Every wifi-iface gets an option 'multi_ap'. For APs, its value can be 0 (multi-AP support disabled), 1 (backhaul AP), 2 (fronthaul AP), or 3 (fronthaul + backhaul AP). For STAs, it can be 0 (not a backhaul STA) or 1 (backhaul STA, can only associate with backhaul AP). Also add new optional parameter to wps_start ubus call of wpa_supplicant to indicate that a Multi-AP backhaul link is required.

Subject: [PATCH] multi_ap: don't reject backhaul STA on fronhaul BSS
|
|
|
|
The Multi-AP specification only specifies that information elements have
|
|
to be added to the association requests and responses; it doesn't
|
|
specify anything about what should be done in case they are missing.
|
|
Currently, we reject non-backhaul associations on a backhaul-only BSS,
|
|
and non-fronthaul associations on a fronthaul-only BSS.
|
|
|
|
However, this makes WPS fail when fronthaul and backhaul are separate
|
|
SSIDs. Indeed, WPS for the backhaul link is performed on the *fronthaul*
|
|
SSID. Thus, the association request used for WPS *will* contain the
|
|
Multi-AP IE indicating a backhaul STA. Rejecting that association makes
|
|
WPS fail.
|
|
|
|
Therefore, accept a multi-AP backhaul STA association request on a
|
|
fronthaul-only BSS. Still issue a warning about it, but only at level
|
|
DEBUG intead of INFO. Also change the condition checking to make it
|
|
clearer.
|
|
|
|
While we're at it, also fix the handling of unexpected bits in the
|
|
Multi-AP IE. 4 bits are reserved in the specification, so these
|
|
certainly have to be ignored. The specification also doesn't say that
|
|
setting one of the other bits is not allowed. Therefore, only report
|
|
unexpected values in the Multi-AP IE, don't reject because of it.
|
|
Note that a malformed IE (containing more than one byte) still triggers
|
|
a rejection.
