  "title": "wifi: ath11k: reset ar-\u003Enum_stations on hardware start",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  wifi: ath11k: reset ar-\u003Enum_stations on hardware start  When (multiple) hw restart occurs, we end up in a situation where we cannot accept new stations / mesh peers. This seems to be the \u0027num_stations\u0027 in \u0027struct ath11k\u0027 that did not get reset properly in this case. In ath11k_mac_op_start(), it was indeed the only accounting var that did not get reset so let\u0027s clear it too.  This avoids problems like those:  \t[1248828.088023] WARNING: CPU: 0 PID: 12281 at net/mac80211/util.c:1682 ieee80211_reconfig_stations\u002B0x98/0xc0 \t[1248828.088115] Call trace: \t[1248828.088116]  ieee80211_reconfig_stations\u002B0x98/0xc0 (P) \t[1248828.088119]  ieee80211_reconfig\u002B0x774/0x1438 \t[1248828.088123]  ieee80211_restart_work\u002B0x10c/0x178 \t[1248828.088127]  process_one_work\u002B0x178/0x3c0 \t[1248828.088130]  worker_thread\u002B0x280/0x440 \t[1248828.088133]  kthread\u002B0xe0/0xf8 \t[1248828.088137]  ret_from_fork\u002B0x10/0x20 \t[1248828.088141] ---[ end trace 0000000000000000 ]--- \t[1248836.686604] ath11k_pci 0000:04:00.0: refusing to associate station: too many connected already (128) \t[1248836.686609] ath11k_pci 0000:04:00.0: Failed to add station: xx:xx:xx:xx:xx:xx for VDEV: 1  Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.9.0.1-01977-QCAHKSWPL_SILICONZ-1",
