Please refer to the patch 1/6 as the main patch with the details on the current sendmsg hook API limitations and proposal to fix it in order to work with basic applications like DNS. Remaining patches are the usual uapi and tooling updates as well as test cases. Thanks a lot!
v2 -> v3: - Add attach types to test_section_names.c and libbpf (Andrey) - Added given Acks, rest as-is v1 -> v2: - Split off uapi header sync and bpftool bits (Martin, Alexei) - Added missing bpftool doc and bash completion as well Daniel Borkmann (6): bpf: fix unconnected udp hooks bpf: sync tooling uapi header bpf, libbpf: enable recvmsg attach types bpf, bpftool: enable recvmsg attach types bpf: more msg_name rewrite tests to test_sock_addr bpf: expand section tests for test_section_names include/linux/bpf-cgroup.h | 8 + include/uapi/linux/bpf.h | 2 + kernel/bpf/syscall.c | 8 + kernel/bpf/verifier.c | 12 +- net/core/filter.c | 2 + net/ipv4/udp.c | 4 + net/ipv6/udp.c | 4 + .../bpftool/Documentation/bpftool-cgroup.rst | 6 +- .../bpftool/Documentation/bpftool-prog.rst | 2 +- tools/bpf/bpftool/bash-completion/bpftool | 5 +- tools/bpf/bpftool/cgroup.c | 5 +- tools/bpf/bpftool/prog.c | 3 +- tools/include/uapi/linux/bpf.h | 2 + tools/lib/bpf/libbpf.c | 4 + .../selftests/bpf/test_section_names.c | 10 + tools/testing/selftests/bpf/test_sock_addr.c | 213 ++++++++++++++++-- 16 files changed, 264 insertions(+), 26 deletions(-) -- 2.17.1
