* Fixed a segfault when configuring a static route in dhcpcd.conf
* Merged IPv6 ND and RA codebases
* Persistent configuration is now a default option in dhcpcd.conf
* Store configured IPv4 addresses against the interface so we only add
them if actually missing to avoid RTM_DELADDR/NEWADDR loops on some OS's
* waitip now supports waiting for any, IPv4, IPv6 or both protocols
* DHCPv6 addresses are added with a /128 prefix and should not attempt to
associate with any existing prefix or make one up as per RFC 5942
* Fix initial carrier status
* Fix requesting >1 DHCPv6 address
Fixes PR bin/48140
* dhcpcd will now assign a short hostname by default
To use a FQDN hostname, set this in dhcpcd.conf(5)
env hostname_fqdn=YES
* Only start DHCPv6 if the RA is new or has changed
* Fixed dhcpcd owning RA addressing and routes if disabled in kernel
* DHCPv6 support
* wpa_supplicant hook script
* route IPv4 addresses to 127.0.0.1 for machine centric traffic
* DHCPv6 Prefix Delegation support
* DHCPv6 FQDN support
* Control existing IPv4 routes
* less spamy to syslog by default
* IPv6 protocols now wait for a valid LL address before starting
* IPv6 DAD support now listens to kernel for more accurate timings
* IPv4 code split out more cleanly so dhcpcd can be compiled for
IPv4, IPv6 or IPv4 AND IPv6
* MTU is no longer requested by default
* a DUID is now generated in /etc/dhcpcd.duid and this is used as a
client ID for DHCPv4 and DHCPv6
This does mean that you may get new DHCPv4 addresses
Many bugs have also been fixed along the way and this release addresses

* add interface scope to exported IPv6 link local addresses
* DUID feature works again
* If we receive >1 MTU in the RA we use the last one
* Expire RA options separately from the RA
* Merge multiple RA options together except when a single is needed
* Some memory leaks plugged
* Don't overwrite invalid memory when DNSSL options begin with a NULL
* Ensure we have a large enough buffer for an escaped DNSSL option from RA
Improve IPv6 RA support by allowing dhcpcd to manage addreses and
routes instead of the kernel. dhcpcd will only do this if RA has been
disabled in the kernel or instructed to do so via the dhcpcd.conf(5)
ipv6ra_own and/or ipv6ra_owndefault directives.
Send and process IPv6 Neighbor Solicitions and Adverts to prove router
reachability. If a router cannot be reached in this way then it is
expired.
* Add a suffix to all our config files so that RA never stamps on IPv4
* All valgrind errors fixed on FreeBSD (with ./configure --debug=YES)
* When started with an interface list, respect that with signal handling
* Fix a potential route table corruption if we failed to add a route
* Stop checking IFF_RUNNING in RTM_IFINFO in an unknown link state
* RA expiry now tiggers off the first option if newer than the prefix
* Prefer a DHCP lease over an IPv4LL one
* Don't start IPv6 RS if disabled globally
* Allow dhcpcd to run on a read only filesystem
* Don't attempt to run the script if an empty string or /dev/null
* Stop truncating the netmask sockaddr on routing messages for BSD
* Shell portability fixes, including proper printf usage.
* Detect a valid ntp.conf before adjusting it
* reboot timeout changed to 5 seconds
* When rebooting and not daemonized, reduce the discover timeout
to allow for fallback or IPv4LL
* Respect each kernel carrier message
* Optimize some bitwise logic
* Don't remove interfaces for which commands have not been sent
* Store the assigned metric to each route so that we can change metrics on the fly
dhcpcd -n --metric 100 iwi0
* Add SixRD support, RFC5969
* Fix SIP server support
* Only regen resolv.conf if it has changed
* Fix --reconfigure from spinning
* Add IPv6 Router Solicitation support we regards to RDNSS and DNSSL, RFC6016
* syntax in 50-ypbind hook has been fixed
* man page corrections
* report hwaddr used by dhcpcd when debug is enabled
* Fix detecting inet address for INFORM support
* document reason RELEASE in dhcpcd-run-hooks
* Support RTM_CHGADDR in the upcoming NetBSD-6
This is used to work out if the hwaddr has changed as the interface
does not go down/up unlike other OSes
* ntp hook no longer attempts to restart ntpd if 1st attempt failed
* Use dynamically sized buffers for reading kernel link events
* Use the active link address
* Added option to dump a lease to stdout
* TEST mode now works correctly if an old lease is NAKed
* routes with the gateway = leased ip are now treated as host routes
* Fix crash when using clientid and the interface re-configures
* log the pid of dhcpcd
* Indicate server IP received message from even if server ID not
present
* Fix crashes on IPv4LL failure and add more logging
* VendorID is now dhcpcd-$version:$OS-$version:$machine:$platform
* IPv4LL address range can now be used in DHCP requests
* sysctl net.ipv4.conf.$iface.promote_secondaries enabled on Linux
This resolves a long standing issue of changing ip on the same subnet.
* IPv4LL correctly resets the DHCP timer.
* ClientID is now reported when interface starts.
* -w, --wait forces dhcpcd to wait until an interface gets a lease or
times out.
* Ensure DHCP socket is open when sending a DECLINE.
* Uses new hwaddr if existing interface is downed and then changed.
* No longer works on firewire interfaces by default.
dhcpcd-5.1.2 has a new behaviour change - when starting up and at least 1
interface has a carrier then it tries to get a lease or times out.
It still daemonises regardless. This, along with the -b and -w flags
allows total control over the desired behaviour of dhcpcd.
Major changes from dhcpcd-4 include
* Single daemon can now run DHCP on multiple interfaces at the same time
* Configuration profiles per interface, ssid, arping and fallback
* Listens to 3rd party programs changing routing information
* Supports DHCP INFORM over PPP
* Can configure static options for destination address
* Control socket so 3rd party program can control or listen directly
to dhcpcd events
* Is also a BOOTP client
DHCP_DECLINE now includes the IP and Server in the message.
Trailing NULLs are stripped from string options.
ntpd is only restarted if it is already running.
ClientID is no longer sent by default.
CSR comes before routers and static routes as per RFC 3442.
Host routes are now added correctly.
If a the interface link flaps but status does not change, do not reset the timer.
- support for link state notification (e.g. renew lease after carrier
returned)
- support to start go into background immediately
- don't cleanup interface state. dhcpcd will leave the interface in the
same state as before if the lease uses separate addresses. -p still
stops it from removing the configured address on exit
- various smaller bugfixes, optimisations and cleanups
