D29832 doesn't work. D29832 addressed the *already solved* stack gap issue in ntpd. The problem people failed to realize was that it wasn't stack gap but PIE. Enabling PIE regardless of the stack gap sysctl setting always resulted in the error. Ultimately a sledgehammer approach was the only way to address it. -- Cheers, Cy Schubert <[email protected]> FreeBSD UNIX: <[email protected]> Web: https://FreeBSD.org NTP: <[email protected]> Web: https://nwtime.org The need of the many outweighs the greed of the few. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/dev-commits-src-all To unsubscribe, send any mail to "[email protected]"
