From 53a3b39da1241ba43f63f1515f6ef5167b182cae Mon Sep 17 00:00:00 2001 From: Nick Mathewson Date: Thu, 2 Jun 2016 09:46:12 -0400 Subject: Add -Wmissing-variable-declarations, with attendant fixes This is a big-ish patch, but it's very straightforward. Under this clang warning, we're not actually allowed to have a global variable without a previous extern declaration for it. The cases where we violated this rule fall into three roughly equal groups: * Stuff that should have been static. * Stuff that was global but where the extern was local to some other C file. * Stuff that was only global when built for the unit tests, that needed a conditional extern in the headers. The first two were IMO genuine problems; the last is a wart of how we build tests. --- src/or/onion_ntor.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/or/onion_ntor.c') diff --git a/src/or/onion_ntor.c b/src/or/onion_ntor.c index 9f97a4cfbe..33afc27895 100644 --- a/src/or/onion_ntor.c +++ b/src/or/onion_ntor.c @@ -47,7 +47,7 @@ typedef struct tweakset_t { } tweakset_t; /** The tweaks to be used with our handshake. */ -const tweakset_t proto1_tweaks = { +static const tweakset_t proto1_tweaks = { #define PROTOID "ntor-curve25519-sha256-1" #define PROTOID_LEN 24 PROTOID ":mac", -- cgit v1.2.3-54-g00ecf
