Miller" <davem@...emloft.net> Cc: netdev@...r.kernel.org Subject: [PATCH net-next] sparc: bpf_jit: add support for BPF_LD(X) | BPF_LEN instructions BPF_LD | BPF_W | BPF_LEN instruction is occasionally used by tcpdump and present in 11 tests in lib/test_bpf.c Teach sparc JIT compiler to emit it. Signed-off-by: Alexei Starovoitov <ast@...mgrid.com> --- coupled with pending net fix test_bpf still comes out clean on sparc64. compile tested only on sparc32 Though both patches touch the same file, there should be no conflicts between net and net-next. arch/sparc/net/bpf_jit_comp.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/arch/sparc/net/bpf_jit_comp.c b/arch/sparc/net/bpf_jit_comp.c index 7c06f18150ab..86bad49d6604 100644 --- a/arch/sparc/net/bpf_jit_comp.c +++ b/arch/sparc/net/bpf_jit_comp.c @@ -624,7 +624,12 @@ void bpf_jit_compile(struct bpf_prog *fp) emit_and(r_A, r_TMP, r_A); } break; - + case BPF_LD | BPF_W | BPF_LEN: + emit_skb_load32(len, r_A); + break; + case BPF_LDX | BPF_W | BPF_LEN: + emit_skb_load32(len, r_X); + break; case BPF_LD | BPF_IMM: emit_loadimm(K, r_A); break; -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
