*	net: Fix GRE RX to use skb_transport_header for GRE header offset	Tom Herbert	2014-09-08	1	-3/+2
\| \| \| \| \| \| \| \| \| \| \| \|	GRE assumes that the GRE header is at skb_network_header + ip_hrdlen(skb). It is more general to use skb_transport_header and this allows the possbility of inserting additional header between IP and GRE (which is what we will done in Generic UDP Encapsulation for GRE).

*	gre: Add support for checksum unnecessary conversions	Tom Herbert	2014-09-01	1	-0/+4
\| \| \| \| \| \| \| \| \| \| \|	Call skb_checksum_try_convert and skb_gro_checksum_try_convert after checksum is found present and validated in the GRE header for normal and GRO paths respectively. In GRO path, call skb_gro_checksum_try_convert Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
*	net: Clarification of CHECKSUM_UNNECESSARY	Tom Herbert	2014-08-29	1	-1/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch: - Clarifies the specific requirements of devices returning CHECKSUM_UNNECESSARY (comments in skbuff.h). - Adds csum_level field to skbuff. This is used to express how many checksums are covered by CHECKSUM_UNNECESSARY (stores n - 1). This replaces the overloading of skb->encapsulation, that field is is now only used to indicate inner headers are valid. - Change __skb_checksum_validate_needed to "consume" each checksum as indicated by csum_level as layers of the the packet are parsed. - Remove skb_pop_rcv_encapsulation, no longer needed in the new csum_level model.

*	gre: When GRE csum is present count as encap layer wrt csum	Tom Herbert	2014-08-24	1	-0/+1
\| \| \| \| \| \| \| \|	In GRE demux if the GRE checksum pop rcv encapsulation so that any encapsulated checksums are treated as tunnel checksums. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
*	GRE: enable offloads for GRE	Amritha Nambiar	2014-07-11	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \|	To get offloads to work with Generic Routing Encapsulation (GRE), the outer transport header has to be reset after skb_push is done. This patch has the support for this fix and hence GRE offloading.

*	gre: Call gso_make_checksum	Tom Herbert	2014-06-04	1	-1/+2
\| \| \| \| \| \| \| \| \| \| \|	Call gso_make_checksum. This should have the benefit of using a checksum that may have been previously computed for the packet. This also adds NETIF_F_GSO_GRE_CSUM to differentiate devices that offload GRE GSO with and without the GRE checksum offloaed. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S.

*	ip_tunnel: Fix dst ref-count.	Pravin B Shelar	2014-03-26	1	-0/+8
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Commit 10ddceb22ba (ip_tunnel:multicast process cause panic due to skb->_skb_refdst NULL pointer) removed dst-drop call from ip-tunnel-recv. Following commit reintroduce dst-drop and fix the original bug by checking loopback packet before releasing dst.

*	gre_offload: statically build GRE offloading support	Eric Dumazet	2014-01-06	1	-9/+0
\| \| \| \| \| \| \| \| \| \| \| \|	GRO/GSO layers can be enabled on a node, even if said node is only forwarding packets. This patch permits GSO (and upcoming GRO) support for GRE encapsulated packets, even if the host has no GRE tunnel setup. Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: H.K.

*	ipv4: generalize gre_handle_offloads	Eric Dumazet	2013-10-19	1	-29/+0
\| \| \| \| \| \| \| \| \| \|	This patch makes gre_handle_offloads() more generic and rename it to iptunnel_handle_offloads() This will be used to add GSO/TSO support to IPIP tunnels. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
*	net: gre: move GSO functions to gre_offload	Daniel Borkmann	2013-07-03	1	-0/+414
	Similarly to TCP/UDP offloading, move all related GRE functions to gre_offload.c to make things more explicit and similar to the rest of the code.
