Changes in v2.0.1:

🛠️ Multi-Kernel Stability & UsrMerge Compliance Release

This maintenance and stability release ports critical data-plane and multi-kernel fixes from the upstream MT7663 ecosystem, resolving kernel oops on station association across LTS kernels and enforcing modern UsrMerge filesystem compliance.

Added

• Full Co-existence & Driver Isolation with MT7663:
  • Renamed SDIO driver instance in os/linux/hif/sdio/sdio.c from generic "wlan" to "wlan_mt7668" to prevent kernel driver_register -EBUSY collision when both MT7663 and MT7668 modules are loaded.
  • Isolated kernel /proc/net/ debug and MET trace directories to wlan_mt7668 (os/linux/gl_proc.c) and wlan_mt7668_met (os/linux/gl_kal.c), eliminating kernel proc_register "already registered" warnings and call traces during multi-driver boot.
  • Blacklisted obsolete distro-provided MT7668 driver (wlan_mt76x8_sdio) in blacklist-mt7668-bluetooth.conf and debian/postinst to prevent udev-worker from binding competing legacy drivers on Ophub Armbian kernels.
  • Namespaced system integration files to 99-mt7668-throughput.conf, 99-mt7668-performance.rules, and mt7668-irq-tune.sh to allow seamless parallel installation with mt7663-dkms on universal OS images.
  • Added module active guard (if lsmod | grep -q "^wlan_mt7668"; then ... fi) to mt7668-shutdown.service so unbind operations only execute when MT7668 hardware is active.
• Global Station Record Lookup Fallback (cnmGetAnyStaRecByAddress):
  • Implemented cnmGetAnyStaRecByAddress() in mgmt/cnm_mem.c and declared in include/mgmt/cnm_mem.h to look up active station records across all BSS indices.
  • Added fallback in nicEventAddPkeyDone (nic/nic_cmd_event.c and nic/nic_rx.c) preventing BSS index mismatches on virtual interface ap0 from dropping pairwise key completion notifications.
• WPA2/WPA3 Data-Plane Queue Unlocking (fgIsTxKeyReady):
  • Explicitly unlocked the transmission queue (fgIsTxKeyReady = TRUE) and updated station queues (qmUpdateStaRec) immediately upon pairwise key installation in os/linux/gl_p2p_cfg80211.c (mtk_p2p_cfg80211_add_key).
  • Resolves connection loops where client stations authenticate successfully but experience zero data throughput ("connected without internet").
• Universal SDIO Controller Device Matching (ffe03000*):
  • Updated mt7668-shutdown.service to discover and unbind /sys/bus/platform/drivers/meson-gx-mmc/ffe03000* dynamically using wildcard matching, with TimeoutStartSec=2.
  • Ensures clean SDIO reset and reliable warm reboots on FiberHome HG680-FJ regardless of whether the device label is .sd or .mmc.

Fixed

• Multi-Kernel Station Update Compatibility (kalP2PGOStationUpdate):
  • Added preprocessor guard #if (CFG80211_VERSION_CODE >= KERNEL_VERSION(6, 14, 0)) in os/linux/gl_p2p_kal.c.
  • Passes struct net_device * (aprRoleHandler) on Linux kernels < 6.14 (including Linux 5.10 LTS and 6.12 LTS Ophub), and struct wireless_dev * (ieee80211_ptr) on Linux 6.14+.
  • Fixes fatal kernel oops and main_thread crash when stations associate or disconnect.
• Accurate Linux Mainline 6.12+ cfg80211_cac_event Boundary:
  • Corrected macro guard in os/linux/gl_p2p_kal.c to #if KERNEL_VERSION(6, 12, 0) <= CFG80211_VERSION_CODE.
  • Resolves compilation error (too many arguments to function ‘cfg80211_cac_event’) on intermediate Linux kernels (such as Ubuntu 6.8 LTS).
• Key Index Bitmask Authenticator Check (wlanoidSetAddKey):
  • Explicitly permitted IS_AUTHENTICATOR (BIT(28)) in common/wlan_oid.c key index exception validation.
• UsrMerge Packaging Compliance (build-deb.sh):
  • Relocated firmware installation destination from ./lib/firmware/ to ./usr/lib/firmware/ in Debian package build process.
  • Prevents dpkg -x manual extractions from breaking the modern Debian/Armbian /lib -> usr/lib symlink and causing boot panics.
