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, -- David Palma
