rfkill was re-implemented on 2.6.31. We port it to
|
|
older kernels with a simple hack, just rename the
|
|
module as a new one rfkill_backport, and every
|
|
exported symbol gets redefined with a _backport
|
|
postfix through compat-2.6.31.h. The changes below
|
|
are the ones we could not do through compat-2.6.31.h
|
|
|
|
Do older kernels have /dev/rfkill ? I not then we can
|
|
just keep /dev/rfkill and not /dev/rfkill_backport.
|
|
|
|
Note that 2.6.31 added netdevice notifier upon interface
|
|
dev_open() which on cfg80211 will check if checks to see
|
|
if rfkill is enabled (or if the mode of operation is not
|
|
supported) on the cfg80211_netdev_notifier_call() and if
|
|
so deny bringing the interface up. This was added via
|
|
commit:
|
|
|
|

|
|
|
|
Since older kernels will not have the notifier call
|
|
on dev_open() if we *really want* to port this we could have
|
|
mac80211's subif_open() call :
|
|
|
|
ret = call_netdevice_notifiers(NETDEV_PRE_UP, dev);
|
|
ret = notifier_to_errno(ret);
|
|
if (ret)
|
|
return ret;
|
|
|
|
This would do the policing from within mac80211.
