All code under the GPL. Note that many Linux Distributions contain some
non-GPL code in them, so you have to separate it out.

It is allowed. Instead of posting ported GPL code on sourceforge, I
could make it a pay for download somewhere else. I could not stop
anyone else from making it a lower cost or free download to compete with
me though.
Think of it this way. If I were the only source of compiled a GPL
package built for VMS that was needed for a niche, but profitable
market, then I could charge for it. My customers, who after paying me
my fee, could make my port free, but why should they? That could be
helping a competitor, and it could cause me to stop supporting a product
that they need.
It could be way more expensive for them to hire their own person to port
that package.
Most of the time the sellers of GPL code are selling either additional
non-GPL content, advanced access to tested GPL bug fixes, or other
support services.
But yes, some are just selling for profit what you can download for free.
