AF_XDP SKB mode Generic mode XDP is driver independent, used when the driver does not have support for XDP. Works on any netdevice using sockets and generic XDP path. XDP hook from netif_receive_skb(). a. nopoll - soft-irq processing b. poll - using poll() syscall Signed-off-by: Weqaar Janjua <weqaar.a.janjua@intel.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Tested-by: Yonghong Song <yhs@fb.com> Acked-by: Björn Töpel <bjorn.topel@intel.com> Link: https://lore.kernel.org/bpf/20201207215333.11586-3-weqaar.a.janjua@intel.com	2020-12-09 16:44:45 +01:00
Weqaar Janjua	a89052572e	selftests/bpf: Xsk selftests framework ... This patch adds AF_XDP selftests framework under selftests/bpf. Topology: --------- ----------- ----------- | xskX | --------- | xskY | ----------- | ----------- | | | ----------- | ---------- | vethX | --------- | vethY | ----------- peer ---------- | | | namespaceX | namespaceY Prerequisites setup by script test_xsk.sh: Set up veth interfaces as per the topology shown ^^: * setup two veth interfaces and one namespace ** veth<xxxx> in root namespace ** veth<yyyy> in af_xdp<xxxx> namespace ** namespace af_xdp<xxxx> * create a spec file veth.spec that includes this run-time configuration *** xxxx and yyyy are randomly generated 4 digit numbers used to avoid conflict with any existing interface * tests the veth and xsk layers of the topology Signed-off-by: Weqaar Janjua <weqaar.a.janjua@intel.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Tested-by: Yonghong Song <yhs@fb.com> Acked-by: Björn Töpel <bjorn.topel@intel.com> Link: https://lore.kernel.org/bpf/20201207215333.11586-2-weqaar.a.janjua@intel.com	2020-12-09 16:44:44 +01:00
