Subject: [PATCH v2 next-next 00/12] ipv6: Enable GUEoIPv6 and more fixes for v6 tunneling
Date: Fri, 6 May 2016 13:04:44 -0700 [thread overview]
Message-ID: <1462565096-4076043-1-git-send-email-tom@herbertland.com> (raw)
This patch set:
- Fixes GRE6 to process translate flags correctly from configuration
- Adds support for GSO and GRO for ip6ip6 and ip4ip6
- Add support for FOU and GUE in IPv6
- Support GRE, ip6ip6 and ip4ip6 over FOU/GUE
- Fixes ip6_input to deal with UDP encapsulations
- Some other minor fixes
v2:
- Removed a check of GSO types in MPLS
- Define GSO type SKB_GSO_IPXIP6 and SKB_GSO_IPXIP4 (based on input
from Alexander)
- Don't define GSO types specifally for IP6IP6 and IP4IP6, above
fix makes that uncessary
- Don't bother clearing encapsulation flag in UDP tunnel segment
(another item suggested by Alexander).
Tested:
Tested a variety of case, but not the full matrix (which is quite
large now). Most of the obivous cases (e.g. GRE) work fine. Still
some issues probably with GSO/GRO being effective in all cases.
