Company Focus Areas

Intel

  • Luiz Augusto von Dentz contributed patches for HCI reset functions and LE Set Host Feature V2 command emulation.

Qualcomm

  • Shuai Zhang and Yepuri Siddu worked on hardware support for QCC2072 and SSR delay improvements.

Collabora

  • Frédéric Danis focused on MGMT event validation and collaboration with PipeWire.

  1. Increased focus on security fixes, including heap over-read and use-after-free vulnerabilities.
  2. Hardware support enhancements, particularly for Synaptics BCM4384 and QCC2072.
  3. Refactoring efforts in HCI reset functions and advertising TLV validation.
  4. Collaboration between PipeWire and BlueZ teams for future integration.
  5. Independent contributors actively addressing critical bugs and proposing new features.
