📄 Description

Quickfix for problem found in SELinux (CVE-2016-7545) that affects Firejail too.
See https://security-tracker.debian.org/tracker/CVE-2016-7545 and http://seclists.org/oss-sec/2016/q3/606.
Fixed by calling setsid() as done in SELinux. Side effect of this is broken job control in shell:

$ firejail --quiet
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell
$ fg
bash: fg: no job control
$ bg
bash: bg: no job control

But this should be fine until somebody comes with better solution.

EDIT: grsecurity prevents exploitation of this problem.
