From 1c94ea2b5c88a5b3bd28b3f34eb22260af26f324 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Vladim=C3=ADr=20=C4=8Cun=C3=A1t?= <vladimir.cunat@nic.cz> Date: Tue, 16 Apr 2019 12:52:16 +0200 Subject: [PATCH] lua net.interfaces(): fix mac addresses Only the first byte was being shown since 3ab77332. I can't see at all why this part was changed; the buffer is (and was) way overlong for this, so writing one zero byte just after the end is OK. --- daemon/bindings/net.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/daemon/bindings/net.c b/daemon/bindings/net.c index 0b22ffcb6..144f8b47f 100644 --- a/daemon/bindings/net.c +++ b/daemon/bindings/net.c @@ -240,11 +240,11 @@ static int net_interfaces(lua_State *L) /* Hardware address. */ char *p = buf; - memset(buf, 0, sizeof(buf)); - for (unsigned k = 0; k < sizeof(iface.phys_addr); ++k) { - sprintf(p, "%s%.2x", k > 0 ?
