whether to ignore udp6 checksum of udp6 encapsulated l2tp tunnel contrary to what userspace program requests. When the flag `L2TP_ATTR_UDP_ZERO_CSUM6_RX` is set by userspace, it is expected that udp6 checksums of received packets of the l2tp tunnel to create should be ignored. In `l2tp_netlink.c`: `l2tp_nl_cmd_tunnel_create()`, `cfg.udp6_zero_rx_checksums` is set according to the flag, and then passed to `l2tp_core.c`: `l2tp_tunnel_create()` and then `l2tp_tunnel_sock_create()`. In `l2tp_tunnel_sock_create()`, `udp_conf.use_udp6_rx_checksums` is set the same to `cfg.udp6_zero_rx_checksums`. However, if we want the checksum to be ignored, `udp_conf.use_udp6_rx_checksums` should be set to `false`, i.e. be set to the contrary. Similarly, the same should be done to `udp_conf.use_udp6_tx_checksums`. Signed-off-by: Miao Wang <shankerwangmiao@gmail.com> Acked-by: James Chapman <jchapman@katalix.com> Signed-off-by: David S.
