udp_tunnel: Only build ip6_udp_tunnel.c when IPV6 is selected

2014-09-20T02:05:28+00:00

Functions supplied in ip6_udp_tunnel.c are only needed when IPV6 is
selected. When IPV6 is not selected, those functions are stubbed out
in udp_tunnel.h.

udp_tunnel: Seperate ipv6 functions into its own file.

2014-09-19T19:57:15+00:00

Add ip6_udp_tunnel.c for ipv6 UDP tunnel functions to avoid ifdefs
in udp_tunnel.c

xfrm6: Add IPsec protocol multiplexer

2014-03-14T06:28:07+00:00

This patch adds an IPsec protocol multiplexer for ipv6. With
this it is possible to add alternative protocol handlers, as
needed for IPsec virtual tunnel interfaces.

ipv6: Add support for IPsec virtual tunnel interfaces

2013-10-10T10:00:01+00:00

This patch adds IPv6  support for IPsec virtual tunnel interfaces
(vti). IPsec virtual tunnel interfaces provide a routable interface
for IPsec tunnel endpoints.

net: ipv6: Add IPv6 support to the ping socket.

2013-05-26T04:07:49+00:00

This adds the ability to send ICMPv6 echo requests without a
raw socket. The equivalent ability for ICMPv4 was added in
2011.

Instead of having separate code paths for IPv4 and IPv6, make
most of the code in net/ipv4/ping.c dual-stack and only add a
few IPv6-specific bits (like the protocol definition) to a new
net/ipv6/ping.c. Hopefully this will reduce divergence and/or
duplication of bugs in the future.

Caveats:

- Setting options via ancillary data (e.g., using IPV6_PKTINFO
  to specify the outgoing interface) is not yet supported.
- There are no separate security settings for IPv4 and IPv6;
  everything is controlled by /proc/net/ipv4/ping_group_range.
- The proc interface does not yet display IPv6 ping sockets
  properly.

Tested with a patched copy of ping6 and using raw socket calls.
Compiles and works with all of CONFIG_IPV6={n,m,y}.

ipv6: Kill ipv6 dependency of icmpv6_send().

2013-04-29T17:54:36+00:00

Following patch adds icmp-registration module for ipv6.  It allows
ipv6 protocol to register icmp_sender which is used for sending
ipv6 icmp msgs.  This extra layer allows us to kill ipv6 dependency
for sending icmp packets.

This patch also fixes ip_tunnel compilation problem when ip_tunnel
is statically compiled in kernel but ipv6 is module

ipv6: move csum_ipv6_magic() and udp6_csum_init() into static library

2013-01-09T01:56:10+00:00

As suggested by David, udp6_csum_init() is too big to be inlined,
move it to ipv6 static library, net/ipv6/ip6_checksum.c.

And the generic csum_ipv6_magic() too.

ipv6: Fix Makefile offload objects

The following commit breaks IPv6 TCP transmission for me:

	ipv6: Preserve ipv6 functionality needed by NET

This patch fixes the typo "ipv6_offload" which should be
"ipv6-offload".

I don't know why not including the offload modules should
break TCP. Disabling all offload options on the NIC didn't
help. Outgoing pulseaudio traffic kept stalling.

ipv6: Preserve ipv6 functionality needed by NET

2012-11-18T07:34:00+00:00

Some pieces of network use core pieces of IPv6 stack.  Keep
them available while letting new GSO offload pieces depend
on CONFIG_INET.

ipv6: Pull IPv6 GSO registration out of the module

2012-11-15T22:39:24+00:00

Sing GSO support is now separate, pull it out of the module
and make it its own init call.
Remove the cleanup functions as they are no longer called.
