kernel panic occurs when we create an IBSS mode and leave it for sometime without any joiner and this is introduced by the commit ec2b774e where we don't put proper braces for 'list_for_each_entry_safe' and we pass an invalid 'sta' pointer to __sta_info_destroy EIP is at __list_add+0xe/0xa0 EAX: f3b63db4 EBX: 00000000 ECX: eab88c1c EDX: 00000000 ESI: 00000000 EDI: 00000246 EBP: f3b63d80 ESP: f3b63d58 DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 Process kworker/u:2 (pid: 198, ti=f3b62000 task=f3afbea0 task.ti=f3b62000) Stack: 00000000 00000000 f9ef9821 00000000 00000000 eab88c30 f3b63d80 c017f623 eab88bf0 eab88bf0 f3b63dd0 c066f925 00000000 00000002 00000000 f9ef9821 f3b63da0 c0180a2b eab88c1c eab88c30 00000002 f3afbea0 eab88bf4 f3b63db4 Call Trace: [<f9ef9821>] ? __ieee80211_stop_tx_ba_session+0x31/0x60 [mac80211] [<c017f623>] ? debug_mutex_add_waiter+0x23/0x60 [<c066f925>] __mutex_lock_common+0xd5/0x390 [<f9ef9821>] ? __ieee80211_stop_tx_ba_session+0x31/0x60 [mac80211] [<c0180a2b>] ? trace_hardirqs_off+0xb/0x10 [<c066fd37>] mutex_lock_nested+0x47/0x60 [<f9ef9821>] ? __ieee80211_stop_tx_ba_session+0x31/0x60 [mac80211] [<f9ef9821>] __ieee80211_stop_tx_ba_session+0x31/0x60 [mac80211] [<f9ef8989>] ieee80211_sta_tear_down_BA_sessions+0x39/0x60 [mac80211] [<f9ef1a67>] __sta_info_destroy+0x57/0x780 [mac80211] [<f9ef2223>] ieee80211_sta_expire+0x93/0xb0 [mac80211] [<f9efc8f6>] ieee80211_ibss_work+0x2d6/0x530 [mac80211] Cc: Marek Lindner <lindner_marek@yahoo.de> Signed-off-by:

when we run high bandwidth UDP traffic and we trigger a scan, the scan state machine seems to be looping in SUSPEND->RESUME->DECISION->SUSPEND and SET_CHANNEL seems to be never called as 'tx_empty' is never true while running UDP traffic. fix this by settting SET_CHANNEL state when we get into RESUME state.

Error handling code following a kmalloc should free the allocated data. The label fail_alloc already does this for rfkill. A simplified version of the semantic match that finds the problem is as follows: (http://coccinelle.lip6.fr) // <smpl> @r exists@ local idexpression x; statement S; identifier f1; position p1,p2; expression *ptr != NULL; @@ x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...x...+> } x->f1 ...> ( return \(0\|<+...x...+>\|ptr\); | return@p2 ...; ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl> Signed-off-by:

AR9003 chips read tx status from ring buffer whose max number of status descriptor is mininal compared to max number of tx buffers. On a stress condition, it can be easily overflown which might cause false tx hung detection. Though increasing number of max status descriptors consumes more memory, it helps to avoid false positive chip resets. Cc: Paul Stewart <pstew@google.com> Signed-off-by:

This patch addresses a bug in the dma worker code that keeps draining packets even when the hardware queues are full. In such cases packets can not be passed down to the device and are erroneusly dropped by the code. It is based on commit bad69194, which fixes the same problem in b43. Signed-off-by:

Following the tradition we have had with ath5k, ath9k, CRDA, wireless-regdb I'd like to license this code under the permissive ISC license for the code sharing purposes with other OSes, it'd sure be nice to help the landscape in this area. Although I am %82.89 owner of the regulatory code I have asked every contributor to the regulatory code and have receieved positive Acked-bys from everyone except two deceased entities: o Frans Pop RIP 2010 [0] - Frans Pop <elendil@planet.nl> - Frans Pop <fjp@debian.org> o Nokia RIP February, 11, 2011 [1], [2] - ext-yuri.ershov@nokia.com - kalle.valo@nokia.com Frans Pop's contribution was a simple patch 55f98938, titled, "wireless: remove trailing space in messages" which just add a \n to some printk lines. I'm going to treat these additions as uncopyrightable. As for the contributions made by employees on behalf of Nokia my contact point was Petri Karhula <petri.karhula@nokia.com> but after one month he noted he had not been able to get traction from the legal department on this request, as such it I proceeded by replacing their contributions in previous patches. The end goal is to help a clean rewrite that starts in userspace that is shared under ISC license which currently is taking place with the regulatory simulator [3].
