Subject: ADMtek ADM8511 "Pegasus II" USB Ethernet causes oops

From: Lincoln Ramsay <[email-masked]>
Date: Tue, 5 Apr 2016 20:31:33 +1000

Hello,

I have this (rather old) USB ethernet device but I cannot use it because 
it crashes my machine.

Simply plugging in the adapter and causing some traffic (pinging the 
gateway will do) causes an oops. With older kernels (3.10-3.19) this was 
generally nearly instant. With the current kernel (4.6 rc2) it can take 
longer to trigger (several minutes of pinging). Booting with the adapter 
inserted does not change the observed behaviour.

I found (via bisecting) that commit 
313a58e487ab3eb80e7e1f9baddc75968288aad9 causes the symptom. However, it 
looks like this just exposes an older, underlying problem. The 
underlying problem appears to be a skb buffer overrun. I think this 
overrun was not visible before this change due to the memory allocation 
pattern of the buffer pool.

I updated the code to avoid reading more data than the buffer can hold 
(see patch at the end) and I could use the adapter. My machine was up 
all day running this patch and doing network traffic over the adapter 
without issue.

/proc/version says
Linux version 4.6.0-040600rc2-generic (kernel@tangerine) (gcc version 
5.2.1 20151010 (Ubuntu 5.2.1-22ubuntu2) ) #201604031130 SMP Sun Apr 3 
15:32:46 UTC 2016

Here's an example oops (obtained via netconsole over the other ethernet 
interface). However, I doubt it's much use due to the nature of the 
issue. I have seen a variety of different oops messages while 
investigating this issue.
