2017-01-21iwlwifi: fix kernel crash when unregistering thermal zoneJens Axboe
A recent firmware change seems to have enabled thermal zones on the iwlwifi driver. Unfortunately, my device fails when registering the thermal zone. This doesn't stop the driver from attempting to unregister the thermal zone at unload time, triggering a NULL pointer deference in strlen() off the thermal_zone_device_unregister() path. Don't unregister if name is NULL, for that case we failed registering. Do the same for the cooling zone. Signed-off-by: Jens Axboe <axboe@fb.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2017-01-20rtlwifi: rtl8192cu: Convert driver to use common macrosLarry Finger
These drivers use a set of complicated macros to extract and insert information for the RX and TX descriptors. Driver rtl8192cu had a different set than was used for the PCI-based drivers. To simplify the code, rtl8192cu is switched to use the common version. In the process, two errors in those common macros were found and fixed. Besides simplifying the code, there is an additional benefit. We have no BE hardware to test the PCI driver, but using the common macros provides an additional test for the validity of many endian-sensitive operations.

2017-01-20rtlwifi: rtl8192cu: Calculate descriptor checksum correctly for BELarry Finger
This driver requires a checksum for the descriptors so that the wifi chip is assured that the USB transmission was correct. These entries are little-endian, but the driver was always using cpu order in the calculation. As a result, the driver failed on BE hardware.

2017-01-20rtlwifi: Download firmware as bytes rather than as dwordsLarry Finger
The firmware is read from disk as a little-endian byte string. The code that loads the firmware into the device transfers it as 4-byte quantities. The routines that write multi-byte quantities on BE hardware assume that the data are in CPU order, and automatically do the conversion to the LE order required by the device. As a result, the firmware is transmitted incorrectly. Rather than do multiple byte swaps on the data, the download routine is revised to transmit bytes rather than dwords. Although the number of I/O operations is increased, the firmware is not often loaded. All drivers have the same bug, and use essentially the same code to download firmware. These routines have been moved into rtlwifi. Some CamelCase variables have been renamed.

2017-01-20rtlwifi: Remove debugging entry in sysfsLarry Finger

2017-01-20rtlwifi: Convert COMP_XX entries into a proper debugging maskLarry Finger
The debugging macros contain a parameter COMP_XX that could be used as a mask; however, the code turns all these various bits on at the same time. This change implements them as a proper mask, and adds module parameters to set the mask at load time. The current name "debug" for the debug level has been changed to "debug_level" to better differentiate it from "debug_mask". The debug routines have also been changed to interrogate the structure that is loaded at entry time. As a result, the structure rtl_debug is no longer needed, and all references to it are deleted.

In mwifiex_delay_for_sleep_cookie(), we're looping and waiting for the PCIe endpoint to write a magic value back to memory, to signal that it has finished going to sleep. We're not letting the compiler know that this might change underneath our feet though. Let's do that, for good hygiene. I'm not aware of this fixing any concrete problems. I also give no guarantee that this loop is actually correct in any other way, but at least this looks like an improvement to me.

2017-01-20mwifiex: pcie: don't loop/retry interrupt status checksBrian Norris
The following sequence occurs when using IEEE power-save on 8997: (a) driver sees SLEEP event (b) driver issues SLEEP CONFIRM (c) driver recevies CMD interrupt; within the interrupt processing loop, we do (d) and (e): (d) wait for FW sleep cookie (and often time out; it takes a while), FW is putting card into low power mode (e) re-check PCIE_HOST_INT_STATUS register; quit loop with 0 value But at (e), no one actually signaled an interrupt (i.e., we didn't check adapter->int_status). And what's more, because the card is going to sleep, this register read appears to take a very long time in some cases -- 3 milliseconds in my case! Now, I propose that (e) is completely unnecessary. If there were any additional interrupts signaled after the start of this loop, then the interrupt handler would have set adapter->int_status to non-zero and queued more work for the main loop -- and we'd catch it on the next iteration of the main loop. So this patch drops all the looping/re-reading of PCIE_HOST_INT_STATUS, which avoids the problematic (and slow) register read in step (e). Incidentally, this is a very similar issue to the one fixed in commit ec815dd2a5f1 ("mwifiex: prevent register accesses after host is sleeping"), except that the register read is just very slow instead of fatal in this case. Tested on 8997 in both MSI and (though not technically supported at the moment) MSI-X mode. Signed-off-by: Brian Norris <briannorris@chromium.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2017-01-20mwifiex: pcie: use posted write to wake up firmwareBrian Norris
Depending on system factors (e.g., the PCIe link PM state), the first read to wake up the Wifi firmware can take a long time. There is no reason to use a (blocking, non-posted) read at this point, so let's just use a write instead. Write vs. read doesn't matter functionality-wise -- it's just a dummy operation. But let's make sure to re-write with the correct "ready" signature, since we check for that in other parts of the driver. This has been shown to decrease the time spent blocking in this function on RK3399. Signed-off-by: Brian Norris <briannorris@chromium.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2017-01-19ath10k: fix per station tx bit rate reportingMohammed Shafi Shajakhan
Not clearing the previous tx bit rate status results in a ambigous tx bit rate reporting to mac80211/cfg80211, for example the previous bit rate status would have been marked as legacy rate , while the current rate would have been an HT/VHT rate with the tx bit rate flags set and this results in exporting tx bitrate as legacy rate but with HT/VHT rate flags set, fix this by clearing the tx bitrate status for each event. This also fixes the below warning when we do: iw dev wlan#N station dump WARNING: net/wireless/util.c:1222 cfg80211 [<c022f104>] (warn_slowpath_null) from [<bf3b9adc>] (cfg80211_calculate_bitrate+0x110/0x1f4 [cfg80211]) [<bf3b9adc>] (cfg80211_calculate_bitrate [cfg80211]) from [<bf3dcd54>] (nl80211_put_sta_rate+0x44/0x1dc [cfg80211]) [<bf3dcd54>] (nl80211_put_sta_rate [cfg80211]) from [<bf3cbc34>] (nl80211_set_interface+0x724/0xd70 [cfg80211]) [<bf3cbc34>] (nl80211_set_interface [cfg80211]) from [<bf3d0a18>] (nl80211_dump_station+0xdc/0x100 [cfg80211]) [<bf3d0a18>] (nl80211_dump_station [cfg80211]) Fixes: cec17c382140 ("ath10k: add per peer htt tx stats support for 10.4") Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2017-01-19ath10k: prevent sta pointer rcu violationMichal Kazior
Station pointers are RCU protected so driver must be extra careful if it tries to store them internally for later use outside of the RCU section it obtained it in. It was possible for station teardown to race with some htt events. The possible outcome could be a use-after-free and a crash. Only peer-flow-control capable firmware was affected (so hardware-wise qca99x0 and qca4019). This could be done in sta_state() itself via explicit synchronize_net() call but there's already a convenient sta_pre_rcu_remove() op that can be hooked up to avoid extra rcu stall. The peer->sta pointer itself can't be set to NULL/ERR_PTR because it is later used in sta_state() for extra sanity checks.
