mac80211: fix AP/VLAN PS buffer race

When an AP interface is removed without the
AP/VLAN interfaces having been removed before
already, the AP-VLAN interface might still
have sleeping stations and buffer multicast
frames which will happen on the AP interface.
Thus, we need to remove AP/VLAN interfaces
before purging buffered broadcast frames.

This leads to "interesting" bugs, because it
can't actually handle the interruptions; for

it will assume the command completed fully,
and then leave it pending, which leads to all
kinds of trouble when the command finishes
later.

Since there's no easy way to gracefully deal

interruptible waits.

13 years agoiwlagn: unmap cmd queue's tfds as BIDI
Emmanuel Grumbach [Thu, 15 Sep 2011 18:46:29 +0000 (11:46 -0700)]
iwlagn: unmap cmd queue's tfds as BIDI

If the driver is unloaded while there is still a host command in
flight, its tfd will be freed by iwl_tx_queue_free.
This function is called for both types of queues: Tx queues and cmd
queue. This didn't take in count the fact that in Tx queues, tfds are
mapped as TO_DEVICE (besides the first TB), whereas in cmd queue, all
TBs are mapped as BIDI.

Hence, tx_queue_free unmapped the second (and higher) TB of each tfd
in the cmd queue as TO_DEVICE, whereas they must be freed as BIDI.
This means that if a multi TFD is in flight while we unload the
driver (which is quite unlikely but can happen), we will get the
warning below.

This patch fixes this.
