This 19 includes various WITNESS- related kernel options, INVARIANTS, malloc 20 debugging flags in userland, and various verbose features in the 21 kernel. Many developers choose to disable these features on build 22 machines to maximize performance. (To disable malloc debugging, run 23 ln -s aj /etc/malloc.conf.) 24 2520100913: | 1Updating Information for FreeBSD current users 2 3This file is maintained and copyrighted by M.

| 26 The $ipv6_prefer variable in rc.conf(5) has been split into 27 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 28 29 The $ip6addrctl_policy is a variable to choose a pre-defined 30 address selection policy set by ip6addrctl(8). A value 31 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 32 default is "AUTO". 33 34 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 35 flag (see an entry of 20090926) is set on an interface with no 36 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 37 security reason. If you want IPv6 link-local address on all 38 interfaces by default, set this to "YES". 39 40 The old ipv6_prefer="YES" is equivalent to 41 ipv6_activate_all_interfaces="YES" and 42 ip6addrctl_policy="ipv6_prefer". 43 4420100913: |

| 26 DTrace has grown support for userland tracing. Due to this, DTrace is 27 now i386 and amd64 only. 28 dtruss(1) is now installed by default on those systems and a new 29 kernel module is needed for userland tracing: fasttrap. 30 No changes to your kernel config file are necessary to enable 31 userland tracing, but you might consider adding 'STRIP=' and 32 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 33 to have informative userland stack traces in DTrace (ustack). --- 1159 unchanged lines hidden (view full) --- 1193HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, 1194STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING 1195IN ANY WAY OUT OF THE USE OF THIS SOFTWARE, EVEN IF ADVISED OF THE 1196POSSIBILITY OF SUCH DAMAGE. 1197 1198Contact Warner Losh if you have any questions about your use of 1199this document. 1200 | 45 DTrace has grown support for userland tracing.
