2018-07-07ip: unconditionally set cork gso_sizeWillem de Bruijn
Now that ipc(6)->gso_size is correctly initialized in all callers of ip(6)_setup_cork, it is safe to unconditionally pass it to the cork.

2018-07-07ip: remove tx_flags from ipcm_cookie and use same logic for v4 and v6Willem de Bruijn
skb_shinfo(skb)->tx_flags is derived from sk->sk_tsflags, possibly after modification by __sock_cmsg_send, by calling sock_tx_timestamp. The IPv4 and IPv6 paths do this conversion differently. In IPv4, the individual protocols that support tx timestamps call this function and store the result in ipc.tx_flags. In IPv6, sock_tx_timestamp is called in __ip6_append_data. There is no need to store both tx_flags and ts_flags in the cookie as one is derived from the other. Convert when setting up the cork and remove the redundant field. This is similar to IPv6, only have the conversion happen only once per datagram, in ip(6)_setup_cork. Also change __ip6_append_data to match __ip_append_data. Only update tskey if timestamping is enabled with OPT_ID. The SOCK_.. test is redundant: only valid protocols can have non-zero cork->tx_flags. After this change the IPv4 and IPv6 logic is the same.

2018-07-07ipv6: fold sockcm_cookie into ipcm6_cookieWillem de Bruijn
ipcm_cookie includes sockcm_cookie. Do the same for ipcm6_cookie. This reduces the number of arguments that need to be passed around, applies ipcm6_init to all cookie fields at once and reduces code differentiation between ipv4 and ipv6.

2018-07-06net: ipv4: fix list processing on L3 slave devicesEdward Cree
If we have an L3 master device, l3mdev_ip_rcv() will steal the skb, but we were returning NET_RX_SUCCESS from ip_rcv_finish_core() which meant that ip_list_rcv_finish() would keep it on the list. Instead let's move the l3mdev_ip_rcv() call into the caller, so that our response to a steal can be different in the single packet path (return NET_RX_SUCCESS) and the list path (forget this packet and continue).
