Subject: [PATCH v3 bpf-next 00/10] bpf: per-cpu cgroup local storage
Date: Wed, 26 Sep 2018 12:33:16 +0100 [thread overview]
Message-ID: <20180926113326.29069-1-guro@fb.com> (raw)
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
