* Fixed octal and hex string parsing in options.
* Several statically sized buffers have been removed and replaced
with dynamically sized ones where we have no real idea of what
the size will be.
* Reverse IPv4 route removal order.
* Added --small configure directive to reduce binary size
* Allow DHCPv6, IPv4lL and authentication to be compiled out
* Add support for ifa_addrflags in getifaddrs(3)
* Add support for ifam_addrflags and ifam_pid from route(4)
* If T1 or T2 are not set in DHCPv6 messages, use a default from the
lowest pltime instead of the expiration time.
* Validate lease before moving to REQUEST when both ends use
rapid commit.
* If lease validation fails, don't restart the DISCOVER phase if
we're already in it.
* Fix IPv6 prefix underflow when confirming deprecated but valid leases
* eloop.c and .h are now 100% portable outside of dhcpcd
(provided the system supports recent POSIX and either you or
the system provide working TAILQ macros)
* Allow waitip to work per interface.
* Handle ND options in the same way we handle DHCP and DHCPv6 options.
* Add new variable of type bitflags:flags where the flags ABCDEFGH,
A is 10000000, B is 01000000, etc.
Variables with the name reserved are no longer processed.
* Improve IN_IFF_TENTATIVE with ip sharing.
* Use the exit code of EXIT_SUCCESS when terminating gracefully.
* Fix dumping a lease file by filename.
* If RTF_LOCAL is defined, don't try and set loopback routes.
* Fix adding host routes on BSD.
* After adding an address load the kernel routing table for the
interface. When routes are rebuilt try not to remove any existing
routes if they don't need changing.
* Replace timeval with timespec for our internal functions.
* Support kqueue(2).
* Better support for more interface types on BSD, thanks to Guy Yur.
* Many Prefix Delegation fixes.
* Fix creation of normal IPv6 link-local addresses overflowing the
address storage and fooling dhcpcd into thinking it's not
tentative when added.
* Add own syslog(3) like logging function for a nicer output and so
we can log to a file for the case when syslogd(8) starts after
dhcpcd so we can log any errors during system start using the new
--logfile option.
* Only release the DHCPv6 lease when dropping it.
* Fix handling of ND6_IFF_OVERRIDE_RTADV on BSD.
* Include paths.h to get _PATH_BPF. Thanks to Joerg Sonnenberger.
* Report a better error of the kernel lacks a BPF equivalent filter.
* Implement RFC4941, Privacy Extensions for Stateless Address
Autoconfiguration in IPv6 when dhcpcd is overriding the in-kernel
RA support. For BSD, this is a full userland implementation.
* reject <option> will now reject any DHCP message that contains
that option.
* Ignore RA's from ourself for very badly configured stations.
