ath9k: Fix sequence number assignment for non-data frames
Since commit 558ff225de80ac95b132d3a115ddadcd64498b4f (ath9k: fix
ps-poll responses under a-mpdu sessions) non-data frames would have
gotten a sequence number from a TIDs sequence counter instead of
using the global sequence counter.
This can lead to instable connections.
To fix this only select the correct TID if we are processing a
data frame. Furthermore, prevent non-data frames to get a sequence
number from a TID sequence counter by adding a check to
ath_tx_setup_buffer.

ath9k_hw: set ANI firstep as absolute values instead of relative
On older chips, the INI value differ in similar ways as cycpwr_thr1, so
convert it to absolute values as well.
Since the ANI algorithm is different here compared to the old
implementation (fewer steps, controlled at a different point in time),
it makes sense to use values similar to what would be applied for newer
chips, just without relying on INI defaults.

ath9k_hw: set ANI cycpwr_thr1 as absolute values instead of relative
The table was copied from the ANI implementation of AR9300. It assumes
that the INI values contain a baseline value that is usable as reference
from which to increase/decrease based on the noise immunity value.
On older chips, the differences are bigger and especially AR5008/AR9001
are configured to much more sensitive values than what is useful.
Improve ANI behavior by reverting to the absolute values used in the
previous implementation (expressed as a simple formula instead of the
old table).

ath9k: fix ready time of the multicast buffer queue
qi->tqi_readyTime is written directly to registers that expect
microseconds as unit instead of TU.
When setting the CABQ ready time, cur_conf->beacon_interval is in TU, so
convert it to microseconds before passing it to ath9k_hw.
This should hopefully fix some Tx DMA issues with buffered multicast
frames in AP mode.

mac80211: fix WPA with VLAN on AP side with ps-sta again
commit de74a1d9032f4d37ea453ad2a647e1aff4cd2591
"mac80211: fix WPA with VLAN on AP side with ps-sta"
fixed an issue where queued multicast packets would
be sent out encrypted with the key of an other bss.
commit "7cbf9d017dbb5e3276de7d527925d42d4c11e732"
"mac80211: fix oops on mesh PS broadcast forwarding"
essentially reverted it, because vif.type cannot be AP_VLAN
due to the check to vif.type in ieee80211_get_buffered_bc before.
As the later commit intended to fix the MESH case, fix it
by checking for IFTYPE_AP instead of IFTYPE_AP_VLAN.

ath9k_hw: tweak noise immunity thresholds for older chipsets
Older chipsets are more sensitive to high PHY error counts, and the
current noise immunity thresholds were based on tests run at QCA with
newer chipsets.
This patch brings back the values from the old ANI implementation for
old chipsets, and it also disables weak signal detection on an earlier
noise immunity level, to improve overall radio stability on affected
devices.

ath9k_hw: toggle weak signal detection in AP mode on older chipsets
The commit 80b4205b "ath9k: Fix OFDM weak signal detection for AP mode"
prevented weak signal detection changes from taking effect in AP mode on
all chipsets, claiming it is "not allowed".
The main reason for not disabling weak signal detection in AP mode is
that typically beacon RSSI is used to track whether it is needed to
boost range, and this is unavailable in AP mode for obvious reasons.
The problem with not disabling weak signal detection is that older
chipsets are very sensitive to high PHY error counts. When faced with
heavy noise, this can lead to an excessive amount of "Failed to stop
TX DMA" errors in the field.

Also, fix a detection of broken descriptors:

Then it checks if the next descriptor is done.
Add a check that afterwards checks the first descriptor again, because
it might have been completed in the mean time.

5/10 MHz channel bandwidth is configured via the PLL clock, instead of

In some early versions, these flags were apparently applied at the wrong

mac80211: fix station wakeup powersave race
Consider the following (relatively unlikely) scenario:
1) station goes to sleep while frames are buffered in driver
2) driver blocks wakeup (until no more frames are buffered)
3) station wakes up again
4) driver unblocks wakeup
In this case, the current mac80211 code will do the following:
1) WLAN_STA_PS_STA set
2) WLAN_STA_PS_DRIVER set
3) - nothing -
4) WLAN_STA_PS_DRIVER cleared
As a result, no frames will be delivered to the client, even
though it is awake, until it sends another frame to us that
triggers ieee80211_sta_ps_deliver_wakeup() in sta_ps_end().
Since we now take the PS spinlock, we can fix this while at
the same time removing the complexity with the pending skb
queue function. This was broken since my commit 50a9432daeec
("mac80211: fix powersaving clients races") due to removing
the clearing of WLAN_STA_PS_STA in the RX path.
While at it, fix a cleanup path issue when a station is
removed while the driver is still blocking its wakeup.

mac80211: insert stations before adding to driver
There's a race condition in mac80211 because we add stations
to the internal lists after adding them to the driver, which
means that (for example) the following can happen:
1. a station connects and is added
2. first, it is added to the driver
3. then, it is added to the mac80211 lists
If the station goes to sleep between steps 2 and 3, and the
firmware/hardware records it as being asleep, mac80211 will
never instruct the driver to wake it up again as it never
realized it went to sleep since the RX path discarded the
frame as a "spurious class 3 frame", no station entry was
present yet.
Fix this by adding the station in software first, and only
then adding it to the driver. That way, any state that the
driver changes will be reflected properly in mac80211's
station state. The problematic part is the roll-back if the
driver fails to add the station, in that case a bit more is
needed. To not make that overly complex prevent starting BA
sessions in the meantime.

mac80211: fix AP powersave TX vs. wakeup race
There is a race between the TX path and the STA wakeup: while
a station is sleeping, mac80211 buffers frames until it wakes
up, then the frames are transmitted. However, the RX and TX
path are concurrent, so the packet indicating wakeup can be
processed while a packet is being transmitted.
This can lead to a situation where the buffered frames list
is emptied on the one side, while a frame is being added on
the other side, as the station is still seen as sleeping in
the TX path.
As a result, the newly added frame will not be send anytime
soon. It might be sent much later (and out of order) when the
station goes to sleep and wakes up the next time.
Additionally, it can lead to the crash below.
Fix all this by synchronising both paths with a new lock.
Both path are not fastpath since they handle PS situations.
In a later patch we'll remove the extra skb queue locks to
reduce locking overhead.

rtl8187: fix regression on MIPS without coherent DMA
This patch fixes regression caused by commit a16dad77634 "MIPS: Fix
potencial corruption". That commit fixes one corruption scenario in
cost of adding another one, which actually start to cause crashes
on Yeeloong laptop when rtl8187 driver is used.
For correct DMA read operation on machines without DMA coherence, kernel
have to invalidate cache, such it will refill later with new data that
device wrote to memory, when that data is needed to process. We can only
invalidate full cache line. Hence when cache line includes both dma
buffer and some other data (written in cache, but not yet in main
memory), the other data can not hit memory due to invalidation. That
happen on rtl8187 where struct rtl8187_priv fields are located just
before and after small buffers that are passed to USB layer and DMA
is performed on them.
To fix the problem we align buffers and reserve space after them to make
them match cache line.
This patch does not resolve all possible MIPS problems entirely, for
that we have to assure that we always map cache aligned buffers for DMA,
what can be complex or even not possible. But patch fixes visible and
reproducible regression and seems other possible corruptions do not
happen in practice, since Yeeloong laptop works stable without rtl8187
driver.

ath9k: Modify IQ calibration for AR955x
IQ calibration post-processing for AR955x is different
from other chips - instead of just doing it as part

a median is determined. This patch adds initial support
for changing the calibration behavior for AR955x.
Also, to simplify things, a helper routine to issue/poll
AGC calibration is used.
For non-AR955x chips, the iqcal_idx (which will be used
in subsequent patches) is set to zero.

cfg80211: consider existing DFS interfaces
It was possible to break interface combinations in
the following way:
combo 1: iftype = AP, num_ifaces = 2, num_chans = 2,
combo 2: iftype = AP, num_ifaces = 1, num_chans = 1, radar = HT20
With the above interface combinations it was
possible to:
step 1. start AP on DFS channel by matching combo 2
step 2. start AP on non-DFS channel by matching combo 1
This was possible beacuse (step 2) did not consider
if other interfaces require radar detection.
The patch changes how cfg80211 tracks channels -
instead of channel itself now a complete chandef
is stored.

cfg80211: fix channel configuration in IBSS join
When receiving an IBSS_JOINED event select the BSS object
based on the {bssid, channel} couple rather than the bssid
only.
With the current approach if another cell having the same
BSSID (but using a different channel) exists then cfg80211
picks up the wrong BSS object.
The result is a mismatching channel configuration between
cfg80211 and the driver, that can lead to any sort of
problem.
The issue can be triggered by having an IBSS sitting on
given channel and then asking the driver to create a new
cell using the same BSSID but with a different frequency.
By passing the channel to cfg80211_get_bss() we can solve
this ambiguity and retrieve/create the correct BSS object.
All the users of cfg80211_ibss_joined() have been changed
accordingly.
Moreover WARN when cfg80211_ibss_joined() gets a NULL
channel as argument and remove a bogus call of the same
function in ath6kl (it does not make sense to call
cfg80211_ibss_joined() with a zero BSSID on ibss-leave).

mac80211: fix bufferable MMPDU RX handling
Action, disassoc and deauth frames are bufferable, and as such don't
have the PM bit in the frame control field reserved which means we
need to react to the bit when receiving in such a frame.
Fix this by introducing a new helper ieee80211_is_bufferable_mmpdu()
and using it for the RX path that currently ignores the PM bit in
any non-data frames for doze->wake transitions, but listens to it in
all frames for wake->doze transitions, both of which are wrong.
Also use the new helper in the TX path to clean up the code.

mac80211: fix fragmentation code, particularly for encryption
The "new" fragmentation code (since my rewrite almost 5 years ago)
erroneously sets skb->len rather than using skb_trim() to adjust
the length of the first fragment after copying out all the others.
This leaves the skb tail pointer pointing to after where the data
originally ended, and thus causes the encryption MIC to be written
at that point, rather than where it belongs: immediately after the
data.
The impact of this is that if software encryption is done, then
a) encryption doesn't work for the first fragment, the connection
becomes unusable as the first fragment will never be properly
verified at the receiver, the MIC is practically guaranteed to
be wrong
b) we leak up to 8 bytes of plaintext (!) of the packet out into
the air
This is only mitigated by the fact that many devices are capable
of doing encryption in hardware, in which case this can't happen
as the tail pointer is irrelevant in that case. Additionally,
fragmentation is not used very frequently and would normally have
to be configured manually.
Fix this by using skb_trim() properly.

cfg80211: send scan results from work queue
Due to the previous commit, when a scan finishes, it is in theory
possible to hit the following sequence:
1. interface starts being removed
2. scan is cancelled by driver and cfg80211 is notified
3. scan done work is scheduled
4. interface is removed completely, rdev->scan_req is freed,
event sent to userspace but scan done work remains pending
5. new scan is requested on another virtual interface
6. scan done work runs, freeing the still-running scan
To fix this situation, hang on to the scan done message and block
new scans while that is the case, and only send the message from
the work function, regardless of whether the scan_req is already
freed from interface removal. This makes step 5 above impossible
and changes step 6 to be
5. scan done work runs, sending the scan done message
As this can't work for wext, so we send the message immediately,
but this shouldn't be an issue since we still return -EBUSY.

only queues a work struct. If interface/wdev removal is quick
enough, this can leave the scan request pending and processed
only after the interface is gone, causing a use-after-free.
Fix this by making sure the scan request is not pending after
the interface is destroyed. We can't flush or cancel the work
item due to locking concerns, but when it'll run it shouldn't
find anything to do. This leaves a potential issue, if a new
scan gets requested before the work runs, it prematurely stops
the running scan, potentially causing another crash. I'll fix
that in the next patch.
This was particularly observed with P2P_DEVICE wdevs, likely
because freeing them is quicker than freeing netdevs.

mac80211: avoid deadlock revealed by lockdep
sdata->u.ap.request_smps_work can’t be flushed synchronously
under wdev_lock(wdev) since ieee80211_request_smps_ap_work
itself locks the same lock.
While at it, reset the driver_smps_mode when the ap is
stopped to its default: OFF.
This solves:

nl80211: Reset split_start when netlink skb is exhausted
When the netlink skb is exhausted split_start is left set. In the
subsequent retry, with a larger buffer, the dump is continued from the
failing point instead of from the beginning.
This was causing my rt28xx based USB dongle to now show up when
running "iw list" with an old iw version without split dump support.

mac80211: move roc cookie assignment earlier
ieee80211_start_roc_work() might add a new roc
to existing roc, and tell cfg80211 it has already
started.
However, this might happen before the roc cookie
was set, resulting in REMAIN_ON_CHANNEL (started)
event with null cookie. Consequently, it can make
wpa_supplicant go out of sync.
Fix it by setting the roc cookie earlier.

nl80211: send event when AP operation is stopped
There are a few cases, e.g. suspend, where an AP interface is
stopped by the kernel rather than by userspace request, most
commonly when suspending. To let userspace know about this,
send the NL80211_CMD_STOP_AP command as an event every time
an AP interface is stopped. This also happens when userspace
did in fact request the AP stop, but that's not a problem.
For full-MAC drivers this may need to be extended to also
cover cases where the device stopped the AP operation for
some reason, this a bit more complicated because then all
cfg80211 state also needs to be reset; such API is not part
of this patch.

A few places weren't checking that the frame passed to the

safer by changing the function to take an skb and checking
the length inside. The old version is preserved for now as
the rtl* drivers use it and don't have a correct skb.

nl80211: fix scheduled scan RSSI matchset attribute confusion
The scheduled scan matchsets were intended to be a list of filters,
with the found BSS having to pass at least one of them to be passed
to the host. When the RSSI attribute was added, however, this was
broken and currently wpa_supplicant adds that attribute in its own
matchset; however, it doesn't intend that to mean that anything
that passes the RSSI filter should be passed to the host, instead
it wants it to mean that everything needs to also have higher RSSI.
This is semantically problematic because we have a list of filters
like [ SSID1, SSID2, SSID3, RSSI ] with no real indication which
one should be OR'ed and which one AND'ed.
To fix this, move the RSSI filter attribute into each matchset. As
we need to stay backward compatible, treat a matchset with only the
RSSI attribute as a "default RSSI filter" for all other matchsets,
but only if there are other matchsets (an RSSI-only matchset by
itself is still desirable.)
To make driver implementation easier, keep a global min_rssi_thold
for the entire request as well. The only affected driver is ath6kl.
I found this when I looked into the code after Raja Mani submitted
a patch fixing the n_match_sets calculation to disregard the RSSI,
but that patch didn't address the semantic issue.

mac80211: send {ADD,DEL}BA on AC_VO like other mgmt frames, as per spec
ATM, {ADD,DEL}BA and BAR frames are sent on the AC matching the TID of
the BA parameters. In the discussion [1] about this patch, Johannes
recalled that it fixed some races with the DELBA and indeed this
behavior was introduced in [2].
While [2] is right for the BARs, the part queueing the {ADD,DEL}BAs on
their BA params TID AC violates the spec and is more a workaround for
some drivers. Helmut expressed some concerns wrt such drivers, in
particular DELBAs in rt2x00.
ATM, DELBAs are sent after a driver has called (hence "purposely")
ieee80211_start_tx_ba_cb_irqsafe and Johannes and Emmanuel gave some
details wrt intentions behind the split of the IEEE80211_AMPDU_TX_STOP_*
given to the driver ampdu_action supposed to call this function, which
could prove handy to people trying to do the right thing in faulty
drivers (if their fw/hw don't get in their way).
