| |
-stable review patch. If anyone has any objections, please let us know.
------------------ From: Herbert Xu <herbert@gondor.apana.org.au>
The skb_postpull_rcsum introduced a bug to the checksum modification. Although the length pulled is offset bytes, the origin of the pulling is the GRE header, not the IP header.
