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 possible NULL dereference
|
|
|
|
|
|
|
|
|
|
|
|
If chanctx is missing on a given vif then the band
|
|
|
|
|
|
is assumed to be 2GHz. However if hw doesn't
|
|
|
|
|
|
support 2GHz band then mac80211 ended up with a
|
|
|
|
|
|
NULL dereference.
|
|
|
|
|
|
|
|
|
|
|
|
This fixes a splat:

"mac80211: fix WPA with VLAN on AP side with ps-sta"

"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.

cfg80211: remove racy beacon_interval assignment

|
|
In case of AP mode, the beacon interval is already reset to

zero inside cfg80211_stop_ap(), and in the other modes it
|
|
|
|

isn't relevant. Remove the assignment to remove a potential

|
|
|
race since the assignment isn't properly locked.

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:

ath9k: fix ps-poll responses under a-mpdu sessions
|
|
|
|
|
|
|
|
|
|
|
|
When passing tx frames to the U-APSD queue for powersave poll responses,
|
|
|
|
|
|
the ath_atx_tid pointer needs to be passed to ath_tx_setup_buffer for
|
|
|
|
|
|
proper sequence number accounting.
|
|
|
|
|
|
|
|
|
|
|
|
This fixes high latency and connection stability issues with ath9k
|
|
|
|
|
|
running as AP and a few kinds of mobile phones as client, when PS-Poll
|
|
|
|
|
|
is heavily used

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.

|
|
|
|
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: Calculate IQ-CAL median
|
|
|
|
|
|
|
|
|
|
|
|
This patch adds a routine to calculate the median IQ correction
|
|
|
|
|
|
values for AR955x, which is used for outlier detection.
|
|
|
|
|
|
The normal method which is used for all other chips is
|
|
|
|
|
|
bypassed for AR955x.

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.

In chips like AR955x, the initvals contain the information

whether IQ calibration is to be done in the HW when an

|
|
|
|
|
AGC calibration is triggered. Check if IQ-CAL is enabled

|
|

in the initvals before flagging 'txiqcal_done' as true.

ath9k: Fix TX power calculation

fixed the incorrect values in the eeprom templates, but if

boards have already been calibrated with incorrect values,

they would still be using the wrong TX power. Fix this by assigning

a default value in such cases.

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: send ibss probe responses with noack flag

|
|
|
|
|
|
|

Responding to probe requests for scanning clients will often create

excessive retries, as it happens quite often that the scanning client

|
already left the channel. Therefore do it like hostapd and send probe

|
|
responses for wildcard SSID only once by using the noack flag.

The ieee80211_vif_use_channel() function calls
|
|
|
|
|
|
ieee80211_vif_release_channel(), so there's no need to call it
|
|
|
|
|
|
explicitly in __ieee80211_sta_join_ibss().

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.

sdata->u.ap.request_smps_work can’t be flushed synchronously

stopped to its default: OFF.

cfg80211: re-enable 5/10 MHz support

Unfortunately I forgot this during the merge window, but the

|
|
|
|
|
|

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.

mac80211: add length check in ieee80211_is_robust_mgmt_frame()
|
|
|
|
|
|
|
|
|
|
|
|
A few places weren't checking that the frame passed to the
|
|
|
|
|
|
function actually has enough data even though the function
|
|
|
|
|
|
clearly documents it must have a payload byte. Make this
|
|
|
|
|
|
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.

If there's a policy, then nla_parse() return values must be

checked, otherwise the policy is useless and there's nothing
|

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).
