rtw88: fix RX clock gate setting while fifo dump

2021-11-17T10:03:48Z

[ Upstream commit c5a8e90730a322f236731fc347dd3afa5db5550e ] When fw fifo dumps, RX clock gating should be disabled to avoid something unexpected. However, the register operation ran into a mistake. So, we fix it. Signed-off-by: Zong-Zhe Yang Signed-off-by: Ping-Ke Shih Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20210927111830.5354-1-pkshih@realtek.com Signed-off-by: Sasha Levin

rtl8187: fix control-message timeouts

commit 2e9be536a213e838daed6ba42024dd68954ac061 upstream. USB control-message timeouts are specified in milliseconds and should specifically not vary with CONFIG_HZ.

rtw88: wow: fix size access error of probe request

2021-09-18T11:43:54Z

[ Upstream commit 69c7044526d984df672b8d9b6d6998c34617cde4 ] Current flow will lead to null ptr access because of trying to get the size of freed probe-request packets. We store the information of packet size into rsvd page instead and also fix the size error issue, which will cause unstable behavoir of sending probe request by wow firmware.

rtw88: wow: build wow function only if CONFIG_PM is on

2021-09-18T11:43:54Z

[ Upstream commit 05e45887382c4c0f9522515759b34991aa17e69d ] The kernel test robot reports undefined reference after we report wakeup reason to mac80211. This is because CONFIG_PM is not defined in the testing configuration file. In fact, functions within wow.c are used if CONFIG_PM is defined, so use CONFIG_PM to decide whether we build this file or not.

rtw88: use read_poll_timeout instead of fixed sleep

2021-09-18T11:43:54Z

[ Upstream commit 02a55c0009a55b204e1e5c17295431f0a9e7d3b6 ] In current wow flow, driver calls rtw_wow_fw_start and sleep for 100ms, to wait firmware finish preliminary work and then update the value of WOWLAN_WAKE_REASON register to zero. But later firmware will start wow function with power-saving mode, in which mode the value of WOWLAN_WAKE_REASON register is 0xea. So driver may get 0xea value and return fail. We use read_poll_timeout instead to check the value to avoid this issue.

rtl8xxxu: Fix the handling of TX A-MPDU aggregation

2021-09-18T11:43:54Z

[ Upstream commit 95a581ab3592082c60a08090aabe09ac7d0bd650 ] The TX A-MPDU aggregation is not handled in the driver since the ieee80211_start_tx_ba_session has never been started properly. Start and stop the TX BA session by tracking the TX aggregation status of each TID. Fix the ampdu_action and the tx descriptor accordingly with the given TID.

rtw88: fix c2h memory leak

2021-06-24T16:21:15Z

Fix erroneous code that leads to unreferenced objects. During H2C operations, some functions returned without freeing the memory that only the function have access to. Release these objects when they're no longer needed to avoid potentially memory leaks.

mac80211: notify driver on mgd TX completion

2021-06-23T11:10:46Z

We have mgd_prepare_tx(), but sometimes drivers may want/need to take action when the exchange finishes, whether successfully or not. Add a notification to the driver on completion, i.e. call the new method mgd_complete_tx(). To unify the two scenarios, and to add more information, make both of them take a struct that has the duration (prepare only), subtype (both) and success (complete only).

rtlwifi: rtl8192de: Fully initialize curvecount_val

2021-06-22T15:24:33Z

In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally writing across neighboring array fields. The size argument to memset() is bytes, but the array element size of curvecount_val is u32, so "CV_CURVE_CNT * 2" was only 1/4th of the contents of curvecount_val. Adjust memset() to wipe full buffer size. Signed-off-by: Kees Cook Reviewed-by: Larry Finger Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20210617171317.3410722-1-keescook@chromium.org
