In both cases, the code is very similar to the existing IPv4 encapsulation implementation. The core espintcp code is almost entirely version-independent. v2: rebase on top of ipsec-next/master v3: really rebase this time v4: fix build warning when !_HAVE_ARCH_IPV6_CSUM Sabrina Dubroca (2): xfrm: add support for UDPv6 encapsulation of ESP xfrm: add IPv6 support for espintcp include/net/ipv6_stubs.h | 5 + include/net/xfrm.h | 5 + net/ipv4/Kconfig | 1 + net/ipv4/udp.c | 10 +- net/ipv6/Kconfig | 12 ++ net/ipv6/af_inet6.c | 5 + net/ipv6/ah6.c | 1 + net/ipv6/esp6.c | 414 +++++++++++++++++++++++++++++++++++--- net/ipv6/esp6_offload.c | 7 +- net/ipv6/ip6_vti.c | 18 +- net/ipv6/ipcomp6.c | 1 + net/ipv6/xfrm6_input.c | 106 +++++++++- net/ipv6/xfrm6_protocol.c | 48 +++++ net/xfrm/Kconfig | 3 + net/xfrm/Makefile | 2 +- net/xfrm/espintcp.c | 56 +++++- net/xfrm/xfrm_interface.c | 3 + 17 files changed, 647 insertions(+), 50 deletions(-)
