Message-ID: <41EC1406.6040500@kavefish.net> (raw)
In-Reply-To: <20050117201901.3e712cfa.khali@linux-fr.org>
I'm hoping someone can help explain part of the layout of a process'
virtual address space in the 2.6 series kernel.
Below is the output of "cat /proc/self/maps" on Fedora Core 3
(2.6.9-1.6_FC2) with exec-shield[-randomize] disabled and
legacy_vm_layout enabled.
What is being mapped in at last line (ffffe000-fffff000 ---p)? This is
always there, no matter what process I run. To my knowledge, this
wasn't the case on 2.4.

I have not had much success in my search for information via Google &
IRC and the books I have are specific to the 2.4 series. Any help would
be greatly appreciated.
