Hi,
Is there a way in FreeBSD by which we can restrict few contiguous instruction pages to read and write to only to few pages? Basically I am trying to restrict dynamically linked libraries to read and write only pages linked due to dynamically linked library and only few pages of the global data in the rest of the process address space.
Can this be done using linker directives or by modifying page level bits within the kernel?
Regards,
Mahesh
