150ee0c068 AP: Add an additional TPE element when needed
If the regulatory client EIRP PSD values advertised by an AP that is a
standard power AP or indoor standard power AP are insufficient to ensure
that regulatory client limits on total EIRP are always met for all
transmission bandwidths within the bandwidth of the AP’s BSS, the AP
shall also send a TPE element in Beacon and Probe Response frames as
that depicts the regulatory client EIRP limit.

Add support for this.

c8dd70cfb1 Fix Multiple BSSID element length calculation
Currently while deciding to create a new Multiple BSSID element based on
the condition when the length reaches 255, the length value being used
is the total element length (including the length of the Element ID and
Length fields as well). However, the value in the length field denotes
the number of octets following it and excluding itself. Hence including
the total length is wrong. This leads to incorrect count of Multiple
BSSID elements.

And while filling the data, the length is considered porperly as it
should be hence we are filling more data in a single go and all data is
filled in MBSSID count which is less than originally calculated. This
ultimately leads to incorrect length calculation during nla_put() and
setting the beacon to the driver fails while putting the Multiple BSSID
element data into the netlink socket buffer.

Fix this issue by considering the length excluding the Element ID and
Length field sizes.

This is a step towards cleaning up all the workarounds that have showed

removes use of the separate registration of process_bss_event() as
NL_CB_VALID for the individual commands since the use of the appropriate
cb (i.e., the one from nl80211_init_bss() in these cases) will already
point to the correct handler.

2ab56694f6 Split ap_sta_set_authorized() into two steps
This function is both updating the hostapd-internal sta->flags value and
sending out the AP-STA-CONNECTED control interface message. When
authorizing a STA, the call to this function is followed by a driver
command to update the flags of the STA entry in the driver. That has a
race condition at least for UML time-travel since the AP-STA-CONNECTED
event is used as a message to wait for before running a connectivity
test or some other operation that depends on the data connection being
in working condition.

Split the function into two steps so that the driver STA entry update
can be done between those two steps for the cases where it matters for
the race condition. In other words, send the AP-STA-CONNECTED message
only after having authorized the STA in the driver.
