Daniel Borkmann says: ==================== pull-request: bpf-next 2019-04-28 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Introduce BPF socket local storage map so that BPF programs can store private data they associate with a socket (instead of e.g. separate hash table), from Martin. 2) Add support for bpftool to dump BTF types. This is done through a new `bpftool btf dump` sub-command, from Andrii. 3) Enable BPF-based flow dissector for skb-less eth_get_headlen() calls which was currently not supported since skb was used to lookup netns, from Stanislav. 4) Add an opt-in interface for tracepoints to expose a writable context for attached BPF programs, used here for NBD sockets, from Matt. 5) BPF xadd related arm64 JIT fixes and scalability improvements, from Daniel. 6) Change the skb->protocol for bpf_skb_adjust_room() helper in order to support tunnels such as sit. Add selftests as well, from Willem. 7) Various smaller misc fixes. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
