Commit 45f119bf ("tcp: remove header prediction") introduced a minor bug: the sk_state_change() and sk_wake_async() notifications for a completed active connection happen twice: once in this new spot inside tcp_finish_connect() and once in the existing code in tcp_rcv_synsent_state_process() immediately after it calls tcp_finish_connect(). This commit remoes the duplicate POLL_OUT notifications. Fixes: 45f119bf ("tcp: remove header prediction") Signed-off-by:

It's been a while now since ds->dst is not an array anymore, but a simple pointer to a dsa_switch_tree. Fortunately, SF2 does not support multi-chip and thus ds->index is always 0. This patch substitutes 'ds->dst[ds->index].' with 'ds->dst->'. Signed-off-by:

Jiri Pirko says: ==================== ipv4: fib: Provide per-nexthop offload indication Ido says: Offload indication for IPv4 routes is currently set in the FIB info's flags. When multipath routes are employed, this can lead to a route being marked as offloaded although only one of its nexthops is actually offloaded. Instead, this patchset aims to proivde a higher resolution for the offload indication and report it on a per-nexthop basis. Example output from patched iproute: $ ip route show 192.168.200.0/24 192.168.200.0/24 nexthop via 192.168.100.2 dev enp3s0np7 weight 1 offload nexthop via 192.168.101.3 dev enp3s0np8 weight 1 And once the second gateway is resolved: $ ip route show 192.168.200.0/24 192.168.200.0/24 nexthop via 192.168.100.2 dev enp3s0np7 weight 1 offload nexthop via 192.168.101.3 dev enp3s0np8 weight 1 offload First patch teaches the kernel to look for the offload indication in the nexthop flags. Patches 2-5 adjust current capable drivers to provide offload indication on a per-nexthop basis. Last patch removes no longer used functions to set offload indication in the FIB info's flags. ==================== Signed-off-by: -

Now that we provide offload indication using the nexthop's flags we must refresh the offload indication whenever the offload state within the group changes. This didn't matter until now, as offload indication was provided using the FIB info flags and multipath routes were marked as offloaded as long as one of the nexthops was offloaded. Signed-off-by:

Ido Schimmel authored
Previous patch removed the reliance on the counter in the FIB info to set the offload indication, so we no longer need to keep an offload state on each FIB entry and can just set or unset the RTNH_F_OFFLOAD flag in each nexthop. This is also necessary because we're going to need to refresh the offload indication whenever the nexthop group associated with the FIB entry is refreshed. Current check would prevent us from marking a newly resolved nexthop as offloaded if the FIB entry is already marked as offloaded. Signed-off-by:

In a similar fashion to previous patch, use the nexthop flags to provide offload indication instead of the FIB info's flags. In case a nexthop in a multipath route can't be offloaded (gateway's MAC can't be resolved, for example), then its offload flag isn't set. Signed-off-by:

We want to stop using the FIB info's flags to provide the offlaod indication and instead do that on a per-nexthop basis. Convert rocker to do just that. It only supports one nexthop per-route, so conversion is simple. Signed-off-by:

We're going to have capable drivers indicate route offload using the nexthop flags, but for non-multipath routes these flags aren't dumped to user space. Instead, set the offload indication in the route message flags. Signed-off-by:

Stephen Hemminger says: ==================== netvsc: transparent VF support This patch set changes how SR-IOV Virtual Function devices are managed in the Hyper-V network driver. This version is rebased onto current net-next. Background In Hyper-V SR-IOV can be enabled (and disabled) by changing guest settings on host. When SR-IOV is enabled a matching PCI device is hot plugged and visible on guest. The VF device is an add-on to an existing netvsc device, and has the same MAC address. How is this different? The original support of VF relied on using bonding driver in active standby mode to handle the VF device. With the new netvsc VF logic, the Linux hyper-V network virtual driver will directly manage the link to SR-IOV VF device. When VF device is detected (hot plug) it is automatically made a slave device of the netvsc device. The VF device state reflects the state of the netvsc device; i.e. if netvsc is set down, then VF is set down. If netvsc is set up, then VF is brought up. Packet flow is independent of VF status; all packets are sent and received as if they were associated with the netvsc device. If VF is removed or link is down then the synthetic VMBUS path is used. What was wrong with using bonding script? A lot of work went into getting the bonding script to work on all distributions, but it was a major struggle. Linux network devices can be configured many, many ways and there is no one solution from userspace to make it all work. What is really hard is when configuration is attached to synthetic device during boot (eth0) and then the same addresses and firewall rules needs to also work later if doing bonding. The new code gets around all of this. How does VF work during initialization? Since all packets are sent and received through the logical netvsc device, initialization is much easier. Just configure the regular netvsc Ethernet device; when/if SR-IOV is enabled it just works. Provisioning and cloud init only need to worry about setting up netvsc device (eth0). If SR-IOV is enabled (even as a later step), the address and rules stay the same. What devices show up? Both netvsc and PCI devices are visible in the system. The netvsc device is active and named in usual manner (eth0). The PCI device is visible to Linux and gets renamed by udev to a persistent name (enP2p3s0). The PCI device name is now irrelevant now. The logic also sets the PCI VF device SLAVE flag on the network device so network tools can see the relationship if they are smart enough to understand how layered devices work. This is a lot like how I see Windows working. The VF device is visible in Device Manager, but is not configured. Is there any performance impact? There is no visible change in performance. The bonding and netvsc driver both have equivalent steps. Is it compatible with old bonding script? It turns out that if you use the old bonding script, then everything still works but in a sub-optimum manner. What happens is that bonding is unable to steal the VF from the netvsc device so it creates a one legged bond. Packet flow then is: bond0 <--> eth0 <- -> VF (enP2p3s0). In other words, if you get it wrong it still works, just awkward and slower. What if I add address or firewall rule onto the VF? Same problems occur with now as already occur with bonding, bridging, teaming on Linux if user incorrectly does configuration onto an underlying slave device. It will sort of work, packets will come in and out but the Linux kernel gets confused and things like ARP don’t work right. There is no way to block manipulation of the slave device, and I am sure someone will find some special use case where they want it. ==================== Signed-off-by: -

This patch implements transparent fail over from synthetic NIC to SR-IOV virtual function NIC in Hyper-V environment. It is a better alternative to using bonding as is done now. Instead, the receive and transmit fail over is done internally inside the driver. Using bonding driver has lots of issues because it depends on the script being run early enough in the boot process and with sufficient information to make the association. This patch moves all that functionality into the kernel. Signed-off-by:
