In theory, it should always be set.

The first is in _internal_start_scan, when we queue up a scan; we first queue the worker, and then set priv->scan_req. There's theoretically a 50mS delay which should be plenty, but doing things that way just seems racy (and not in the good way). The second is in the scan worker thread itself. Depending on the state of priv->scan_channel, we cancel pending scan runs and then requeue a run in 300mS. We then send the scan command down to the hardware, sleep, and if we get scan results for all the desired channels, we set priv->scan_req to NULL. However, it that's happened in less than 300mS, what happens with the pending scan run? This patch addresses both of those concerns. With the patch applied, we have not seen the oops in the past two weeks. Signed-off-by: Andres Salomon <dilinger@queued.net> Cc: stable@kernel.org Signed-off-by: John W.

* | libertas: ensure we clean up a scan request properlyAndres Salomon2011-11-02
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 2e30168b ("libertas: terminate scan when stopping interface") adds cleanup code to lbs_eth_stop to call cfg80211_scan_done if there's an outstanding cfg80211_scan_request. However, it assumes that the scan request was allocated via the cfg80211 stack. Libertas has its own internal allocation method, kept track of with priv->internal_scan. This doesn't set scan_req->wiphy, amongst other things, which results in hitting a BUG() when we call cfg80211_scan_done on the request. This provides a function to take care of the low-level scan_req cleanup details. We simply call that to deal with finishing up scan requests. The bug we were hitting was: [ 964.321495] kernel BUG at net/wireless/core.h:87!

| * libertas: detect TX lockups and reset hardwareDaniel Drake2011-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent patches added support for resetting the SD8686 hardware when commands time out, which seems to happen quite frequently soon after resuming the system from a Wake-on-WLAN-triggered resume. At http://dev.laptop.org/ticket/10969 we see the same thing happen with transmits. In this case, the hardware will fail to respond to a frame passed for transmission, and libertas (correctly) will block all further commands and transmissions as the hardware can only deal with one thing at a time. This results in a lockup while the system waits indefinitely for the dead card to respond. Hook up a TX lockup timer to detect this and reset the hardware.

| * libertas: scan behaviour consistency improvementsDaniel Drake2011-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When scanning for the broadcast SSID, there is no need to add the SSID TLV (restoring the behaviour of the driver behaviour in the wext days, confirmed in Marvell specifications). If bssid is unspecified, the current scan code will usually fire off an active scan probing for the specific requested SSID. However, if a scan is ongoing (or has just finished), those scan results will be used instead (even if that scan is totally different, e.g. a passive scan on channel 4 for a different SSID). Fix this inconsistency by always firing off a scan when associating without a bssid. Signed-off-by: Daniel Drake <dsd@laptop.org> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally, the v9 firmware will be loaded if it's available. However, on OLPC XO-1 machines, the olpc-specific firmware supports extra functionality. This makes the libertas driver attempt to load the custom firmware first if the machine is an OLPC machine; if that fails (or it's not an OLPC machine), fall back to attempting to load the other firmwares. usb8388_olpc.bin is currently found in the linux-firmware repository.

| * libertas: disable functionality when interface is downDaniel Drake2011-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modify the driver so that it does not function when the interface is down, in preparation for runtime power management. No commands can be run while the interface is down, so the ndo_dev_stop routine now directly does all necessary work (including asking the device to disconnect from the network and disabling multicast functionality) directly. power_save and power_restore hooks are added meaning that card drivers can take steps to turn the device off when the interface is down. The MAC address can now only be changed when all interfaces are down; the new address will be programmed when an interface gets brought up. This matches mac80211 behaviour. Also, some small cleanups/simplifications were made in the surrounding device handling logic. Signed-off-by: Daniel Drake <dsd@laptop.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | | | Currently, "udevadm info -a -p /sys/class/net/wlan0" doesn't mention the usb8xxx or libertas driver anywhere. This makes writing udev rules a bit uncomfortable. Using the USB interface as the parent device corrects the hierarchy.

| * libertas: link mesh device to wiphyDaniel Drake2011-08-08
| | | | | | | | | | | | | | | | | | | | | | | | | | The mesh device is now exposed as an interface of the wiphy. This exposes the mesh device to the cfg80211 interface, allowing mesh channel selection to be reimplemented, and available to NetworkManager as it was before. Some header tweaking was needed in order to implement lbs_mesh_activated(). Signed-off-by: Daniel Drake <dsd@laptop.org> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the mesh was running whenever the appropriate hardware and firmware was present.

| * libertas: fix handling of command timeout, completion and interruptionDaniel Drake2011-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When commands time out, corruption ensues. As lbs_complete_command() is called without locking, the command node is mistakenly freed twice. Also fixed up locking here in a few other places. The nature of command timeout may be that the card didn't even acknowledge receipt of the request. Detect this case and reset dnld_sent so that other commands don't hang forever. When cmdnodes are moved between the free list and the pending list, their list heads should be reinitialized. Fixed this. Sometimes commands are completed without actually submitting them or removing them from cmdpendingq. We must remember to remove them from cmdpendingq in these cases, so handle this in lbs_complete_command(). Harmless signals generated during suspend/resume were interrupting lbs_cmd. Convert to an uninterruptible sleep to avoid this. lbs_thread must be woken up every time there is some new work to do. I found that when 2 commands are queued, ther completion of the first command would not wake up lbs_thread to submit the second. Poke lbs_thread at the end of lbs_complete_command() to fix this.

| * libertas: add sd8686 reset_card supportDaniel Drake2011-06-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | At http://dev.laptop.org/ticket/10748 we are seeing a case of the libertas firmware randomly stopping responding to commands after resume. Careful monitoring of communications indicates a firmware or hardware bug, which has been reported to Marvell. Work around this issue by adding a reset_card method; this is automatically called when command timeouts are detected and provides an instant recovery to this situation.
