However if an array is started 'readonly' (by writing 'readonly' to

mac80211 does not propagate failed hardware reconfiguration
requests. For suspend and resume this is important due to all
the possible issues that can come out of the suspend <-> resume
cycle. Not propagating the error means cfg80211 will assume
the resume for the device went through fine and mac80211 will
continue on trying to poke at the hardware, enable timers,
queue work, and so on for a device which is completley
unfunctional.

The least we can do is to propagate device start issues and
warn when this occurs upon resume. A side effect of this patch
is we also now propagate the start errors upon harware
reconfigurations (non-suspend), but this should also be desirable
anyway, there is not point in continuing to reconfigure a

be made to it until we resume and its start callback is kicked.
If such calls are made, however, suspend can end up throwing
hardware in an unexpected state and making the device unusable
upon resume.

Fix this by preventing mac80211 to schedule dynamic_ps_disable_work
by checking for when mac80211 starts to suspend and starts
quiescing. Frames should be allowed to go through though as
that is part of the quiescing steps and we do not flush the
mac80211 workqueue since it was already done towards the

It is not clear to me how the first "direct probe" here
happens, but this seems to be a race condition, if the
user requests to deauth after requesting assoc, but before
the assoc response is received. In that case, it may
happen that mac80211 tries to report the assoc success to
cfg80211, but gets blocked on the wdev lock that is held
because the user is requesting the deauth.

The result is that we run into a warning. This is mostly
harmless, but maybe cause an unexpected event to be sent
to userspace; we'd send an assoc success event although
userspace was no longer expecting that.

To fix this, remove the warning and check whether the
race happened and in that case abort processing.

Bob Copeland [Tue, 22 Dec 2009 03:26:48 +0000 (22:26 -0500)]
ath5k: fix SWI calibration interrupt storm

The calibration period is now invoked by triggering a software
interrupt from within the ISR by ath5k_hw_calibration_poll()
instead of via a timer.

However, the calibration interval isn't initialized before
interrupts are enabled, so we can have a situation where an
interrupt occurs before the interval is assigned, so the
interval is actually negative.  As a result, the ISR will
arm a software interrupt to schedule the tasklet, and then
rearm it when the SWI is processed, and so on, leading to a
softlockup at modprobe time.

Move the initialization order around so the calibration interval
is set before interrupts are active.  Another possible fix
is to schedule the tasklet directly from the poll routine,
but I think there are additional plans for the SWI.

This is because ucc_geth_tx() tries to process an empty queue when
queues are logically stopped. Stopping the queues doesn't disable
polling, and since nowadays ucc_geth_tx() is actually called from
the polling routine, the oops above might pop up.

Fix this by removing 'netif_queue_stopped() == 0' check.

ACPI: do not select ACPI_DOCK from ATA_ACPI

In March 2008 commit 0ac4a3c2fbbcadc3e96e4dc47d4ae802d66e6f67 ("ACPI: fix
ATA_ACPI build") made CONFIG_ACPI_DOCK be selected by CONFIG_ATA_ACPI because
of a build error when CONFIG_ATA_ACPI=y and CONFIG_ACPI_DOCK=m.

However, in September 2008 commit 898b054f3eec5921320ae8614b5bdd7b07ea5b43
("dock: make dock driver not a module") removed the possibility of having
CONFIG_ACPI_DOCK=m and therefore there is no need for selecting it when
CONFIG_ATA_ACPI=y.

This makes the kernel ~5 Kb smaller for people who don't have a dock by
allowing them to not have ACPI_DOCK compiled-in because of ATA_ACPI=y.
