Currently, get_wireless_stats is racy by _design_. This is
because it returns a buffer, which needs to be statically
allocated since it cannot be freed if it was allocated
dynamically. Also, SIOCGIWSTATS and /proc/net/wireless use
no common lock, and /proc/net/wireless accesses are not
synchronised against each other. This is a design flaw in
get_wireless_stats since the beginning.
This patch fixes it by wrapping /proc/net/wireless accesses
with the RTNL so they are protected against each other and
SIOCGIWSTATS. The more correct method of fixing this would
be to pass in the buffer instead of returning it and have
the caller take care of synchronisation of the buffer, but
even then most drivers probably assume that their callback
is protected by the RTNL like all other wext callbacks.

mirror the mac80211 CONF_PS setting. When mac80211 turns off
CONF_PS we follow suit. This means that the user power level

iwlwifi internally needs to keep track of whether PS
is enabled in the firmware or not. To do this, it keeps
a bit in the status flags, called STATUS_POWER_PMI.
The code to set this bit looks as follows:
static int iwl_set_power(struct iwl_priv *priv, void *cmd)
{
return iwl_send_cmd_pdu_async(priv, POWER_TABLE_CMD,
sizeof(struct iwl_powertable_cmd),
cmd, NULL);
}
int iwl_power_update_mode(...)
{
[...]
if (final_mode != IWL_POWER_MODE_CAM)
set_bit(STATUS_POWER_PMI, &priv->status);
iwl_update_power_cmd(priv, &cmd, final_mode);
cmd.keep_alive_beacons = 0;
if (final_mode == IWL_POWER_INDEX_5)
cmd.flags |= IWL_POWER_FAST_PD;
ret = iwl_set_power(priv, &cmd);
if (final_mode == IWL_POWER_MODE_CAM)
clear_bit(STATUS_POWER_PMI, &priv->status);
else
set_bit(STATUS_POWER_PMI, &priv->status);
if (priv->cfg->ops->lib->update_chain_flags && update_chains)
priv->cfg->ops->lib->update_chain_flags(priv);
[...]
}
Now, this bit really needs to track what the _firmware_
thinks, not what the driver thinks. Therefore, there is
a race condition here -- the driver sets the bit before
it knows that the async command sent to the card in the
iwl_set_power function has been processed. As a result,
the call to update_chain_flags() may think that the card
has been woken up (PMI bit cleared) while in reality it
hasn't processed the async POWER_TABLE_CMD yet.
This leads to bugs -- any commands the update_chain_flags
function sends can get stuck and subsequent commands also
fail.
The fix is almost trivial: since there's no reason to send
an async command here (in fact, there almost never should
be since many mac80211 callbacks can sleep) just make the
function wait for the card to process the command and then
return and clear the PMI bit.

The call to ieee80211_hw_config() is supposed to apply changes
synchronously, so once it returns the parameters are applied to
the hardware. Thus, there really is no need to delay the probing
by the channel switch time again since the channel switch has
already happened once we get to this code.
Additionally, there is no need to wait for a NAV update (probe
delay) when the channel is passively scanned. Remove that extra
time too.
This cuts scanning time from over 7 seconds to under 4 on ar9170,
which is due to the number of channels scanned and ar9170's switch
time being advertised as 135ms (my test now indicates it is about
77ms with the current driver, but the difference might also be due
to using a different machine with different USB controllers).

Make ieee80211_drop_unencrypted() handle the special cases for MFP by

When using nl80211, we do not have a mechanism to set
sdata->drop_unencrypted. Currently, this breaks code that is supposed
to drop unencrypted frames when protection is expected since
ieee80211_rx_h_decrypt() is optimized to not set rx->key when the
frame is not protected.
This patch modifies ieee80211_rx_h_decrypt() to set rx->key for all
frames and only skip decryption if the frame is not protected. This
allows ieee80211_drop_unencrypted() to correctly drop frames even if
drop_unencrypted is not set.
The changes here are not enough to handle all cases, though. Additional
patches will be needed to implement proper IEEE 802.1X PAE for station
mode (currently, this is only used for AP mode) and some additional
rules are needed for MFP to drop unprotected Robust Action frames prior
to having PTK and IGTK configured.
In theory, the unprotected frames could and should be dropped in
ieee80211_rx_h_decrypt(). However, due to the special case with EAPOL
frames that have to be allowed to be received unprotected even when
keys are set, it is simpler to only set rx->key and allow the
ieee80211_frame_allowed() function to handle the actual dropping of
data frames after 802.11->802.3 header conversion. In addition,
unprotected robust management frames are dropped before they are
processed.

When a software scan starts, it first sets sw_scanning, but
leaves the scan_channel "unset" (it currently actually gets
initialised to a default). Now, when something else tries
to (re)configure the hardware in the window between these two
events (after sw_scanning = true, but before scan_channel is
set), the current code switches to the (unset!) scan_channel.
This causes trouble, especially when switching bands and
sending frames on the wrong channel.
To work around this, leave scan_channel initialised to NULL
and use it to determine whether or not a switch to a different
channel should occur (and also use the same condition to check
whether to adjust power for scan or not).
Additionally, avoid reconfiguring the hardware completely when
recalculating idle resulted in no changes, this was the problem
that originally led us to discover the race condition in the
first place, which was helpfully bisected by Pavel. This part
of the patch should not be necessary with the other fixes, but
not calling the ieee80211_hw_config function when we know it to
be unnecessary is certainly a correct thing to do.
Unfortunately, this patch cannot and does not fix the race
condition completely, but due to the way the scan code is
structured it makes the particular problem Pavel discovered
(race while changing channel at the same time as transmitting
frames) go away. To fix it completely, more work especially
with locking configuration is needed.
