but task is already holding lock:
 (rtnl_mutex){+.+.+.}, at: [<ffffffff81400ff2>] rtnl_lock+0x12/0x20

which lock already depends on the new lock.

the existing dependency chain (in reverse order) is:

obvious. I'm not entirely sure which code paths lead
here, so until I can analyse it better let's just use
RCU to avoid the problem.

iwlwifi: fix up command sending

The current command sending in iwlwifi is a bit of a mess:
 1) there is a struct, iwl_cmd, that contains both driver
    and device data in a single packed structure -- this
    is very confusing
 2) the on-stack data and the command metadata share a
    structure by embedding the latter in the former, which
    is also rather confusing because it leads to weird
    unions and similarly odd constructs
 3) each txq always has enough space for 256 commands,
    even if only 32 end up being used

This patch fixes these things:
 1) rename iwl_cmd to iwl_device_cmd and keep track of
    command metadata and device command separately, in
    two arrays in each tx queue
 2) remove the 'meta' member from iwl_host_cmd and only
    put in the required members
 3) allocate the cmd/meta arrays separately instead of
    embedding them into the txq structure

Luis R. Rodriguez [Thu, 23 Jul 2009 23:37:47 +0000]
mac80211: fix MLME issuing of probe requests while scanning

We were issuing probe requests to the associated AP on the wrong
band by having our beacon timer loss trigger while we are scanning.
When we would scan the timer could hit and force us to send a
probe request to the AP but with a chance we'd be on the wrong band.

This leads to finding no usable bitrate but we should not get so
far on the xmit path. We should not be trying to send these probe
request frames so prevent ieee80211_mgd_probe_ap() from sending
these.

As it turns out all callers of ieee80211_mgd_probe_ap() need this
check so we just move the scan check there. This means we can remove
the recenlty added check during ieee80211_sta_monitor_work().

Additionally we now fix a race condition added by the patch
"mac80211: do not monitor the connection while scanning" which
had the same check in ieee80211_sta_conn_mon_timer(). The race
happens because the timer routine *does* a valid check for
scanning but after it queues work into the mac80211 workqueue
the work callback can kick off with scanning enabled and cause
the same issue we were trying to avoid.

The more appropriate solution would be to disable the respective
timers during scan and re-enable them after scan but requires more
complex code and testing.

Helmut Schaa [Thu, 23 Jul 2009 11:18:01 +0000]
mac80211: implement basic background scanning

Introduce a new scan flag "SCAN_OFF_CHANNEL" which basically tells us
that we are currently on a different channel for scanning and cannot
RX/TX. "SCAN_SW_SCANNING" tells us that we are currently running a
software scan but we might as well be on the operating channel to RX/TX.
While "SCAN_SW_SCANNING" is set during the whole scan "SCAN_OFF_CHANNEL"
is set when leaving the operating channel and unset when coming back.

Introduce two new scan states "SCAN_LEAVE_OPER_CHANNEL" and
"SCAN_ENTER_OPER_CHANNEL" which basically implement the functionality we
need to leave the operating channel (send a nullfunc to the AP and stop
the queues) and enter it again (send a nullfunc to the AP and start the
queues again).

Enhance the scan state "SCAN_DECISION" to switch back to the operating
channel after each scanned channel. In the future it sould be simple
to enhance the decision state to scan as much channels in a row as the
qos latency allows us.

cfg80211: make aware of net namespaces

In order to make cfg80211/nl80211 aware of network namespaces,
we have to do the following things:

 * del_virtual_intf method takes an interface index rather
   than a netdev pointer - simply change this

 * nl80211 uses init_net a lot, it changes to use the sender's
   network namespace

 * scan requests use the interface index, hold a netdev pointer
   and reference instead

 * we want a wiphy and its associated virtual interfaces to be
   in one netns together, so
    - we need to be able to change ns for a given interface, so
      export dev_change_net_namespace()
    - for each virtual interface set the NETIF_F_NETNS_LOCAL
      flag, and clear that flag only when the wiphy changes ns,
      to disallow breaking this invariant

 * when a network namespace goes away, we need to reparent the
   wiphy to init_net

 * cfg80211 users that support creating virtual interfaces must
   create them in the wiphy's namespace, currently this affects
   only mac80211

The end result is that you can now switch an entire wiphy into
a different network namespace with the new command
iw phy#<idx> set netns <pid>
and all virtual interfaces will follow (or the operation fails).

There are still two places in mac80211 that hardcode
the initial net namespace (init_net). One of them is
mandated by cfg80211 and will be removed by a separate
patch, the other one is used for finding the network
device of a pending packet via its ifindex.

Remove the latter use by keeping track of the device
pointer itself, via the vif pointer, and avoid it
going stale by dropping pending frames for a given
interface when the interface is removed.

To keep track of the vif pointer for the correct
interface, change the info->control.vif pointer's
internal use to always be the correct vif, and only
move it to the vif the driver expects (or NULL for
monitor interfaces and injected packets) right before
giving the packet to the driver.

10 years agoigb: add completion timeout workaround for 82575/82576

igb: add completion timeout workaround for 82575/82576

The 82575 and 82576 hardware can both experience data corruption issues if
a pci-e completion arrives after the timeout value.  In order to avoid this
we need to increase the timeout value while pci-e master is disabled.
