2015-05-23ALSA: firewire-lib: add buffer-over-run protection at receiving more data ↵Takashi Sakamoto
blocks than expected In IEC 61883-6, the number of data blocks in a packet is limited up to the value of SYT_INTERVAL. Current implementation is compliant to the limitation, while it can cause buffer-over-run when the value of dbs field in received packet is illegally large. This commit adds a validator to detect such illegal packets to prevent the buffer-over-run. Actually, the buffer is aligned to the size of memory page, thus this issue hardly causes system errors due to the room to page alignment, as long as a few packets includes such jumbo payload; i.e. a packet to several received packets. Here, Behringer F-Control Audio 202 (based on OXFW 960) has a quirk to postpone transferring isochronous packet till finish handling any asynchronous packets. In this case, this model is lazy, transfers no packets according to several cycle-start packets. After finishing, this model pushes required data in next isochronous packet. As a result, the packet include more data blocks than IEC 61883-6 defines. To continue to support this model, this commit adds a new flag to extend the length of calculated payload. This flag allows the size of payload 5 times as large as IEC 61883-6 defines. As a result, packets from this model passed the validator successfully.

2015-05-22net: core: 'ethtool' issue with querying phy settingsArun Parameswaran
When trying to configure the settings for PHY1, using commands like 'ethtool -s eth0 phyad 1 speed 100', the 'ethtool' seems to modify other settings apart from the speed of the PHY1, in the above case. The ethtool seems to query the settings for PHY0, and use this as the base to apply the new settings to the PHY1. This is causing the other settings of the PHY 1 to be wrongly configured. The issue is caused by the '_ethtool_get_settings()' API, which gets called because of the 'ETHTOOL_GSET' command, is clearing the 'cmd' pointer (of type 'struct ethtool_cmd') by calling memset. This clears all the parameters (if any) passed for the 'ETHTOOL_GSET' cmd. So the driver's callback is always invoked with 'cmd->phy_address' as '0'. The '_ethtool_get_settings()' is called from other files in the 'net/core'. So the fix is applied to the 'ethtool_get_settings()' which is only called in the context of the 'ethtool'.

2015-05-22bridge: fix parsing of MLDv2 reportsThadeu Lima de Souza Cascardo
When more than a multicast address is present in a MLDv2 report, all but the first address is ignored, because the code breaks out of the loop if there has not been an error adding that address. This has caused failures when two guests connected through the bridge tried to communicate using IPv6. Neighbor discoveries would not be transmitted to the other guest when both used a link-local address and a static address. This only happens when there is a MLDv2 querier in the network. The fix will only break out of the loop when there is a failure adding a multicast address.

2015-05-22ipv4: Avoid crashing in ip_errorEric W. Biederman
ip_error does not check if in_dev is NULL before dereferencing it. IThe following sequence of calls is possible: CPU A CPU B ip_rcv_finish ip_route_input_noref() ip_route_input_slow() inetdev_destroy() dst_input() With the result that a network device can be destroyed while processing an input packet. A crash was triggered with only unicast packets in flight, and forwarding enabled on the only network device. The error condition was created by the removal of the network device. As such it is likely the that error code was -EHOSTUNREACH, and the action taken by ip_error (if in_dev had been accessible) would have been to not increment any counters and to have tried and likely failed to send an icmp error as the network device is going away. Therefore handle this weird case by just dropping the packet if !in_dev. It will result in dropping the packet sooner, and will not result in an actual change of behavior.

2015-05-22tcp: fix a potential deadlock in tcp_get_info()Eric Dumazet
Taking socket spinlock in tcp_get_info() can deadlock, as inet_diag_dump_icsk() holds the &hashinfo->ehash_locks[i], while packet processing can use the reverse locking order. We could avoid this locking for TCP_LISTEN states, but lockdep would certainly get confused as all TCP sockets share same lockdep classes.

2015-05-22dmaengine: rcar-dmac: fixup spinlock in rcar-dmacKuninori Morimoto
Current rcar-dmac driver is using spin_lock_irq() / spin_unlock_irq() in some functions. But, some other driver might call DMAEngine API during interrupt disabled. In such case, rcar-dmac side spin_unlock_irq() forcefully allows all interrupts. Therefore, other driver receives unexpected interruption, and its exclusive access control will be broken. This patch replaces spin_lock_irq() to spin_lock_irqsave(), and spin_unlock_irq() to spin_unlock_irqrestore().

Current DPCM is caring only FE format. but it will be no sound if FE/BE was below style, and user selects S24_LE format. FE: S16_LE/S24_LE BE: S16_LE DPCM can rewrite the format, so basically we don't want to constrain with the BE constraints. But sometimes it will be trouble. This patch adds new .dpcm_merged_format on struct snd_soc_dai_link. DPCM will use FE / BE merged format if .struct snd_soc_dai_link has it.

2015-05-22dmaengine: pl330: Fix hang on dmaengine_terminate_all on certain boardsKrzysztof Kozlowski
The pl330 device could hang infinitely on certain boards when DMA channels are terminated. It was caused by lack of runtime resume when executing pl330_terminate_all() which calls the _stop() function. _stop() accesses device register and can loop infinitely while checking for device state. The hang was confirmed by Dinh Nguyen on Altera SOCFPGA Cyclone V board during boot. It can be also triggered with: $ echo 1 > /sys/module/dmatest/parameters/iterations $ echo dma1chan0 > /sys/module/dmatest/parameters/channel $ echo 1 > /sys/module/dmatest/parameters/run $ sleep 1 $ cat /sys/module/dmatest/parameters/run Reported-by: Dinh Nguyen <dinguyen@opensource.altera.com> Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Fixes: ae43b3289186 ("ARM: 8202/1: dmaengine: pl330: Add runtime Power Management support v12") Cc: <stable@vger.kernel.org> Tested-by: Dinh Nguyen <dinguyen@opensource.altera.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
