A recent change checked the return value of ie_parse_rsne_from_data
inside the ptk 1/4 handler. This seemed safe, but actually caused
the eapol unit test to fail.
The reason was because eapol was parsing the IEs assuming they were
an RSN, when they could be a WPA IE (WPA1 not WPA2). The WPA case
does not end up using the rsn_info at all, so having rsn_info
uninitialized did not pose a problem. After adding the return value
check it was found this fails every time for WPA1.
Since the rsn_info is not needed for WPA1 we can only do the RSN
parse for WPA2 and leave rsn_info uninitialized.
The intent here was to validate that the frequency is a multiple of 5
and lies in a certain range. Somehow the channel was checked for being
a multiple of 5 instead.
The logic here intended to check whether all required attributes were
available. However, it set the parse_error to true instead of
have_required to false as intended.
Replace uses of strcpy by the safer l_strlcpy. Note that both of these
functions can only be called with a buffer of max 253 bytes (the
identity string), so this is purely a precautionary measure.
Technically there's no problem here as l_queue_remove does not
dereference the pointer. Still, it confuses certain static analysis
tools in the current form. Reordering this will not change the behavior
at all.
This was refactored to set the mtu via __eap_set_config rather than
passing the MTU into eap_init. This makes eap work in a similar fashion
as eapol (i.e. __eapol_set_config).
If __eap_set_config is not used, the MTU will be set to 1020, which is
the same as previously passing 0 to eap_init.
Since iwd_modules_init is now defered until nl80211_appeared, we can
assume the nl80211 object is available. This removes the need for
netdev_set_nl80211 completely.
In preparation for integrating IWD_MODULE into modules which require
nl80211 we move the module init into the nl80211_appeared callback.
This will guarentee that the nl80211 is available during module init
and allow modules to get their own copy of nl80211 rather than needing
a set function (e.g. netdev_set_nl80211).
Since the dbus name request callback happens before this as well any
dbus module can also use IWD_MODULE and simply assume the dbus object
is ready.
plugin_init was also deferred to nl80211_appeared since some plugins
depend on modules being initialized.
Converts agent into an IWD module. This removes the dbus dependency
on agent. Since dbus is initialized very early we can assume
dbus_get_bus is going to return a valid object.
