Unfortunately my channel switch announcement patches contained locking issues which I didn't notice during my test due to bad configuration. Johannes pointed them out, so here is my attempt to fix them. This series attempts to fix two issues: * There are "suspicious rcu_dereference_protected() usage" problems for ieee80211_assign_beacon and ieee80211_ibss_csa_beacon because the respective locking was missing * There is a circular dependency between the wdev/sdata-lock and the csa_finalize worker lock (see description in patch 3). The fix is not really trivial and I'm not an expert on the cfg80211/mac80211 locking, so I'd like to request your critical review. Patches are based on mac80211-next. Thanks, Simon Simon Wunderlich (3): mac80211: modify beacon using sdata/wdev-lock, not rtnl lock cfg80211/mac80211/ath6kl: acquire wdev lock outside ch_switch_notify mac80211: don't cancel csa finalize work within stop_ap drivers/net/wireless/ath/ath6kl/cfg80211.c | 2 + include/net/cfg80211.h | 3 +- net/mac80211/cfg.c | 136 ++++++++++++++++++---------- net/mac80211/ieee80211_i.h | 3 + net/wireless/nl80211.c | 9 +- 5 files changed, 100 insertions(+), 53 deletions(-) -- 1.7.10.4 -- 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
