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. 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 Ilya Lesokhin (3): ipv6: Prevent unexpected sk->sk_prot changes net: Export tcpv6_prot tls: Use correct sk->sk_prot for IPV6 net/ipv6/ipv6_sockglue.c | 12 ++++++++++++ net/ipv6/tcp_ipv6.c | 1 + net/tls/Kconfig | 1 + net/tls/tls_main.c | 50 ++++++++++++++++++++++++++++++++++++------------ 4 files changed, 52 insertions(+), 12 deletions(-) -- 1.8.3.1
