Author: allanjude Date: Mon Oct 2 14:19:31 2017 New Revision: 324206 URL: https://svnweb.freebsd.org/changeset/base/324206 Log: bsdinstall(8) hardening menu: Utilize new kern.randompid=1 behaviour Enabling the PID randomization option in bsdinstall(8)'s hardening menu now randomizes the effective value of kern.randompid on each boot. Previous behaviour: When kern.randompid was enabled via the the bsdinstall(8) hardening menu, a random value was generated and placed in the systems /etc/sysctl.conf as kern.randompid=value This makes the value of kern.randompid static across reboots. New behaviour: When kern.randompid is enabled via the bsdinstall(8) hardening menu, the line kern.randompid=1 is placed in the systems /etc/sysctl.conf. This takes advantage of a new kernel feature and makes the value of kern.randompid be randomized by the kernel on each reboot.
