Bug 518398 – gnome-base/gnome-shell-3.12* - gnome-shell-extension-prefs needs paxmarking

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Alexander Tsoy 2014-07-28 17:10:13 UTC]

/usr/bin/gnome-shell-extension-prefs needs "pax-mark m" on my system. Given the fact that it is linked with libffi, it may need "pax-mark E" as well.

$ ldd /usr/bin/gnome-shell-extension-prefs | egrep 'js|ffi'
	libgnome-shell-js.so => /usr/lib64/gnome-shell/libgnome-shell-js.so (0x000002c7c9751000)
	libgjs.so.0 => /usr/lib64/libgjs.so.0 (0x000002c7c94c4000)
	libmozjs-24.so => /usr/lib64/libmozjs-24.so (0x000002c7c7c10000)
	libffi.so.6 => /usr/lib64/libffi.so.6 (0x000002c7c707b000)

@hardened, do you see it ok? (I have no problem on changing ebuild as it works better for you)

Thanks

- no need to add PaX flag "E" if binary already have flag "m" (s/if/elsif/)
- mark with "m" if libffi is compiled with USE=-pax_kernel (last "else" block)
