Subject: [PATCH v2 bpf-next 0/4] Build BPF selftests and its libbpf, bpftool in debug mode
Date: Sat, 13 Mar 2021 13:09:16 -0800 [thread overview]
Message-ID: <20210313210920.1959628-1-andrii@kernel.org> (raw)
Build BPF selftests and libbpf and bpftool, that are used as part of
selftests, in debug mode (specifically, -Og). This makes it much simpler and
nicer to do development and/or bug fixing. See patch #4 for some unscientific
measurements.
This patch set fixes new maybe-unitialized warnings produced in -Og build
mode. Patch #1 fixes the blocker which was causing some XDP selftests failures
due to non-zero padding in bpf_xdp_set_link_opts, which only happened in debug
mode.
Andrii Nakryiko (4):
libbpf: add explicit padding to bpf_xdp_set_link_opts
bpftool: fix maybe-uninitialized warnings
selftests/bpf: fix maybe-uninitialized warning in xdpxceiver test
selftests/bpf: build everything in debug mode
