  "message": "wifi: cfg80211: use wiphy work for socket owner autodisconnect\n\nnl80211_netlink_notify() walks the cfg80211 wireless device list when a\nNETLINK_GENERIC socket is released. If the socket owns a connection, the\nnotifier queues the embedded wdev-\u003edisconnect_wk work item.\n\nThat work is a plain work_struct today. NETDEV_GOING_DOWN cancels it, but a\nNETLINK_URELEASE notifier that already observed conn_owner_nlportid can\nqueue it after that cancel returns. _cfg80211_unregister_wdev() then\nremoves the wdev from the list and waits for RCU readers, but\nsynchronize_net() does not drain work queued by such a reader.\n\nMake the autodisconnect work a wiphy_work instead. The callback already\nneeds the wiphy mutex, and wiphy_work runs under that mutex. This lets\nteardown cancel pending autodisconnect work while holding the mutex,\nwithout a cancel_work_sync() vs. worker locking concern.\n\nAlso cancel the wiphy work after list_del_rcu() and synchronize_net(). Any\nNETLINK_URELEASE notifier that had already reached the wdev list has then\neither queued the work and it is removed, or can no longer find the wdev.\n\nFixes: bd2522b16884 (\"cfg80211: NL80211_ATTR_SOCKET_OWNER support for CMD_CONNECT\")\nSuggested-by: Johannes Berg \u003cjohannes@sipsolutions.net\u003e\nAssisted-by: Codex:gpt-5.5\nSigned-off-by: Cen Zhang \u003czzzccc427@gmail.com\u003e\nLink: https://patch.msgid.link/20260706152418.779226-1-zzzccc427@gmail.com\nSigned-off-by: Johannes Berg \u003cjohannes.berg@intel.com\u003e\n",
