* ath5k: Fix surveyBruno Randolf2010-12-162-12/+25
| | | | | | | | | | | | | | The old survey implementation was broken and returned nonsense data. Clear cycle counters and survey data on reset. Since the cycle counters easily overflow it's better to keep a local version of collected survey data (in ms resolution, instead of clockrate) and update this every time survey is retrieved. If survey is retrieved often enough to avoid cycle counter overflows this works fine, otherwise we could update survey more often, like ath9k does. Still only the survey for the current channel is kept. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* cfg80211: fix null pointer dereference with a custom regulatory requestLuis R. Rodriguez2010-12-162-2/+5

When this happens and we are loading a driver with a custom regulatory request like all Atheros drivers we end up with a NULL pointer dereference. We fix this by checking if the request was a custom one.

| | | | | | | | | | | | | | | | | | | | Add a new notification to indicate that a received, unprotected Deauthentication or Disassociation frame was dropped due to management frame protection being in use. This notification is needed to allow user space (e.g., wpa_supplicant) to implement SA Query procedure to recover from association state mismatch between an AP and STA. This is needed to avoid getting stuck in non-working state when MFP (IEEE 802.11w) is used and a protected Deauthentication or Disassociation frame is dropped for any reason. After that, the station would silently discard any unprotected Deauthentication or Disassociation frame that could be indicating that the AP does not have association for the STA (when the Reason Code would be 6 or 7). IEEE Std 802.11w-2009, 11.13 describes this recovery mechanism. Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>

To fix the issue, implement per AC queues, which are emptied in priority order to the firmware. To keep it relatively simple, maintain a global buffer count and global queue stop/wake instead of per-AC. With these changes, priorization appears to work just fine.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the debug level is set in compilation time (by the DEBUG_LEVEL const). This method has the advantage of compiling only the relevant messages, while optimizing out the unused ones. In order to allow runtime control over the debug_level, while optimizing out messages when debug messages are not needed, we combine some methods: 1. use dynamic_debug (pr_debug) rather then printk. 2. add debug_level module param in order to set debug level during insmod. 3. add debug_level sysfs file in order to allow dynamic control over the debug level. Since patches for pr_debug_hex_dump() implementation haven't been applied yet, we are still temporarly using print_hex_dump().

To generate RX traffic: modprobe wl1271_sdio_test rx=1 To generate TX traffic: modprobe wl1271_sdio_test tx=1 To generate both RX & TX traffic, set both rx and tx to 1.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Disabling the 11a channels when not supported in the reg_notify function was not working as it should, because when the driver is initiailizing (and registering itself with mac80211), it would get the reg notification too early. At that point the driver wouldn't have received the NVS yet, so it wouldn't know whether 11a was supported. To fix this, we disable 11a channels when we read the NVS instead. Also, it is easier (and still safe) to set n_channels to zero instead of setting the disabled flag on every 11a channel. Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com>

| * wl1271: Fix setting of the hardware connection monitoring probe-req templateJuuso Oikarinen2010-11-265-13/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The probe-request template used in the hardware connection monitoring feature thus far has been an empty one, without the SSID IE and without supported rate IEs. This causes problems with some AP's. Additionally, after connected scans, the template for connection maintenance would remain to be the one last used for scanning - potentially incorrect. Fix these by getting a pre-filled directed probe-request template for the associated-to AP from mac80211.

| | | | | | | | | | | | | | | | | | | | | | | | | | Instead of simply not scanning for the 11a channels when not supported by the hardware, disable the channels in reg_notify. This centralizes the decision on whether to scan 5GHz channel in one place and allows userspace to know exactly which channels are in use. Based on Juuso Oikarinen's idea.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible that the op_remove_interface function is invoked exactly at the same time has hw recovery is started. In this case it is possible for the interface to be already removed in the op_remove_interface call, which currently leads to a kernel warning and a subsequent kernel crash. Fix this by ignoring the op_remove_interface call if the interface is already down at that point.
