.Nd standard interface to IEEE 802.11 devices
|
||||||
|
.Sh SYNOPSIS
|
||||||
|
.Fd #include <net/if_ieee80211.h>
|
||||||
|
.Sh DESCRIPTION
|
||||||
|
This section describes the interface standard interface to configuration
|
||||||
|
and status information on IEEE 802.11 devices. Most devices support
|
||||||
|
options not configurable by this interface. They must be set by their
|
||||||
|
respective, specific control program. The interface is via one
|
||||||
|
of the following
|
||||||
|
.Xr ioctl 2
|
||||||
|
calls on a socket:
|
||||||
|
.Bl -tag -width SIOCG80211
|
||||||
|
.It Dv SIOCG80211
|
||||||
|
Get configuration or status information.
|
||||||
|
.It Dv SIOCS80211
|
||||||
|
Set configuration information.
|
||||||
|
.El
|
||||||
|
These requests are made via a modified
|
||||||
|
.Ar ifreq
|
||||||
|
structure. This structure is defined as follows:
|
||||||
|
.Bd -literal
|
||||||
|
struct ieee80211req {
|
||||||
|
char i_name[IFNAMSIZ]; /* if_name, e.g. "wi0" */
|
||||||
|
u_int16_t i_type; /* req type */
|
||||||
|
int16_t i_val; /* Index or simple value */
|
||||||
|
int16_t i_len; /* Index or simple value */
|
||||||
|
void *i_data; /* Extra data */
|
||||||
|
};
|
||||||
|
.Ed
|
||||||
|
.Pp
|
||||||
|
For
|
||||||
|
.Dv SIOCG80211
|
||||||
|
the following values of
|
||||||
|
.Ar i_type
|
||||||
|
are valid:
|
||||||
|
.Bl -tag -width IEEE80211_IOC_POWERSAVESLEEP
|
||||||
|
.It Dv IEEE80211_IOC_SSID
|
||||||
|
Returns the requested SSID by copying it into the buffer pointed to by
|
||||||
|
.Ar i_data
|
||||||
|
and setting
|
||||||
|
.Ar i_len
|
||||||
|
to the length. If
|
||||||
|
.Ar i_val
|
||||||
|
is >= 0 then the request refers to the configured value for that slot.
|
||||||
|
Generally, 0 is the only valid value, but some interfaces support more
|
||||||
|
SSIDs. If
|
||||||
|
.Ar i_val
|
||||||
|
is -1 then the request refers to the currently active value.
|
||||||
|
.It Dv IEEE80211_IOC_NUMSSIDS
|
||||||
|
Returns the number of SSIDs this card supports. In most cases, this is
|
||||||
|
1, but some devices such as
|
||||||
|
.Xr an 4
|
||||||
|
support more.
|
||||||
|
.It Dv IEEE80211_IOC_WEP
|
||||||
|
Returns the current WEP status in
|
||||||
|
.Ar i_val .
|
||||||
|
Valid values are
|
||||||
|
.Dv IEEE80211_WEP_NOSUP ,
|
||||||
|
.Dv IEEE80211_WEP_ON ,
|
||||||
|
.Dv IEEE80211_WEP_OFF ,
|
||||||
|
and
|
||||||
|
.Dv IEEE80211_WEP_MIXED .
|
||||||
|
Respectively, these values mean unsupported, mandatory for all devices,
|
||||||
|
off, and on, but not required for all devices.
|
||||||
|
.It Dv IEEE80211_IOC_WEPKEY
|
||||||
|
Returns the requested WEP key via
|
||||||
|
.Ar i_data
|
||||||
|
and it's length via
|
||||||
|
.Ar i_len .
|
||||||
|
If the device does not support returning the WEP key or the user is not
|
||||||
|
root then the key may be returned as all zeros. Technically this is a
|
||||||
|
valid key, but it's the kind of key an idiot would put on his luggage so
|
||||||
|
we use it as a special value. Generally, only four WEP keys are
|
||||||
|
allowed, but some devices support more. If so, the first four (0-3) are
|
||||||
|
the standard keys stored in volatile storage and the others are device
|
||||||
|
specific.
|
||||||
|
.It Dv IEEE80211_IOC_NUMWEPKEYS
|
||||||
|
Returns the number of WEP keys supported by this device, generally 4.
|
||||||
|
A device that does not support WEP may either report 0 or simply return
|
||||||
|
.Dv EINVAL .
|
||||||
|
.It Dv IEEE80211_IOC_WEPTXKEY
|
||||||
|
Returns the WEP key used for transmission.
|
||||||
|
.It Dv IEEE80211_IOC_AUTHMODE
|
||||||
|
Returns the current authentication mode in
|
||||||
|
.Ar i_val .
|
||||||
|
Valid values are
|
||||||
|
.Dv IEEE80211_AUTH_NONE ,
|
||||||
|
.Dv IEEE80211_AUTH_OPEN ,
|
||||||
|
and
|
||||||
|
.Dv IEEE80211_AUTH_SHARED .
|
||||||
|
.It Dv IEEE80211_IOC_STATIONNAME
|
||||||
|
Returns the station name via
|
||||||
|
.Ar i_data
|
||||||
|
and its length via
|
||||||
|
.Ar i_len .
|
||||||
|
While all known devices seem to support this is some way or another,
|
||||||
|
they all do it differently and it appears to not have anything to do
|
||||||
|
with the actual IEEE 802.11 standard so making up an answer may be
|
||||||
|
necessary for future devices.
|
||||||
|
.It Dv IEEE80211_IOC_CHANNEL
|
||||||
|
Returns the current direct sequence spread spectrum channel in use.
|
||||||
|
.It Dv IEEE80211_IOC_POWERSAVE
|
||||||
|
Returns the current powersaving mode. Valid values are
|
||||||
|
.Dv IEEE80211_POWERSAVE_NOSUP ,
|
||||||
|
.Dv IEEE80211_POWERSAVE_OFF ,
|
||||||
|
.Dv IEEE80211_POWERSAVE_ON ,
|
||||||
|
.Dv IEEE80211_POWERSAVE_CAM ,
|
||||||
|
.Dv IEEE80211_POWERSAVE_PSP ,
|
||||||
|
and
|
||||||
|
.Dv IEEE80211_POWERSAVE_PSP_CAM .
|
||||||
|
Currently,
|
||||||
|
.Dv IEEE80211_POWERSAVE_ON
|
||||||
|
is defined to be equal to
|
||||||
|
.Dv IEEE80211_POWERSAVE_CAM ,
|
||||||
|
but this may be incorrect.
|
||||||
|
.It Dv IEEE80211_IOC_POWERSAVESLEEP
|
||||||
|
Returns the powersave sleep time in msec in
|
||||||
|
.Ar i_val .
|
||||||
|
.El
|
||||||
|
.Pp
|
||||||
|
For
|
||||||
|
.Dv SIOCS80211
|
||||||
|
the following values of
|
||||||
|
.Ar i_type
|
||||||
|
are valid:
|
||||||
|
.Bl -tag -width IEEE80211_IOC_POWERSAVESLEEP
|
||||||
|
.It Dv IEEE80211_IOC_SSID
|
||||||
|
Set the desired SSID for infrastructure and ad-hoc modes to value given
|
||||||
|
by
|
||||||
|
.Ar i_data
|
||||||
|
and
|
||||||
|
.Ar i_len .
|
||||||
|
The length should be no longer then 32 characters.
|
||||||
|
.It Dv IEEE80211_IOC_WEP
|
||||||
|
Set the current WEP mode to the value given in
|
||||||
|
.Ar i_val .
|
||||||
|
Valid values are the same as those for this value above. Devices which
|
||||||
|
do not support all modes may choose to either return
|
||||||
|
.Dv EINVAL
|
||||||
|
or choose a reasonable alternate (supported) setting.
|
||||||
|
.It Dv IEEE80211_IOC_WEPKEY
|
||||||
|
Set the WEP key indicated by
|
||||||
|
.Ar i_val
|
||||||
|
to the value given by
|
||||||
|
.Ar i_data
|
||||||
|
and
|
||||||
|
.Ar i_len .
|
||||||
|
Generally, valid values of
|
||||||
|
.Ar i_len
|
||||||
|
are 0, 5, and 13 though not all devices with WEP support have support
|
||||||
|
for 13-byte keys.
|
||||||
|
.It Dv IEEE80211_IOC_WEPTXKEY
|
||||||
|
Set the WEP key used for transmission to the value in
|
||||||
|
.Ar i_val .
|
||||||
|
Not all values which are valid for setting keys may be valid for setting
|
||||||
|
transmit keys due to strange device interfaces.
|
||||||
|
.It Dv IEEE80211_IOC_AUTHMODE
|
||||||
|
Set the current authorization mode to the value given in
|
||||||
|
.Ar i_val .
|
||||||
|
Valid values are given above. No all devices support this.
|
||||||
|
.It Dv IEEE80211_IOC_STATIONNAME
|
||||||
|
Set the station name to the value given by
|
||||||
|
.Ar i_data
|
||||||
|
and
|
||||||
|
.Ar i_len .
|
||||||
|
The standard does not appear to deal with this feature so the range of
|
||||||
|
valid values may vary from device to device.
|
||||||
|
.It Dv IEEE80211_IOC_CHANNEL
|
||||||
|
Set the desired ad-hoc channel to the value given by
|
||||||
|
.Ar i_val .
|
||||||
|
On some devices this has an impact on infrastructure mode as well.
|
||||||
|
Valid values are 1-14, but 0 should be allowed and should return the
|
||||||
|
device to the default value. May devices support this directly by
|
||||||
|
converting any invalid value to the default value.
|
||||||
|
.It Dv IEEE80211_IOC_POWERSAVE
|
||||||
|
Set the current powersaving mode to the value given in
|
||||||
|
.Ar i_val .
|
||||||
|
Valid values are the same as those for this value above. Devices which
|
||||||
|
do not support all modes may choose to either return
|
||||||
|
.Dv EINVAL
|
||||||
|
or choose a reasonable alternate (supported) setting. Most devices only
|
||||||
|
support CAM mode.
|
||||||
|
.It Dv IEEE80211_IOC_POWERSAVESLEEP
|
||||||
|
Set the powersave sleep time in msec to the value in
|
||||||
|
.Ar i_val .
