bpf: Add bpf_jit_blinding_enabled for !CONFIG_BPF_JIT
Add a definition of bpf_jit_blinding_enabled() when CONFIG_BPF_JIT is not set in order to fix a recent build regression: [...] CC kernel/bpf/verifier.o CC kernel/bpf/inode.o kernel/bpf/verifier.c: In function ‘fixup_bpf_calls’: kernel/bpf/verifier.c:9132:25: error: implicit declaration of function ‘bpf_jit_blinding_enabled’; did you mean ‘bpf_jit_kallsyms_enabled’? [-Werror=implicit-function-declaration] 9132 | bool expect_blinding = bpf_jit_blinding_enabled(prog); | ^~~~~~~~~~~~~~~~~~~~~~~~ | bpf_jit_kallsyms_enabled CC kernel/bpf/helpers.o CC kernel/bpf/hashtab.o [...] Fixes: d2e4c1e6c294 ("bpf: Constant map key tracking for prog array pokes") Reported-by: Jakub Sitnicki <jakub@cloudflare.com> Reported-by: Andrii Nakryiko <andriin@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Link: https://lore.kernel.org/bpf/40baf8f3507cac4851a310578edfb98ce73b5605.1574541375.git.daniel@iogearbox.net
