Bug#592187: Bug#576838: virtio network crashes again
Hi Ben, Greg,
I was finally able to identify the patch series that introduced the fix
(they were introduced to -stable in 2.6.33.2):
cb63112 net: add __must_check to sk_add_backlog
a12a9a2 net: backlog functions rename
51c5db4 x25: use limited socket backlog
c531ab2 tipc: use limited socket backlog
37d60aa sctp: use limited socket backlog
9b3d968 llc: use limited socket backlog
230401e udp: use limited socket backlog
20a92ec tcp: use limited socket backlog
ab9dd05 net: add limit for socket backlog
After applying these to 2.6.32.17, I wasn't able to trigger the failure
anymore.
230401e didn't apply cleanly with git cherry-pick on top of 2.6.32.17,
so there might be some additional work needed.
@Greg: would it be possible to have these fixes in the next 2.6.32? See
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=592187#69 for details:
they fix a guest network crash during heavy nfs-io using virtio.
Kind regards,
Lukas
