From 29ba9812bb86bf6da9702f4fbff5cdbb25846401 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 1 Jul 2009 02:42:59 -0700 Subject: Fix getnetbyaddr implementation. There were two problems in the getnetbyaddr implementation. The type argument is pretty much useless since (almost) no input file contains this information and the NSS backends make up the value they fill in for the n_addrtype field. Therefore we now declare that passing AF_UNSPEC is always recognized. Secondly, the files backend didn't compare the network numbers with the correct endianess. Also change getent to take advantage of the type parameter change. --- nss/getent.c | 2 +- nss/nss_files/files-network.c | 5 +++-- 2 files changed, 4 insertions(+), 3 deletions(-) (limited to 'nss') diff --git a/nss/getent.c b/nss/getent.c index 3a9430fd66..3a482e140f 100644 --- a/nss/getent.c +++ b/nss/getent.c @@ -534,7 +534,7 @@ networks_keys (int number, char *key[]) for (i = 0; i < number; ++i) { if (isdigit (key[i][0])) - net = getnetbyaddr (inet_addr (key[i]), AF_UNIX); + net = getnetbyaddr (inet_addr (key[i]), AF_UNSPEC); else net = getnetbyname (key[i]); diff --git a/nss/nss_files/files-network.c b/nss/nss_files/files-network.c index 9f4a3e0324..064de5a143 100644 --- a/nss/nss_files/files-network.c +++ b/nss/nss_files/files-network.c @@ -1,5 +1,5 @@ /* Networks file parser in nss_files module. - Copyright (C) 1996, 1997, 1998, 2000, 2001 Free Software Foundation, Inc. + Copyright (C) 1996-1998, 2000, 2001, 2009 Free Software Foundation, Inc.
