ath9k_hw: remove ANI function restrictions for AP mode
|
||
|
||
The primary purpose of this piece of code was to selectively disable
|
||
OFDM weak signal detection. The checks for this are elsewhere, and an
|
||
earlier commit relaxed the restrictions for older chips, which are more
|
||
sensitive to interference.

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.

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.

ath9k: fix invalid descriptor discarding
|
||
|
||
Only set sc->rx.discard_next to rx_stats->rs_more when actually
|
||
discarding the current descriptor.
|
||
|
||
Also, fix a detection of broken descriptors:
|
||
First the code checks if the current descriptor is not done.
|
||
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.
|
||
|
||
This fixes a regression introduced in

ath9k: make some hardware reset log messages debug-only

|
||
On some chips, baseband watchdog hangs are more common than others, and

the driver has support for handling them.

Interrupts even after a watchdog hang are also quite common, so there's

not much point in spamming the user's logfiles.

ath9k: do not set half/quarter channel flags in AR_PHY_MODE
|
||
|
||
5/10 MHz channel bandwidth is configured via the PLL clock, instead of
|
||
the AR_PHY_MODE register. Using that register is AR93xx specific, and
|
||
makes the mode incompatible with earlier chipsets.
|
||
|
||
In some early versions, these flags were apparently applied at the wrong
|
||
point in time and thus did not cause connectivity issues, however now
|
||
they are causing problems, as pointed out in this OpenWrt ticket:

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.

cfg80211: bugfix in regulatory user hint process
|
||
|
||
After processing hint_user, we would want to schedule the
|
||
timeout work only if we are actually waiting to CRDA. This happens
|
||
when the status is not "IGNORE" nor "ALREADY_SET".

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
|
||
of AGC calibration once, it is triggered 3 times and
|
||
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: move csa_active setting in STA CSA
|
||
|
||
The sdata->vif.csa_active could be left set after,
|

e.g. channel context constraints check fail in STA
|
||
mode leaving the interface in a strange state for
|
||
a brief period of time until it is disconnected.
|

This was harmless but ugly.

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.

cfg80211: fix scan done race
|
||
|
||
When an interface/wdev is removed, any ongoing scan should be
|
||
cancelled by the driver. This will make it call cfg80211, which
|
||
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.

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.

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.

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).
