2014-11-17ieee802154: rename and move WPAN_NUM_ definesAlexander Aring
This patch moves the 802.15.4 constraints WPAN_NUM_ defines into "net/ieee802154.h" which should contain all necessary 802.15.4 related information. Also rename these defines to a common name which is IEEE802154_MAX_CHANNEL and IEEE802154_MAX_PAGE.

2014-11-17ieee802154: setting extended address while iface addAlexander Aring
This patch adds support for setting an extended address while registration a new interface. If ieee802154_is_valid_extended_addr getting as parameter and invalid extended address then the perm address is fallback. This is useful to make some default handling while for example default registration of a wpan interface while phy registration.

2014-11-17mac802154: use new nl802154 iftype typesAlexander Aring
This patch replace the depracted IEEE802154_DEV to the new introduced NL802154_IFTYPE_NODE types. There is a backwards compatibility to have the identical types for both enum definitions. Also remove some inlcude issue with "linux/nl802154.h", because the export nl_policy inside this header it was always necessary to have an include of "net/rtnetlink.h" before. The reason for this is more complicated. Nevertheless we removed this now, because "linux/nl802154.h" is the depracted netlink interface.

2014-11-17dmaengine: Fix allocation size for PL330 data buffer depth.Liviu Dudau
The datasheet for PL330 says that the data buffer value in the CRD register is 10bits wide. However, the value stored is "minus one", which the driver corrects for. Maximum value that the data buffer depth can have is 1024 lines, which requires 11 bits for storage. While making updates I found printing the peripheral ID as a hex value to be more useful as the datasheet shows the values that way.

2014-11-17dmaengine: pl330: Align DMA memcpy operations to MFIFO widthJon Medhurst
The algorithm used for programming the DMA Controller doesn't take into consideration the requirements of transfers that are not aligned to the bus width. This failure may result in DMA transferring one too few MFIFO entries (so too few bytes are copied) or the DMA trying to write one too many MFIFO entries and hanging because this is never provided. See "MFIFO Usage Overview" chapter in the the TRM for "CoreLink DMA Controller DMA-330", Revision r1p1. We work around these shortcomings by making sure we pick a burst size and length which ensures no bursts straddle an MFIFO entry.

2014-11-17md: Always set RECOVERY_NEEDED when clearing RECOVERY_FROZENNeilBrown
md_check_recovery will skip any recovery and also clear MD_RECOVERY_NEEDED if MD_RECOVERY_FROZEN is set. So when we clear _FROZEN, we must set _NEEDED and ensure that md_check_recovery gets run. Otherwise we could miss out on something that is needed. In particular, this can make it impossible to remove a failed device from an array is the 'recovery-needed' processing didn't happen.

However, in MLD/IGMP code, we have some rather ugly AVAILABLE(skb) macros, which determine if we may end up doing an skb_put() for adding another record. To avoid possible fragmentation, we check the skb's tailroom as skb->dev->mtu - skb->len, which is a wrong assumption as the actual max allocation size can be much smaller. The IGMP case doesn't have this issue as commit 57e1ab6eaddc ("igmp: refine skb allocations") stores the allocation size in the cb[]. Set a reserved_tailroom to make it fit into the MTU and use skb_availroom() helper instead. This also allows to get rid of igmp_skb_size().

Eric Dumazet says: ==================== net: provide common RSS key infrastructure RSS (Receive Side Scaling) uses a 40 bytes key to provide hash for incoming packets to select appropriate incoming queue on NIC. Hash algo (Toeplitz) is also well known and documented by Microsoft (search for "Verifying the RSS Hash Calculation") Problem is that some drivers use a well known key. It makes very easy for attackers to target one particular RX queue, knowing that number of RX queues is a power of two, or at least some small number. Other drivers use a random value per port, making difficult tuning on bonding setups. Lets add a common infrastructure, so that host gets an unique RSS key, and drivers do not have to worry about this. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2014-11-16net: provide a per host RSS key generic infrastructureEric Dumazet
RSS (Receive Side Scaling) typically uses Toeplitz hash and a 40 or 52 bytes RSS key. Some drivers use a constant (and well known key), some drivers use a random key per port, making bonding setups hard to tune. Well known keys increase attack surface, considering that number of queues is usually a power of two. This patch provides infrastructure to help drivers doing the right thing. netdev_rss_key_fill() should be used by drivers to initialize their RSS key, even if they provide ethtool -X support to let user redefine the key later. A new /proc/sys/net/core/netdev_rss_key file can be used to get the host RSS key even for drivers not providing ethtool -x support, in case some applications want to precisely setup flows to match some RX queues. Tested: myhost:~# cat /proc/sys/net/core/netdev_rss_key 11:63:99:bb:79:fb:a5:a7:07:45:b2:20:bf:02:42:2d:08:1a:dd:19:2b:6b:23:ac:56:28:9d:70:c3:ac:e8:16:4b:b7:c1:10:53:a4:78:41:36:40:74:b6:15:ca:27:44:aa:b3:4d:72 myhost:~# ethtool -x eth0 RX flow hash indirection table for eth0 with 8 RX ring(s): 0: 0 1 2 3 4 5 6 7 RSS hash key: 11:63:99:bb:79:fb:a5:a7:07:45:b2:20:bf:02:42:2d:08:1a:dd:19:2b:6b:23:ac:56:28:9d:70:c3:ac:e8:16:4b:b7:c1:10:53:a4:78:41 Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

Additionally, support is added for reading the mv88e6171 via ethtool. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2014-11-16net: dsa: mv88e6171: Add support for reading switch registersAndrew Lunn
The infrastructure can now report switch registers to ethtool. Add support for it to the mv88e6171 driver. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-11-16net: dsa: mv88e6171: Add support for reading the temperatureAndrew Lunn
This chip also has a temperature sensor which can be read using the common code. In order to use it, add the needed mutex protection for accessing registers via the shared code. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-11-16net: dsa: Centralise code for reading the temperature sensorAndrew Lunn
The method to read the temperature used in the mve6123_61_65 driver can also be used for other chips. Move the code into the shared code base of mv88e6xxx.c. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

Set the threshold to low by default. With this thresholds any movement on the device with this sensor will generate event. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
