Stanislav Fomichev f6d66139f8 bpf: libbpf: retry map creation without the name ... [ Upstream commit 23499442c3 ] Since commit 88cda1c9da ("bpf: libbpf: Provide basic API support to specify BPF obj name"), libbpf unconditionally sets bpf_attr->name for maps. Pre v4.14 kernels don't know about map names and return an error about unexpected non-zero data. Retry sys_bpf without a map name to cover older kernels. v2 changes: * check for errno == EINVAL as suggested by Daniel Borkmann Signed-off-by: Stanislav Fomichev <sdf@google.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Sasha Levin <sashal@kernel.org>		2019-02-12 19:47:00 +01:00
