JIT doesn't work in SELinux #11

Closed Spivoxity closed 5 years ago

Spivoxity commented 5 years ago

Building on Fedora with SELinux enabled ends with the message

mprotect failed: Permission denied

This happens because the JIT tries to make memory pages that are simultaneously writable and executable, and SELinux doesn't allow that.

There are ways of avoiding this problem, as documented in this Firefox issue:

https://bugzilla.mozilla.org/show_bug.cgi?id=506693

But it's not really worth all the trouble. Options are to disable SELinux entirely, or disable it for the executable that's installed as /usr/local/lib/obc/obxj .
