Changes the behavior of the message cache to optimize for cache
capacity. Previously, the message cache's primary function was to avoid
decrypting messages multiple times, although the cache's main function
in the spec is to avoid message rebroadcasting. Optimizing for minimal
decryption causes us to fill the network cache faster, which in turn
causes more cache misses, potentially outweighing the advantage.
Now stores src + seq in message cache instead of field hash value. This
cuts cache size in two, while including more of the sequence number than
before.
Adds messages to the cache only after the packet is successfully
decrypted. This reduces noise in the cache, and ensures that no
invalid deobfuscations are added.
Additionally, this fixes a bug where multiple calls to net_decrypt with
the same packet failed, as the message cache found its own entry from
the previous call.

Mesh spec 1.0.1 changes proxy disabling behavior to only affect the
relaying from proxy nodes. Previously, disabling proxy would shut down
all proxy and node activity.
Tweaks from the original commit:
- Removed redundant call to bt_mesh_adv_update() in gatt_proxy_set()
- Removed invalid ref to 4.2.11.1 in node_identity_set()
---
According to Mesh Profile Spec 1.0.1, Section 4.2.11:
"If the Proxy feature is disabled, a GATT client device can connect
over GATT to that node for configuration and control. Messages from
the GATT bearer are not relayed to the advertising bearer."
Moreover some notes have been removed from the spec compared to
version 1.0:
Mesh Profile Spec 1.0, Section 4.2.11:
"Upon transition from GATT Proxy state 0x01 to GATT Proxy state 0x00
the GATT Bearer Server shall disconnect all GATT Bearer Clients."
"The Configuration Client should turn off the Proxy state as the last
step in the configuration process."
Mesh Profile Spec 1.0, Section 4.2.11.1:
"When the GATT Proxy state is set to 0x00, the Node Identity state
for all subnets shall be set to 0x00 and shall not be changed."
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.
Previously the BLE_MESH_MAX_STORED_NODES option is added for
internal mesh test, which will be a little confusing for the
users to understand.
Here we remove this option, instead the BLE_MESH_MAX_PROV_NODES
will be used for all the cases. For mesh internal test, when
the test function is called to add some nodes info, the info
will be stored in the array of provisioned nodes directly.
1. Add an API to set Provisioner static oob value
2. Add an API to deinit BLE Mesh stack
3. Add an API to set Provisioner unicast address
4. Add an API to provision devices with fixed address
5. Add an API to store node composition data
6. Add an API to get node with device uuid
7. Add an API to get node with unicast address
8. Add an API to delete node with device uuid
9. Add an API to delete node with unicast address
10. Add an API for Provisioner to update local AppKey
11. Add an API for Provisioner to update local NetKey
12. Support Provisioner persistent functionality
13. Fix Provisioner entering IV Update procedure
14. Fix an issue which may cause client failing to send msg
15. Use bt_mesh.flags to indicate device role
16. Remove several useless macros
17. Callback RSSI of received mesh provisioning packets
18. Modify the Provisioner disable function
19. Change some log level from debug to info
20. Add parameters to Provisioner bind AppKey completion event
21. Fix node ignoring relay messages issue
22. Support using a specific partition for BLE Mesh
23. Fix compile warning when proxy related macros are disabled
24. Clean up BLE Mesh stack included header files
25. NULL can be input if client message needs no parameters
26. Fix compile warning when BT log is disabled
27. Initilize BLE Mesh stack local variables
28. Support using PSRAM for BLE Mesh mutex, queue and task
29. Add a menuconfig option to enable using memory from PSRAM
30. Clean up sdkconfig.defaults of BLE Mesh examples
For Low Power node and Proxy Server, the two features
depend on BLE_MESH_NODE in Kconfig.in, here in the
stack there is no need to judge if CONFIG_BLE_MESH_NODE
is enabled.
According to Mesh Spec 3.4.5.3, a node shall implement a local
network interface. And here we limit the situation just based
on the spec, and Provisioner directly sending the msg without
passing through the local network interface.
