As part of hw reconfig, only stations linked to AP interfaces are added back to the driver ignoring those which are tied to AP_VLAN interfaces. It is true that there could be stations tied to the AP_VLAN interface while serving 4addr clients or when using AP_VLAN for VLAN operations; we should be adding these stations back to the driver as part of hw reconfig, failing to do so can cause functional issues. In the case of ath10k driver, the following errors were observed. ath10k_pci : failed to install key for non-existent peer XX:XX:XX:XX:XX:XX Workqueue: events_freezable ieee80211_restart_work [mac80211] (unwind_backtrace) from (show_stack+0x10/0x14) (show_stack) (dump_stack+0x80/0xa0) (dump_stack) (warn_slowpath_common+0x68/0x8c) (warn_slowpath_common) (warn_slowpath_null+0x18/0x20) (warn_slowpath_null) (ieee80211_enable_keys+0x88/0x154 [mac80211]) (ieee80211_enable_keys) (ieee80211_reconfig+0xc90/0x19c8 [mac80211]) (ieee80211_reconfig]) (ieee80211_restart_work+0x8c/0xa0 [mac80211]) (ieee80211_restart_work) (process_one_work+0x284/0x488) (process_one_work) (worker_thread+0x228/0x360) (worker_thread) (kthread+0xd8/0xec) (kthread) (ret_from_fork+0x14/0x24) Also while bringing down the AP VAP, WARN_ONs and errors related to peer removal were observed. ath10k_pci : failed to clear all peer wep keys for vdev 0: -2 ath10k_pci : failed to disassociate station: 8c:fd:f0:0a:8c:f5 vdev 0: -2 (unwind_backtrace) (show_stack+0x10/0x14) (show_stack) (dump_stack+0x80/0xa0) (dump_stack) (warn_slowpath_common+0x68/0x8c) (warn_slowpath_common) (warn_slowpath_null+0x18/0x20) (warn_slowpath_null) (sta_set_sinfo+0xb98/0xc9c [mac80211]) (sta_set_sinfo [mac80211]) (__sta_info_flush+0xf0/0x134 [mac80211]) (__sta_info_flush [mac80211]) (ieee80211_stop_ap+0xe8/0x390 [mac80211]) (ieee80211_stop_ap [mac80211]) (__cfg80211_stop_ap+0xe0/0x3dc [cfg80211]) (__cfg80211_stop_ap [cfg80211]) (cfg80211_stop_ap+0x30/0x44 [cfg80211]) (cfg80211_stop_ap [cfg80211]) (genl_rcv_msg+0x274/0x30c) (genl_rcv_msg) (netlink_rcv_skb+0x58/0xac) (netlink_rcv_skb) (genl_rcv+0x20/0x34) (genl_rcv) (netlink_unicast+0x11c/0x204) (netlink_unicast) (netlink_sendmsg+0x30c/0x370) (netlink_sendmsg) (sock_sendmsg+0x70/0x84) (sock_sendmsg) (___sys_sendmsg.part.3+0x188/0x228) (___sys_sendmsg.part.3) (__sys_sendmsg+0x4c/0x70) (__sys_sendmsg) (ret_fast_syscall+0x0/0x44) These issues got fixed by adding the stations which are tied to AP_VLANs back to the driver.
