commit b74713d0 "ath9k: Handle fatal interrupts properly" introduced a race condition, where IRQs are being left enabled, however the irq handler returns IRQ_HANDLED while the reset is still queued without addressing the IRQ cause. This leads to an IRQ storm that prevents the system from even getting to the reset code. Fix this by disabling IRQs in the handler without touching intr_ref_cnt.

There's a bug that causes the rate scaling to get stuck when it has to use single-stream rates with a peer that can do GF and SGI; the two are incompatible so we can't use them together, but that causes the algorithm to not work at all, it always rejects updates. Disable greenfield for now to prevent that problem. Cc: stable@vger.kernel.org Reviewed-by:

libertas currently calls cfg80211_disconnected() when it is being brought down. This causes an event to be allocated, but since the wdev is already removed from the rdev by the time that the event processing work executes, the event is never processed or freed. http://article.gmane.org/gmane.linux.kernel.wireless.general/95666 Fix this leak, and other possible situations, by processing the event queue when a device is being unregistered.

If the device was not found in a list of found devices names of which are pending.This may happen in a case when HCI Remote Name Request was sent as a part of incoming connection establishment procedure. Hence there is no need to continue resolving a next name as it will be done upon receiving another Remote Name Request Complete Event.

Some devices e.g. some Android based phones don't do SDP search before pairing and cancel legacy pairing when ACL is disconnected. PIN Code Request event which changes ACL timeout to HCI_PAIRING_TIMEOUT is only received after remote user entered PIN. In that case no L2CAP is connected so default HCI_DISCONN_TIMEOUT (2 seconds) is being used to timeout ACL connection. This results in problems with legacy pairing as remote user has only few seconds to enter PIN before ACL is disconnected. Increase disconnect timeout for incomming connection to HCI_PAIRING_TIMEOUT if SSP is disabled and no linkey exists. To avoid keeping ACL alive for too long after SDP search set ACL timeout back to HCI_DISCONN_TIMEOUT when L2CAP is connected. 2012-07-19 13:24:43.413521 < HCI Command: Create Connection (0x01|0x0005) plen 13 bdaddr 00:02:72:D6:6A:3F ptype 0xcc18 rswitch 0x01 clkoffset 0x0000 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 2012-07-19 13:24:43.425224 > HCI Event: Command Status (0x0f) plen 4 Create Connection (0x01|0x0005) status 0x00 ncmd 1 2012-07-19 13:24:43.885222 > HCI Event: Role Change (0x12) plen 8 status 0x00 bdaddr 00:02:72:D6:6A:3F role 0x01 Role: Slave 2012-07-19 13:24:44.054221 > HCI Event: Connect Complete (0x03) plen 11 status 0x00 handle 42 bdaddr 00:02:72:D6:6A:3F type ACL encrypt 0x00 2012-07-19 13:24:44.054313 < HCI Command: Read Remote Supported Features (0x01|0x001b) plen 2 handle 42 2012-07-19 13:24:44.055176 > HCI Event: Page Scan Repetition Mode Change (0x20) plen 7 bdaddr 00:02:72:D6:6A:3F mode 0 2012-07-19 13:24:44.056217 > HCI Event: Max Slots Change (0x1b) plen 3 handle 42 slots 5 2012-07-19 13:24:44.059218 > HCI Event: Command Status (0x0f) plen 4 Read Remote Supported Features (0x01|0x001b) status 0x00 ncmd 0 2012-07-19 13:24:44.062192 > HCI Event: Command Status (0x0f) plen 4 Unknown (0x00|0x0000) status 0x00 ncmd 1 2012-07-19 13:24:44.067219 > HCI Event: Read Remote Supported Features (0x0b) plen 11 status 0x00 handle 42 Features: 0xbf 0xfe 0xcf 0xfe 0xdb 0xff 0x7b 0x87 2012-07-19 13:24:44.067248 < HCI Command: Read Remote Extended Features (0x01|0x001c) plen 3 handle 42 page 1 2012-07-19 13:24:44.071217 > HCI Event: Command Status (0x0f) plen 4 Read Remote Extended Features (0x01|0x001c) status 0x00 ncmd 1 2012-07-19 13:24:44.076218 > HCI Event: Read Remote Extended Features (0x23) plen 13 status 0x00 handle 42 page 1 max 1 Features: 0x01 0x00 0x00 0x00 0x00 0x00 0x00 0x00 2012-07-19 13:24:44.076249 < HCI Command: Remote Name Request (0x01|0x0019) plen 10 bdaddr 00:02:72:D6:6A:3F mode 2 clkoffset 0x0000 2012-07-19 13:24:44.081218 > HCI Event: Command Status (0x0f) plen 4 Remote Name Request (0x01|0x0019) status 0x00 ncmd 1 2012-07-19 13:24:44.105214 > HCI Event: Remote Name Req Complete (0x07) plen 255 status 0x00 bdaddr 00:02:72:D6:6A:3F name 'uw000951-0' 2012-07-19 13:24:44.105284 < HCI Command: Authentication Requested (0x01|0x0011) plen 2 handle 42 2012-07-19 13:24:44.111207 > HCI Event: Command Status (0x0f) plen 4 Authentication Requested (0x01|0x0011) status 0x00 ncmd 1 2012-07-19 13:24:44.112220 > HCI Event: Link Key Request (0x17) plen 6 bdaddr 00:02:72:D6:6A:3F 2012-07-19 13:24:44.112249 < HCI Command: Link Key Request Negative Reply (0x01|0x000c) plen 6 bdaddr 00:02:72:D6:6A:3F 2012-07-19 13:24:44.115215 > HCI Event: Command Complete (0x0e) plen 10 Link Key Request Negative Reply (0x01|0x000c) ncmd 1 status 0x00 bdaddr 00:02:72:D6:6A:3F 2012-07-19 13:24:44.116215 > HCI Event: PIN Code Request (0x16) plen 6 bdaddr 00:02:72:D6:6A:3F 2012-07-19 13:24:48.099184 > HCI Event: Auth Complete (0x06) plen 3 status 0x13 handle 42 Error: Remote User Terminated Connection 2012-07-19 13:24:48.179182 > HCI Event: Disconn Complete (0x05) plen 4 status 0x00 handle 42 reason 0x13 Reason: Remote User Terminated Connection Cc: stable@vger.kernel.org Signed-off-by:Szymon Janc <szymon.janc@tieto.com> Acked-by:

AR1111 is same as AR9485. The h/w difference between them is quite insignificant, Felix suggests only very few baseband features may not be available in AR1111. The h/w code for AR9485 is already present, so AR1111 should work fine with the addition of its PID/VID. Cc: stable@vger.kernel.org [2.6.39+] Cc: Felix Bitterli <felixb@qca.qualcomm.com> Reported-by:

brcmsmac cannot call freq_reg_info() during channel changes as it does not hold cfg80211_lock, and as a result it generates a lockdep warning. freq_reg_info() is being used to determine whether OFDM is allowed on the current channel, so we can avoid the errant call by using the new IEEE80211_CHAN_NO_OFDM for this purpose instead.

On an OLPC XO-1.5 we have seen the following situation: - the system starts going into suspend - no wake params are set, so the mmc layer removes the card - during remove, we send a command to the card - that command fails, causing if_sdio's reset method to try and remove the mmc card in attempt to reset it - the mmc layer is not happy about being asked to remove a card that it is already removing, and the kernel crashes While the MMC layer could possibly be taught to behave better here, it also seems sensible for libertas not to try and reset a card if we're in the process of removing it anyway.

Currently the only way for wireless drivers to tell whether or not OFDM is allowed on the current channel is to check the regulatory information. However, this requires hodling cfg80211_mutex, which is not visible to the drivers. Other regulatory restrictions are provided as flags in the channel definition, so let's do similarly with OFDM. This patch adds a new flag, IEEE80211_CHAN_NO_OFDM, to tell drivers that OFDM on a channel is not allowed. This flag is set on any channels for which regulatory indicates that OFDM is prohibited.

Currently an skb requiring TSO may not fit within a minimum-size TX queue. The TX queue selected for the skb may stall and trigger the TX watchdog repeatedly (since the problem skb will be retried after the TX reset). This issue is designated as CVE-2012-3412. Set the maximum number of TSO segments for our devices to 100. This should make no difference to behaviour unless the actual MSS is less than about 700. Increase the minimum TX queue size accordingly to allow for 2 worst-case skbs, so that there will definitely be space to add an skb after we wake a queue. To avoid invalidating existing configurations, change efx_ethtool_set_ringparam() to fix up values that are too small rather than returning -EINVAL. Signed-off-by:

A peer (or local user) may cause TCP to use a nominal MSS of as little as 88 (actual MSS of 76 with timestamps). Given that we have a sufficiently prodigious local sender and the peer ACKs quickly enough, it is nevertheless possible to grow the window for such a connection to the point that we will try to send just under 64K at once. This results in a single skb that expands to 861 segments. In some drivers with TSO support, such an skb will require hundreds of DMA descriptors; a substantial fraction of a TX ring or even more than a full ring. The TX queue selected for the skb may stall and trigger the TX watchdog repeatedly (since the problem skb will be retried after the TX reset). This particularly affects sfc, for which the issue is designated as CVE-2012-3412. Therefore: 1. Add the field net_device::gso_max_segs holding the device-specific limit. 2. In netif_skb_features(), if the number of segments is too high then mask out GSO features to force fall back to software GSO. Signed-off-by:

Pull MIPS updates from Ralf Baechle: "The lion share of this pull request are fixes for clk-related breakage caused by other changes during this merge window. For some platforms the fix was as simple as selecting HAVE_CLK, for others like the Loongson 2 significant restructuring was required. The remainder are changes required to get the Lantiq code to work again." * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MIPS: Loongson 2: Sort out clock managment.

Pull ARM DMA engine updates from Russell King: "This looks scary at first glance, but what it is is: - a rework of the sa11x0 DMA engine driver merged during the previous cycle, to extract a common set of helper functions for DMA engine implementations. - conversion of amba-pl08x.c to use these helper functions. - addition of OMAP DMA engine driver (using these helper functions), and conversion of some of the OMAP DMA users to use DMA engine. Nothing in the helper functions is ARM specific, so I hope that other implementations can consolidate some of their code by making use of these helpers. This has been sitting in linux-next most of the merge cycle, and has been tested by several OMAP folk. I've tested it on sa11x0 platforms, and given it my best shot on my broken platforms which have the amba-pl08x controller. The last point is the addition to feature-removal-schedule.txt, which will have a merge conflict. Between myself and TI, we're planning to remove the old TI DMA implementation next year."
