Daniel Borkmann 6bdacdb48e bpf: Fix BPF_JIT kconfig symbol dependency ... Randy reported a randconfig build error recently on i386: ld: arch/x86/net/bpf_jit_comp32.o: in function `do_jit': bpf_jit_comp32.c:(.text+0x28c9): undefined reference to `__bpf_call_base' ld: arch/x86/net/bpf_jit_comp32.o: in function `bpf_int_jit_compile': bpf_jit_comp32.c:(.text+0x3694): undefined reference to `bpf_jit_blind_constants' ld: bpf_jit_comp32.c:(.text+0x3719): undefined reference to `bpf_jit_binary_free' ld: bpf_jit_comp32.c:(.text+0x3745): undefined reference to `bpf_jit_binary_alloc' ld: bpf_jit_comp32.c:(.text+0x37d3): undefined reference to `bpf_jit_prog_release_other' [...] The cause was that b24abcff91 ("bpf, kconfig: Add consolidated menu entry for bpf with core options") moved BPF_JIT from net/Kconfig into kernel/bpf/Kconfig and previously BPF_JIT was guarded by a 'if NET'. However, there is no actual dependency on NET, it's just that menuconfig NET selects BPF. And the latter in turn causes kernel/bpf/core.o to be built which contains above symbols. Randy's randconfig didn't have NET set, and BPF wasn't either, but BPF_JIT otoh was. Detangle this by making BPF_JIT depend on BPF instead. arm64 was the only arch that pulled in its JIT in net/ via obj-$(CONFIG_NET), all others unconditionally pull this dir in via obj-y. Do the same since CONFIG_NET guard there is really useless as we compiled the JIT via obj-$(CONFIG_BPF_JIT) += bpf_jit_comp.o anyway.
