Update of /cvsroot/src/external/bsd/dhcpcd/dist
In directory ivanova.netbsd.org:/tmp/cvs-serv9006

Log Message:
Import dhcpcd-6.4.0 with the following changes:

  *  Only fork when the RA has a RDNSS option AND a valid prefix OR no DHCPv6 
instruction.
  *  Handle BSD per interface rtadv kernel flag.
  *  Add a reject route for the delegated prefix so that unassigned prefixes 
don't go back upstream.
  *  If not specified, Delegated Prefixes will get an automatic SLA of the 
interface index. If the biggest SLA and the assigned prefix fits into a /64 
then dhcpcd creates a /64 prefix so that SLAAC works. If bigger than /64 is 
needed then dhcpcd creates one rounded upto the nearest multiple of 8. Unless a 
configured SLA of 0 is assigned, a reject route for the Delegated Prefix is 
installed to stop unassigned addresses trying to be resolved upstream. 
Addresses added from Delegated Prefixes now have a default address suffix of 1 
instead of using a SLAAC style address.
  *  Don't spam timezone updates unless its actually changed.
  *  Support ND6_IFF_OVERRIDE_RTADV on BSD.
  *  Document why we don't send both FQDN and hostname options.
  *  Respect RFC4861 MAX_RTR_SOLICITATION_DELAY as specified in section 6.3.7.
  *  RFC2131 section 4.4.1 states the client SHOULD wait a random time between 
one and ten seconds to desynchronize the use of DHCP at startup. Instead we 
wait a random time between zero and one second to mirror the more modern IPv6RS 
and DHCPv6 standards unless overridden by defining RFC2131_STRICT.
  *  Always send a carrier as it's no longer encapsulated in the IPv4 stack. 
When stopping and not departed, run with the STOPPED reason but do not process 
it in hooks.
  *  Poll kernel neighbour reachability (SIOCGNBRINFO_IN6) for each router 
instead of sending and listening for Neighbour Soliciation/Advertisement 
packets. The kernel is privy to a lot more reachability information than 
userland is.
  *  Ensure that ND6_IFF_PERFORMNUD is set.
  *  controlgroup option changes group ownership of the control socket.
  *  Should use arc4random_uniform when wanting a randon number between 1 and 
N. Improve the compat arc4random function a little and re-stir on fork.
  *  -4 and -6 are now mutually exclusive and when running on a single 
interface per protocol pidfiles are created. This means that other control 
options suchs as -x and -n will require the -4 or -6 option as well.
  *  Implement Stable Private Addresses for SLAAC as per RFC7217. Enable this 
as default in dhcpcd.conf.
  *  Log error condition if a new or changed Router Advertisment to avoid 
spamming the log.
  *  Add an IPv6 link-local address before upping the interface if needed. 
Bring an interface up when we start it and not during discovery. As such, stop 
waiting on carrier for a second if we did.
  *  Add gateway option to enable the gateway or an interface/profile. Ensure 
the option and require options disable the nooption option - last wins.
  *  Restarting ntp/yp are not critical and their initialisation continues in 
the background as well so we may as well background the restart commands for 
faster dhcpcd performance.
