2015-08-29geneve: Use GRO cells infrastructure.Jesse Gross1-1/+16
Geneve can benefit from GRO at the device level in a manner similar to other tunnels, especially as hardware offloads are still emerging. After this patch, aggregated frames are seen on the tunnel interface. Single stream throughput nearly doubles in ideal circumstances (on old hardware).

2015-08-29vxlan: do not receive IPv4 packets on IPv6 socketJiri Benc1-0/+1
By default (subject to the sysctl settings), IPv6 sockets listen also for IPv4 traffic. Vxlan is not prepared for that and expects IPv6 header in packets received through an IPv6 socket. In addition, it's currently not possible to have both IPv4 and IPv6 vxlan tunnel on the same port (unless bindv6only sysctl is enabled), as it's not possible to create and bind both IPv4 and IPv6 vxlan interfaces and there's no way to specify both IPv4 and IPv6 remote/group IP addresses. Set IPV6_V6ONLY on vxlan sockets to fix both of these issues. This is not done globally in udp_tunnel, as l2tp and tipc seems to work okay when receiving IPv4 packets on IPv6 socket and people may rely on this behavior. The other tunnels (geneve and fou) do not support IPv6. Signed-off-by: Jiri Benc <jbenc@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-29ip_tunnels: record IP version in tunnel infoJiri Benc2-0/+4
There's currently nothing preventing directing packets with IPv6 encapsulation data to IPv4 tunnels (and vice versa). If this happens, IPv6 addresses are incorrectly interpreted as IPv4 ones. Track whether the given ip_tunnel_key contains IPv4 or IPv6 data. Store this in ip_tunnel_info. Reject packets at appropriate places if they are supposed to be encapsulated into an incompatible protocol.

2015-08-28sfc: Allow driver to cope with a lower number of VIs than it needs for RSSShradha Shah6-28/+72
Previously, the driver would refuse to load if it couldn't secure enough VIs from the MC to fulfill its RSS requirements. This was causing probe to fail on later functions in configurations where we'd run out of VIs, such as having many VFs. This change allows the driver to load with fewer VIs, down to a minimum of 2. A warning will be printed saying that RSS requirements were not met, possibly affecting performance. efx->max_tx_channels needs to be set to avoid going down the failure path in efx_probe_nic() immediately in the loop after the probe() NIC-type function. Also, Set rc=ENOSPC when bombing out of efx_probe_nic due to lack of VIs. Signed-off-by: Shradha Shah <sshah@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

A platform device can be used to provide some specific resources in order to manage the controller. In this first patch we retrieve the reset gpio which is used to power on/off the controller. The main issue is to match the current tty with the correct pdev. In case of ACPI, we can easily find the right tty/pdev pair because they are both child of the same UART port. If controller is powered-on from the driver, we need to wait for a HCI boot event before being able to send any command.

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull nvdimm fixlet from Dan Williams: "This is a libnvdimm ABI fixup. I pushed back on this change quite hard given the late date, that it appears to be purely cosmetic, sysfs is not necessarily meant to be a user friendly UI, and the kernel interprets the reversed polarity of the ACPI_NFIT_MEM_ARMED flag correctly. When this flag is set, the energy source of an NVDIMM is not armed and any new writes to the DIMM may not be preserved. However, Bob Moore warned me that it is important to get these things named correctly wherever they appear otherwise we run the risk of a less than cautious firmware engineer implementing the polarity the wrong way. Once a mistake like that escapes into production platforms the flag becomes useless and we need to move to a new bit position. Bob has agreed to take a change through ACPICA to rename ACPI_NFIT_MEM_ARMED to ACPI_NFIT_MEM_NOT_ARMED, and the patch below from Toshi brings the sysfs representation of these flags in line with their respective polarities. Please pull for 4.2 as this is the first kernel to expose the ACPI NFIT sysfs representation, and this is likely a kernel that firmware developers will be using for checking out their NVDIMM enabling" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: nfit: Clarify memory device state flags strings

2015-08-27mlxsw: Make mailboxes 4KB alignedIdo Schimmel1-33/+50
The HW-SW contract requires mailboxes passed to the firmware to be 4KB aligned. Previously, these mailboxes were mapped using streaming DMA routines, which do not guarantee the bus addresses to be 4KB aligned. Under certain conditions this constraint was indeed violated and errors were observed. By using consistent DMA mapping routines together with a mailbox size of 4KB we are guaranteed not to violate the constraint.

Commit 62ee783bf1f8 ("smsc911x: Fix crash seen if neither ACPI nor OF is configured or used") introduces an error check for the return value from device_get_phy_mode() and bails out if there is an error. Unfortunately, there are configurations where no phy is configured. Those configurations now fail. To fix the problem, accept error returns from device_get_phy_mode(), and use the return value from device_property_read_u32() to determine if there is a suitable firmware interface to read the configuration.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-08-26 This series contains updates to i40e and i40evf only. Anjali provides a fix for i40e where the part is not receiving multicast or VLAN tagged packets when in promiscuous mode. This can occur when a software bridge is created on top of the device. Fixed the legacy and MSI interrupt mode in the driver, which was non-existent before since we were assuming MSIX was the only mode that the driver ran in. Fixed the i40evf driver, where the wrong defines were getting used in the VF driver. Mitch fixes a sparse warning about comparing __le16 to u16 so use le16_to_cpu() to resolve the warning. Also fixed a dyslexic spelling of invalid. Shannon adds port.crc_errors to receive CRC error counter, since it is a receive counter. Catherine provides a fix to move the stopping of the service task and flow director to i40e_shutdown() instead of i40e_suspend(). Greg fixes the ethtool offline diagnostic with netqueues, which just need to be treated the same as virtual functions when someone wants to run the ethtool offline diagnostic test. Also fixed up code comments for the i40e ethtool diagnostic test function. Cleans up redundant and unneeded messages, since the kernel notifies all VXLAN capable registered drivers, so no need to log this. Neerav adds the ability to update statistics per VEB per traffic class and dump it via ethtool. Jingjing adds support for virtual channel offload to support receive polling mode in the VF driver. v2: dropped patch which added helper functions into a header, feedback from David Miller was to make the functions constant to reduce the driver footprint, so remove the patch while Anjali works on making the requested changes. ==================== Signed-off-by: David S.
