I was able to determine the commit which introduced it for me: ===== commit 5d0c2b95bc57cf8fdc0e7b3e9d7e751eb65ad052 net: Preserve CHECKSUM_COMPLETE at validation Currently when the first checksum in a packet is validated using CHECKSUM_COMPLETE, ip_summed is overwritten to be CHECKSUM_UNNECESSARY so that any subsequent checksums in the packet are not correctly validated. This patch adds csum_valid flag in sk_buff and uses that to indicate validated checksum instead of setting CHECKSUM_UNNECESSARY. The bit is set accordingly in the skb_checksum_validate_* functions. The flag is checked in skb_checksum_complete, so that validation is communicated between checksum_init and checksum_complete sequence in TCP and UDP. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net> ===== Later there were more fixes related to checksum computation, but neither of those fixes mine (related to ppp/l2tp tunnel). All work seems to had been done by Tom Herbert so please assign this report to him as possible. There are several reports for this issue, it's not only me: https://bugzilla.redhat.com/show_bug.cgi?id=1148612 https://bugzilla.redhat.com/show_bug.cgi?id=1200635 https://lkml.org/lkml/2015/2/16/472 It is easily reproducible here, feel free to contact me for more information.
I've been getting this same one myself for a while now, although for me it started after kernel 3.17.8 (with 3.18). The stack traces I see are almost identical to those posted above by Darrien, though. I'm using ipsec_tools 0.8.2 + openl2tp 1.8 + ppp 2.4.7. I've tried every kernel released since 3.17.8 (just tried 4.0), and the problem has been perfectly consistent with every one of them.
I was scouring the net today as I continued to hope for some kind of fix to this problem, and I came across a mailing list archive wherein it looks like Tom Herbert had recently written a proposed patch. It isn't a terribly complex patch, so I tried it out on the most recent kernel (4.0.1). So far, it works, and my problem seems to have completely disappeared. I'm not sure what the (n)etiquette is here for posting a patch that was actually written by someone else, and I don't want to break any rules or decorum, so here's a link to the mailing list archive I came across: https://www.mail-archive.com/netdev@vger.kernel.org/msg63136.html The patches are buried within the reply tree, but there's only two short ones. I found it easy enough to just apply the changes by hand rather than copy/paste/reformat for the patch utility. If there's an appropriate way to include the embedded files here, I will leave that to someone "wiser" and more familiar with Linux kernel development than myself. If I experience any further developments that seem to be relevant to this supposed fix, I will post further comments. In the meantime, many thanks to Tom Herbert.
Thanks for finding that. I'll give it a try.
My patched build of kernel 4.0.1 operated without problems over the last couple of weeks. It looks like this fix has now been integrated into kernel 4.0.2 (commits 5a248fca60021d0e35a9de9bd0620eff840365ca and 8a6846e3226bb475db9686590da85bcc609c75a9). I've built 4.0.2 and confirmed that the problem has indeed been corrected (in my case, at least).
I have applied the fix on top of 3.19 and it fixed my problem.

I had the same issue with kernel 3.18.12. The patch fixed the issue. Now that I upgraded to kernel 4.0.3, I am getting the error. I verified that skbuff.h was patched in 4.0.3.
