1. Buffers for SAE messages are not freed after the handshake.
This causes memory leak, free buffers after SAE handshake.
2. SAE global data is not freed until the next WPA3 connection
takes place, holding up heap space without reason. Free this
data after SAE handshake is complete or event fails.
3. Update wifi lib which includes memory leak fix during BIP
encryption/decryption operations.
Old version of BLE Mesh has no device role storage, because
previously we only support storing mesh node info.
If the binary of the node is upgraded from old version to a
new version (support storing provisioner info), the mesh info
of the node will not be restored because mesh role does not
exist in the flash.
The tests used to measure the throughput by FreeRTOS
`xTaskGetTickCount()`. The rounding error can be quite big, compared to
total measurement time (1350 ms for 4-bit mode).
This commit use `esp_timer_get_time()` instead to measure typical time,
which is in microseconds. Moreover, to get rid of the time error from
cache miss, `ccomp_timer_*` are used to get the cache compensated time
to measure the throughput used for unit test performance assertion.
When fast provisioning is enabled, Provisioner shall not
ignore messages from the nodes whose addresses are not in
the provisioning database. Because other nodes which are
not provisioned by the Primary Provisioner will send node
address messages to the Primary Provisioner.
This commit fixes a bug as well as changes a behaviour.
Bugfix: During softap/httpd based provisioning, if a session was closed
midway and a new one started, it would never proceed if the http server
assigns same socket number to the new session (which happens almost always).
Now, if a session is closed, using the http callbacks, the older session
data is cleared so that a new one can be created.
Behavioural change: If a client (mobile app particularly) does not use
persistent http session i.e. all provisioning communication on the same
socket, the provisioning may fail. Earlier, since the session context was
not getting cleared, even if the client closed a session and continued
on a new one, it would go through if the socket number assigned was same
(which happens almost always).
Ideally, from a security perspective, all communication related
to secure provisioning must happen on the same socket, and so, this
change is required.
When using fast provisioning, the Provisioner functionality
will be enabled. Unicast addresses within the pre-allocated
range will be used for provisioning nodes. And during the
address assignment, the allocated unicast address will be
checked that if it's duplicated with other nodes addresses
and the Provisioner's own addresses.
So before starting using fast provisioning, we need to update
the Provisioner address.
