Hi, v9: - switched the patch order, now RCU fixes are done before the scheduled scan tweaks - fix the RCU code according to comments from v8 v8: - reworked the RCU code and placed it in patch 2 v7: - convert the cfg80211_sched_scan_request to __rcu pointer in order to avoid races when accessing it - reverting the patch v6, the port id is back in request struct v6: - moved owner netlink port id from cfg80211_sched_scan_request to rdev in order to avoid possible races v5: - discarded the locking changes in v4 - instead of trying to schedule sched_scan_stop worker from struct cfg80211_sched_scan_request, move the worker to wiphy as that makes it easier to manage the sched_scan_stop worker. There are also one scheduled scan / wiphy so it is also logical to do it like this. v4: - rtnl locking issues fixed in patch 2 v3: - backward compatibility define tweaked in patch 1 - added missing signed-off-by: v2: - split the patch - In patch 1, use a generic NL80211_ATTR_SOCKET_OWNER attribute and convert the old code that uses NL80211_ATTR_IFACE_SOCKET_OWNER to use the new value. A define is provided for backward compatibility. - Any pending schedule scan stop worker is cancelled when interface is taken down in patch 2 Jukka Rissanen (2): nl80211: Convert sched_scan_req pointer to RCU pointer nl80211: Stop scheduled scan if netlink client disappears include/net/cfg80211.h | 2 ++ include/uapi/linux/nl80211.h | 3 +++ net/wireless/core.c | 26 +++++++++++++++++++++++--- net/wireless/core.h | 4 +++- net/wireless/nl80211.c | 35 +++++++++++++++++++++++++++-------- net/wireless/scan.c | 13 ++++++++----- 6 files changed, 66 insertions(+), 17 deletions(-) -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
