This patchset implements per-cpu cgroup local storage and provides an example how per-cpu and shared cgroup local storage can be used for efficient accounting of network traffic.
v3->v2: 1) incorporated Song's feedback 2) rebased on top of current bpf-next
v2->v1: 1) added a selftest implementing network counters 2) added a missing free() in cgroup local storage selftest
Roman Gushchin (10): bpf: extend cgroup bpf core to allow multiple cgroup storage types bpf: rework cgroup storage pointer passing bpf: introduce per-cpu cgroup local storage bpf: don't allow create maps of per-cpu cgroup local storages bpf: sync include/uapi/linux/bpf.h to tools/include/uapi/linux/bpf.h bpftool: add support for PERCPU_CGROUP_STORAGE maps selftests/bpf: add verifier per-cpu cgroup storage tests selftests/bpf: extend the storage test to test per-cpu cgroup storage samples/bpf: extend test_cgrp2_attach2 test to use per-cpu cgroup storage selftests/bpf: cgroup local storage-based network counters
