If multiple threads are invoking "ifconfig XXX create" a race may occur

ifconfig(8): Attempt to render non-printable sequences w/ UTF-8 Environment

Currently ifconfig(8) only prints the hex representation of ssid names
with non-ASCII characters. Many modern terminals are able to properly render
non-ASCII characters. This change checks if the terminal charmap is UTF-8,
and if so, will render the characters, rather than the hex value.

This behavior is circumvented by running ifconfig(8) in a non-UTF8 locale;
e.g. C or POSIX.

It was pointed out by kp@ during the review that APs have the option to
broadcast whether their SSIDs may be interpreted as UTF-8. Ideally, we would
honor this and only attempt this behavior if it's so-broadcasted by the AP.

However, a sample survey showed that hostapd will advertise this if
indicated in config but it doesn't seem to be so common in the AP market, so
this would be effectively useless as we'll rarely know if the SSID should be
renderable as UTF-8.

Despite this, it was decided to be OK with this anyways- there's a
straightforward path to doing it the right way based on advertisement by AP
if we need to go that route, and one can revert to old behavior easily
enough at runtime if we get it wrong.

that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

ifconfig: set by default FCC regulatory domain for wireless interfaces.

Change default regulatory domain from DEBUG (no limitations;
exposes all device channels) to FCC; as a result, newly created wireless
interface with default settings will have less chances to violate
country-specific regulations.

This change will not affect drivers with pre-initialized regdomain
structure (currentry ath(4) and mwl(4)); in that case, the default
channel list must correspond to the default regdomain / country setting.

You can switch to another regdomain / country via corresponding
ifconfig(8) options; the driver must implement ic_getradiocaps()
method to restore full channel list.

Full country / regdomain list may be obtained via
'ifconfig <iface> list countries' command.

Example: change country to Germany:
ifconfig wlan0 down # all wlans on the device must be down
ifconfig wlan0 country DE
ifconfig wlan0 up
# wpa_supplicant(8), dhclient(8) etc

At the creation time:
ifconfig wlan0 create wlandev wpi0 country DE

This patch removes a check in ifconfig which disables HT/40 channels
on frequency bands with DFS. All Atheros chipsets >= AR9001 support
radar event detection on HT40 extension channels.

This should be a chipset specific item rather than enforced in the

In addition, it's irrelevant for STA mode, as the radar detection is
done by the access point, not the STA.

When requesting a scan and one is already in progess, e.g. while in scan

to associate to and there is none. Instead of always waiting for a
notification just do so if a new scan has been started. For both cases the
scan cache is used to report available networks even if the content might
not be fresh.

When doing a scan while being associated it is possible that the scan
is deferred for the time it takes to flush the TX queue. This work being

brought up, request a background scan by default. This behaviour is
already documented in manual page.

Implementation of the upcoming Wireless Mesh standard, 802.11s, on the
net80211 wireless stack. This work is based on the March 2009 D3.0 draft
standard. This standard is expected to become final next year.
This includes two main net80211 modules, ieee80211_mesh.c
which deals with peer link management, link metric calculation,
routing table control and mesh configuration and ieee80211_hwmp.c
which deals with the actually routing process on the mesh network.
HWMP is the mandatory routing protocol on by the mesh standard, but
others, such as RA-OLSR, can be implemented.

Authentication and encryption are not implemented.

There are several scripts under tools/tools/net80211/scripts that can be
used to test different mesh network topologies and they also teach you
how to setup a mesh vap (for the impatient: ifconfig wlan0 create
wlandev ... wlanmode mesh).

A new build option is available: IEEE80211_SUPPORT_MESH and it's enabled
by default on GENERIC kernels for i386, amd64, sparc64 and pc98.

Drivers that support mesh networks right now are: ath, ral and mwl.

More information at: http://wiki.freebsd.org/WifiMesh

Please note that this work is experimental. Also, please note that
bridging a mesh vap with another network interface is not yet supported.

Many thanks to the FreeBSD Foundation for sponsoring this project and to
Sam Leffler for his support.
Also, I would like to thank Gateworks Corporation for sending me a

Fixup handling of roaming and xmit parameters to support 1/2 and 1/4-width

o add 'q' mode flag for quarter-width channels
o rewrite rate parameter parsing to handle fractional values
o merge mode loops to eliminate ordering assumptions
o replace 0x80 with IEEE80211_RATE_MCS

Regulatory fixups:
o add missing channel flags for ECM, indoor, and outdoor constraints
o use HT capabilities to short-circuit HT20/HT40 channel construction
o rewrite 1/2 and 1/4 width channel handling yet again; previously
we assumed there was a full-width version of the channel in the
calibration table but that's not always true (e.g. for the Public
Safety Band), now we first check the calibration table for the
exact channel we want then fall back to the heuristics we used before
o fix HT channel construction; wasn't adjusting band edges for HT40
channel bandwidth requirements

Use %u instead of %zu when we intend to print integer constant.

include the channel list in list caps when -v is set; ieee channel
#'s are not available and we have to hack around the mapchan routine
but it lets us see the calibration table w/o forcing the debug regdomain

pritize the channel we display with list chans so that, among other
things, 1/2 and 1/4 width channels are hidden behind the full width
channel; this is needed because they are ordered such that they
appear after in the channel table

simplify display of 1/2 and 1/4 width channels

improve debug msgs for regdomain operations; print channel flags
symbolically so it's easier to identify channels and why they
are added (or not)

Fix 1/2 and 1/4 width channel handling:
o only include 1/2 and 1/4 width channels when they are specified in the
regulatory database description; previously we treated them as if they
were part of the band and blindly added them for 11a/g
o check the channel list returned in the devcaps to identify whether a
device supports 1/2 or 1/4 width channels on a band; this might be
better brought out as a capability bit to avoid filling the channel
list w/ 1/2 and 1/4 width channels but then cards that only support
these channels in a range of frequencies could not be described (though
right now we don't check frequency range only band)

Remove assumptions about the max # channels in ioctl's:
o change ioctl's that pass channel lists in/out to handle variable-size
arrays instead of a fixed (compile-time) value; we do this in a way
that maintains binary compatibility
o change ifconfig so all channel list data structures are now allocated
to hold MAXCHAN entries (1536); this, for example, allows the kernel
to return > IEEE80211_CHAN_MAX entries for calls like IEEE80211_IOC_DEVCAPS

Fix 1/2 and 1/4 width channel handling for non-GSM operation:

Add a new flag '-k' to ifconfig(8), indicating that it is alright to
print potentially sensitive keying material to stdout. With the new
802.11 support, ifconfig(8) is now capable of printing 802.11 keys,
and did by default for the root user, which is undesirable in some
environments. Now it will not print keying material unless requested
(and available to the user).

Fix special status reporting. Prior to the reorg there was
special-purpose code to display status for an interface for
state that was not address-oriented. This status reporting
was merged in to the address-oriented status reporting but
did not work for link address reporting (as discovered with
fwip interfaces). Correct this mis-merge and eliminate the
bogus kludge that was used for link-level address reporting.

o add an af_other_status method for an address family for
reporting status of things like media, vlan, etc.
o call the af_other_status methods after reporting address
status for an interface
o special-case link address status; when reporting all
status for an interface invoke it specially prior to
reporting af_other_status methods (since it requires the
sockaddr_dl that is passed in to status separately from
the rtmsg address state)
o correct the calling convention for link address status;
don't cast types, construct the proper parameter

This fixes ifconfig on fwip interfaces.

o accept deftxkey as a synonym for weptxkey since that is what is
printed for status (allows cut&paste)
o accept undef for the deftxkey/weptxkey so you can reset state

Overhaul to cleanup some of the tangled logic that's grown over the years.

o break per-address family support out into separate files
o modularize per-address family and functional operations using
a registration mechanism; this permits configuration according
to which files you include (but beware that order of the files
is important to insure backwards compatibility)
o many cleanups to eliminate incestuous behaviour, global variables,
and poor coding practices (still much more to fix)

The original motivation of this work was to support dynamic addition
of functionality based on the interface so we can eliminate the various
little control programs and so that vendors can distribute ifconfig
plugins that support their in-kernel code. That work is still to be
completed.

o Update 802.11 support for all the new net80211 functionality; some
of these operations (e.g. list *) may be better suited in a different
program

Fix an off-by-one error in the function used to input the ascii/hex strings.
Be a little bit more helpful in error messages.

add support for setting 802.11 rtsthreshold, transmit power,
and 11g protection mode

We want the length of the string, not the size of its pointer.

o add support for setting 128-bit WEP keys
o use IEEE80211_KEYBUF_SIZE instead of magic numbers
o distinguish between 40-, 104-, and 128-bit WEP keys when printing status

o update for new 802.11 support
o fix channel command so channel - does what the man page says

De-__P, use ansi function definitions

Some style(9) whitespace fixes and a correction to the copyright.

Fix bugs in the structure for rx_frame by making gap length one byte and
a packed array so sizeof work. This broke RFMON mode and passing
up 802.11 packets.

The Linux emulation code was derived from the open source Linux driver to
maintain compatibility.

LEAP support is added, hints from Richard Johnson. I've verified this
locally with PC350v42510.img firmware. More bug fixing from Marco to
fix long passwords.

Change DELAYs in flash part of driver to FLASH_DELAY which uses tsleep
so it doesn't look like your system died during a flash update.

Install header files in /usr/include/dev/an

Cleanup some ifmedia bugs add "Home" key mode to ifmedia and ancontrol.
This way you can manage 2 keys a little easier. Map the home mode into
key 5. Enhance ifconfig to dump the various configured SSIDs. I use
a bunch of different ones and roam between them. Use the syntax similar
to the WEP keys to deal with setting difference SSIDs.

Bump up up the Card capabilities RID since they added 2 bytes to it
in the latest firmware. Thankfully we changed it from a terminal
failure so the card still worked but the driver whined.
