(To disable malloc debugging, run ln -s aj /etc/malloc.conf.) +20090926: + The rc.d/network_ipv6, IPv6 configuration script has been integrated + into rc.d/netif. The changes are the following: + + 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF + for IPv4. For aliases, $ifconfig_IF_aliasN should be used. + Note that both variables need the "inet6" keyword at the head. + + Do not set $ipv6_network_interfaces manually if you do not + understand what you are doing. It is not needed in most cases. + + $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but + they are obsolete. + + 2. $ipv6_enable is obsolete. Use $ipv6_prefer and + "inet6 accept_rtadv" keyword in ifconfig(8) instead. + + If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and + all configured interfaces have "inet6 accept_rtadv" in the + $ifconfig_IF_ipv6. These are for backward compatibility. + + 3. A new variable $ipv6_prefer has been added. If NO, IPv6 + functionality of interfaces with no corresponding + $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, + and the default address selection policy of ip6addrctl(8) + is the IPv4-preferred one (see rc.d/ip6addrctl for more details). + Note that if you want to configure IPv6 functionality on the + disabled interfaces after boot, first you need to clear the flag by + using ifconfig(8) like: + + ifconfig em0 inet6 -ifdisabled + + If YES, the default address selection policy is set as + IPv6-preferred. + + The default value of $ipv6_prefer is NO. + + 4. If your system need to receive Router Advertisement messages, + define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) + scripts automatically invoke rtsol(8) when the interface becomes + UP. The Router Advertisement messages are used for SLAAC + (State-Less Address AutoConfiguration). + 20090922: 802.11s D3.03 support was committed. This is incompatible with the previous code, which was based on D3.0. +20090912: + A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value + of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to + control whether accepting Router Advertisement messages or not. + Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and + a sysctl variable net.inet6.ip6.auto_linklocal is its default value. + The ifconfig(8) utility now supports these flags. + 20090910: ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for mount(8) and -a option for df(1) to see them. |
