Bug description:
Upstream stable releases 4.4.34 and 4.8.10 introduced a regression
that is already fixed in mainline but hasn't been applied to stable
kernels yet (nor to Ubuntu kernels). Here's the thread where the bug
was reported:
http://lkml.iu.edu/hypermail/linux/kernel/1611.2/04851.html
Here's a partial transcript of the report:
"This update broke PXE boot on our 4-way AMD boxes. The kernel panics in
eth_type_trans(), presumably during kernel-level IP autoconfiguration,
see [1]. Bisection points me at 5c67f947 (net: __skb_flow_dissect()
must cap its return value). And indeed, reverting this commit fixes
the problem for me."
This issue is fixed with mainline commit:
commit c9b8af1330198ae241cd545e1f040019010d44d9
Author: Eric Dumazet <[email protected]>
Date: Tue Nov 22 11:17:30 2016 -0800
flow_dissect: call init_default_flow_dissectors() earlier
