The publication context is checked for NULL in bt_mesh_model_publish()
however it was dereferenced before that. Move the assignment to
ctx.send_rel to the same place where other ctx members are set.
Split mesh_util.h into mesh_byteorder.h, mesh_compiler.h,
mesh_ffs.h and mesh_util.h based on the classification of
Zephyr, which will make further porting more clear.
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.

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.
1. fix the bug for softAP update second channel wrong
2. change wifi_scan_time_t from union to struct
3. query country code wrong when policy change from manual to auto
4. fix the timeout issue of EAPOL four-way handshake
5. fix the crash issue when fetch peer after delete the cur_peer
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.
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 theis
data after SAE handshake is complete or event fails.
3. Update wifi lib which includes memory leak fix during BIP
encryption/decryption operations.
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.
EAP reauth frames are dropped at various stages due to current
implementation of WPA2 ENT states and EAP SM init/deinit logic.
Route EAPOL frames based on EAP pkt type and maintain EAP SM
to facilitate EAP re-authentication process.
Added WPA3 Testcases support for -
1. Anti-Clogging Token Request support
2. Return correct status from SAE modules for invalid scenarios
3. Add PMK Caching support for WPA3
wifi lib includes fixes for below PMF Certification issues -
1. Check return status of decrypt operation. Fixes 5.3.3.1.
2. Allow PMF negotiation for WPA2-Enterprise. Fixes 5.3.3.2, 5.3.3.4.
3. Add NULL check on key before encrypting PMF, fixes crash.
1. Add changes in 4-way handshake path to allow SAE key mgmt.
2. Support for configuring WAP3 at init time, added Kconfig option.
3. Handle and propagate error conditions properly.
Under WPA3-Personal, SAE authentication is used to derive PMK
which is more secure and immune to offline dictionary attacks.
1. Add modules to generate SAE commit/confirm for the handshake
2. Add modules that build and parse SAE data in Auth frames
3. Add WPA3 association and key mgmt definitions
4. Invert y-bit while solving for ECC co-ordinate -
Once an X co-ordinate is obtained, solving for Y co-ordinate
using an elliptical curve equation results in 2 possible values,
Y and (P - Y), where p is the prime number. The co-ordinates are
used for deriving keys in SAE handshake. As par the 802.11 spec
if LSB of X is same as LSB of Y then Y is chosen, (P - Y) otherwise.
This is not what is implemented, so fix this behavior to obtain the
correct Y co-ordinate.
This change ports SAE(Simultaneous Authentication of Equals)
feature from wpa_supplicant and makes it work with mbedtls
crypto APIs. Currently only group 19 is supported. A sample
SAE handshake is included in the testcase. Other minor
changes for DH groups are also included.
1. Add CCMP, AES crypto modules for unicast protected Mgmt frames
2. Add support for computing SHA256 MIC on Bcast Mgmt frames
3. Add support for storing iGTK during 4-way handshake.
4. Provide APIs to MLME for utilizing the SW crypto modules
1. Add APIs for configuring PMF through set config.
2. Map Supplicant and Wifi Cipher types.
3. Add support for PMF negotiation while generating RSN IE.
1) Added PMK caching module from wpa_supplicant.
2) Modified wpa_sm to
a) Add entry to PMK cache when first time associated to an AP.
b) Maintain entry across the associations.
c) Clear current PMKSA when deauth happens.
d) Search for an entry when re-associating to the same AP and
set it as current PMKSA
e) Wait for msg 1/4 from AP instead of starting EAP authentication.
f) Check PMKID in msg 1 with current PMKSA/cache.
g) Use the cached PMK to complete 4-way handshake.
3) Remove config_bss callback as it was redundant and used to cause
problems for PMK caching flow.
Closes IDF-969
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.
