New Revision: 253683
URL: http://svnweb.freebsd.org/changeset/base/253683
Log:
MFC 253262, 253318, 243184, 253444, 253505, 253520:
- Add a leaf node CTL_NET.PF_ROUTE.0.AF.NET_RT_DUMP.0.FIB. This returns
routing table with the specified FIB number, not td->td_proc->p_fibnum.
- Add check_namevarlist() to check if ${name}_var is reserved in
rc.subr or not.
- Fix a bug in ipv6_prefix_IF. It did not work with the 64-bit prefix
notation like 2001:db8:1:1.
- Use eui64 flag in ifconfig(8) instead of network6_getladdr()[*] for
interface indentifier part.
- Fix address range specification with ifconfig(8) options such as:
* inet 192.0.2.1-10 netmask 255.255.255.0 (inet range spec + ifconfig
options)
* inet6 2001:db8:1::1-f prefixlen 60 (inet6 range spec + ifconfig options)
If prefixlen or netmask option is specified with CIDR notation at
the same time, the option is used.
- Do not set ND6_IFF_ACCEPT_RTADV on if_bridge(4) interfaces when
ipv6_enable=yes.
