Hi Sven,

is there a special reason why you don't have implemented the 'attach_at'-support to a local address in the base-linux code?

I need this feature (and my fix seems to work well here).

in constrast to the L4 platforms, on which 'attach_at' is needed for constructing child address spaces, we had no use for 'attach_at' on Linux so far. We simply start processes using 'execve' and leave the allocation of virtual memory to the Linux kernel.

I'll also need this feature in the base-okl4 code (and I would try to add it also there if necessary...)

It is there already. ;-)

Is there any risk/ nasty surprise when using it?

On Linux, you'll have to make assumptions about how the Linux kernel allocates mmap regions. I would try to avoid relying on such heuristics. Do you have a particular reason for specifying local addresses for 'mmap()'?
