staging: wfx: fix double free

2020-06-17T14:42:44+00:00

[ Upstream commit 832cc98141b4b93acbb9231ca9e36f7fbe347f47 ] In case of error in wfx_probe(), wdev->hw is freed. Since an error occurred, wfx_free_common() is called, then wdev->hw is freed again.

staging: wfx: fix RCU usage between hif_join() and ieee80211_bss_get_ie()

2020-03-11T07:14:16+00:00

Access to result of ieee80211_bss_get_ie() is protected by RCU. In other hand, function hif_join() can sleep and cannot be called with RCU locked. Provide a copy of "ssidie" to hif_join() to solve this behavior.

staging: wfx: fix RCU usage in wfx_join_finalize()

2020-03-11T07:14:16+00:00

Access to sta->ht_cap is protected by RCU. However, hif_set_association_mode() may sleep, so it can't be called in RCU. This patch fix this behavior by handling sta and its RCU directly from function hif_set_association_mode().

staging: wfx: fix warning about freeing in-use mutex during device unregister

2020-03-11T07:14:16+00:00

After hif_shutdown(), communication with the chip is no more possible. It the only request that never reply. Therefore, hif_cmd.lock is never unlocked. hif_shutdown() unlock itself hif_cmd.lock to avoid a potential warning during disposal of device. hif_cmd.key_renew_lock should also been unlocked for the same reason.
