Dear Linux developers,
I recently discovered that the Linux kernel on 32 bits x86 processors
reports the stack as being non-executable while it is actually
executable (because located in the same memory segment).
this is not per se true, it depends on the capabilities of your 32 bit
x86 processor.
# grep maps /proc/self/maps
bfce8000-bfcfe000 rw-p bfce8000 00:00 0 [stack]
this shows that the *intent* is to have it non-executable.
Not all x86 processors can enforce this. All modern ones do.
Is there any reason for this situation?
the alternative (showing effective permission) is equally confusing;
apps would see permissions they didn't set...
Why not show both.
"intent" and "effective".
