Wireless monitor
|
|
================
|
|
|
|
Netlink monitor interface is created if it does not exist
|
|
|
|
The iwmon utility automates netlink monitor creation by by using RTNL
|
|
to find an existing netlink monitor interface, and in case it does not
|
|
exist, create a new one. By default the netlink monitor interface is
|
|
named 'nlmon'. Another name can be given with the '--interface'
|
|
command line option.
|
|
|
|
Once iwmon terminates, the netlink monitor interface is removed (in
|
|
case iwmon created it).

HWSIM
|
|
=====
|
|
|
|
The radio id from kernel mac80211_hwsim module is parsed properly in
|
|
hwsim. The radio id is not returned as HWSIM_ATTR_RADIO_ID but instead
|
|
it is returned in error message. If the error code > 0, then that means
|
|
the radio id. If the error code < 0, then that indicates a real error.
|
|
|
|
The hwsim uses new HWSIM_ATTR_DESTROY_RADIO_ON_CLOSE flag attribute to
|
|
tell the kernel that when the hwsim process dies, the radios it created
|
|
should be removed. For testing tools it is beneficial if the newly
|
|
created radio could be bound to the lifetime of the netlink socket.
|
|
Alternatively, using the hwsim '-k (--keep)' command line option instructs
|
|
hwsim to not destroy the created radio automatically.
