Hello,
FYI, W^X is now more strictly enforced on OpenBSD so DrRacket is not
going to work anymore be default:
https://marc.info/?l=openbsd-misc&m=147273821220405
"We are pleased to announce the official release of OpenBSD 6.0.
[...]
- Security improvements:
o W^X is now strictly enforced by default; a program can only
violate it if the executable is marked with PT_OPENBSD_WXNEEDED
and is located on a filesystem mounted with the wxallowed mount(8)
option. Because there are still too many ports which violate W^X,
the installer mounts the /usr/local filesystem with wxallowed.
This allows the base system to be more secure as long as
/usr/local is a separate filesystem. If you use no W^X violating
programs, consider manually revoking that option."
The PT_OPENBSD_WXNEEDED part means that executables need to be linked
using ld's -z wxneeded option (which is new and does not work in
previous versions of OpenBSD): http://man.openbsd.org/OpenBSD-current/man1/ld.1
Cheers,
Philippe
