This allows bgscan modules to use more information to decide on when
to perform background scans. bgscan_simple can now change between
short and long background scan intervals based on signal strength
and in addition, it can trigger immediate scans when the signal
strength is detected to be dropping.
bgscan_simple takes following parameters now:
short interval:signal strength threshold:long interval
For example:
bgscan="simple:30:-45:300"
This can be used to limit which frequencies are considered when
selecting a BSS. This is somewhat similar to scan_freq, but will
also affect any scan results regardless of which program triggered
the scan.
Must update sm->pairwise when fetching PMK-R1 SA.
Add a workaround for drivers that cannot set keys before association
(e.g., cfg80211/mac80211): retry PTK configuration after association.
If the PTK configuration prior to association fails, allow reassociation
attempt to continue and configure PTK after association. This is a
workaround for drivers that do not allow PTK to be configured before
association (e.g., current cfg80211/mac80211).
This attribute is supposed to indicate which methods the AP supports as
an Enrollee for adding external Registrars. It was left to 0 when the
AP code did not yet support external Registrars and was forgotten when
the ER support was added.
Need to kill the monitor process before running detach command on
the monitor connection to avoid race where the monitor process may
end up getting the detach command result.
Previously, this was only done with userspace MLME (i.e., driver_test.c);
now, driver_nl80211.c can deliver the FT Action Response (FT-over-DS)
for processing. The reassociation after successful FT Action frame
exchange is not yet implemented.

This patch solves this issue.
This is a step in adding FT support with nl80211-based drivers.
driver_nl80211.c is now registering to handle the FT Action frames
and is able to transmit FT Request frame. Received FT Action frames
are not yet indicated as driver events.
This is needed to fix PTK derivation to use correct length. Previously,
64-octet PTK may have been derived if the authenticator did not already
have a STA entry. Now, the correct pairwise cipher suite is learned when
then PMK-R1 SA is received.
This was not supposed to have duplicate value with WPA_AUTH_ALG_LEAP.
The previous version was unable to set FT as the authentication
algorithm with nl80211.
With this patch, a client gets kicked out of the last BSS it was
attached to, when it is associating to a different one.
While mac80211 does allow a station to be present on multiple bss
interfaces, this does seem to cause problems both for the stack
and for hostapd.
This patch allows the nl80211 driver to create its own per-bss context
and pass it to the drv_priv pointer of the hostapd bss state.
With this and the following patch, stations can associate to and switch
between multiple BSS interfaces of a single wiphy.
This obsoletes a few instances of passing ifname to a callback, those
can be removed in a separate patch.
It might also be useful to move more fields from the driver data to the
per-bss data structure in the future.
