One of supported code paths already allows this scenario. It is used if
driver doesn't report NL80211_ATTR_DEVICE_AP_SME and doesn't support
monitor interface. In such situation:
1) We don't quit if subscribing for WLAN_FC_STYPE_PROBE_REQ fails
2) We don't try subscribing for WLAN_FC_STYPE_ACTION
3) We fallback to AP SME mode after failing to create monitor interface
4) We don't quit if subscribing for WLAN_FC_STYPE_PROBE_REQ fails
Above scenario is used, e.g., with brcmfmac. As you can see - thanks to
events provided by cfg80211 - it's not really required to receive Probe
Request or action frames.
However, the previous implementation did not allow using hostapd with
drivers that:
1) Report NL80211_ATTR_DEVICE_AP_SME
2) Don't support subscribing for PROBE_REQ and/or ACTION frames
In case of using such a driver hostapd will cancel setup after failing
to subscribe for WLAN_FC_STYPE_ACTION. I noticed it after setting flag
WIPHY_FLAG_HAVE_AP_SME in brcmfmac driver for my experiments.

On systems that have multiple WLAN rfkill instances, the rfkill code
can become confused into thinking that the device was unblocked when
in fact it wasn't, because it only matches on the WLAN type.
Since it then stores the new (unblocked) state from the wrong rfkill
instance, it will never retry the failing IFF_UP operation and the
user has to toggle rfkill again, or otherwise intervene manually, in
this case to get back to operational state.
Fix this by using the existing (but unused) ifname argument when the
rfkill instance is created to match to a specific rfkill index only.
As a P2P Device interface does not have a netdev interface associated
with it, use the name of a sibling interface to initialize the rfkill
context for the P2P Device interface. For nl80211, as the wiphy index

When an AP interface it created, it is also setup and subscribes
for management frames etc. However, when the interface is added by
wpa_supplicant, setting up for AP operations is redundant because
it will be done by wpa_supplicant on wpa_drv_init() when setting
the interface mode to AP.
In addition, it may cause wpa_supplicant to fail initializing the

interface but the interface is already registered.

optional, and use it only when the interface is added by hostapd but not

This modifies the BSS selection routines to calculate SNR and estimated
throughput for each scan result and then use the estimated throughput as
a criteria for sorting the results. This extends the earlier design by
taking into account higher throughput rates if both the AP and local
device supports HT20, HT40, or VHT80. In addition, the maximum rate is
restricted based on SNR.
In practice, this gives significantly higher probability of selecting
HT/VHT APs when there are multiple BSSes in the same ESS and SNR is not

Commit 5a2a6de6a5 ('mesh: Make inactivity
timer configurable') has a problem on 32 bit systems. Setting
NL80211_MESHCONF_PLINK_TIMEOUT to 0xffffffff causes expiration of STA in
a minute by NL80211_CMD_DEL_STATION event. this is the kernel rule for
STA expiration:
(current jiffies) > (frame Rx jiffies + NL80211_MESHCONF_PLINK_TIMEOUT * 250)
On a 32 bit system, the right side could overflow and be unexpected
small value if NL80211_MESHCONF_PLINK_TIMEOUT is sufficiently large. STA
expiration occurs by this reason.
This patch solves the problem by disabling the STA expiration
functionality in mac80211. However, old kernel does not support
disabling it. If so, this patch sets mac80211 inactivity timer 60
seconds into future from the wpa_supplicant inactivity timer.

timer in wpa_supplicant. This commit fixes it also.

Commit 6c6678e7a4 ('nl80211: Make
br_ifindex available in i802_bss') did not cover the case where
i802_check_bridge() ends up creating the bridge interface. That left
bss->br_ifindex zero and prevented neighbor addition. Extend that
functionality to update br_ifindex once the bridge netdev has been
added.

The driver_test.c driver wrapper (-Dtest in wpa_supplicant and

Wi-Fi hardware. mac80211_hwsim-based tests have practically replaced all

Commit 97279d8d (after hostap-2.0) dropped frame events from foreign
addresses. Unfortunately this commit did not handle the case where the
interface's MAC address might be changed externally, which other
wpa_supplicant code already handled. This causes the driver to reject
any MLME event because the address from the event doesn't match the
stale address in the driver data.
Changing an interface's MAC address requires that the interface be
down, the change made, and then the interface brought back up. This
triggers an RTM_NEWLINK event which driver_nl80211.c can use to
re-read the MAC address of the interface.

Previously, extra connect/roam events were ignored when user space SME
was used to avoid confusing double events for association. However,
there was no matching code for ignoring auth/assoc events when using
driver SME. Such events would not normally show up since the driver SME
case would not generated them. However, when testing forced connect
command with force_connect_cmd=1 driver param, these events are
indicated.
Ignore the extra events in testing cases to make the hwsim test cases
match more closely the real code path for driver SME. In addition, this
resolves some test case failures where double association event could
end up causing a failure, e.g., when doing PMKSA caching in
pmksa_cache_oppurtunistic_connect.
