2019-03-18	Use same idiom for pretty_print_domain_search() and	Kenneth R Westerback
	pretty_print_classless_routes(), making both of them local to options.c. Avoids a double pretty print of DHO_DOMAIN_SEARCH, eliminates an unneeded 1024 byte static array. Shrinks size of upcoming diff to implement parsing of domain search option in leases and dhclient.conf.
2019-03-18	Add a couple of checks to ensure option data fits into the proposal	Kenneth R Westerback
	field being memcpy()'d into. Tweak DHO_ROUTERS handling to be similar to the other cases populating proposal->rtstatic, including a warning when things go wrong.
2019-03-18	explicitly use BPF_FILDROP_CAPTURE when configuring BIOCSFILDROP	David Gwynne
	BIOCSFILDROP used to just be a flag, ie, any non-zero value was treated the same, but i'm changing it so different values do different things. this way the programs should keep working even if i decide to change the values for these macros.
2019-02-26	add domain-search to the list of options capable of adding to resolv.conf;	Jason McIntyre
	confirmed by and ok krw
2019-02-23	Correct comment on delete_addresses() return value.	Kenneth R Westerback

2019-02-23	Restore pre-a2k19 behaviour of clearing out all existing addresses	Kenneth R Westerback
	when setting new address. That change needs specific consideration rather than inadvertant inclusion, especially after claiming no functional change was being made. Change and related problems noted and reversion tested by Kurt Mosiejczuk.
2019-02-16	SSID/LLADDR/LINK_STATE_IS_UP changes must discard the previous	Kenneth R Westerback
	proposal to ensure the new lease is applied to the interface.
2019-02-13	Nuke unused variable.	Kenneth R Westerback

2019-02-13	Try harder to start a new line when link is obtained and a new	Kenneth R Westerback
	message is about to be displayed on the console.
2019-02-12	Restructure code to simplifiy imsg communications, further separating	Kenneth R Westerback
	DHCP knowledge and interface manipulation. Unprivileged process now sends proposal derived from the accepted lease to the privileged process rather than individual interface manipulation requests. The only intended functional change is that /etc/resolv.conf.tail is not re-read each time a new proposal is implemented, rather than once at dhclient startup.
2019-01-26	Rename ACTION_NONE to ACTION_USELEASE. TOK_NOACTION to TOK_USELEASE.	Kenneth R Westerback
	More consistent, clearer.
2019-01-26	Zap trailing space that stuck its head up.	Kenneth R Westerback

2019-01-26	Add 'uselease' statement to allow the disabling of built-in or	Kenneth R Westerback
	previously specified 'append', 'default', 'ignore', 'prepend', or 'supersede' actions on the values provided in leases.
2019-01-22	Simply the logic translating 'egress' into an interface name.	Kenneth R Westerback

2019-01-21	Allocate buffer before using it.	Kenneth R Westerback
	Encountered, diagnosed, fix tested and ok jca@
2019-01-21	Typo. "nterface" -> "interface"	Kenneth R Westerback

2019-01-20	Don't delay signal(SIGPIPE, SIG_IGN) until go_daemon() does it. First,	Kenneth R Westerback
	go_daemon() may not be called before the first error. Second, go_daemon() doesn't do anything when '-d' is specified.
2019-01-19	Since there is no more exec()'ing, there is no need to	Kenneth R Westerback
	save a copy of the original argv.
2019-01-19	Since dhclient no longer tries to clean up when exiting, there is no	Kenneth R Westerback
	need to start a new copy when LLADDR or SSID changes. Just go back to S_PREBOOT and get a new lease. Fewer log messages, faster join'ing new networks, simpler code.
2019-01-19	IMSG_HUP -> IMSG_RESTART. sendhup() -> sendrestart.	Kenneth R Westerback

2019-01-19	Drop pseudo-signal idiom. Rename INTERNALSIG to TERMINATE. Use RESTART	Kenneth R Westerback
	instead of overloading SIGHUP.
2019-01-19	'quit' no longer holds signals, so strsignal(quit) is both pointless	Kenneth R Westerback
	and now in unreachable code. Simplifies dispatch loops by eliminating most uses of INTERNALSIG.
2019-01-19	'quit' is no longer set in a signal handler so it no longer needs to	Kenneth R Westerback
	be sig_atomic_t. Plain int should be sufficient.
2019-01-18	Move link state change test & check for new lladdr into	Kenneth R Westerback
	interface_state(). Simplifies code a bit.
2019-01-18	Ignore HUP signals. If you need to modify the running configuration	Kenneth R Westerback
	just run dhclient again, which does the same thing. i.e. kills existing dhclient processes and exec's a new copy. One less knob. Improves documention by eliminating very non-standard SIGNALS section. Feedback from schwarze@. ok deraadt@
2019-01-18	Oops. Nuke debug statement that snuck it.	Kenneth R Westerback

2019-01-18	Shuffle lease file reading code to improve clarity and shorten some	Kenneth R Westerback
	lines. No intentional functional change.
2019-01-18	Yet another long line broke cover.	Kenneth R Westerback

2019-01-18	Be consistent in explicitly testing memcmp() return values.	Kenneth R Westerback

2019-01-17	Split a long line that wandered into the	Kenneth R Westerback
	crosshairs.
2019-01-17	Split a long line that wandered into the	Kenneth R Westerback
	crosshairs.
2019-01-17	Move "link X -> Y" debug messages into insterface_state() where	Kenneth R Westerback
	the link field is actually modified. Thus catching all places where a link state change might be detected.
2019-01-14	Make apply_ignore_list(), set_default_hostname(),	Kenneth R Westerback
	set_default_client_identifier() and read_resolv_conf_tail() local to clparse.c and just call them from read_conf().
2019-01-14	Abstract allocation and initialization of config global	Kenneth R Westerback
	variable into init_config() and just call it from read_conf().
2019-01-14	set_default_client_identifier() only needs the	Kenneth R Westerback
	struct ether_addr (a.k.a. ifi->hw_address) rather than the entire struct interface_info.
2019-01-14	Check NULLness of ignore list inside apply_ignore_list() and not	Kenneth R Westerback
	before calling it.
2019-01-13	Abstract /etc/resolv.conf.tail reading out of main()	Kenneth R Westerback
	and into a read_resolv_conf_tail() in clparse.c.
2019-01-13	White space nits.	Kenneth R Westerback

2019-01-13	Shuffle apply_ignore_list(), set_default_client_identifier() and	Kenneth R Westerback
	set_default_host_name() to clparse.c as they are part of config initialization. First step in cleanup of startup logic.
2019-01-10	"AF_* values are almost always the correct choice, particularly with	Kenneth R Westerback
	POSIX APIs". Also sprach guenther@. So switch PF_ROUTE to AF_ROUTE in socket() and setsockopt() calls. Keep PF_ROUTE in sysctl(2) uses. adding a comment for future visitors, Also replace PF_UNSPEC with 0 in socketpair(), as socketpair(2) points out this is the only sensible value. Cluebat from and ok guenther@
2019-01-09	Use PF_ROUTE consistently rather than tossing in	Kenneth R Westerback
	a couple of AF_ROUTE.
2019-01-05	Simplify and clarify (i.e. shrink) code processing	Kenneth R Westerback
	the bpf captures.
2019-01-05	KNF nit.	Kenneth R Westerback

2019-01-03	The need for separate bpf and routing message buffers was eliminated	Kenneth R Westerback
	when dhclient moved to processing the entire buffer rather than trying to process one packet per dispatch() loop. So use ifi->rbuf for both purposes, resizing it during initialization to accommodate the larger of the routing socket read size or the bpf socket read size. Eliminates a calloc()/free() per routing socket read.
2018-12-28	Join other daemons in assuming that a single read from a routing	Kenneth R Westerback
	socket may contain more than one RTM_* message. Adopt the claudian variant (pointer arithmetic/comparison) of doing this. The isolation of dhclient in assuming each routing socket read will return only one message pointed out by Gregor Best.
2018-12-27	Rename ufdesc to udpfd to make the code slightly more intuitive.	Kenneth R Westerback

2018-12-27	Rename routehandler() to routefd_handler() to make the code slightly	Kenneth R Westerback
	more intuitive.
2018-12-27	Rename bfdesc to bpffd and packethandler() to bpffd_handler() to make	Kenneth R Westerback
	the code slightly more intuitive.
2018-12-27	No need to return early when setting the tick stop.	Kenneth R Westerback

2018-12-25	No need for magic tick_msg(NULL,..) call to	Kenneth R Westerback
	set stop time. The stop time is always config->link_timeout seconds after the first call to tick_msg().
