(these can be controled by the ipv6rs/noipv6rs directive)
* fix a crash receiving SIGUSR1

* internal routing is now protocol agnostic
* avoid using __packed and use compile time asserts instead

release taraballs from this point onwards
* default DBDIR has changed from /var/db to /var/db/dhcpcd
* /etc/dhcpcd.duid moves to DBDIR/duid

inside a directory of the same name
* fixed issues with reject routes not working on some platforms
* improved nl80211 support on Linux for working out the SSID
* no longer request NTP by default in dhcpcd.conf
* BPF filtering vastly improved so dhcpcd only wake up on
ARP or DHCP packets destined for it
* support for MUD URL (draft-ietf-opsawg-mud-05)
* if the kernel isn't doing DAD, don't insist on waiting for it
to actually do it
* fix a potential crash where the DHCP or ARP states could be
freed before the packet processing loop naturally breaks
* removed gateway and nogateway options
(these can be controlled by the nooption directive which
works for more than just gateways)
* removed ipv6ra_own and ipv6ra_own_default options
(these can be controled by the ipv6rs/noipv6rs directive)
* fix a crash receiving SIGUSR1

Update to dhcpcd-9.0.0 with the following changes:

* Decode interface complex interface names eth0.100:2 eth0i100:2.
This allows us to ignore some virtual interfaces by default

* DHCP: Support jumbo frames (untested)
* DHCP6: Clean up old lease on failure to confirm/rebind, etc
* RA: Prefer older routers
* INET6: Obscure prefixes are now calculated correctly

* Privilege Separation
* default hostname is now a blank string rather than localhost
* Leases are now dumped over the control socket - you get RA's now as well.

* routes: dhcpcd added host routes are now reported correctly

branches: 1.1.1.5.2;
Import dhcpcd-7.0.0 with the following changes:
* dhcp: when unicasting on L3, unicast on L2 as well
* dhcp: when rebooting, don't set cidaddr
* dhcp6: don't listen on IPv6 addresses when not using DHCPv6

* IPv6 default route is now deleted when config is not persistent
* Use hmac(3) if available in libc to reduce binary size

Fixes PR bin/52554

branches: 1.1.1.3.2;
Import dhcpcd-7.0.0-rc1 with the following changes:
* Default to use VLANID>0 for IAID instead of MAC address
* Stop sharing the DHCPv6 port in master mode with other processes
* Fix some prefix delegation issues when the carrier drops or
addresses become stale
* Fix a crash when starting dhcpcd with -n
* Fix test for preferring a fake lease over a real one
* Show to real address lifetimes being added when adding IPv6
addresses

branches: 1.1.1.2.2; 1.1.1.2.4; 1.1.1.2.6;
Import dhcpcd-7.0.0-beta3 with the following changes:
* restored --logfile support as a few people complained it vanished
The new logging code even makes the overall binary size smaller
on most platforms.
* BPF filter now trims garbage trailing the payload
OK, it's not garbage, but userland doesn't know some drivers append
FCS to it.
* support NetBSD's RO_MSGFILTER socket option to reduce avoid context
switching for route(4) messages that don't interest us.
* Don't open sockets if just sending signals.
* HMAC-MD5 test's now check expectations in code rather than relying
on visual confirmation.
* added eloop-bench to test performance of eloop with available
polling mechanisms.

Import dhcpcd-7.0.0-beta. Changes from prior version include:

* source file locations reworked:
dhcpcd source is in src
dhcpcd hooks are in hooks
compat is in compat
* README split into README.md and BUILDING.md
* internal routing is now protocol agnostic
* avoid using __packed and use compile time asserts instead
* addresses some alignment issues
* disable some ARP code on kernels which support RFC5227
* BSD IPv6 kernel settings are now updated to reflect dhcpcd config
* custom logger has been removed, syslog handles everything
as such, the --logfile option has been removed as well.
If you need better/earlier logging, get a better syslogger!
* distinfo and signed distinfo files are now available alongside
release taraballs from this point onwards
* default DBDIR has changed from /var/db to /var/db/dhcpcd
* /etc/dhcpcd.duid moves to DBDIR/duid
* /etc/dhcpcd.secret moves to DBDIR/secret
* lease file names have dhcpcd removed from them as they are now
inside a directory of the same name
* fixed issues with reject routes not working on some platforms
* improved nl80211 support on Linux for working out the SSID
* no longer request NTP by default in dhcpcd.conf
* BPF filtering vastly improved so dhcpcd only wake up on
ARP or DHCP packets destined for it
* support for MUD URL (draft-ietf-opsawg-mud-05)
* if the kernel isn't doing DAD, don't insist on waiting for it
to actually do it
* fix a potential crash where the DHCP or ARP states could be
freed before the packet processing loop naturally breaks
* removed gateway and nogateway options
(these can be controlled by the nooption directive which
works for more than just gateways)
* removed ipv6ra_own and ipv6ra_own_default options
(these can be controled by the ipv6rs/noipv6rs directive)
* fix a crash receiving SIGUSR1

Import dhcpcd-8.0.2 with the following changes:

* NetBSD: Can be build without ARP support but listen to kernel DaD
* ND6: Removed NA support from SMALL builds

* distinfo and signed distinfo files are now available alongside
release taraballs from this point onwards
* default DBDIR has changed from /var/db to /var/db/dhcpcd
* /etc/dhcpcd.duid moves to DBDIR/duid
* /etc/dhcpcd.secret moves to DBDIR/secret
* lease file names have dhcpcd removed from them as they are now
inside a directory of the same name
* fixed issues with reject routes not working on some platforms
* improved nl80211 support on Linux for working out the SSID
* no longer request NTP by default in dhcpcd.conf
* BPF filtering vastly improved so dhcpcd only wake up on
ARP or DHCP packets destined for it
* support for MUD URL (draft-ietf-opsawg-mud-05)
* if the kernel isn't doing DAD, don't insist on waiting for it
to actually do it
* fix a potential crash where the DHCP or ARP states could be
freed before the packet processing loop naturally breaks
* removed gateway and nogateway options
(these can be controlled by the nooption directive which
works for more than just gateways)
* removed ipv6ra_own and ipv6ra_own_default options
(these can be controled by the ipv6rs/noipv6rs directive)
* fix a crash receiving SIGUSR1

Import dhcpcd-7.0.0-rc1 with the following changes:
* Default to use VLANID>0 for IAID instead of MAC address
* Stop sharing the DHCPv6 port in master mode with other processes
* Fix some prefix delegation issues when the carrier drops or
addresses become stale
* Fix a crash when starting dhcpcd with -n
* Fix test for preferring a fake lease over a real one
* Show to real address lifetimes being added when adding IPv6
addresses
* Restore the -G, --nogateway option

branches: 1.1.1.2.4; 1.1.1.2.6;
Import dhcpcd-7.0.0-beta3 with the following changes:
* restored --logfile support as a few people complained it vanished
The new logging code even makes the overall binary size smaller
on most platforms.
* BPF filter now trims garbage trailing the payload
OK, it's not garbage, but userland doesn't know some drivers append
FCS to it.
* support NetBSD's RO_MSGFILTER socket option to reduce avoid context
switching for route(4) messages that don't interest us.
* Don't open sockets if just sending signals.
* HMAC-MD5 test's now check expectations in code rather than relying
on visual confirmation.
* added eloop-bench to test performance of eloop with available
polling mechanisms.

Import dhcpcd-7.0.0-beta. Changes from prior version include:

* source file locations reworked:
dhcpcd source is in src
dhcpcd hooks are in hooks
compat is in compat
* README split into README.md and BUILDING.md
* internal routing is now protocol agnostic
* avoid using __packed and use compile time asserts instead
* addresses some alignment issues
* disable some ARP code on kernels which support RFC5227
* BSD IPv6 kernel settings are now updated to reflect dhcpcd config
* custom logger has been removed, syslog handles everything
as such, the --logfile option has been removed as well.
