1d0d8888af build: Make more library things common
We don't really need to duplicate more of this, so just
move the lib.rules include to the end and do more of the
stuff that's common anyway there.

f4b3d14e97 build: Make a common library build
Derive the library name from the directory name, and let each
library Makefile only declare the objects that are needed.

This reduces duplicate code for the ar call. While at it, also
pretty-print that call.

87098d3324 build: Put archive files into build/ folder too
This is something I hadn't previously done, but there are
cases where it's needed, e.g., building 'wlantest' and then
one of the tests/fuzzing/*/ projects, they use a different
configuration (fuzzing vs. not fuzzing).

Perhaps more importantly, this gets rid of the last thing
that was dumped into the source directories, apart from
the binaries themselves.

Note that due to the use of thin archives, this required
building with absolute paths.

722138cd25 build: Put object files into build/ folder
Instead of building in the source tree, put most object
files into the build/ folder at the root, and put each
thing that's being built into a separate folder.

This then allows us to build hostapd and wpa_supplicant
(or other combinations) without "make clean" inbetween.

For the tests keep the objects in place for now (and to
do that, add the build rule) so that we don't have to
rewrite all of that with $(call BUILDOBJS,...) which is
just noise there.

a28d127b1a AP: Reflect status code in SAE reflection attack test
When testing SAE reflection, the incoming commit may have the H2E status
code (126) or SAE-PK (127), but the test code in the AP was always
sending back status code 0. The STA would then reject the commit
response due to expecting H2E/SAE-PK status code.

Just reflect the incoming status code so the commit can be rejected
based on the SAE contents regardless of which variant of SAE was used.

debf3e2165 OCV: Work around for misbehaving STAs that indicate OCVC=1 without OCI
Some legacy stations copy previously reserved RSN capability bits,
including OCVC, in (Re)Association Request frames from the AP's RSNE but
do not indicate MFP capability and/or do not send OCI in RSN handshakes.
This is causing connection failures with such erroneous STAs.

To improve interoperability with such legacy STAs allow a workaround OCV
mode to be enabled to ignore OCVC=1 from the STA if it does not follow
OCV requirements in the first protected exchange. This covers cases
where a STA claims to have OCV capability, but it does not negotiate use
of management frame protection or does not include OCI in EAPOL Key msg
2/4, FT Reassociation Request frame, or FILS (Re)Association Reqest.

The previous behavior with ocv=1 is maintained, i.e., misbehaving STAs
are not allowed to connect. When the new workaround mode is enabled with
ocv=2, the AP considers STA as OCV capable on below criteria
- STA indicates both OCV and MFP capability
- STA sends OCI during connection attempt in a protected frame

Enabling this workaround mode reduced OCV protection to some extend
since it allows misbehavior to go through. As such, this should be
enabled only if interoperability with misbehaving STAs is needed.

cf3d260c39 DPP2: Fix hostapd crash setting global configurator params on chirp RX
When a Presence Announcement frame is received, a check is done to
ensure an ongoing auth is not in progress (!hapd->dpp_auth). A new DPP
auth is then initialized, however, when setting global configurator
params for it, the hapd->dpp_auth pointer is used which was earlier
confirmed as NULL, causing a crash in dpp_set_configurator params when
the pointer is dereferenced.

This only occurs when there are global DPP configurator params to be set
and the peer has no overriding configurator params. If no global DPP
configurator params exist, the call to dpp_set_configurator exits early
and the problem is not observed.

Fix by using the newly init'ed DPP auth structure for setting global
DPP configurator params.

e3ba0c4cd2 Do not start SA Query procedure without keys
The AP mode condition for initiating the SA Query procedure when
receiving a new (Re)Association Request frame used only association
state and MFP negotiation result without checking that the key exchange
has been completed. This can give rise to a corner case where the SA
Query procedure may get started after open association but before the
4-way handshake has been completed, resulting in open SA query frames
over the air.

Fix this by adding station authorized check in hostapd_notif_assoc() and
check_assoc_ies().

96e63008fb OWE: Do not add DH Params element in AssocResp with PMKSA caching
As per RFC 8110 (Opportunistic Wireless Encryption), if the AP has the
PMK identified by the PMKID and wishes to perform PMK caching, it will
include the PMKID in the Association Response frame RSNE but does not
include the Diffie-Hellman Parameter element.

This was already addressed for most cases with owe_process_assoc_req()
not setting sta->owe_ecdh in case PMKSA caching is used. However, it was
possible to an old STA entry to maintain the initial sta->owe_ecdh value
if reassociation back to the same AP was used to initiate the PMKSA
caching attempt. Cover that case by adding an explicit check for the
time when the Association Response frame is being generated.

d578e890eb OWE: Skip beacon update of transition BSS if it is not yet enabled
When a single hostapd process manages both the OWE and open BSS for
transition mode, owe_transition_ifname can be used to clone the
transition mode information (i.e., BSSID/SSID) automatically. When both
BSSs use ACS, the completion of ACS on the 1st BSS sets state to
HAPD_IFACE_ENABLED and the OWE transition mode information is updated
for all the other BSSs. However, the 2nd BSS is still in the ACS phase
and the beacon update messes up the state for AP startup and prevents
proper ACS competion.

If 2nd BSS is not yet enabled (e.g., in ACS), skip beacon update and
defer OWE transition information cloning until the BSS is enabled.
