af9d8c758d tests: Use proper temp files for dynamically created config
Replace the hardcoded /tmp filenames for generated ACL and BSS
configuration files with proper temporary files from tempfile.mkstemp()
to avoid conflicts with existing files or with parallel uses. Remove ACL
files from the local directory at the end of each test case. BSS files
are currently left behind, but can be cleaned up separately if needed
for non-VM testing (VM testing has those on ramdrive so they get dropped
automatically at the end) and for remote devices.

bdff1be152 tests: Extend wpas_ctrl_bssid_filter for remote testing
When this test case is ran in remote test environment, there could be
additional APs in scan results after bssid_filter has been disabled.
That breaks the check on SCAN_RESULTS output. Extend this to cover the
remote testing case by using bssid_filter with both known APs listed
instead of full wildcard.

4b04223f24 hostapd: Replace UDP ctrl_iface global cookies with per-instance ones
The cookie values for UDP control interface commands was defined as a
static global array. This did not allow multi-BSS test cases to be
executed with UDP control interface. For example, after
    hapd1 = hostapd.add_bss(apdev[0], ifname1, 'bss-1.conf')
    hapd2 = hostapd.add_bss(apdev[0], ifname2, 'bss-2.conf')

hapd1->ping() did not work.

Move those cookie values to per-instance location in struct
hapd_interfaces and struct hostapd_data to fix this.

Some hostapd test cases use configuration files, e.g., ACLs in BSS
configuration. When executing remote tests (udp), we have to first send
these configuration files to the appropriate remote device. The new
send_file() helper can be used for that.

12fb9698ab Use IFNAME= prefix for global UDP control interface events
There does not seem to be a good reason for using the different IFACE=
prefix on the UDP control interface. This got added when the UDP
interface in wpa_supplicant was extended in commit f0e5d3b5c6
("wpa_supplicant: Share attach/detach/send UDP ctrl_iface functions")
and that was then extended to hostapd in commit e920805685 ("hostapd:
Extend global control interface notifications").

Replace the IFACE= prefix in UDP case with IFNAME= to be consistent with
the UNIX domain socket based control interface.

This fixes a problem when at least one test case fail (hapd_ctrl_sta)
when remote/udp used. This also fixes test_connectivity().

1f90a49d02 STA: Allow PTK rekeying without Ext KeyID to be disabled as a workaround
Rekeying a pairwise key using only keyid 0 (PTK0 rekey) has many broken
implementations and should be avoided when using or interacting with
one. The effects can be triggered by either end of the connection and
range from hardly noticeable disconnects over long connection freezes up
to leaking clear text MPDUs.

To allow affected users to mitigate the issues, add a new configuration
option "wpa_deny_ptk0_rekey" to replace all PTK0 rekeys with fast
reconnects.

7b26238d46 Do not skip MBO PMF check with the WPS special case WPA check exception
The MBO PMF check for AP SME in the driver case was added into a
location that is skipped for WPS processing. That was not really the
correct place for this since the skip_wpa_check label was supposed to
remain immediately following the WPA checks. While this does not really
have much of a practical impact, move the check around so that the
skip_wpa_check label remains where it is supposed to be.

640d59942b Fix location of MDE and RSNXE in Beacon and Probe Response frames
Split the IEs from WPA authenticator state machine into separately added
IEs so that the exact location between these and other elements can be
controlled. This fixes the location of MDE and RSNXE in Beacon and Probe
Response frames. In addition, this swaps the order of BSS Load and RM
Enabled Capabilities elements in Beacon frames to get them into the
correct order (which was already used for Probe Response frames).
Furthermore, this fixes the buffer end checks for couple of elements to
make the implementation more consistent (though, in practice, there is
no impact from this since the old size limit was smaller than needed,
but still sufficiently large to have room for these).

dd74ddd0df nl80211: Handle AKM suite selectors for AP configuration
Previously only couple of AKM suite selectors were converted into
NL80211_ATTR_AKM_SUITES. Add rest of the AKM suites here. However, since
the current kernel interface has a very small limit
(NL80211_MAX_NR_AKM_SUITES = 2), add the attribute only when no more
than that limit entries are included. cfg80211 would reject the command
with any more entries listed.

This needs to be extended in cfg80211/nl80211 in a backwards compatible
manner, so this seems to be the best that can be done for now in user
space. Many drivers do not use this attribute, so must not reject the
configuration completely when larger number of AKM suites is configured.
Such cases may not work properly with drivers that depend on
NL80211_ATTR_AKM_SUITES value.
