2020-07-31crypto: ccp - 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.

However, given that any additional bytes that we copy will be ignored anyway, we can simply copy XTS_BLOCK_SIZE unconditionally, which means we can use struct assignment of the array members instead, which is likely to be more efficient as well.

2020-07-31mac80211: improve AQL tx airtime estimationFelix Fietkau
AQL does not take into account that most HT/VHT/HE traffic is A-MPDU aggregated. Because of that, the per-packet airtime overhead is vastly overestimated. Improve it by assuming an average aggregation length of 16 for non-legacy traffic if not using the VO AC queue. This should improve performance with high data rates, especially with multiple stations Signed-off-by: Felix Fietkau <nbd@nbd.name> Link: https://lore.kernel.org/r/20200724182816.18678-1-nbd@nbd.name Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2020-07-31cfg80211/mac80211: add connected to auth server to meshconfMarkus Theil
Besides information about num of peerings and gate connectivity, the mesh formation byte also contains a flag for authentication server connectivity, that currently cannot be set in the mesh conf. This patch adds this capability, which is necessary to implement 802.1X authentication in mesh mode.

2020-07-31cfg80211/mac80211: add mesh_param "mesh_nolearn" to skip path discoveryLinus Lüssing
Currently, before being able to forward a packet between two 802.11s nodes, both a PLINK handshake is performed upon receiving a beacon and then later a PREQ/PREP exchange for path discovery is performed on demand upon receiving a data frame to forward. When running a mesh protocol on top of an 802.11s interface, like batman-adv, we do not need the multi-hop mesh routing capabilities of 802.11s and usually set mesh_fwding=0. However, even with mesh_fwding=0 the PREQ/PREP path discovery is still performed on demand. Even though in this scenario the next hop PREQ/PREP will determine is always the direct 11s neighbor node. The new mesh_nolearn parameter allows to skip the PREQ/PREP exchange in this scenario, leading to a reduced delay, reduced packet buffering and simplifies HWMP in general. mesh_nolearn is still rather conservative in that if the packet destination is not a direct 11s neighbor, it will fall back to PREQ/PREP path discovery. For normal, multi-hop 802.11s mesh routing it is usually not advisable to enable mesh_nolearn as a transmission to a direct but distant neighbor might be worse than reaching that same node via a more robust / higher throughput etc. multi-hop path.

2020-07-31cfg80211: allow the low level driver to flush the BSS tableEmmanuel Grumbach
The low level driver adds its own opaque information in the BSS table in the cfg80211_bss structure. The low level driver may need to signal that this information is no longer relevant and needs to be recreated. Add an API to allow the low level driver to do that. iwlwifi needs this because it keeps there an information about the firmware's internal clock. This is kept in mac80211's struct ieee80211_bss::sync_device_ts. This information is populated while we scan, we add the internal firmware's clock to each beacon which allows us to program the firmware correctly after association so that it'll know when (in terms of its internal clock) the DTIM and TBTT will happen. When the firmware is reset this internal clock is reset as well and ieee80211_bss::sync_device_ts is no longer accurate. iwlwifi will call this new API any time the firmware is started.

Since commit 5fe231e87372 ("cfg80211: vastly simplify locking"), the 'unlock' label at the end of 'nl80211_trigger_scan()' is useless and misleading, because nothing is unlocked there. Direct return can be used instead of 'err = -<error code>; goto unlock;' construction. Remove this label and simplify code accordingly.
