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.
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.
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.
This is a regression from earlier commit related to TLSV12 which used
sha functions that are currently declared static.
Solution: Follow upstream code structure and resolve the errors.
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
1. Fix WiFi log print level
2. Optimize WiFi/BT coexist sleep
- If any data tx/rx in WiFi slice, fore wakeup next TBTT
- Increase active timeout time to coex TBTT interval to avoid sleep in WiFi slice
3. Fix esp_wifi_stop() crash
esp_wifi_stop() crashes if it's called when WiFi is not initialized.
4. Fix esp_wifi_stop() leads to memory leak
5. esp_wifi_sta_get_ap_info() returns actual values of group ciphers
It is not possible to write to Flash when the stack is located in
PSRAM, and it is not possible to write PSRAM buffers into Flash when
malloc can not be used.
and all ECDSA to be disabled if secure boot is not enabled
Previously if ECDSA disabled in config then secure_boot_signatures.c would
fail to build (whether or not secure boot was enabled).
To avoid breaking apps that might be using the signature scheme with custom OTA
without enabling secure boot signatures in config, this change just disables
this functionality if unavailable in mbedTLS config.
