MFS r272855, 266846:

• Do not override sin6_scope_id in LLA when it is already set to non-zero. This fixes destination list in output of netstat -r.
• Plug a memory leak.
• Add RTM_VERSION check.
• Fix a bug which can make sysctl() fail when -F is specified.
• Increase WID_IF_DEFAULT() from 6 to 8 (the default for AF_INET6) because we have interfaces with longer names than 6 chars like epairN{a,b}.
• Style fixes.

MFS r272847:

• Add rwlock to struct dadq. A panic could occur when a large number of addresses performed DAD at the same time.

MFS r272850:

• Replace Sun RPC license in TI-RPC library with a 3-clause BSD license, with the explicit permission of Sun Microsystems in 2009.
• Replace Sun Industry Standards Source License for Sun RPC code with a 3-clause BSD license as specified by Oracle America, Inc. in 2010. This license change was approved by Wim Coekaerts, Senior Vice President, Linux and Virtualization at Oracle Corporation.
• Replace Sun RPC license with a 3-clause BSD license. This license change was approved in 2010 by Wim Coekaerts, Senior Vice President, Linux and Virtualization at Oracle Corporation.
• Replace Sun RPC license for TI-RPC library with a 3-clause BSD license, with the explicit permission of Sun Microsystems in 2009. The code in question in this file was copied from lib/libc/rpc/pmap_getport.c.

MFS r272852,r272853:

• Add relative specification in expiration time.
• Add proto3 option for RTF_PROTO3.
• Use %lu for members of struct rt_metrics.
• Use long explicitly for the time difference.

MFS r272854:

• Return 0 if:
  1. "-u N" specified, no -f, and mdN found,
  2. no -u, "-f /pathname" specified, and mdN associated with /pathname found,
  3. "-u N" specified, "-f /pathname" specified, and both of them found,
  4. "-l" specified and no -f,
  5. "-l" specified, "-f /pathname" specified, and /pathname found.
     
     otherwise return -1.

MFS r272856:

• Move configuration of IPv6 NDP flags to a point before handling ifconfig_IF. This fixes a race that a non-IPv4 interface can get an EUI64 LLA even if it has IFDISABLED nd6 flag at boot time.

MFS r272857:

• Cancel DAD for an ifa when the ifp has ND6_IFF_IFDISABLED as early as possible and do not clear IN6_IFF_TENTATIVE. If IFDISABLED was accidentally set after a DAD started, TENTATIVE could be cleared because no NA was received due to IFDISABLED, and as a result it could prevent DAD when manually clearing IFDISABLED after that.

MFS r272858:

• Fix an issue in range specification handling when a "-foo" is specified in ifconfig_IF_aliasN.

MFS r272859:

• Fix EtherIP. TOS field must be initialized when the inner protocol is PF_LINK, and multicast/broadcast flag should always be dropped because the outer protocol uses unicast even when the inner address is not for unicast. It had been broken since r236951 when gif_output() started to use IFQ_HANDOFF().

MFS r272860:

• Recover sin6_scope_id of gateway addresses in riprecv() by using the if_index where a RIP packet was received. This fixes a bug which prevented gateway addresses in fe80::/64 from being added.

MFS r272861:

• Fix rc.d/gssd script to define the default values in a standard way.
• Use a parameter argument in jls(8) instead of doing grep.

MFS r272862, r272870:

• Restructure rc.d scripts for kerberos5 daemons.

MFS r272863:

• Return false status only when adding a route is failed. It could erroneously return false due to an afexists() check loop in routing_start().

MFS r272864:

• Use ipv6_prefer when at least one ifconfig_IF_ipv6 is configured.

MFS r272865:

• Fix a bug which prevented mount.fstab parameter from being converted when jail_JID_devfs_enable=NO.

MFS r272866:

• Fix header output when -P is specified and (ncpus - 1) != maxid.

MFS r272867:

• Fix a bug which could break extended attributes in a dump output. This occurred when a file was >892kB long and had a large data (>1kB) in the extended attributes.

MFS r272868, r272869:

• Make net.inet.ip.sourceroute, net.inet.ip.accept_sourceroute, and net.inet.ip.process_options vnet-aware.

MFS r272871:

• Revert changes in r269180. It could cause -c N option to enter an infinite loop if no reply packet is received.

MFS r272874:

• Resurrect set_rcvar() as a function to define a rc.conf variable. It defines a variable and its default value in load_rc_config() just after rc.conf is loaded. "rcvar" command shows the current and the default values.

MFS r272960:

• Do not add late flag when file= is specified because it has a bad side-effect. The specified file should exist before the fstab line.
