mac80211: document sleep requirements for channel context ops

2015-11-03T10:15:48+00:00

Channel context driver operations can sleep, so add might_sleep() and document this. Signed-off-by: Chaitanya T K Signed-off-by: Johannes Berg

mac80211: call drv_stop only if driver is started

2015-11-03T09:41:12+00:00

If drv_start() fails during hw_restart, all the running interfaces are being closed/stopped, which results in drv_stop() being called, although the driver was never started successfully. This might cause drivers to perform operations on uninitialized memory (as they assume it was initialized on drv_start) Consider the local->started flag, and call the driver's stop() op only if drv_start() succeeded before. Move drv_start() and drv_stop() to driver-ops.c, as they are no longer simple wrappers. Signed-off-by: Eliad Peller Signed-off-by: Emmanuel Grumbach Signed-off-by: Johannes Berg

mac80211: introduce per vif frame registration API

2015-09-22T13:21:22+00:00

Currently the cfg80211's frame registration api receives wdev, however mac80211 assumes per device filter configuration and ignores wdev. Per device filtering is too wasteful, especially for multi-channel devices. Introduce new per vif frame registration API and use it for probe request registrations in ieee80211_mgmt_frame_register() Also call directly to ieee80211_configure_filter instead of using a work since it is now allowed to sleep in ieee80211_mgmt_frame_register.
