Subject: Re: [PATCH net-next 0/3] ila: Support for checksum neutral

From: Tom Herbert <>
Date: Sat, 23 Apr 2016 11:46:54 -0700

> This patch set updates ILA to support draft-herbert-nvo3-ila-02. The
> primary addition is support checksum neutral ILA translation.
> This allows address to be performed and still keep any transport
> layer checksums that include the addresses in their pseudo header to
> still be correct without the translator needing to parse L4.
> Other items are:
>    - Structures for ILA addresses, identifiers, locators
>    - Disallow translation on non-ILA addresses (check by
>      type in identifier).
>    - Change xlat (nf_input) to translates solely based
>      on matching locators not identifiers (since identifiers
>      are not obfuscated by checksum neutral).
>    - Side effect if above is that multiple ILA domains are
>      supported. Each local locator can map to a different
>      SIR address (ILA domain), and each domain defines its
>      own identifier space.
> Tested: Ran TCP_RR with 200 cnxs. ILA performance is slightly better
> than previously since we are not longer parsing L4 for checksum
> handling. I amd seeing about 1% performance overhead. Also ran
> TCP_STREAM and tested non-ILA address (type=0) are not translated.
> v2: Fix complilation errors

Series applied.

There were some conflicts I had to resolve due to the recent 64-bit
padding fixes, but those weren't too difficult to deal with.
