From 1fbd20f8b77b366ea4aeb92ade72daa7f36a7e3b Mon Sep 17 00:00:00 2001 From: Andrey Ignatov Date: Wed, 3 Apr 2019 23:22:43 -0700 Subject: bpf: Add missed newline in verifier verbose log check_stack_access() that prints verbose log is used in adjust_ptr_min_max_vals() that prints its own verbose log and now they stick together, e.g.: variable stack access var_off=(0xfffffffffffffff0; 0x4) off=-16 size=1R2 stack pointer arithmetic goes out of range, prohibited for !root Add missing newline so that log is more readable: variable stack access var_off=(0xfffffffffffffff0; 0x4) off=-16 size=1 R2 stack pointer arithmetic goes out of range, prohibited for !root Fixes: f1174f77b50c ("bpf/verifier: rework value tracking") Signed-off-by: Andrey Ignatov Signed-off-by: Daniel Borkmann --- kernel/bpf/verifier.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'kernel/bpf') diff --git a/kernel/bpf/verifier.c b/kernel/bpf/verifier.c index f2d600199e66..48718e1da16d 100644 --- a/kernel/bpf/verifier.c +++ b/kernel/bpf/verifier.c @@ -1426,7 +1426,7 @@ static int check_stack_access(struct bpf_verifier_env *env, char tn_buf[48]; tnum_strn(tn_buf, sizeof(tn_buf), reg->var_off); - verbose(env, "variable stack access var_off=%s off=%d size=%d", + verbose(env, "variable stack access var_off=%s off=%d size=%d\n", tn_buf, off, size); return -EACCES; } -- cgit v1.2.3
