From: Marcus Glocker Subject: qwz: enable WPA2 association on WCN7850 To: tech@openbsd.org Cc: Mark Kettenis , "Kirill A. Korinsky" , Stefan Sperling , Patrick Wildt Date: Sat, 25 Apr 2026 23:56:07 +0200 Bring the qwz driver up to a working WPA2 client connection on the Qualcomm WCN7850 chip. Tested on the Samsung Galaxy Book4 Edge. Major changes: 1. Fix the RX path. Wire up the WCN7850 descriptor accesses that were unset; override the descriptor size to match what the FW actually writes (512 bytes instead of struct sizeof 472); add the first-line filters that drop FW-injected garbage frames before net80211 mistakes them for fake auth/deauth. 2. Fix the TX path. Port Linux's WiFi7 "TX bank" infrastructure: a per-VDEV register that holds encap/encrypt/search settings the descriptor used to carry inline. Rewrite the TX descriptor builder for the WiFi7 wire format. Fix an encrypt_type default that was making the FW try to WEP-encrypt plain-text EAPOL frames. 3. Fix MSI interrupt routing. Correct the DP IRQ group's MSI vector calculation, and free the vector DP group 0 needs (was being held by an unused pktlog interrupt). Without these, RX completions never fired regardless of how correct the rest of the path was. 4. Make the WPA2 4-way handshake complete. Move WMI_PEER_AUTHORIZE to fire after key install, not before; the old order told the FW crypto was up while plain-text EAPOL was still in flight, crashing the FW. Mask the AID to its 14-bit value before handing it to the FW. Add the missing REO queue setup for non-QoS frames, which is where EAPOL lives. 5. Add non-coherent DMA cache sync on RX and TX. Without explicit flushes the CPU and FW see different bytes for the same buffer. This was the root cause of "garbage RX frames": they were always real EAPOL Msg 1 frames torn by stale CPU cache lines. 6. Update register/descriptor defines from ath11k to ath12k WiFi7. The TX descriptor wire format changed completely between generations: bit positions, field set, even the number of 32-bit words. Partial updates wouldn't have worked. 7. Cleanup. Remove some debug printfs and the diagnostic counters added during the bring-up to verify the path was working. Known limitations: - Firmware occasionally crashes after sustained traffic; driver recovers via the existing RDDM path in if_qwz_pci.c without a system reboot. Root-causing this is the next follow-up. - One PN-replay loop in qwz_dp_peer_rx_pn_replay_config doesn't iterate the non-QoS TID slot. Cosmetic for normal use; will land as a separate small commit. Further testing, feedback, OKs, welcome.
