bpf: Fix build failure for kernel/trace/bpf_trace.c with CONFIG_NET=n
When CONFIG_NET is not defined, I hit the following build error:
kernel/trace/bpf_trace.o:(.rodata+0x110): undefined reference to `bpf_prog_test_run_raw_tp'
Commit 1b4d60ec162f ("bpf: Enable BPF_PROG_TEST_RUN for raw_tracepoint")
added test_run support for raw_tracepoint in /kernel/trace/bpf_trace.c.
But the test_run function bpf_prog_test_run_raw_tp is defined in
net/bpf/test_run.c, only available with CONFIG_NET=y.
Adding a CONFIG_NET guard for
.test_run = bpf_prog_test_run_raw_tp;
fixed the above build issue.
Fixes: 1b4d60ec162f ("bpf: Enable BPF_PROG_TEST_RUN for raw_tracepoint")
