Subject: [PATCH perf/core REBASE 0/5] Reuse libbpf from samples/bpf
Arnaldo, here's the refresh of this series that you requested after the merge
with net-next. It is based on commit 1f125a4aa4d8 ("tools lib bpf: Add flags
to bpf_create_map()") from perf/core today.
Patch #3 is new, but trivial. It has the biggest changes compared to the
version that you previously applied to perf/core.
---
Update tools/lib/bpf to provide the remaining bpf wrapper pieces needed by the
samples/bpf/ code, then get rid of all of the duplicate BPF libraries in
samples/bpf/libbpf.[ch].
---
REBASE: Rebased v3 that was applied to perf/core.
Resolved merge conflict with net-next.
New patch shifts bpf_prog_{attach,detach}() to libbpf.
Drop unnecessary build targets
Drop extra unneeded log buffers
v3: Add ack for first patch.
Split out second patch from v2 into separate changes for remaining diff.
Add patches to switch samples/bpf over to using tools/lib/.
(Was "libbpf: Synchronize implementations")
v2: Don't shift non-bpf code into libbpf.
Drop the patch to synchronize ELF definitions with tc.
v1: https://www.mail-archive.com/netdev@vger.kernel.org/msg135088.html
First post.
Joe Stringer (5):
samples/bpf: Make samples more libbpf-centric
samples/bpf: Switch over to libbpf
tools lib bpf: Add bpf_prog_{attach,detach}
samples/bpf: Remove perf_event_open() declaration
samples/bpf: Move open_raw_sock to separate header
