I was making use of a 'protocol private' part of the per-packet 'skbuff' structure to store some useful info. Comments in Linux seemed to indocate that whoever currently had the skbuff queued could safely use this area. This is actually untrue (at least for net devices, which admittedly isn't protocol code :-) ). Just so happened that for certain packet types and timings we'd overwrite TCP info in that area which caused havoc. -- Keir > Great !! > > So what was causing this bug? > > sachin > > Keir Fraser <Keir.Fraser@xxxxxxxxxxxx> wrote: > > This domain-crashing bug should now be fixed in the unstable > repository.
