• CM: 

  • Fix handling of file descriptor in case of /dev/urandom issues

  • Reschedule stability timer only when extender mode

  • Changed order of GRE handling in the bridge when the uplink is lost. First, GRE is removed from bridge. Then, the GRE interface is removed

• PM: Fix bridged VLAN services in offline mode

• WANO: 

  • QoS settings are preserved between WAN restarts

  • Enabled NAT on PPPoE and VLAN interfaces during provisioning

• LTEM:

  • Correct LTE status is displayed in OVSDB (enabled or disabled with layer 2 or 3 support)

  • Prevented deadlock situation when the LTE interface cannot connect to a cellular network

Notable Enhancements

• 6Ghz steering using operating class

• Extended WAN type with dhcp to improve visibility and handling (empty option had same operation)

• Logpull includes WAN configuration from persistent storage

• Added default PPPoe options configuration file

• FSM: 

  • Refactored source code to exclusively use the DPI client plugin framework (SNI, DNS and ADT plugins)

  • Added enhancement to the packet inspection engine to stop inspecting packets more efficiently for multicast flows.

• LTEM: MQTT message publishing when the LTE failover is completed

• Extended XM to support DHCP reservation and port forwarding

• kconfig: By default enabled HOSTAP_PSK_FILE_WPS

• Supporting newer OVS versions in LAN stats

Platform Support

• Various QSDK 11.x fixes:

  • Disable HT coexisting on 2.4Ghz STA

  • BSS healthcheck

  • Client statistics

  • CSA offset calculator

  • Unbounded memory write

• Updated QCA and BCM base kconfig multicast default settings

• Forward action frames to user space (platform/qca)

• Fixes for Qualcomm 11ax platforms (QSDK 11.x or newer):

  • Applied a missing fix from 11ac code for ht_mode reporting during onboarding, if only STA is present, without an AP (platform/qca)

  • Fixed an issue in the code for obtaining the client list (platform/qca)

In Development *

• PWM (or Public Wi-Fi Manager) - a manager for management of Public AP’s (beta)

• osp_l2uf API for L2UF operations, with libpcap implementation (beta)

• osp_sec API for simple encrypt/decrypt operations, with an openssl implementation (beta)
