* 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.
* fixed compile issues with prior release
* fixed carrier loss not being detected for IPv4
* UUID based DUID is used where available and no prior DUID exists
* 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
* Routing: Fix case when cloning route changes but needs to be replaced
* DHCP6: Transpose DHCP userclass option into DHCP6
* DHCP6: Fix sending custom vendor class option
* Auth: Allow zero value replay detection data
* Auth: Allow different tokens for send and receive
* ND6: Warn if router lifetime is set to zero
* DHCP6: Softwire Address and Port-Mapped Clients, RFC7598
* dhcp6: fix a null termination overflow on status messages
* options: static routes can be setup in global context again
* routes: dhcpcd added host routes are now reported correctly
* Added support for setproctitle(3)
* Kernel RA is no longer disabled when IPv6 is disabled in dhcpcd
* DHCPv6 PD is no longer stopped if no Routers are found
* If the DHCP leased address is deleted, enter the reboot state
* DHCPv6 unicast is no longer performed when not in master mode
* dhcpcd will now detect netlink/route socket overflows ad re-sync
- HAVE_GCC=5 is now the default (vs. HAVE_GCC=53 we've been using for
GCC 5.4 and GCC 5.5.)
- remove some more GCC 4.8 code. we don't support GCC 4 here.
- adjust set lists to gcc=5 from gcc=53.
add some basic HAVE_GCC=6 handling (totally unused so far.)
* hooks: remove use of local builtin for better portability
* dhcpcd: don't log errors working out carrier for departed interfaces
* ipv4: allow configuration of static broadcast address
* if: don't set MTU during interface discovery
* if: don't activate non matching interfaces to commandline ones
* eloop-bench: fix hangs when using a large number of cycles
* dhcp: don't bind when we've just probed an address to inform
* 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
* dhcp: only set probe state when probing (fixes REBOOT reason)
* ipv6: disable kernel RA if interface is active
* hooks: set protocol to link for link layer events
* Don't flush prefix routes/routers if kernel does not support RA
* dhcp: improve errors around UDP checksum failure
* dhcp: announce existing addresses before rebooting
* bpf: rework loop so that we can close/reopen fd inside and abort
* ipv6nd: don't handle NA/RA for non active interfaces
* dhcp6: listen on all addresses in non master mode
* dhcpcd-run-hooks: set protocol in dhcpcd, don't guess
* Ensure that xid is unique across all interfaces
* dhcp6: redirect message to interface which uses the xid
* bsd: strip scope from LL addresses when detecting their addition
* ipv6nd: fix address lifetime overflow on carrier up
* dhcp6: fix confirmation of lease on carrier up
* Fixed handling RA's from multiple routers
* Fixed changing to a better route based on gateway
* 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
* 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
* 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.
