Alexander Bondar 752096727c iwlwifi: mvm: Add and examine TLV flag for P2P client uAPSD support
Current firmware doesn't handle well uAPSD in P2P Client.
When it will be fixed, the firmware will set a TLV flag to notify
the driver that uAPSD is supported in P2P client mode.
Check this flag when sending power command for P2P client.

Arik Nemtsov 2a988e9808 iwlwifi: trans: prevent reprobe on repeated FW errors before restart
In case a sync command timeouts or Tx is stuck while a FW error
interrupt arrives, we might call iwl_op_mode_nic_error twice before
a restart has been initiated. This will cause a reprobe. Unify calls
to this function at the transport level and only call it on the first
FW error in a given by checking the transport FW error flag.

While at it, remove the privately defined iwl_nic_error from PCIE code
and use the common callback instead.

mesh_sync_offset_adjust_tbtt()  was assuming that the

Save a pointer to the meshconf IE in the beacon_data (this
works because both the IE pointer and beacon buffer are

Johannes Berg 1ddbbb0c83 iwlwifi: mvm: use pre-RCU-sync sta removal operation
iwlmvm relies on the current mac80211 behaviour of allowing
station pointers to be valid for an RCU grace period after
returning from the sta_state() callback. To optimise these
cases, this behaviour is going away, so make the driver use
the new sta_pre_rcu_remove() method to clear the pointer in
the fw_id_to_mac_id[] array.

Since this may happen while the station is still present in
the firmware, don't set the pointer to NULL but to -ENOENT
to mark this particular case. In client mode, the station
is kept even longer (until marking the MAC as unassociated)
so the drain flow must take this new behavior into account.

Johannes Berg 6a9d1b91f3 mac80211: add pre-RCU-sync sta removal driver operation
Currently, mac80211 allows drivers to keep RCU-protected station
references that are cleared when the station is removed from the
driver and consequently needs to synchronize twice, once before
removing the station from the driver (so it can guarantee that
the station is no longer used in TX towards the driver) and once
after the station is removed from the driver.

Add a new pre-RCU-synchronisation station removal operation to
the API to allow drivers to clear/invalidate their RCU-protected
station pointers before the RCU synchronisation.

This will allow removing the second synchronisation by changing
the driver API so that the driver may no longer assume a valid
RCU-protected pointer after sta_remove/sta_state returns.

The alternative to this would be to synchronize_rcu() in all the
drivers that currently rely on this behaviour (only iwlmvm) but
that would defeat the purpose.

Jeff Kirsher 8232f1f3d0 rfkill: Fix FSF address in file headers
Several files refer to an old address for the Free Software Foundation
in the file header comment.  Resolve by replacing the address with
the URL <http://www.gnu.org/licenses/> so that we do not have to keep
updating the header comments anytime the address changes.
