Log message:
Import dhcpcd-7.2.2 with the following changes:
  *  DHCP: Ensure dhcp is running on the interface received from
  *  BSD: Link handling has been simplified, however it is expected
     that if an interface supports SIOCGIFMEDIA then it reports
     the correct link status via route(4) for reliable operations
  *  BPF: ARP filter is more robust
  *  BSD and sun: Validate RTM message lengths

This security issue has been addressed
  *  DHCPv6: Fix a potential read overflow with D6_OPTION_PD_EXCLUDE

Many thanks to Maxime Villard <max@m00nbsd.net> for discovering this issue.

Log message:
Import dhcpcd-7.2.1 with the following changes:
*  Solaris: Many more issues fixed
*  OpenBSD: Don't spam syslog when cannot send NA
*  FreeBSD: Fix fetching IPv6 address lifetimes

These security issues are also addressed:
*  auth: Use consttime_memequal to avoid latency attack
   consttime_memequal is supplied if libc does not support it
   dhcpcd >=6.2 <7.2.1 are vulnerable

*  DHCP: Fix a potential 1 byte read overflow with DHO_OPTSOVERLOADED
   dhcpcd >=4 <7.2.1 are vulnerable

*  DHCPv6: Fix a potential buffer overflow reading NA/TA addresses
   dhcpcd >=7 <7.2.1 are vulnerable

Many thanks to Maxime Villard <max@m00nbsd.net> for discovering these issues.

Log message:
Import dhcpcd-7.1.1 with the following changes:

* IPv4LL: Fixed build with this disabled

* BSD: Fixed initial link infos reported as LINK_STATE_UNKNOWN
* FreeBSD: Avoid panicing kernel for IPv6 prefix routes

Log message:
dhcpcd-7.1.0 has been released with the following changes:

* OpenBSD: works alongside slaacd(8)
* NetBSD: sets SO_RERROR on to detect receive socket overflow
* BSD: route improvements to avoid listening for own changes
* Linux: use NETLINK_BROADCAST_ERROR
* BSD: avoid late address deletion messages by testing address existance
* IP6: implement IP6 address sharing
* BSD: catch UP/DOWN events when interfaces does support media changes
* IPv4LL: remember old address when carrier is lost

Log message:
Import dhcpcd-7.0.8 with the following changes:
  *  Don't use IP_PKTINFO on NetBSD-7 as it's incomplete.
  *  Workaround RTM_NEWADDR sending the wrong broadcast address
     on NetBSD-7.
  *  Silence diagnostics if an address vanishes when reading
     it's flags on all BSD's.
  *  Misc compiler warnings fixed.

Log message:
Import dhcpcd-7.0.7 with the following changes:
  *  host routes work correctly again
  *  vlanid is also used to calculate slaac stable private addresses

Log message:
Import dhcpcd-7.0.5 with the following changes:

  *  dhcp: Clarified some checksumming code, style and commentary
     (thanks to Maxime Villard)
  *  dhcp6: IAID is now unique per IA type rather than global
  *  ip6: if an IA callback causes a fork, exit earlier

Log message:
