Daniel Borkmann says: ==================== pull-request: bpf-next 2019-03-04 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add AF_XDP support to libbpf. Rationale is to facilitate writing AF_XDP applications by offering higher-level APIs that hide many of the details of the AF_XDP uapi. Sample programs are converted over to this new interface as well, from Magnus. 2) Introduce a new cant_sleep() macro for annotation of functions that cannot sleep and use it in BPF_PROG_RUN() to assert that BPF programs run under preemption disabled context, from Peter. 3) Introduce per BPF prog stats in order to monitor the usage of BPF; this is controlled by kernel.bpf_stats_enabled sysctl knob where monitoring tools can make use of this to efficiently determine the average cost of programs, from Alexei. 4) Split up BPF selftest's test_progs similarly as we already did with test_verifier. This allows to further reduce merge conflicts in future and to get more structure into our quickly growing BPF selftest suite, from Stanislav. 5) Fix a bug in BTF's dedup algorithm which can cause an infinite loop in some circumstances; also various BPF doc fixes and improvements, from Andrii. 6) Various BPF sample cleanups and migration to libbpf in order to further isolate the old sample loader code (so we can get rid of it at some point), from Jakub. 7) Add a new BPF helper for BPF cgroup skb progs that allows to set ECN CE code point and a Host Bandwidth Manager (HBM) sample program for limiting the bandwidth used by v2 cgroups, from Lawrence. 8) Enable write access to skb->queue_mapping from tc BPF egress programs in order to let BPF pick TX queue, from Jesper. 9) Fix a bug in BPF spinlock handling for map-in-map which did not propagate spin_lock_off to the meta map, from Yonghong. 10) Fix a bug in the new per-CPU BPF prog counters to properly initialize stats for each CPU, from Eric. 11) Add various BPF helper prototypes to selftest's bpf_helpers.h, from Willem. 12) Fix various BPF samples bugs in XDP and tracing progs, from Toke, Daniel and Yonghong. 13) Silence preemption splat in test_bpf after BPF_PROG_RUN() enforces it now everywhere, from Anders. 14) Fix a signedness bug in libbpf's btf_dedup_ref_type() to get error handling working, from Dan. 15) Fix bpftool documentation and auto-completion with regards to stream_{verdict,parser} attach types, from Alban. ==================== Signed-off-by: David S.
