2020-08-03mac80211: Do not report beacon loss if beacon filtering enabledLoic Poulain
mac80211.h says: Beacon filter support is advertised with the IEEE80211_VIF_BEACON_FILTER interface capability. The driver needs to enable beacon filter support whenever power save is enabled, that is IEEE80211_CONF_PS is set. When power save is enabled, the stack will not check for beacon loss and the driver needs to notify about loss of beacons with ieee80211_beacon_loss(). Some controllers may want to dynamically enable the beacon filter capabilities on power save entry (CONF_PS) and disable it on exit. This is the case for the wcn36xx driver which only supports beacon filtering in PS mode (no CONNECTION_MONITOR support). When the mac80211 beacon monitor timer expires, the beacon filter flag must be checked again in case it as been changed in between (e.g. vif moved to PS mode).

2020-08-03netfilter: flowtable: Set offload timeout when adding flowRoi Dayan
On heavily loaded systems the GC can take time to go over all existing conns and reset their timeout. At that time other calls like from nf_conntrack_in() can call of nf_ct_is_expired() and see the conn as expired. To fix this when we set the offload bit we should also reset the timeout instead of counting on GC to finish first iteration over all conns before the initial timeout.

2020-08-03mac80211: Handle special status codes in SAE commitJouni Malinen
SAE authentication has been extended with H2E (IEEE 802.11 REVmd) and PK (WFA) options. Those extensions use special status code values in the SAE commit messages (Authentication frame with transaction sequence number 1) to identify which extension is in use. mac80211 was interpreting those new values as the AP denying authentication and that resulted in failure to complete SAE authentication in some cases. Fix this by adding exceptions for the new status code values 126 and 127.

2020-08-02md/raid5: Allow degraded raid6 to do rmwChangSyun Peng
Degraded raid6 always do reconstruct-write now. With raid6 xor supported, we can do rmw in degraded raid6. This patch can reduce many read IOs to improve performance. If the failed disk is P, Q or the disk we want to write to, we may need to do reconstruct-write in max degraded raid6. In this situation we can not read enough data from handle_stripe_dirtying() so we have to set force_rcw in handle_stripe_fill() to read all data.

2020-08-02mm: rewrite wait_on_page_bit_common() logicLinus Torvalds
It turns out that wait_on_page_bit_common() had several problems, ranging from just unfair behavioe due to re-queueing at the end of the wait queue when re-trying, and an outright bug that could result in missed wakeups (but probably never happened in practice). This rewrites the whole logic to avoid both issues, by simply moving the logic to check (and possibly take) the bit lock into the wakeup path instead. That makes everything much more straightforward, and means that we never need to re-queue the wait entry: if we get woken up, we'll be notified through WQ_FLAG_WOKEN, and the wait queue entry will have been removed, and everything will have been done for us.

2020-08-02airo: use generic power managementVaibhav Gupta
Drivers using legacy power management .suspen()/.resume() callbacks have to manage PCI states and device's PM states themselves. They also need to take care of standard configuration registers. Switch to generic power management framework using a single "struct dev_pm_ops" variable to take the unnecessary load from the driver. This also avoids the need for the driver to directly call most of the PCI helper functions and device power state control functions, as through the generic framework PCI Core takes care of the necessary operations, and drivers are required to do only device-specific jobs.

2020-08-02ipw2100: Use GFP_KERNEL instead of GFP_ATOMIC in some memory allocationChristophe JAILLET
The call chain is: ipw2100_pci_init_one (the probe function) --> ipw2100_queues_allocate --> ipw2100_tx_allocate No lock is taken in the between. So it is safe to use GFP_KERNEL in 'ipw2100_tx_allocate()'. BTW, 'ipw2100_queues_allocate()' also calls 'ipw2100_msg_allocate()' which already allocates some memory using GFP_KERNEL.

2020-08-02hostap: use generic power managementVaibhav Gupta
Drivers using legacy power management .suspen()/.resume() callbacks have to manage PCI states and device's PM states themselves. They also need to take care of standard configuration registers. Switch to generic power management framework using a single "struct dev_pm_ops" variable to take the unnecessary load from the driver. This also avoids the need for the driver to directly call most of the PCI helper functions and device power state control functions as through the generic framework, PCI Core takes care of the necessary operations, and drivers are required to do only device-specific jobs.

2020-08-02rt2x00: pci: use generic power managementVaibhav Gupta
Drivers using legacy PM have to manage PCI states and device's PM states themselves. They also need to take care of configuration registers. With improved and powerful support of generic PM, PCI Core takes care of above mentioned, device-independent, jobs. The callbacks make use of PCI helper functions like pci_save/restore_state(), pci_enable/disable_device() and pci_set_power_state() to do required operations. In generic mode, they are no longer needed. Change function parameter in both .suspend() and .resume() to "struct device*" type. Use dev_get_drvdata() to get drv data. The .suspend() callback is invoking rt2x00lib_suspend() which needs to be modified as generic rt2x00pci_suspend() has no pm_message_t type argument, passed to it, which is required by it according to its declaration. Although this variable remained unused in the function body. Hence, remove it from the function definition & declaration. rt2x00lib_suspend() is also invoked by rt2x00usb_suspend() and rt2x00soc_suspend(). Thus, modify the functional call accordingly in their function body. Earlier, .suspend() & .resume() were exported and were used by the following drivers: - drivers/net/wireless/ralink/rt2x00/rt2400pci.c - drivers/net/wireless/ralink/rt2x00/rt2500pci.c - drivers/net/wireless/ralink/rt2x00/rt2800pci.c - drivers/net/wireless/ralink/rt2x00/rt61pci.c Now, we only need to bind "struct dev_pm_ops" variable to "struct pci_driver". Thus, make the callbacks static. Declare an "extern const struct dev_pm_ops" variable and bind PM callbacks to it. Now, export the variable instead and use it in respective drivers. Compile-tested only.

2020-08-02rtw88: 8821c: coex: add functions and parametersPing-Cheng Chen
Without this patch, RTL8821CE will not have coex support, and will crash the system because of the NULL pointers for the coex functions. While RTL8822C series are WiFi + BT combo chips, it needs the co-existence mechanism for the device to work on both WiFi and BT without interfering each other. And the coex support has already been added before, most of the mechanisms are implemented. The driver should just add corresponding functions to operate on different types of chips and its coex parameters.
