Johannes Berg d8dec42b5c mac80211: keep BHs disabled while calling drv_tx_wake_queue() ... Drivers typically expect this, as it's the case for almost all cases where this is called (i.e. from the TX path). Also, the code in mac80211 itself (if the driver calls ieee80211_tx_dequeue()) expects this as it uses this_cpu_ptr() without additional protection. This should fix various reports of the problem: https://bugzilla.kernel.org/show_bug.cgi?id=204127 https://lore.kernel.org/linux-wireless/CAN5HydrWb3o_FE6A1XDnP1E+xS66d5kiEuhHfiGKkLNQokx13Q@mail.gmail.com/ https://lore.kernel.org/lkml/nycvar.YFH.7.76.1909111238470.473@cbobk.fhfr.pm/ Cc: stable@vger.kernel.org Reported-and-tested-by: Jiri Kosina <jkosina@suse.cz> Reported-by: Aaron Hill <aa1ronham@gmail.com> Reported-by: Lukas Redlinger <rel+kernel@agilox.net> Reported-by: Oleksii Shevchuk <alxchk@gmail.com> Fixes: 21a5d4c3a4 ("mac80211: add stop/start logic for software TXQs") Link: https://lore.kernel.org/r/1569928763-I3e8838c5ecad878e59d4a94eb069a90f6641461a@changeid Reviewed-by: Toke Høiland-Jørgensen <toke@redhat.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>		2019-10-01 17:56:19 +02:00
