Not to my knowledge. Also depends on the exact issue. Reading through the
report there might be two separate issues.
1. Packet loss when this message appears. This is the the expected behaviour
when trying to transmit
a packet that would require more than 16+1 slots or 64kB.
Compared to the Amazon kernel mentioned all kernels later than 3.7 have the
following change:
* xen/netfront: handle compound page fragments on transmit
If there is something wrong with that, I have not yet seen a patch for it.
There might be a related bug
(bug #1275879) but hitting that would cause a BUG stacktrace in the guest.
2. That invalid socket state mentioned in comment #3. I wonder whether that
could hint the netback driver
running on the host side has closed the connection. There could be some
messages to help in the host's
dmesg but we cannot get to those (only Amazon can). If that is the case we
should ensure those two
patches are included in the kernel running in dom0 on the host:
* xen-netback: don't disconnect frontend when seeing oversize packet
* xen-netback: coalesce slots in TX path and fix regressions
