Re: ipv6 connection hash function wanted ...

ze: 1. Calculate src_ip xor dst_ip [result is 16 bytes]. 2. Calculate (src_port + pkey) * (dst_port + pkey) [result is 4 bytes, using 32bit modulo arithmetics]. 3. Run crc32_raw on the resulting 20 bytes, using ckey as initialization vector. pkey and ckey are two different 32bit rando

utility. You can look at their cvsweb here: http://www.dragonflybsd.org/cvsweb/src/usr.bin/fstat/ However, I suspect that they have also made modifications to the kernel interfaces in order to support the fstat utility, so their improvements to that utility might not be applicable t

Re: Init.c, making it chroot

t.c The chroot() patch has been committed with r1.6. It uses kenv to specify the chroot directory, so it can easily be set by the loader(8), e.g. using a custom boot menu. Best regards Oliver PS: I see NetBSD has a similar feature, too. Maybe FreeBSD should join the crowd and adopt it.
