d3c43e5855 privsep: Fix scan result fetching with Beacon frame IEs
wpa_priv did not yet support Beacon frame IEs (res->beacon_ie_len) which
resulted in invalid scan data being accepted in driver_privsep.c. Add
support for res->beacon_ie_len and also fix the validation step to take
this new variable length field into account.

e0641772a3 wpa_priv: Use fromlen instead sizeof(struct sockaddr_un)
This gets rid of some dependencies on how extra octets at the end of the
struct sockaddr_un get "uninitialized" consistently by only using the
exact length of the address data from the recvfrom() call. This resolves
number of valgrind warnings about use of uninitialized memory.

bf88401d23 Add support to abort vendor scan
This commit enhances the existing implementation of abort scan to also
abort concurrent active vendor scans. This is achieved by passing the
the scan_cookie to the driver interface with the intention to abort
the specific scan request. This scan_cookie is returned from the driver
interface when the scan request is scheduled.

This scan_cookie is 0 if the scan is triggered through the upstream
cfg80211 interface. Thus, the scan_cookie is used to determine whether
to abort the cfg80211 or vendor scan request.

Also, the previous implementation of relying on scan_work/p2p_scan_work
for the active work to trigger the abort scan is enhanced to check for
the started state of either of these work operations. This should also
help to abort the concurrent active scan/p2p-scan operations.

47d74bf010 Add MGMT_RX_PROCESS test command for hostapd
This makes it easier to write hwsim test cases to verify management
frame processing sequences with dropped or modified frames. When
ext_mgmt_frame_handling is used, this new command can be used to request
hostapd to process a received a management frame, e.g., based on
information reported in the MGMT-RX events.

This is more or less identical to the earlier wpa_supplicant commit
4de70e2330 ('Add MGMT_RX_PROCESS test
command for wpa_supplicant'), but for hostapd.

2ab09656ae AP: Do not drop STA entry if PMF is used with full AP client state
This fixes a regression from commit
bb598c3bdd ('AP: Add support for full
station state'). That commit added code to remove and re-add the kernel
STA entry when processing Authentication frames with a driver that
advertises support for full AP client state. That resulted in bypassing
PMF protections for unprotected Authentication frames with such drivers
since the TK was lost in this operation.

It is simplest to skip the STA entry clearing in this type of case
completely to leave the TK in place and to process the new
authentication exchange otherwise normally. This matches the behavior
used with the drivers that do not implement full AP client state.

IEEE Std 802.11-2012, 12.4.2 states that if an MDE is present in an
(Re)Association Request frame but the RSNE uses a non-FT AKM suite, the
AP shall reject the association using status code 43 ("Invalid AKMP").

this requirement instead of simply ignoring the MDE based on non-FT AKM.

346b333d9a Use random MAC address for scanning only in non-connected state
cfg80211 rejects the scans issued with random MAC address if the STA is

address functionality only if the STA is not in connected state to avoid
this. The real MAC address of the STA is already revealed in the
association, so this is an acceptable fallback mechanism for now.
