2008-12-12ath9k: Do not remove header padding on RX from short framesJouni Malinen
The 802.11 header is only padded to 32-bit boundary when the frame has a non-zero length payload. In other words, control frames (e.g., ACK) do not have a padding and we should not try to remove it. This fixes monitor mode for short control frames. In addition, the hdrlen&3 use is described in more detail to make it easier to understand how the padding length is calculated.

2008-12-12mac80211: Disable requests for new scans in AP modeJouni Malinen
AP mode operations are seriously affected if mac80211 runs through a multi-second scan while the AP is trying to send Beacon frames on the operation channel. While this could be implemented in a way that does not cause too many problems, it is not very simple and will require synchronization with Beacon frame scheduling in the drivers (scan one channel at a time between Beacon frames). Furthermore, such scanning takes quite a bit longer time and existing userspace applications would be likely to timeout while waiting for the results. For now, just refuse requests for new scans (SIOCSIWSCAN) when in AP mode. In practice, this moves the rejection from iwl* drivers into mac80211 to make it apply to every mac80211-based driver. This issue shows up in associated stations getting disconnected when something (e.g., Network Manager) requests a scan while the interface is in AP mode. When doing this continuously (e.g., NM does it every 120 seconds), the network gets close to useless.

2008-12-12ipw2200: fix scanning while associatedHelmut Schaa
This patch fixes sporadic firmware restarts when scanning while associated. The firmware will quietly cancel a scan (while associated) if the dwell time for a channel to be scanned is larger than the time it may stay away from the operating channel (because of DTIM catching). Unfortunately the driver is not notified about the canceled scan and therefore the scan watchdog timeout will be hit and the driver causes a firmware restart which results in disassociation. This mainly happens on passive channels which use a dwell time of 120 whereas a typical beacon interval is around 100. The patch changes the dwell time for passive channels to be slightly smaller than the actual beacon interval to work around the firmware issue. Furthermore the number of allowed beacon misses is increased from one to three as otherwise most scans (while associated) won't complete successfully. However scanning while associated will still fail in corner cases such as a beacon intervals below 30. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: John W.

2008-12-12rtl8187: Use usb anchor facilities to manage urbsLarry Finger
When SLUB debugging is enabled in the kernel, and the boot command includes the option "slub_debug=P", rtl8187 encounters a GPF due to a read-after-free of a urb. Following the example of changes in p54usb to fix the same problem, the code has been modified to use the usb_anchor_urb() method. With this change, the USB core handles the freeing of urb's. This patch fixes the problem reported in Kernel Bugzilla #12185 (http://bugzilla.kernel.org/show_bug.cgi?id=12185).

2008-12-12p54usb: rewriting rx/tx routines to make use of usb_anchor's facilitiesChristian Lamparter
Alan Stern found several flaws in p54usb's implementation and annotated: "usb_kill_urb() and similar routines do not expect an URB's completion routine to deallocate it.  This is almost obvious -- if the URB is deallocated before the completion routine returns then there's no way for usb_kill_urb to detect when the URB actually is complete." This patch addresses all known limitations in the old implementation and fixes khub's "use-after-freed" hang, when SLUB debug's poisoning option is enabled.

2008-12-12ath9k: BH shouldn't be enabled when hardirqs are disabled.Senthil Balasubramanian
ath_tx_complete_buf uses a BH version of spinlock and so releasing the lock enables BH which is incorrect when called from sta_notify callback as MAC80211 disables hardirqs before the driver callback is called. As ath_tx_complete_buf is shared between user and softirq context using normal spinlock may not be appropriate. Though the proper fix would be to cleanup the context properly in the driver code, this would be an interim fix to avoid kernel warning.

2008-12-12ath9k: Disable staggered Beacon frame schedulingJouni Malinen
It looks like there are some issues in the current ath9k version as far as staggered Beacon frame scheduling is concerned. This results in Beacon frame timestamp being off by 25 milliseconds or so which can cause issues with multicast power save buffering in AP mode. Some client stations fail to receive multicast frames when there is this large an offset between TBTT and actual Beacon transmission time. Since ath9k does not yet support multiple BSSes anyway, the staggered Beacon frame scheduling is just increasing the number of interrupts at this point. The easiest fix for the timestamp offset is to disable staggered Beacon frames for now. We need to redesign beacon.c anyway when adding multi-BSS support with mac80211 since the existing code depends on different mechanism for Beacon frame transmission.
