Subject: probable bug in pktgen
Date: Tue, 12 Oct 2004 17:01:47 -0700 [thread overview]
Message-ID: <416C706B.5030300@candelatech.com> (raw)
While testing my own pktgen code I noticed that I can cause spectacular
crashes by setting the 'multiskb' to > 1 and using VLAN interfaces. I
believe this is because the virtual device changes the skb->dev pointer
when it xmits, and then pktgen tries to send exactly this pkt again,
even though the skb->dev is now hosed up.
Unfortunately, my patch will not do the kernel pktgen much good, but
next time someone is hacking there, maybe they can fix it :)
