How to disable destructive dtrace ?

[Alain De Vos]

Is it a setting in rc.conf or sysctl.conf ?
I know there is "kern.features.kdtrace_hooks" but no idea what it's good for.

echo security.bsd.allow_destructive_dtrace=0 >> /boot/loader.conf

Thanks. My current loader.conf :

currdev="zfs:ZT2/ROOT/default:"
vfs.root.mountfrom="zfs:ZT2/ROOT/default"
zfs_load="YES"
cc_cubic_load="YES"
autoboot_delay=60
loader_logo=none
aesni_load="YES"
geom_eli_load="YES"
cryptodev_load="YES"

hw.pci.do_power_nodriver=3
hw.usb.no_boot_wait=1
kern.geom.label.disk_ident.enable=0
kern.racct.enable=1
kern.sc.color.0.rgb="#210021"
kern.sc.color.7.rgb="#ffff10"
kern.sc.color.15.rgb="#10ffff"
kern.vty=sc
security.bsd.allow_destructive_dtrace=0

if you're using FreeBSD >= 13.0 aesni is part of the kernel.

If you are using 14.0 cc_cubic is default.
