c2c4686228 Set NLA_F_NESTED flag with NL80211_ATTR_VENDOR_DATA conditionally
The newer kernel versions enforce strict netlink attribute policy
validation and will cause cfg80211 to reject vendor commands with
NL80211_ATTR_VENDOR_DATA if NLA_F_NESTED attribute is not set but
if the vendor command is expecting nested data within
NL80211_ATTR_VENDOR_DATA attribute.

Most of the earlier instances were addressed by adding NLA_F_NESTED
flag in nla_nest_start(). This commit addresses the remaining
instance in which NL80211_ATTR_VENDOR_DATA is populated using data
set by user through the control interface.

Enhance the control interface VENDOR command to indicate whether the
vendor subcommand uses nested attributes within NL80211_ATTR_VENDOR_DATA
attribute or not.

Set NLA_F_NESTED flag for existing QCA vendor commands which use nested
attributes within the NL80211_ATTR_VENDOR_DATA attributes so that the
old frameworks implementations for already existing commands work
without any issues.

ad6e4a5c59 build: Remove hostapd vs. wpa_supplicant build checks
These are no longer needed now. Note that this was never actually

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.

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.
