RE: [Xen-devel] (repeatable) cross-domain networking failure

["Ian Pratt" <m+Ian.Pratt@xxxxxxxxxxxx>]

OK, I have a good handle on the problem with UDP hangs into user-space
of domain 0.

It's down to message size: if the UDP payload size is less than 24
bytes, the buffer is not freed properly. Bizarre, but it explains why
our regression tests weren't picking it up as they all use larger
message sizes.

Anyhow, now we can reproduce, a fix should be forthcoming.
