Subject: [PATCH v4 ipsec-next 0/3] xfrm: Support GRO decapsulation for ESP in
UDP encapsulation
Hello,
Here I re-worked this patch set and here is v4.
v1->v2 fixed error path added skb_push
use is_fou instead of holding sk in skb.
user configurable option to enable GRO; using UDP_GRO
v2->v3 only support GRO for UDP_ENCAP_ESPINUDP and not
UDP_ENCAP_ESPINUDP_NON_IKE. The _NON_IKE is an IETF early draft
version and not widly used.
v3->v4 removed refactoring since refactored function is only used once
removed refcount on sk, sk is not used any more.
fixed encap_type as Eyal recommended.
removed un-necessary else since there is a goto before that.
We are not merging v4 and v6 functions at this moment. As it would
need more work to do it cleanly.
Steffen Klassert (3):
xfrm: Use the XFRM_GRO to indicate a GRO call on input.
xfrm: Support GRO for IPv4 ESP in UDP encapsulation.
xfrm: Support GRO for IPv6 ESP in UDP encapsulation.
