REDHAT-BUG-726552

First published: Fri Jul 29 2011(Updated: )

Currently skb_gro_header_slow unconditionally resets frag0 and frag0_len. However, when we can't pull on the skb this leaves the GRO fields in an inconsistent state. This patch fixes this by only resetting those fields after the pskb_may_pull test. Upstream commit: <a href="http://git.kernel.org/linus/17dd759c67f21e34f2156abcf415e1f60605a188">http://git.kernel.org/linus/17dd759c67f21e34f2156abcf415e1f60605a188</a> Acknowledgements: Red Hat would like to thank Brent Meshier for reporting this issue.
