Subject: [PATCH v2 bpf-next 0/4] bpf: Enable bpf_sk_storage for FENTRY/FEXIT/RAW_TP
Date: Thu, 12 Nov 2020 13:12:55 -0800 [thread overview]
Message-ID: <20201112211255.2585961-1-kafai@fb.com> (raw)
This set is to allow the FENTRY/FEXIT/RAW_TP tracing program to use
bpf_sk_storage. The first two patches are a cleanup. The last patch is
tests. Patch 3 has the required kernel changes to
enable bpf_sk_storage for FENTRY/FEXIT/RAW_TP.
Please see individual patch for details.
v2:
- Rename some of the function prefix from sk_storage to bpf_sk_storage
- Use prefix check instead of substr check
Martin KaFai Lau (4):
bpf: Folding omem_charge() into sk_storage_charge()
bpf: Rename some functions in bpf_sk_storage
bpf: Allow using bpf_sk_storage in FENTRY/FEXIT/RAW_TP
bpf: selftest: Use bpf_sk_storage in FENTRY/FEXIT/RAW_TP
