Jouni Malinen baae4cb9b4 Simplify HT Capabilities element parsing
Check the element length in the parser and remove the length field from
struct ieee802_11_elems since the element is of fixed length.

Bob Copeland 745d93695b mesh: Create new station entry on popen frames
Currently, there is a race in open mesh networks where mesh STA A
receives a beacon from B and sends a peering open frame to initiate
peering. STA B, having not yet received a beacon from A and thus
created the corresponding station entry, will ignore all such open
frames. If the beacon interval is sufficiently long then peering
will not succeed as a result.

In fact B can simply create the station entry when the popen is
received, as is done in Linux's in-kernel MPM, avoiding the issue.

Bob Copeland 41bff862d9 mesh: Always free the station if peering failed
Previously, we would only free the station entry if a peering close
frame was received (freeing the station entry causes the kernel to
start sending peer candidate events again when suitable beacons are
received, triggering peering or authentication to restart).

The end result is the same in any case regardless of close reason:
if we leave holding state then peering has started again, so go
ahead and remove the station in all cases.

Jouni Malinen 6334330ed6 mesh: Use a separate variable to track whether HT is enabled
A network profile parameter should not be used to check whether the
currently operating mesh has HT enabled.

Jouni Malinen 3a322496f9 mesh: Delay Authentication frame process with no_auto_peer
There is a possible race condition between receiving the
NEW_PEER_CANDIDATE event and the Authentication frame from the peer.
Previously, if the Authentication frame RX event was indicated first,
that frame got dropped silently. Now, this frame is still dropped, but a
copy of it is stored and the frame gets processed on the following
NEW_PEER_CANDIDATE event if that is received for the same peer within
two seconds.

Jouni Malinen 608b0ff52a mesh: Check for initialization failures
It is possible that these location ended up getting called before mesh
startup operations had been completed and that could result in
dereferencing NULL pointers. Address those error cases by verifying that
the needed parameters are available before using them.

Jouni Malinen 763041b2e8 mesh: Avoid a false maybe-uninitialized compiler warning
An earlier check of the action_field value above the switch statement
already took care of all other possible cases, but that was apparently
too difficult for the compiler to notice. Bring back the default case to
avoid incorrect warnings about the event variable being maybe
uninitialized.

Chun-Yeow Yeoh c596f3f083 mesh: Add timer for SAE authentication in RSN mesh
Add timer to do SAE re-authentication with number of tries defined
by MESH_AUTH_RETRY and timeout defined by MESH_AUTH_TIMEOUT.

Ignoring the sending of reply message on "SAE confirm before commit"
to avoid "ping-pong" issues with other mesh nodes. This is obvious when
number of mesh nodes in MBSS reaching 6.
