The tls ulp overrides sk->prot with a new tls specific proto structs.
The tls specific structs were previously based on the ipv4 specific
tcp_prot sturct.
As a result, attaching the tls ulp to an ipv6 tcp socket replaced
some ipv6 callback with the ipv4 equivalents.
This patch adds ipv6 tls proto structs and uses them when
attached to ipv6 sockets.
Changed since v3:
- Removed the use of tcpv6_prot and the dependency on the IPv6 module.
- Should fix the issue triggered by CVE-2018-5703
Changed since v2:
- Dropped patch to fix IPv6_ADDRFORM setsockopt
There was some disagreement about the correct way of fixinig it,
and this series does not depend on it.
Changes since v1:
- TLS now dependes on IPv6
This fixes complication issues when TLS is built-in and IPv6 is a module.
The downside should be small as it is unlikely that there are kernel TLS
users who can't afford to include IPv6 in thier kernel.
- tls_init now checks sk->sk_prot directly
This is somewhat safer then checking indirectly through sk->sk_family

tls: Use correct sk->sk_prot for IPv6
