netdevsim: add software driver for testing offloads

2017-12-02T23:27:57Z

To be able to run selftests without any hardware required we need a software model. The model can also serve as an example implementation for those implementing actual HW offloads. The dummy driver have previously been extended to test SR-IOV, but the general consensus seems to be against adding further features to it. Add a new driver for purposes of software modelling only. eBPF and SR-IOV will be added here shortly, others are invited to further extend the driver with their offload models.

net: Add support for networking over Thunderbolt cable

2017-10-02T18:24:42Z

ThunderboltIP is a protocol created by Apple to tunnel IP/ethernet traffic over a Thunderbolt cable. The protocol consists of configuration phase where each side sends ThunderboltIP login packets (the protocol is determined by UUID in the XDomain packet header) over the configuration channel. Once both sides get positive acknowledgment to their login packet, they configure high-speed DMA path accordingly. This DMA path is then used to transmit and receive networking traffic. This patch creates a virtual ethernet interface the host software can use in the same way as any other networking interface. Once the interface is brought up successfully network packets get tunneled over the Thunderbolt cable to the remote host and back. The connection is terminated by sending a ThunderboltIP logout packet over the configuration channel. We do this when the network interface is brought down by user or the driver is unloaded.

x86/lguest: Remove lguest support

2017-08-24T07:57:28Z

Lguest seems to be rather unused these days. It has seen only patches ensuring it still builds the last two years and its official state is "Odd Fixes". Remove it in order to be able to clean up the paravirt code.

vmxnet3: prevent building with 64K pages

2017-02-17T20:25:49Z

I got a warning about broken code on ARM64 with 64K pages: drivers/net/vmxnet3/vmxnet3_drv.c: In function 'vmxnet3_rq_init': drivers/net/vmxnet3/vmxnet3_drv.c:1679:29: error: large integer implicitly truncated to unsigned type [-Werror=overflow] rq->buf_info[0][i].len = PAGE_SIZE; 'len' here is a 16-bit integer, so this clearly won't work. I don't think this driver is used much on anything other than x86, so there is no need to fix this properly and we can work around it with a Kconfig dependency to forbid known-broken configurations. qemu in theory supports it on other architectures too, but presumably only for compatibility with x86 guests that also run on vmware. CONFIG_PAGE_SIZE_64KB is used on hexagon, mips, sh and tile, the other symbols are architecture-specific names for the same thing. Signed-off-by: Arnd Bergmann Signed-off-by: David S. Miller

ipvtap: IP-VLAN based tap driver

2017-02-12T01:59:41Z

This patch adds a tap character device driver that is based on the IP-VLAN network interface, called ipvtap. An ipvtap device can be created in the same way as an ipvlan device, using 'type ipvtap', and then accessed using the tap user space interface. Signed-off-by: Sainath Grandhi Signed-off-by: David S.

ipvlan: Introduce l3s mode

2016-09-19T05:25:22Z

In a typical IPvlan L3 setup where master is in default-ns and each slave is into different (slave) ns. In this setup egress packet processing for traffic originating from slave-ns will hit all NF_HOOKs in slave-ns as well as default-ns. However same is not true for ingress processing. All these NF_HOOKs are hit only in the slave-ns skipping them in the default-ns. IPvlan in L3 mode is restrictive and if admins want to deploy iptables rules in default-ns, this asymmetric data path makes it impossible to do so. This patch makes use of the l3_rcv() (added as part of l3mdev enhancements) to perform input route lookup on RX packets without changing the skb->dev and then uses nf_hook at NF_INET_LOCAL_IN to change the skb->dev just before handing over skb to L4.
