This is independent functionality from the core IEEE 802.11 management
handling and will increase significantly in size, so it is cleaner to

It was possible to hit this WPA_ASSERT when FST-MANAGER SESSION_REMOVE
command is exececuted when in not-associated state. In
CONFIG_EAPOL_TEST=y builds, this would result in the wpa_supplicant
process being terminated. Convert this WPA_ASSERT to a check that does
not terminate the process, but only rejects the command if wpa_s->bssid
does not match the da argument.

Increase the EAPOL RX frame timeout from 100 to 200 ms. This fixes lack
of optimization (i.e., first EAPOL frame dropped) in occasional roaming
and authentication cases on EAP networks if the kernel events can be
reordered and delayed a bit longer.

Instead of copying the struct wpa_auth_callbacks, just keep a pointer to
it, keep the context pointer separate, and let the user just provide a
static const structure. This reduces the attack surface of heap
overwrites, since the function pointers move elsewhere.

The remote mesh STA which had configuration disable_ht40=1 could have HT
Capabilities element which includes Supported Channel Width Set = 1
(both 20 MHz and 40 MHz operation is supported) even though it had HT
Operation element which includes STA Channel Width = 0 (20 MHz channel
width only). Previously, local peer recognized such a remote peer as 40
MHz band width enabled STA because local peer only checked HT
Capabilities element. This could cause disconnection between
disable_ht40=1 mesh STA and disable_ht40=0 mesh STA. They could
establish a mesh BSS but could not ping with ath9k_htc device. This
commit fixes the issue by refering HT Operation element.

These commnds are mesh version of PMKSA_GET/ADD commands. So the usage
and security risk is similar to them. Refer to
commit 3459381dd2 ('External persistent
storage for PMKSA cache entries') also.
The MESH_PMKSA_GET command requires peer MAC address or "any" as an
argument and outputs appropriate stored PMKSA cache. And the
MESH_PMKSA_ADD command receives an output of MESH_PMKSA_GET and re-store
the PMKSA cache into wpa_supplicant. By using re-stored PMKSA cache,
wpa_supplicant can skip commit message creation which can use
significant CPU resources.
The output of the MESH_PMKSA_GET command uses the following format:
<BSSID> <PMKID> <PMK> <expiration in seconds>
The example of MESH_PMKSA_ADD command is this.
MESH_PMKSA_ADD 02:00:00:00:03:00 231dc1c9fa2eed0354ea49e8ff2cc2dc cb0f6c9cab358a8146488566ca155421ab4f3ea4a6de2120050c149b797018fe 42930

When wpa_supplicant was processing a received Authentication frame (seq
1) from a peer STA for which there was already a TK configured to the
driver, debug log claimed that the PTK gets cleared, but the actual
call to clear the key was actually dropped due to AUTH vs. SUPP set_key
selection. Fix this by explicitly clearing the TK in case it was set
and an Authentication frame (seq 1) is received.
This fixes some cases where EAPOL-Key frames were sent encrypted using
the old key when a peer STA restarted itself and lost the key and had to
re-join the IBSS. Previously, that state required timing out the 4-way
handshake and Deauthentication frame exchange to recover.

wpabuf_resize() can handle the initial allocation of a wpabuf and all
the other callers of wpas_rrm_report_elem() were already using a pointer
to a pointer and a wpabuf_resize() call. Simplify this by resizing the
wpabuf (if needed) within wpas_rrm_report_elem() instead of having to
calculate the needed size in all the callers. Thsi is also fixing one of
the allocation sizes to use the correct size instead of a size of a
struct that has nothing to do with the allocation (but is larger than
the needed five octets, so does not break anything).
