* rtlwifi: Use order 2 RX buffer allocation only if necessaryLarry Finger2011-05-26
| | | | | | | | | | Although a previous fix handles the kernel panics that result from failure to allocate a new RX buffer, memory fragmentation can be reduced if the amsdu_8k capability is disabled as new buffers need only be of O(0), not O(2).

* rtlwifi: Fix kernel panic resulting from RX buffer allocation failureLarry Finger2011-05-26
| | | | | | | | | | | | | | | | | To handle amsdu_8k capability, the PCI routine of this driver must allocate receive buffers of order 2. Under heavy load, this causes fragmentation of memory. The present code releases the current buffer before checking to see if a new one is availble. Recovery from allocation failures is not possible, which results in kernel panics. The fix is to reorder the code to check that a new buffer can be allocated before the old one is released. If not possible, the received frame is dropped and the old one is reused. Without this change, it is impossible to transfer a 2 GB file without a kernel panic.

* mwifiex: correct event header lengthYogesh Ashok Powar2011-05-26
| | | | | | | | | | | | | | | | | | | | | | | | While decoding received event packet from firmware, 4 bytes of interface header are already removed unconditionally. So for handling event only 4 more bytes needs to be pulled. This is achieved by changing event header length to 4. Almost all the events, except BA stream related and AMSDU aggregation control events, do not have the payload in their event skb. Such events handling depends only on the event ID. This event ID is the first four bytes of the event skb, which is copied to a separate variable before pulling the skb header. Hence event handling worked only for those events that didn't have payload in event skb. This patch fixes the broken event path of the events with payload in their event skb without harming existing working event path for the events without payload.

* ath9k: fix ad-hoc mode beacon selectionFelix Fietkau2011-05-19
| | | | | | | | | | | | | In ad-hoc mode, beacon timers are configured differently compared to AP mode, and (depending on the scenario) can vary enough to make the beacon tasklet not detect slot 0 based on the TSF. Since staggered beacons are not (and cannot be) used in ad-hoc mode, it makes more sense to just hardcode slot 0 here, avoiding unnecessary TSF reads and calculations.

* cfg80211: Use consistent BSS matching between scan and smeJouni Malinen2011-05-19
| | | | | | | | | | | | | | | | | cfg80211 scan code adds separate BSS entries if the same BSS shows up on multiple channels. However, sme implementation does not use the frequency when fetching the BSS entry. Fix this by adding channel information to cfg80211_roamed() and include it in cfg80211_get_bss() calls. Please note that drivers using cfg80211_roamed() need to be modified to fully implement this fix. This commit includes only minimal changes to avoid compilation issues; it maintains the old (broken) behavior for most drivers. ath6kl was the only one that I could test, so I updated it to provide the operating frequency in the roamed event.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current "huge" command handling is a bit confusing, and very limited since only one command may be huge at a time. Additionally, we often copy data around quite pointlessly since we could instead map the existing scan buffer for example and use it directly. This patch makes that possible. The first change is that multiple buffers may be given to each command (this change was prepared earlier so callsites don't need to change). Each of those can be mapped attached to a TB in the TFD, and the command header can use a TB (the first one) in the TFD as well. Doing this allows getting rid of huge commands in favour of mapping existing buffers. The beacon transmission is also optimised to not copy the SKB at all but use multiple TBs.
