(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 $ipv6_enable is obsolete.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. diff --git a/etc/network.subr b/etc/network.subr index f9c10e8..83141ec 100644 --- a/etc/network.subr +++ b/etc/network.subr @@ -97,15 +97,26 @@ ifconfig_up() if afexists inet6; then if ipv6if $1; then if checkyesno ipv6_gateway_enable; then - _ipv6_opts="-accept_rtadv auto_linklocal" - else - _ipv6_opts="auto_linklocal" + _ipv6_opts="-accept_rtadv" fi else - _ipv6_opts="-auto_linklocal ifdisabled" + if checkyesno ipv6_prefer; then + _ipv6_opts="-ifdisabled" + else + _ipv6_opts="ifdisabled" + fi + + # backward compatibility: $ipv6_enable + case $ipv6_enable in + [Yy][Ee][Ss]) + _ipv6_opts="${_ipv6_opts} accept_rtadv" + ;; + esac fi - ifconfig $1 inet6 ${_ipv6_opts} + if [ -n "${_ipv6_opts}" ]; then + ifconfig $1 inet6 ${_ipv6_opts} + fi # ifconfig_IF_ipv6 ifconfig_args=`ifconfig_getargs $1 ipv6` @@ -382,7 +393,7 @@ noafif() # 1 otherwise. ipv6if() { - local _if i + local _if _tmpargs i _if=$1 if ! afexists inet6; then @@ -396,6 +407,18 @@ ipv6if() ;; esac + # True if $ifconfig_IF_ipv6 is defined. + _tmpargs=`_ifconfig_getargs $_if ipv6` + if [ -n "${_tmpargs}" ]; then + return 0 + fi + + # backward compatibility: True if $ipv6_ifconfig_IF is defined. + _tmpargs=`get_if_var $_if ipv6_ifconfig_IF` + if [ -n "${_tmpargs}" ]; then + return 0 + fi + case "${ipv6_network_interfaces}" in [Aa][Uu][Tt][Oo]) return 0 @@ -431,17 +454,30 @@ ipv6_autoconfif() if checkyesno ipv6_gateway_enable; then return 1 fi + _tmpargs=`get_if_var $_if ipv6_prefix_IF` + if [ -n "${_tmpargs}" ]; then + return 1 + fi case $_if in lo0|\ stf[0-9]*|\ faith[0-9]*|\ lp[0-9]*|\ - sl[0-9]*) + sl[0-9]*|\ + pflog[0-9]*|\ + pfsync[0-9]*) return 1 ;; esac + # backward compatibility: $ipv6_enable + case $ipv6_enable in + [Yy][Ee][Ss]) + return 0 + ;; + esac + _tmpargs=`_ifconfig_getargs $_if ipv6` for _arg in $_tmpargs; do case $_arg in @@ -451,6 +487,16 @@ ipv6_autoconfif() esac done + # backward compatibility: $ipv6_ifconfig_IF + _tmpargs=`get_if_var $_if ipv6_ifconfig_IF` + for _arg in $_tmpargs; do + case $_arg in + accept_rtadv) + return 0 + ;; + esac + done + return 1 } @@ -691,7 +737,7 @@ ifalias_ipv6_up() ;; *) ifconfig $1 inet6 ${ifconfig_args} alias && _ret=0 - warn "\$ipv6_ifconfig_$1_alias${alias} is obsolete." + warn "\$ipv6_ifconfig_$1_alias${alias} is obsolete." \ " Use ifconfig_$1_aliasN instead." ;; esac @@ -773,6 +819,7 @@ ifalias_ipv6_down() done # backward compatibility: ipv6_ifconfig_IF_aliasN. + alias=0 while : ; do ifconfig_args=`get_if_var $1 ipv6_ifconfig_IF_alias${alias}` case "${ifconfig_args}" in @@ -780,13 +827,12 @@ ifalias_ipv6_down() break ;; *) - ifconfig $1 inet6 ${ifconfig_args} -alias - alias=$((${alias} + 1)) - warn "\$ipv6_ifconfig_$1_alias${alias} is obsolete." + ifconfig $1 inet6 ${ifconfig_args} -alias && _ret=0 + warn "\$ipv6_ifconfig_$1_alias${alias} is obsolete." \ " Use ifconfig_$1_aliasN instead." - _ret=0 ;; esac + alias=$((${alias} + 1)) done return $_ret diff --git a/etc/rc.d/ip6addrctl b/etc/rc.d/ip6addrctl index 518ac25..66f1952 100755 --- a/etc/rc.d/ip6addrctl +++ b/etc/rc.d/ip6addrctl @@ -19,6 +19,8 @@ status_cmd="ip6addrctl" prefer_ipv6_cmd="ip6addrctl_prefer_ipv6" prefer_ipv4_cmd="ip6addrctl_prefer_ipv4" +set_rcvar_obsolete ipv6_enable ipv6_prefer + ip6addrctl_prefer_ipv6() { ip6addrctl flush >/dev/null 2>&1 diff --git a/etc/rc.d/netif b/etc/rc.d/netif index ac2cc58..3c8e5dc 100755 --- a/etc/rc.d/netif +++ b/etc/rc.d/netif @@ -41,7 +41,7 @@ clonedown_cmd="clone_down" extra_commands="cloneup clonedown" cmdifn= -set_rcvar_obsolete ipv6_enable +set_rcvar_obsolete ipv6_enable ipv6_prefer network_start() { diff --git a/sbin/ifconfig/ifconfig.8 b/sbin/ifconfig/ifconfig.8 index de241e7..220bd9f 100644 --- a/sbin/ifconfig/ifconfig.8 +++ b/sbin/ifconfig/ifconfig.8 @@ -28,7 +28,7 @@ .\" From: @(#)ifconfig.8 8.3 (Berkeley) 1/5/94 .\" $FreeBSD$ .\" -.Dd September 2, 2009 +.Dd September 23, 2009 .Dt IFCONFIG 8 .Os .Sh NAME @@ -598,7 +598,10 @@ If the interface was reset when previously marked down, the hardware will be re-initialized. .El .Pp -The following parameters are for ICMPv6 Neightbor Discovery Protocol: +The following parameters are for ICMPv6 Neightbor Discovery Protocol. +Note that the address family keyword +.Dq Li inet6 +is needed for them: .Bl -tag -width indent .It Cm accept_rtadv Set a flag to enable accepting ICMPv6 Router Advertisement messages. @@ -619,7 +622,10 @@ Clear a flag .Cm defaultif . .It Cm ifdisabled Set a flag to disable all of IPv6 network communications on the -specified interface. +specified interface.
