Ethereal-dev: [Ethereal-dev] Re: rev 17612: /trunk/epan/dissectors/: packet-tcp.c
I would say it is likely 2 bytes of kernel memory that is leaked here.
The question is "what kind of memory is leaked?"
In the most bening case it would just be a buffer from a previous
received packet that is reused and thus it is just the checksum from
that packet.
In a less bening case ...
In any case I think the kernel guys should have a look at it and avoid
this leak regardless.
woohoo ethereal found a kernel bug !
