-This is POC to demonstrate the inheritance of -m pax flags when
-a binary, which is not marked -m, loads a library which is marked -m.
+This is POC to demonstrate the inheritance of MPROTECT PaX flag when
+a binary loads a library, either via normal dynamic linking or via dlopen.
+The binary/library are variously marked -M (enabled) or -m (disabled) MPROTECT.
+
+The library contains an RWX mmapping which is forbiddent. The binary just
+calls the library.

0. Preferrably do this on the One True Distro, hardened gentoo.
- 1. Run a pax enabled kernel with RANDMMAP
+ 1. Run a pax enabled kernel with PAX_MPROTECT
2. Install sys-apps/paxctl
