From e1696c8bd0056bc1a5f7766f58ac333adc203e8a Mon Sep 17 00:00:00 2001 From: Miri Korenblit Date: Wed, 7 Jan 2026 14:04:51 +0200 Subject: [PATCH] wifi: cfg80211: stop NAN and P2P in cfg80211_leave Seems that there is an assumption that this function should be called only for netdev interfaces, but it can also be called in suspend, or from nl80211_netlink_notify (indirectly). Note that the documentation of NL80211_ATTR_SOCKET_OWNER explicitly says that NAN interfaces would be destroyed as well in the nl80211_netlink_notify case. Fix this by also stopping P2P and NAN.
