Hi all,

As promised, here is a patch cleaning up can327's payload "encoding" 
(the hex dump part), plus a comment explaining why Dan's finding turned 
out not to be security relevant. It's as Vincent already explained, plus 
additional background information:

I've taken the liberty of not CC'ing the network maintainers on that 
patch, hence this email with a pointer to it for anyone interested. In 
the end, while it looked worrying at first, it ended up being just a 
minor cleanup.


Thanks Dan for pointing out that ugly piece of code. I'd really like to 
one day find the time to do some further cleanup, and especially further 
commenting in order to reduce the bus factor, but oh well...
