2019-04-01tcp: fix tcp_inet6_sk() for 32bit kernelsEric Dumazet1-2/+3
It turns out that struct ipv6_pinfo is not located as we think. inet6_sk_generic() and tcp_inet6_sk() disagree on 32bit kernels by 4-bytes, because struct tcp_sock has 8-bytes alignment, but ipv6_pinfo size is not a multiple of 8. sizeof(struct ipv6_pinfo): 116 (not padded to 8) I actually first coded tcp_inet6_sk() as this patch does, but thought that "container_of(tcp_sk(sk), struct tcp6_sock, tcp)" was cleaner. As Julian told me : Nobody should use tcp6_sock.inet6 directly, it should be accessed via tcp_inet6_sk() or inet6_sk(). This happened when we added the first u64 field in struct tcp_sock.

fib6_ignore_linkdown takes a fib6_info but only looks at the net_device and its IPv6 config. Change it to take a net_device over a fib6_info as its input argument. In addition, move it to a header file to make the check inline and usable later with IPv4 code without going through the ipv6 stub, and rename to ip6_ignore_linkdown since it is only checking the setting based on the ipv6 struct on a device.

2019-03-29ipv6: Move gateway checks to a fib6_nh settingDavid Ahern7-30/+41
The gateway setting is not per fib6_info entry but per-fib6_nh. Add a new fib_nh_has_gw flag to fib6_nh and convert references to RTF_GATEWAY to the new flag. For IPv6 address the flag is cheaper than checking that nh_gw is non-0 like IPv4 does. While this increases fib6_nh by 8-bytes, the effective allocation size of a fib6_info is unchanged. The 8 bytes is recovered later with a fib_nh_common change. Signed-off-by: David Ahern <dsahern@gmail.com> Reviewed-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S.
