We generate the DBus error reply type from the errno only when
ap_start() was failing synchronously, now also send the errno through
the callbacks so that we can also return a specific DBus reply when
failing asynchronously. Thea AP autotest relies on receiving the
AlreadyExists DBus error.
Change ap_start to load all of the AP configuration from a struct
l_settings, moving the 6 or so parameters from struct ap_config members
to the l_settings groups and keys. This extends the ap profile concept
used for the DHCP settings. ap_start callers create the l_settings
object and fill the values in it or read the settings in from a file.
Since ap_setup_dhcp and ap_load_profile_and_dhcp no longer do the
settings file loading, they needed to be refactored and some issues were
fixed in their logic, e.g. l_dhcp_server_set_ip_address() was never
called when the "IP pool" was used. Also the IP pool was previously only
used if the ap->config->profile was NULL and this didn't match what the
docs said:
"If [IPv4].Address is not provided and no IP address is set on the
interface prior to calling StartProfile the IP pool will be used."
Pass the string IEs from the incoming STA association frames to
the user in the AP event data. I drop
ap_event_station_added_data.rsn_ie because that probably wasn't
going to ever be useful and the RSN IE is included in the .assoc_ies
array in any case.
Users can now start an AP from settings based on a profile
on disk. The only argument is the SSID which will be used to
lookup the profile. If no profile is found a NotFound error
will be returned. Any invalid profiles will result in an
Invalid return.
Add a "psk" setting to allow the user to pass the binary PSK directly
instead of generating it from the passphrase and the SSID. In that case
we'll only send the PSK to WSC enrollees.
This adds the API for putting the AP in Push Button mode, which we'll
need to P2P GO side but may be useful on its own too. A WSC IE is added
to our beacons and probe responses indicating whether the PBC mode is
active.
To limit the number of ap_start parameters, group basic AP config
parameters in the ap_config struct that is passed as a pointer and owned
by the ap_state.
Rather than have device.c manage the creation/removal of
AP/AdHoc interfaces this new event was introduced. Now
anyone can listen for device events and if the mode changes
handle accordingly. This fixes potential memory leaks
in WSC when switching modes as well.
Now, a user can setup an AP as follows:
- Set device "Mode" to ap (ap interface will appear on bus)
- call "Start()" on AP interface
Issuing "Stop()" on the AP interface will stop and cleanup
the internal AP structures, but the AP interface will remain
up. To shutdown completely the device Mode must be switched
back to station. If the AP interface is running, the Mode can
directly be switched to station without calling Stop; this
has the same effect and will take down the AP interface.
