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.
Fix MOBILE encapsulation. Add many debugging printfs (mainly
concerning UDP mode). Clean up the gre(4) code a bit. Add the
capability to setup UDP tunnels to ifconfig. Update documentation.
In UDP mode, gre(4) puts a GRE header onto transmitted packets,
and hands them to a UDP socket for transmission. That is, the
encapsulation looks like this: IP+UDP+GRE+encapsulated packet.
There are two ways to set up a UDP tunnel. One way is to tell the
source and destination IP+port to gre(4), and let gre(4) create
the socket. The other way to create a UDP tunnel is for userland
to "delegate" a UDP socket to the kernel.
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.

to automatically bring up interfaces, then we should move that code into
ifconfig(8) and out of the kernel, not cycle the interface up and down. Fixes

want to use a hex ssid, you precede it with a 0x, which really needed
documenting.)

However, he suggested using -c, and cgd (reasonably) noted that -z for
"zero" was probably more reasonable.
I've also changed the code very slightly.
* bssid xx:xx:xx:xx:xx:xx -- set the desired BSSID of an 802.11
interface.
* -bssid -- unset the desired BSSID of an 802.11 interface, so
the interface will choose automatically (default).
* channel x -- set the channel (radio frequency) of an 802.11 interface.
Current BSSID and channel are now reported in the 802.11 status
display, if supported by the interface.
Above changes from David Young <dyoung@ojctech.com>, with some slight
changes by me (use ethers(3) functions rather than hand-parsing/printing
the 802.11 address).
Document bssid/-bssid/channel, and clean up markup of parentheticals
in the manual page.
and exit.
Previously, combinations would produce unintended results, such as
deleting the primary IP on an interface, instead of deleting an specified
alias.
Currently, only Aironet ("an") driver/card can be used.

network interfaces. This works by pre-computing the pseudo-header
checksum and caching it, delaying the actual checksum to ip_output()
if the hardware cannot perform the sum for us. In-bound checksums
can either be fully-checked by hardware, or summed up for final
verification by software. This method was modeled after how this
is done in FreeBSD, although the code is significantly different in
most places.
We don't delay checksums for IPv6/TCP, but we do take advantage of the
cached pseudo-header checksum.
Note: hardware-assisted checksumming defaults to "off". It is
enabled with ifconfig(8). See the manual page for details.
Implement hardware-assisted checksumming on the DP83820 Gigabit Ethernet,
3c90xB/3c90xC 10/100 Ethernet, and Alteon Tigon/Tigon2 Gigabit Ethernet.
u_int8_t array to struct ieee80211_nwid to prepend length field.
The length field is necessary because IEEE 802.11 spec doesn't prohibit
even '\0' for SSID.
Though the name and the value of SIOC... macro is unchanged, this change
breaks binary compatibility. The only affected userland program on the
tree is ifconfig(8).
As Jason suggested on tech-net, it is better than live with problems
since there are no releases for this ioctls yet.
a meaningful option.
- Don't captialize the word address or interface when it refers an arugment.
- Use .Ar macro for dest_address since it is not a keyword.
that gifconfig(8) would issue to configure tunnel endpoints. This
allows IP tunnel interfaces (`gif' right now, and `gre' later) to
be configured with ifconfig(8), and via /etc/ifconfig.<interface>.
Partially taken from similar changes in OpenBSD.
- Const poison the command functions a bit. We really need to clean
up the command function interface.
in_status() handles the whole inet address family. in_alias() handles
printout for single address (for both the primary address or an alias).
it is more consistent with, for example, the way at_status() is used.
rather a bug in the code (which is violating the C standard by casting
an unaligned pointer to a pointer with more strict alignment constraints).
Fix the code to not do such things. Fixes port-alpha/9494.
this is intentional - IPv6 assumes multiple addresses on an interface,
and it is not very safe to "delete" arbitrary one. -alias with
explicit IPv6 address works fine.
(i.e., 10baseT carrier/no carrier) of an interface from scripts
ifconfig -s <interface> will exit with a false status if the interface
reports its unconnected.
-s also works in conjunction with -l and -a, filtering out interfaces
which are reporting down.
Also, add -b (which shows only broadcast interfaces with -l and -a).
I find these options useful in network autoconfig scripts for mobile
systems.
code would hit the interface multiple times. Now, all media and media
options are gathered and processed at once, hitting the interface only
once (except to grab the currently selected media exactly once; there is
no way to avoid that).

The intent here is to allow cut'n'pasting of the output to a command
line, or allow easier automatic extraction from scripts, etc.
XXX Still at issue is what to do about non-0 media instances.
data structure is used, but a much saner matching mechanism is used, one
which allows greater ease in adding new types.
Also, rewrite the way media words are displayed. The status display now
looks like this:
bishop:thorpej 137$ ifconfig -m fxp0
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

This makes it more clear which media type (e.g. Ethernet) is currently
in-use, handy for devices such as the TI ThunderLAN which can also have
both Ethernet and Token Ring PHYs attached.
