Subject: [PATCH bpf-next 0/7] Various improvements to cgroup helpers
Date: Fri, 27 Mar 2020 16:58:49 +0100 [thread overview]
Message-ID: <cover.1585323121.git.daniel@iogearbox.net> (raw)
This adds various straight-forward helper improvements and additions to BPF
cgroup based connect(), sendmsg(), recvmsg() and bind-related hooks which
would allow to implement more fine-grained policies and improve current load
balancer limitations we're seeing. For details please see individual patches.
I've tested them on Kubernetes & Cilium and also added selftests for the small
verifier extension. Thanks!
Daniel Borkmann (7):
bpf: enable retrieval of socket cookie for bind/post-bind hook
bpf: enable perf event rb output for bpf cgroup progs
bpf: add netns cookie and enable it for bpf cgroup hooks
bpf: allow to retrieve cgroup v1 classid from v2 hooks
bpf: enable bpf cgroup hooks to retrieve cgroup v2 and ancestor id
bpf: enable retrival of pid/tgid/comm from bpf cgroup hooks
bpf: add selftest cases for ctx_or_null argument type
