db5e53cb06 mesh: Fix struct hostapd_data initialization
The local custom version of allocating and initializing struct
hostapd_data within wpa_supplicant_mesh_init() is problematic. This has
already missed couple of initialization steps that are required. Instead
of trying to remember to keep this up to date, use
hostapd_alloc_bss_data() so that there is only one place for this
initialization.

This is fixing a recent issue where FILS HLP started using
hapd->dhcp_server and expected that to be initialized to -1. For the
mesh case, that did not happen and when removing the interface, the FILS
HLP implementation ended up unregistering eloop socket for
hapd->dhcp_server (= 0). This could result in missing socket callbacks
for an arbitrary socket.

274e76f22f mesh: Fix channel configuration in pri/sec switch case
If 20/40 MHz co-ex scan resulted in switching primary and secondary
channels, mesh setup failed to update the frequency parameters for
hostapd side configuration and that could result in invalid secondary
channel configuration preventing creating of the mesh network. This
could happen, e.g., when trying to set up mesh on 5 GHz channel 36 and
co-ex scan finding a BSS on channel 40. Switching the pri/sec channels
resulted in hostapd code trying to check whether channel 32 is
available. Fix this by swapping the channels for hostapd configuration
when needed.

f2f8616e80 Initialize hapd->nr_db in hostapd_alloc_bss_data()
Previously, this was initialized in hostapd_setup_bss() which made it
possible for a REMOVE_NEIGHBOR control interface command to be issued
prior to the list head pointers having been set. That resulted in a NULL
pointer dereference. Fix this by initializing the list head at the time
the data structure gets allocated.

4976618c76 mesh: Mark wpa_state COMPLETED when mesh join has been performed
In mesh interface, the wpa_supplicant state was either
DISCONNECT/SCANNING in non-secured connection or AUTHENTICATING in
secured connection. The latter prevented the scan. Update the
wpa_supplicant state in mesh to be COMPLETED upon initialization. This
is similar to the P2P GO case.

9f2cf23e2e mesh: Add support for PMKSA caching
This patch add functionality of mesh SAE PMKSA caching. If the local STA
already has peer's PMKSA entry in the cache, skip SAE authentication and
start AMPE with the cached value.

If the peer does not support PMKSA caching or does not have the local
STA's PMKSA entry in the cache, AMPE will fail and the PMKSA cache entry
of the peer will be removed. Then STA retries with ordinary SAE
authentication.

If the peer does not support PMKSA caching and the local STA uses
no_auto_peer=1, the local STA can not retry SAE authentication because
NEW_PEER_CANDIDATE event cannot start SAE authentication when
no_auto_peer=1. So this patch extends MESH_PEER_ADD command to use
duration(sec). Throughout the duration, the local STA can start SAE
authentication triggered by NEW_PEER_CANDIDATE even though
no_auto_peer=1.

This commit requires commit 70c93963ed
('SAE: Fix PMKID calculation for PMKSA cache'). Without that commit,
chosen PMK comparison will fail.

d06a35052f mesh: Fix VHT Operation information in peering messages
The full VHT channel information was not set in the hostapd data
structures which resulted in incorrect information (all zeros) being
used when building the VHT Operation element for peering messages while
the actual driver mode was set with the full details. We did not seem to
use the VHT information from peering messages, so this does not change
behavior with another wpa_supplicant-based mesh implementation. Anyway,
these elements should match the ones used in Beacon frames.

ecd40fef74 mesh: Fix mesh SAE auth on low spec devices
The mesh SAE auth often fails with master branch. By bisect I found
commit eb5fee0bf5 ('SAE: Add side-channel
protection to PWE derivation with ECC') causes this issue. This does not
mean the commit has a bug. This is just a CPU resource issue.

After the commit, sae_derive_pwe_ecc() spends 101(msec) on my PC (Intel
Atom N270 1.6GHz). But dot11RSNASAERetransPeriod is 40(msec). So
auth_sae_retransmit_timer() is always called and it can causes
continuous frame exchanges. Before the commit, it was 23(msec).

On the IEEE 802.11 spec, the default value of dot11RSNASAERetransPeriod
is defined as 40(msec). But it looks short because generally mesh
functionality will be used on low spec devices. Indeed Raspberry Pi B+
(ARM ARM1176JZF-S 700MHz) requires 287(msec) for new
sae_derive_pwe_ecc().

So this patch makes the default to 1000(msec) and makes it configurable.

This issue does not occur on infrastructure SAE because the
dot11RSNASAERetransPeriod is not used on it.

41312fc7ef mesh: Leave mesh in driver setup if initialization fails
It was possible to leave the driver in mesh point state if upper layer
mesh initialization failed in wpa_supplicant_mesh_init(). With nl80211,
this results in the vif being left in mesh point mode instead of
restoring it to station mode. That seems to break normal functionality,
e.g., for Public Action frame TX/RX. Fix this by restoring station mode
on mesh failure path.

This error could be triggered, e.g., with the following hwsim test case
sequence: wpas_mesh_secure_sae_missing_password
nfc_p2p_static_handover_tagdev_go_forced_freq

1772d348ea P2P: Fix interface deinit for failed group interface initialization

hitting this check. Fix this by assigning wpa_s->parent as part of
