Add a separate test file tests/system-bpf-traffic.at for bpf testing. The test cases are a subset of the existing system-traffic.at, and with additional bpf-specific tests. When test passes, the log f

This patch adds the OVS-eBPF datapath implementation for dpif-bpf. Three stages are added: parse, lookup, and actions. Each stages are tail called to the next stage. When executing multiple actions, t

The patch initializes the bpf datapath when bridge starts. The check_support could be avoided since we know what datapath bpf program supports what feature. Signed-off-by: Joe Stringer <joe@...> Signe

From: Joe Stringer <joe@...> Add an implementation of the API between the userspace "Open vSwitch Datapath Protocol" and the BPF datapath. Signed-off-by: Joe Stringer <joe@...> Signed-off-by: William

From: Joe Stringer <joe@...> Implement a new datapath interface for use with BPF datapaths. Like dpif-netlink, dpif-bpf is backed by an implementation which resides within the kernel. It uses the BPF

From: Joe Stringer <joe@...> Through libbpf, the patch adds support for loading bpf program and maps, pinning the program and map to /sys/fs/bpf/ovs/, managing the file descriptor of each loaded map,

From: Joe Stringer <joe@...> A flow missed by the match action table in ebpf triggers an upcall, which forwards the information to ovs-vswitchd using skb_perf_event_output helper function. The patch i

From: Joe Stringer <joe@...> To receive packets, an eBPF program has to be attached to a netdev through tc ingress/egress, an XDP program has to be attached to a netdev's xdp hook point. The patch int

From: Joe Stringer <joe@...> The patch add bpf installation guide and configuration for linking to libbpf library. Co-authored-by: William Tu <u9012063@...> Co-authored-by: Yifeng Sun <pkusunyifeng@..

Today OVS has three datapath types: Linux kernel (dpif-netlink), userspace (dpif-netdev), and Windows. This series add another type of OVS datapath: the eBPF datapath (dpif-bpf). eBPF stands for exten

Hi! There is multiple options to attach a BPF program (BPF.attach_kprobe(), BPF.attach_uprobe(), etc) but currently possible to attach BPF program to socket with the BCC python frontend? In C its easy
