The way the removal of duplicated (one per frequency) BSS entries in the
cfg80211 scan results were removed in driver_nl80211_scan.c
bss_info_handler() depended on having the full scan results available to
allow iteration through the other entries. This is problematic for the
goal of being able to optimize memory allocations for scan result
fetching in a manner that would not build the full result buffer in
memory.
Move this duplicate removal into bss.c since it has sufficient
information available for doing the same determination of which one of
two BSS entries is more current.

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.

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.

This untangles the NL80211_CMD_GET_SURVEY handler loop from
NL80211_CMD_GET_SCAN processing so that the per-channel noise
information can be fetched with a common function to a local data
structure that can then be easily used to update individual scan results
(a single BSS) instead of having to go through a full set of scan
results. This is a step towards optimizing scan result fetching without
having to allocate memory for all entries at the same time.

Refactor the common parts of wired drivers code into a shared file, so
that they can be reused by other drivers. The macsec_qca driver already
contains a lot of code duplication from the wired driver, and the
macsec_linux driver would do the same. A structure to hold data common

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.

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.

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").
wpa_validate_wpa_ie() now explicitly checks for this condition to meet
this requirement instead of simply ignoring the MDE based on non-FT AKM.

cfg80211 rejects the scans issued with random MAC address if the STA is
in connected state. This resulted in failures when using MAC_RAND_SCAN
while connected (CTRL-EVENT-SCAN-FAILED ret=-95). Enable random MAC
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.
