From f43242886cae3daf0474134175707cbc02c05191 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Fri, 14 Aug 2015 13:11:04 +0200 Subject: nss-myhostname: use LOOPBACK_IFINDEX instead of if_nametoindex("lo") Given that we already hardocde the loopback ifindex, following the kernel's own logic, we can replace the invocation of if_nametoindex("lo") with LOOPBACK_IFINDEX. --- src/nss-myhostname/nss-myhostname.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/src/nss-myhostname/nss-myhostname.c b/src/nss-myhostname/nss-myhostname.c index ab96cb231e..69069cc75d 100644 --- a/src/nss-myhostname/nss-myhostname.c +++ b/src/nss-myhostname/nss-myhostname.c @@ -39,7 +39,6 @@ #define LOCALADDRESS_IPV4 (htonl(0x7F000002)) #define LOCALADDRESS_IPV6 &in6addr_loopback -#define LOOPBACK_INTERFACE "lo" NSS_GETHOSTBYNAME_PROTOTYPES(myhostname); NSS_GETHOSTBYADDR_PROTOTYPES(myhostname); @@ -117,7 +116,7 @@ enum nss_status _nss_myhostname_gethostbyname4_r( } /* If this call fails we fill in 0 as scope.
