2017-03-09qed: Fix copy of uninitialized memoryrobert.foss@collabora.com
In qed_ll2_start_ooo() the ll2_info variable is uninitialized and then passed to qed_ll2_acquire_connection() where it is copied into a new memory space. This shouldn't cause any issue as long as non of the copied memory is every read. But the potential for a bug being introduced by reading this memory is real.

2017-03-09net: thunderx: Fix invalid mac addresses for node1 interfacesSunil Goutham
When booted with ACPI, random mac addresses are being assigned to node1 interfaces due to mismatch of bgx_id in BGX driver and ACPI tables. This patch fixes this issue by setting maximum BGX devices per node based on platform/soc instead of a macro. This change will set the bgx_id appropriately.

2017-03-09net: thunderx: Fix IOMMU translation faultsSunil Goutham
ACPI support has been added to ARM IOMMU driver in 4.10 kernel and that has resulted in VNIC interfaces throwing translation faults when kernel is booted with ACPI as driver was not using DMA API. This patch fixes the issue by using DMA API which inturn will create translation tables when IOMMU is enabled. Also VNIC doesn't have a seperate receive buffer ring per receive queue, so there is no 1:1 descriptor index matching between CQE_RX and the index in buffer ring from where a buffer has been used for DMA'ing. Unlike other NICs, here it's not possible to maintain dma address to virt address mappings within the driver. This leaves us no other choice but to use IOMMU's IOVA address conversion API to get buffer's virtual address which can be given to network stack for processing.

2017-03-09liquidio: improve UDP TX performanceVSR Burru
Improve UDP TX performance by: * reducing the ring size from 2K to 512 * replacing the numerous streaming DMA allocations for info buffers and gather lists with one large consistent DMA allocation per ring BQL is not effective here. We reduced the ring size because there is heavy overhead with dma_map_single every so often. With iommu=on, dma_map_single in PF Tx data path was taking longer time (~700usec) for every ~250 packets. Debugged intel_iommu code, and found that PF driver is utilizing too many static IO virtual address mapping entries (for gather list entries and info buffers): about 100K entries for two PF's each using 8 rings. Also, finding an empty entry (in rbtree of device domain's iova mapping in kernel) during Tx path becomes a bottleneck every so often; the loop to find the empty entry goes through over 40K iterations; this is too costly and was the major overhead. Overhead is low when this loop quits quickly.

The downside is that the ethernet option can be hidden. Alternatively we could make MLX5_CORE depend on "IPV6 || !IPV6", which would force MLX5_CORE to be a module when IPV6 is, including in configurations where we don't use the ethernet support at all.

2017-03-02ixgbe: Limit use of 2K buffers on architectures with 256B or larger cache linesAlexander Duyck
On architectures that have a cache line size larger than 64 Bytes we start running into issues where the amount of headroom for the frame starts shrinking. The size of skb_shared_info on a system with a 64B L1 cache line size is 320. This increases to 384 with a 128B cache line, and 512 with a 256B cache line. In addition the NET_SKB_PAD value increases as well consistent with the cache line size. As a result when we get to a 256B cache line as seen on the s390 we end up 768 bytes used by padding and shared info leaving us with only 1280 bytes to use for data storage. On architectures such as this we should default to using 3K Rx buffers out of a 8K page instead of trying to do 1.5K buffers out of a 4K page. To take all of this into account I have added one small check so that we compare the max_frame to the amount of actual data we can store. This was already occurring for igb, but I had overlooked it for ixgbe as it doesn't have strict limits for 82599 once we enable jumbo frames. By adding this check we will automatically enable 3K Rx buffers as soon as the maximum frame size we can handle drops below the standard Ethernet MTU. I also went through and fixed one small typo that I found where I had left an IGB in a variable name due to a copy/paste error.

2017-03-02ixgbe: update the rss key on h/w, when ethtool ask for itPaolo Abeni
Currently ixgbe_set_rxfh() updates the rss_key copy in the driver memory, but does not push the new value into the h/w. This commit add a new helper for the latter operation and call it in ixgbe_set_rxfh(), so that the h/w rss key value can be really updated via ethtool.

2017-03-02drivers: net: ethernet: remove incorrect __exit markupsDmitry Torokhov
Even if bus is not hot-pluggable, devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes.

2017-03-02amd-xgbe: Stop the PHY before releasing interruptsLendacky, Thomas
Some configurations require the use of the hardware's MDIO support to communicate with external PHYs. The MDIO commands indicate completion through the device interrupt. When bringing down the device the interrupts were released before stopping the external PHY, resulting in MDIO command timeouts. Move the stopping of the PHY to before the releasing of the interrupts. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>

When the structure of the LPM tree changes (f.e., due to the addition of a new prefix), we unbind the old tree and then bind the new one. This may result in temporary packet loss.

2017-02-27lib/vsprintf.c: remove %Z supportAlexey Dobriyan
Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.
