* rc80211_pid: Fix fast_start parameter handlingMattias Nissler2008-07-09
| | | | | | | | | | | | | This removes the fast_start parameter from the rc_pid parameters information and instead uses the parameter macro when initializing the rc_pid state. Since the parameter is only used on initialization, there is no point of making exporting it via debugfs. This also fixes uninitialized memory references to the fast_start and norm_offset parameters detected by the kmemcheck utility. Thanks to Vegard Nossum for reporting the bug.

* mac80211: Only flush workqueue when last interface was removedIvo van Doorn2008-07-07
| | | | | | | | | | | | | | | | Currently the ieee80211_hw->workqueue is flushed each time an interface is being removed. However most scheduled work is not interface specific but device specific, for example things like periodic work for link tuners. This patch will move the flush_workqueue() call to directly behind the call to ops->stop() to make sure the workqueue is only flushed when all interfaces are gone and there really shouldn't be any scheduled work in the drivers left.

* Revert "mac80211: Use skb_header_cloned() on TX path."David S. Miller2008-06-18
| | | | | | | | | | | | | | | | | | | | This reverts commit 608961a5eca8d3c6bd07172febc27b5559408c5d. The problem is that the mac80211 stack not only needs to be able to muck with the link-level headers, it also might need to mangle all of the packet data if doing sw wireless encryption. This fixes kernel bugzilla #10903. Thanks to Didier Raboud (for the bugzilla report), Andrew Prince (for bisecting), Johannes Berg (for bringing this bisection analysis to my attention), and Ilpo (for trying to analyze this purely from the TCP side). In 2.6.27 we can take another stab at this, by using something like skb_cow_data() when the TX path of mac80211 ends up with a non-NULL tx->key. The ESP protocol code in the IPSEC stack can be used as a model for implementation. Signed-off-by: David S. Miller <davem@davemloft.net>

* mac80211: fix alignment issue with compare_ether_addr()Senthil Balasubramanian2008-05-28
| | | | | | | | | | | | | | | This addresses an alignment issue with compare_ether_addr(). The addresses passed to compare_ether_addr should be two bytes aligned. It may function properly in x86 platform. However may not work properly on IA-64 or ARM processor. This also fixes a typo in mlme.c where the sk_buff struct name is incorect.

* mac80211: Fix for NULL pointer dereference in sta_info_get()Senthil Balasubramanian2008-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | This addresses a NULL pointer dereference in sta_info_get(). TID and sta_info are extracted in ADDBA Timer expiry function through the timer handler's argument. The problem is extracging the TID (which was stored in timer_to_tid[] array of type "u8") through "int *" typecast which may also yield unwanted bytes for the MSB of TID that results in incorrect sta_info and ieee80211_local pointers. ieee80211_local pointer is NULL as illustrated below, it crashes in sta_info_get(). The problem started when extracting ieee80211_local pointer out of sta_info iteself and eventually crashed in stat_info_get(). The proper way to fix is to change the data type of TID to u8 instead of u16. However changing all the occurences requires some prototype changes as well. We should fix this in upcoming patches.
