    Total Security Fail

    Finally, ASLR support in 2014

    20Fucking14
    . Wonder how many simple exploits have occurred on production servers.

      Probably none. ASLR isn't really a big deal. It wouldn't have saved you from Heartbleed.

        iOS have 64-bit ARM (AArch64) support.

        Apple derived iOS from OS X, which was derived from NextStep, which was derived from FreeBSD?

        Now BSD have to implement 64-bit ARM support themselves?

          Wouldn't have happened (legally) with GPL

            How can they port something from Linux if they want everything to be BSD-licensed and Linux is GPL?

              I read they're updating the so called "linuxator" from the current fedora 10 base installation. This was in attempt to try make the linux version of steam work. I wonder how well, if possible, freebsd would be able to run linux games?

                Isn't sony using one of the BSD kernel forks for their playstation 4?

                  Yes, a modified version of one of the 9.0 releases.

                    NextStep wasn't derived from FreeBSD, FreeBSD as a distribution didn't exist back then. NextStep took what it needed from BSD Unix.
                    Yes, the FreeBSD community has to port ARM64 all over again because FreeBSD and OSX although cousins are not at all compatible, OSX has a completely different kernel.
                    Apple released their ARM64 documentation which was picked up by the LLVM community and will be amalgamated with their own AArch64 implementation so on the compiler front it will be covered for the FreeBSD guys. <--- This was actually covered by Phoronix.

                      Actually it would have happened in exactly the same way.

                      Apple release the source code to their XNU kernel - but porting it to FreeBSD isn't as easy as you think. Though the two share a lot of code, the entire lower half and driver model of Apple's XNU is different to FreeBSD. It's not some copy and paste job.

                      In re porting from Linux: The DRI stack is BSD licensed; this was agreed back in the XFree86 days as a means of allowing Linux, the BSDs, and Solaris to combine their efforts in driver support.

                          Impressive. I wonder what's causing it.

                            Wrong,

                            ASLR solves almost all of the loopholes which exists in SSP, NX, W^X, ExecSheld and Libsafe. ASLR is a very big thing and FreeBSD is therefore a big blunder. OpenBSD only randomizes the top of thier stack which is not effective.

                            Linux however, randomizes thier entire address space (Stack, Heap etc.).

                              This an unfair benckmark. PCBSD used an old version of KDE while Unbuntu used the lastest Unity interface which slowed it down. Know with the slow, bloated ZFS, the results will be very different. And I mean very very different.
