If bssid is unspecified, the current scan code will usually fire off an

WPA/RSN IE from user space). mac80211-based drivers allow any AKM to be

Remove the unnecessary validation step in cfg80211 to allow drivers to

advertising supported AKMs, but that would not be very effective unless

iwlagn: fix dangling scan request
If iwl_scan_initiate() fails for any reason,
priv->scan_request and priv->scan_vif are left
dangling. This can lead to a crash later when
iwl_bg_scan_completed() tries to run a pending
scan request.
In practice, this seems to be very rare due to
the STATUS_SCANNING check earlier. That check,
however, is wrong -- it should allow a scan to
be queued when a reset/roc scan is going on.
When a normal scan is already going on, a new
one can't be issued by mac80211, so that code
can be removed completely. I introduced this
bug when adding off-channel support in commit

iwlagn: do not use interruptible waits
Since the dawn of its time, iwlwifi has used
interruptible waits to wait for synchronous
commands and firmware loading.
This leads to "interesting" bugs, because it
can't actually handle the interruptions; for
example when a command sending is interrupted
it will assume the command completed fully,
and then leave it pending, which leads to all
kinds of trouble when the command finishes
later.
Since there's no easy way to gracefully deal
with interruptions, fix the driver to not use
interruptible waits.

Bluetooth: Require authentication if MITM protection is requested
The HIGH security level requires a 16 digit pin code for non-SSP
bondings. Sometimes this requirement is not acceptable and we still
want protection againts MITM attacks (which is something that the
MEDIUM security level doesn't provide), for that we should allow
another way to request authentication without using the HIGH security
level.
