ath6kl: Fix crash during the connection process · 9aa60357

Raja Mani authored Aug 04, 2011

Sometimes, the network manager is failing to connect to the AP due
to the below kernel crash message. The reason behind this,
after issuing the connect command to the chip, the chip is sending
disconnect event and then immediately one connect event to the host
in some random cases.

The host driver resets all states (including cfg80211 state machine)
when it receives disconnect event from the chip. But, still the host
driver reports the next received connect event to cfg80211, at that time
cfg80211 SME state would have been in IDLE state, which was causing
the below kernel crash.

Now, host driver's sme state machine is checked every time before
delivering connect event to cfg80211

ath6kl: change aggreation timeout message from an error to a debug message · 37ca6335

Kalle Valo authored Jul 21, 2011

When I connect to my Linksys WT610N AP supporting 11n I see a lot of
aggreation timeout errors:

[  408.885053] ath6kl: aggr timeout (st 3109 end 3140)
[  463.872108] ath6kl: aggr timeout (st 3671 end 3702)
[  495.010060] ath6kl: aggr timeout (st 3983 end 4014)

[  585.019067] ath6kl: aggr timeout (st 816 end 847)

But still the connection seems to work. To not clutter the logs change
the error message to a debug message. But add a fixme comment so that
this will be investigated.

ath6kl: fix crash when interface is closed but scan is ongoing · 6fd1eace

Kalle Valo authored Jul 21, 2011

When ath6kl module was removed while a scan was ongoing the driver would
crash in ath6kl_cfg80211_scan_complete_event().

Fix the function not to iterate nodes when the scan is aborted. The nodes
are already freed when the module is being unloaded. This patch removes the
null check entirely as the wmi structure is not accessed anymore during
module unload.

Also fix a bug where the status was checked as a bitfield with '&' operator.
But it's not a bitfield, just a regular error code.

This is a port of my patch from ath6kl staging with the same title.

Kalle Valo authored Jul 21, 2011

ath6kl_cfg80211_scan_node() was calling cfg80211_inform_bss_frame()
with CFP_KERNEL but the function is executed with a spin lock taken.
This is wrong and the function must use GFP_ATOMIC instead.

ath6kl: don't force foreground scan when connected · b2c76bbe

Kalle Valo authored Jul 21, 2011

In my setup data transfer stalls when there's data transmission during
scan. After some testing I found out that using background scan
when connected to makes the problem go away. This is more like
a workaround than a proper fix, but as the stall is so severe the
workaround is justified.

With a dual band card this increases scan time when connected from
1.9s to 4.4s. When not connected the scan time is not affected and
is the same 1.9s.
