I finaly could test it (I have a very slow machine while traveling, and compiling the thing took a *lot* of time) Now back to family affairs ;) -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[PATCH] ipv6: Fix inet6_csk_bind_conflict() Commit fda48a0d7a84 (tcp: bind() fix when many ports are bound) introduced a bug on IPV6 part. We should not call ipv6_addr_any(inet6_rcv_saddr(sk2)) but ipv6_addr_any(inet6_rcv_saddr(sk)) because sk2 can be IPV4, while sk is IPV6. Reported-by: Michael S.
