Subject: [PATCH net-next 0/6] BPF helper improvements
Date: Tue, 28 Jun 2016 12:18:22 +0200 [thread overview]
Message-ID: <cover.1467106474.git.daniel@iogearbox.net> (raw)
This set adds various BPF helper improvements, that is, cleaning
up and adding BPF_F_CURRENT_CPU flag for tracing helper, allowing
for preemption checks on bpf_get_smp_processor_id() helper, and
adding two new helpers bpf_skb_change_{proto, type} for tc related
programs. For further details please see individual patches.
Note, this set requires -net to be merged into -net-next tree first.
Thanks a lot!
Daniel Borkmann (6):
bpf: minor cleanups on fd maps and helpers
bpf, trace: fetch current cpu only once
bpf, trace: add BPF_F_CURRENT_CPU flag for bpf_perf_event_read
bpf: don't use raw processor id in generic helper
bpf: add bpf_skb_change_proto helper
bpf: add bpf_skb_change_type helper
