Subject: skb_over_panic using UDP and 6lowpan / fakelb
Date: Mon, 27 Mar 2017 11:16:47 +0200 [thread overview]
Message-ID: <56012235-e1d0-1e5e-840a-cc8d5938c380@ntnu.no> (raw)

Hi,
Sending a simple UDP packet (39 bytes long), over a 6lowpan interface
(using fakelb), creates a kernel panic (skb_over_panic).
Steps to reproduce, and more details, can be found in:
https://github.com/PalmaITEM/6lowpan-skb_over_panic
This bug has been reported in
https://bugzilla.kernel.org/show_bug.cgi?id=195059
I have found that lengths around 39 bytes can also trigger this
behaviour and that longer packets are handled without problem.
Verified in:
- Linux version 4.9.0-0.bpo.2-amd64 (debian-kernel@lists.debian.org)
(gcc version 4.9.2 (Debian 4.9.2-10) ) #1 SMP Debian 4.9.13-1~bpo8+1
(2017-02-27)
- Linux version 4.10.4-1-ARCH (builduser@tobias) (gcc version 6.3.1
20170306 (GCC) ) #1 SMP PREEMPT Sat Mar 18 19:39:18 CET 2017
I am not familiar with the process of reporting kernel bugs, so
apologies beforehand. I am also available to provide any missing
information.
Cheers,
