or route(8): it tells ifconfig(8) to try to resolve numbers to
hosts and service names.
This default ifconfig behavior stays the same as it always was.
when figuring out Where In The Kernel Is Carmen Sandiego's ioctl
for an ifconfig command line, since we can simply single-step into
the kernel.
Activated by "make RUMP_ACTION=1". No changes to normal case.
'address: ' field, don't treat the first address as the active address,
but search the link-layer addresses for the ones flagged IFLR_ACTIVE,
and print those. Extract a subroutine, print_link_addresses(), for
printing link-layer addresses.
That helps me get rid of some conditional compilation (INET6) in
ifconfig.
Let each protocol/feature-module print its own usage, so that the
ifconfig usage reflects the modules that are actually compiled-in.
Write usage information for carp(4) options.
various address families (inet, inet6, iso, atalk) and protocols
(802.11, 802.3ad, CARP), simply by trimming the list of sources in
the Makefile. This helps one customize ifconfig for an embedded
device or for install media, and it eliminates a lot of grotty
#ifdef'age. Now, the ifconfig syntax and semantics are finalized
at run-time using the constructor routines in each address-family/protocol
module.
(In principle, ifconfig could load virtually all of its syntax from
shared objects.)
Extract a lot of common code into subroutines, in order to shrink
the ifconfig binary a bit. Make all of the address families share
code for address addition/replacement/removal, and delete "legacy"
code for manipulating addresses. That may have broken atalk and
iso, despite my best efforts.
Extract an include file, Makefile.inc, containing the make-fu that
both ifconfig and x_ifconfig share.
Sprinkle static. Change some int's to bool's. Constify.
Add RCS Ids to carp.c and env.c. Move media code to a new file,
media.c. Delete several unneeded header files.
Set, reset, and display the IEEE 802.11 attribute, 'dot11RTSThreshold'.
Bug fix: do not require both a interface address and a destination
address for point-to-point interfaces, but accept a interface
address by itself.
1 Let us associate a keyword with either a signed or an unsigned
number. Associate the '-chan' keyword with an unsigned number.
This fixes the defect that crashed 'ifconfig wi0 -chan', reported
by Michael van Elst.
2 Do not try to interpret names as ISO addresses unless the ISO
address family was specified. iso_addr(3) does not report errors,
so it appears to interpret *everything* as an ISO address. This
is a stopgap fix for the defect in 'ifconfig lo0 inet6' on a
!INET6 kernel that deletes the first IPv4 address on lo0.

<http://mail-index.netbsd.org/tech-net/2008/04/08/msg000371.html>,
let us add, delete, and activate link-layer addresses with ifconfig:
# ifconfig sip0 link 02:00:00:00:00:01 [add address]
# ifconfig sip0 link 02:00:00:00:00:02 [add address]
# ifconfig sip0 link 02:00:00:00:00:02 active [activate address]
# ifconfig sip0 link 02:00:00:00:00:01 delete [remove address]
instead of zeroing them in commit_address().
Switch to in6_commit_address() from in6_getprefix() and in6_getaddr().
Temporarily add some debugging code to setia6eui64_impl().
When we read interface flags and capabilities from the kernel, take
care not to record them in our current environment (env), but record
them in the output environment (oenv), instead. This helps us get
interface capabilities and flags right.
to support IPv6 as well as IPv4 (a work in progress).
Make the second argument of af_status() a bool instead of an int.
Exit early with an error if the operator specifies an unsupported
address family on the command line. The change should help rc
scripts to detect that IPv6 support is missing from the kernel,
with 'ifconfig lo0 inet6'.
Start using prop_dictionary_util(3).
improved modularity and extensibility.
In the new architecture, a directed graph of argument-matching
objects (match objects) expresses the set of feasible ifconfig
statements. Match objects are labelled by subroutines that provide
the statement semantics.
Many IPv4, IPv6, 802.11, tunnel, and media configurations have been

Also, add ioctls SIOCGIFADDRPREF/SIOCSIFADDRPREF to get/set preference
numbers for addresses. Make ifconfig(8) set/display preference
numbers.
To activate source-address selection policies in your kernel, add
'options IPSELSRC' to your kernel configuration.
Miscellaneous changes in support of source-address selection:
1 Factor out some common code, producing rt_replace_ifa().
2 Abbreviate a for-loop with TAILQ_FOREACH().
3 Add the predicates on IPv4 addresses IN_LINKLOCAL() and
IN_PRIVATE(), that are true for link-local unicast
(169.254/16) and RFC1918 private addresses, respectively.
Add the predicate IN_ANY_LOCAL() that is true for link-local
unicast and multicast.
4 Add IPv4-specific interface attach/detach routines,
in_domifattach and in_domifdetach, which build #ifdef
IPSELSRC.
See in_getifa(9) for a more thorough description of source-address
selection policy.
if the kernel does not set the interface up after we set an address,
do it explicitly, unless we (previously) set it down on user request.
This will allow the network drivers to be "fixed" while keeping visible
behaviour the same. Part of fixing PR 30694.
