bpf: Fix BPF_LSM kconfig symbol dependency
Similarly as 6bdacdb48e94 ("bpf: Fix BPF_JIT kconfig symbol dependency") we need to detangle the hard BPF_LSM dependency on NET. This was previously implicit by its dependency on BPF_JIT which itself was dependent on NET (but without any actual/real hard dependency code-wise). Given the latter was lifted, so should be the former as BPF_LSMs could well exist on net-less systems. This therefore also fixes a randconfig build error recently reported by Randy: ld: kernel/bpf/bpf_lsm.o: in function `bpf_lsm_func_proto': bpf_lsm.c:(.text+0x1a0): undefined reference to `bpf_sk_storage_get_proto' ld: bpf_lsm.c:(.text+0x1b8): undefined reference to `bpf_sk_storage_delete_proto' [...] Fixes: b24abcff918a ("bpf, kconfig: Add consolidated menu entry for bpf with core options") Reported-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Randy Dunlap <rdunlap@infradead.org> Tested-by: Randy Dunlap <rdunlap@infradead.org>
