The Friend queue uses the message SeqAuth to determine whether the
message is already in the queue. To facilitate this, the SeqAuth is
passed around as a pointer throughout the transport modules. In the
bt_mesh_ctl_send functions, this parameter is also exposed in the API,
but the internal usage is inconsistent and buggy. Also, no one actually
uses this parameter.
- Removes seq_auth param from bt_mesh_ctl_send, instead passing NULL
directly to the friend module, to enforce its addition to the queue.
- Makes the seq_auth pointer const throughout the friend module.
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.
Implements several changes to the transport layer segmented tx to
improve group message performance:
- Moves retransmit counter to tx context instead of per packet. As every
unacked packet is sent every retransmit, the retransmit counters would
be the same in each segment. This makes it easier to control progress.
- Delays the scheduling of the retransmit until the completion of the
last segment by adding a seg_pending counter. This is essentially the
same as the old behavior, except that the old behavior might retrigger
the sending before all segments are finished if the advertising is
slow.
- Allows the group transmits to stop as soon as all retransmits have
been exhausted, instead of timing out waiting for acks that won't
come. This allows group tx to finish without error.
- Fixes a bug where a failed TX would block IV update.
- Cancels any pending transmissions of acked segments.
- Reduces log level for several common group tx scenarios that aren't
erronous.
Backport of https://github.com/apache/mynewt-nimble/pull/724
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."
Until now the choice of reliable sending (segmented messages with
acks) was implicitly dependent on the size of the payload. Add a new
member to the bt_mesh_model_pub to force using segment acks even when
the payload would fit a single unsegmented message.
When PB-GATT support has been enabled the provisioning code "borrows"
the buffer from the proxy code. However, the way that initialization
was happening the proxy buffers were initialized only after
provisioning initialization, resulting in a corrupted buffer with
buf->data pointing to NULL. Reorder the initialization calls so that
proxy is done first and provisioning only after it.
Allow models to skip a periodic publish interval by returning an error
from the publish update callback.
Previously, an error return from publish update would cancel periodic
publishing. This can't be recovered from, and as such, no valid model
implementation could return an error from this callback, and there was
no way to skip a periodic publish.
The function bt_mesh_ctl_send() used to support maximum length of
11 bytes. The segmentation complies with the BLE Mesh Standard.
The ack is disabled in case of non unicast address.
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 only mesh node info is supported to be stored
in flash. So when trying to reset the node, we only need
to judge if the BLE_MESH_VALID flag is set.
Currently we support storing both node & Provisioner info
in flash, when trying to erase the node info from flash,
the BLE_MESH_NODE flag will be checked. So we need to set
bt_mesh.flags to 0 when all the erase operations are done.
It was observed that after sending credentials, if the first
Wi-Fi conection attempt fails, the Wi-Fi provisioning managager
ignores subsequent Wi-Fi events. So, even if the device eventually
connects to the AP, the provisioning stays on indefinitely.
Changing a check so that subsequent events are also captured and
provisioning finishes successfully.

During BLE Mesh Provisioner initialization, the stack will restore
the nodes information if settings storage is enabled.
Previously when a failure happens (e.g. found the same uuid) during
the restore procedure, the information of the following nodes will
not be restored and error will be directly returned.
But this will introduce some problem with user experience, because
some newly provisioned nodes information will not be restored and
Provisioner will not be able to control those nodes.
So we change the operation here, when a failure happens during the
restore procedure, Provisioner will only ignore the information of
the current node and continue restoring other nodes information.
With this change, if a Provisioner has provisioned the maximum
number of nodes, it can still report the unprovisioned device
beacon from other nodes to the application layer. And this will
be more reasonable compared with the previous implementation.
Previously when the node array of Provisioner is full, no beacon
from unprovisioned devices will be reported, only some warning
logs will be given.
Previously only check the node address when it is assigned by the
application layer. Here we also check the address when the address
is allocated internally. And this will be useful when some mesh
internal tests are performed.
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.
The replay protection list of Provisioner should be at least equal
to the number of nodes with the precondition that each node contains
only one element.
The help information of replay protection list is updated, and the
maximum number of nodes for Provisioner is adjusted based on the
replay protection list size.
Using the ble mesh white list test functions, a node can choose to
only receive mesh messages from a specific node and relay the
messages for it. Messages from other nodes will be ignored.
Commit fc03161f updated esp_ota_get_app_elf_sha256 to store and return
X number of bytes of the hash, but the test case still expected 64 bytes.
Updated test case to use CONFIG value for expected length.
1. add enable PSRAM 2T mode function
2. abort when himem and 2T mode are enabled meanwhile
3. set SPIRAM_2T_MODE as "n" by default, enable it when needed
transport_ws can now be read multiple times in a row to read frames larger than the buffer.
Added reporting of total payload length and offset to the user in websocket_client.
Added local example test for long messages.

5. esp_wifi_sta_get_ap_info() returns actual values of group ciphers
Problem:
mbedtls_ctr_drbg_context was initialized in crypto_ec_point_mul. This
was okay in releases before 2.16.4 as entropy_len used to get set to
MBEDTLS_CTR_DRBG_ENTROPY_LEN in function mbedtls_ctr_drbg_seed. The
function is now changed to set the length to
MBEDTLS_CTR_DRBG_ENTROPY_LEN if previous length is 0 and hence the bug.
Solution:
Initialize mbedtls_ctr_drbg_context in crypto_ec_point_mul.
When a handler instance is the last one in the list und unregisters
itself, the handler iterator will be invalidated by entering free'd
memory. Same applies for event base and id, if they become empty.

getc, getchar, putc, putchar were defined both as functions and as
macros. The macro versions are not thread safe, and should not be used
in multithreaded applications.
Upstream fix: b0f271d1db
The NimBLE host buffers that consume a significant amount of memory are
now allocated dynamically.
The advantage is that, the memory can be reclaimed in cases where BLE
is turned off and not required for the current boot cycle
- Add menuconfig option for NimBLE host flow control
- Include changes in `blecent` example from upstream PR!702
- add ble_hs_lock in ble_gap_unpair Upstream PR!584
- ble_hs_hci_rx_evt, upstream PR!738
1. Add wifi stop check at wifi deinit entry.
2. Add TX packets size check.
3. Reduce wifi bin size.
4. Fix the bug for setting channel when wifi in NULL mode.
5. Place the Vendor Specific element at the end according to the protocol.
6. Coex adjust scheme when bt is in connnected status.
The global interrupts will be disabled before taking current
time for scheduling further bluetooth events. Earlier disabling
interrupts was taking some time because of which WiFi events were
interrupting in current bluetooth scheduling.
Also fixes ble crash issue triggered by ble event irq miss (0x20000).
