a6b1215769 GAS: Do not reply to P2P SD query from generic GAS/ANQP server
This avoids an issue where a wpa_supplicant build with CONFIG_P2P=y and
CONFIG_HS20=y ended up processing a P2P SD query twice when operating as
a GO and sending out two replies. Only the P2P SD implementation should
reply to P2P SD query in such a case.

062833c67c GAS server: Fix request frame length validation (CID 68098)
There seemed to be an off-by-one error in the validation of GAS request
frames. If a Public Action frame without the Action code field would
have reached this function, the length could have been passed as
(size_t) -1 which would likely have resulted in a crash due to reading
beyond the buffer. However, it looks like such frame would not be
delivered to hostapd at least with mac80211-based drivers. Anyway, this
function better be more careful with length validation should some other
driver end up reporting invalid Action frames.

In addition, the Action code field is in a fixed location, so the
IEEE80211_HDRLEN can be used here to clean up bounds checking to avoid
false reports from static analyzer.

d0bf06f2d9 GAS server: Remove incomplete remote ANQP processing
Some of the remote ANQP server concepts were introduces into gas_serv.c,
but these were not completed. Remote the unused implementation for now.
It can be added back if support for remote ANQP server is added at some
point.

hostapd can now be configured to provide access for icon files

additional meta data about the icon that is not yet used, but it will be

5ce00d09c0 GAS server: Add support for Protected Dual of Public Action frames
When GAS is used with PMF negotiated, Protected Dual of Public Action
frames are expected to be used instead of Public Action frames, i.e.,
the GAS/ANQP frames are expected to be encrypted. Add support for this
different category of Action frames being used for GAS. The payload
after the Category field is identical, so the only change is in using
the Category field based on what was received in the request frames. For
backwards compatibility, do not enforce protected dual to be used on the
AP side, i.e., follow what the station does.

2d9ffe1e85 P2P: Fix Action frame processing if Interworking is enabled
GAS server used the same public_action_cb mechanism as P2P to process
Action frames. This ended up overriding P2P processing of Action frames
while running an AP/GO interface with a build that enables Interworking
(e.g., for Hotspot 2.0) and a driver that uses hostapd for AP mode
SME/MLME. Fix this by adding a separate callback registration for the
GAS server. This should really be cleaned up by supporting arbitrary
number of callback handlers, but for now, this addresses the regression
with a minimal change.
