rsi: Fix NULL pointer dereference in kmalloc

2019-05-31T13:43:23Z

[ Upstream commit d5414c2355b20ea8201156d2e874265f1cb0d775 ] kmalloc can fail in rsi_register_rates_channels but memcpy still attempts to write to channels. The patch replaces these calls with kmemdup and passes the error upstream. Signed-off-by: Aditya Pakki Signed-off-by: Kalle Valo Signed-off-by: Sasha Levin

rsi: fix missing null pointer check from a failed ieee80211_probereq_get call

2019-02-28T08:28:36Z

The call to ieee80211_probereq_get can return NULL if a skb allocation fails, so add a null pointer check and free an earlier skb on the error exit return path. Fixes: 7fdcb8e12660 ("rsi: add support for hardware scan offload") Signed-off-by: Colin Ian King Signed-off-by: Kalle Valo

rsi: fix for wowlan wakeup failure

2019-02-08T15:29:42Z

During wowlan regression tests, sometimes radio is not waking up for wowlan packet in coex mode. This is because of power save is enabled by default in case of coex mode greater than one. Hence, disable power save in coex mode to avoid radio loss. Signed-off-by: Siva Rebbagondla Signed-off-by: Kalle Valo

rsi: resolve power save issue after S4 resume

2019-02-08T15:29:40Z

We are redownloading the firmware after S4 restore and observed in stress test that mac80211 sometimes gives power save request after resume which causes the firmware in bad state. mac_ops_resumed flag is added to skip that request until initialisation is done and Keeping power save state is NONE.

rsi: fix wowlan wakeup issue for hibernate(S4)

2019-02-08T15:29:39Z

At SDIO restore ieee80211_restart_hw() is getting called to restart all MAC operations. This step is not required. Returning 1 from mac80211_resume() will serve this purpose. Signed-off-by: Siva Rebbagondla Signed-off-by: Kalle Valo

rsi: add hci detach for hibernation and poweroff

2019-02-08T15:29:35Z

As we missed to detach HCI, while entering power off or hibernation, an extra hci interface gets created whenever system is woken up, to avoid this we added hci_detach() in rsi_disconnect(), rsi_freeze(), and rsi_shutdown() functions which are invoked for these tests.
