This is a bit problematic change for number of test cases since there are various checks and operations depending on the exact SSID. Based on a quick test, almost 100 test cases fail because of that (see list below). If we want to get this included in hostap.git, it would likely be a good idea to make this more generic by allowing it to be run (as an optional functionality) as part of the local mac80211_hwsim test cases in addition to the remote test cases. That makes it quite a bit more convenient to verify full implications to the test cases. > diff --git a/tests/hwsim/hostapd.py b/tests/hwsim/hostapd.py > @@ -406,7 +406,12 @@ def add_ap(apdev, params, wait_enabled=True, no_enable=False, timeout=30): > - hapd.set(field, params[field]) > + if hostname is not None and field in ["ssid", "ssid2"]: > + import rutils > + prefix = rutils.RandomSsid.ssid_prefix > + hapd.set(field, prefix + params[field]) > + else: > + hapd.set(field, params[field]) That ssid2 part is problematic since the ssid2 value can start with the '"' and 'P"' prefixes. Neither of those cases would work correctly if this random prefix is added. The third option (hexdump) would work, but this ssid2 change would need more logic here to handle all possible cases. Adding any prefix to SSID would also need to take into account possibility of going beyond the 32 octet limit, i.e., the changes here should be conditional on there being sufficient room for the extra prefix. > diff --git a/tests/hwsim/wpasupplicant.py b/tests/hwsim/wpasupplicant.py > def connect(self, ssid=None, ssid2=None, **kwargs): > + prefix = "" > + if self.hostname is not None: > + import rutils > + prefix = rutils.RandomSsid.ssid_prefix > if ssid: > - self.set_network_quoted(id, "ssid", ssid) > + self.set_network_quoted(id, "ssid", prefix + ssid) > elif ssid2: > - self.set_network(id, "ssid", ssid2) > + self.set_network(id, "ssid", prefix + ssid2) > diff --git a/tests/remote/rutils.py b/tests/remote/rutils.py > +class RandomSsid(object): tests/hwsim/utils.py could be more useful location for this to allow the local test cases to be used to check this functionality as well.
