This patchset implements BPF_LWT_ENCAP_IP mode in bpf_lwt_push_encap BPF helper. It enables BPF programs (specifically, BPF_PROG_TYPE_LWT_IN and BPF_PROG_TYPE_LWT_XMIT prog types) to add IP encapsulation headers to packets (e.g. IP/GRE, GUE, IPIP). This is useful when thousands of different short-lived flows should be encapped, each with different and dynamically determined destination. Although lwtunnels can be used in some of these scenarios, the ability to dynamically generate encap headers adds more flexibility, e.g. when routing depends on the state of the host (reflected in global bpf maps).For the set: Reviewed-by: David Ahern <redacted>Applied. Thanks everyone!
Looks like a cleanup round is needed. I changed the routes to fail with unreachable:

should let all of the tests run versus bailing on the first failure).
With kmemleak enabled I see a lot of suspected memory leaks - some may
not be related to this change but it is triggering the suspected leak:
