[PATCH 1/2] net: tls: add compat for get/setsockopt

If compat_{s,g}etsockopt for TLS are not implemented, the TLS layer will never be called on a system where CONFIG_COMPAT is enabled and userspace is 32bit. Implement both to support CONFIG_COMPAT. Signed-off-by: Rouven Czerwinski --- net/tls/tls_main.c | 28 1 file
