3fdaaa8fc4 Throttle control interface event message bursts
Some operations like a new scan result processing can result in large
number of wpa_supplicant control interface messages being generated.
Especially with multiple control interface monitors, this could result
in hitting the output queue length maximum and event messages getting
dropped. In worst case, that could even result in hitting ten
consecutive sendto() errors which could result in an attached monitor
socket getting detached.

Avoid this type of issues by throttling monitor event transmission based
on the output queue length. If more than half of the maximum send buffer
is used, postpone sending of following event messages until the pending
output queue has dropped below the limit.

7d82170aba Set channel and operating class in hostapd_fill_csa_settings()
The CSA channel and operating class values need to be set for all types
of channel switch (i.e., either if it's triggered by the control
interfaces or due to the GO-follows-STA flow). To do so, move the code
that sets them from the GO-follows-STA flow to the more generic
hostapd_fill_csa_settings() function.

d308a44fcc Use ieee80211_freq_to_chan() when getting segment indices
The hostapd_hw_get_channel() function can't be used to convert center
frequencies to channel numbers, because the hw mode lists don't have all
the center frequencies. The hw mode lists have the main channel
frequencies and flags to indicate the channel topography.

For instance, channel 5805 with VHT80- has the channel center frequency
segment 0 at 5775. This segment is only indicated indirectly in the hw
mode list by the HOSTAPD_CHAN_VHT_50_30 flag. The hw mode list doesn't
have any elements with frequency 5775 to allow the conversion to a
channel number. Thus, we need to use ieee80211_freq_to_chan() instead.

23dcb302eb P2P: Relax wpas_p2p_init_go_params() for P2P GO CSA
wpas_p2p_move_go_csa() uses wpas_p2p_init_p2p_params() to select the
frequency to move to. However, it is possible that all the channels are
already used, so the selection of a new frequency would fail, although
the frequency used by the P2P GO should not be considered as used if it
is the only one using it.

To overcome this, allow the frequency selection to continue even if all
the frequencies are in use, but the frequency used by the P2P GO is not
used by any station interface.

ad00d64e7d Fix TK configuration to the driver in EAPOL-Key 3/4 retry case
Commit 7d711541dc ('Clear TK part of PTK
after driver key configuration') started clearing TK from memory
immediately after having configured it to the driver when processing
EAPOL-Key message 3/4. While this covered the most common case, it did
not take into account the possibility of the authenticator having to
retry EAPOL-Key message 3/4 in case the first EAPOL-Key message 4/4
response is lost. That case ended up trying to reinstall the same TK to
the driver, but the key was not available anymore.

Fix the EAPOL-Key message 3/4 retry case by configuring TK to the driver
only once. There was no need to try to set the same key after each
EAPOL-Key message 3/4 since TK could not change. If actual PTK rekeying
is used, the new TK will be configured once when processing the new
EAPOL-Key message 3/4 for the first time.
