From 58b930ae216bfa98cd60212b954b07b9963d6d04 Mon Sep 17 00:00:00 2001 From: Siddhesh Poyarekar Date: Wed, 10 Sep 2014 21:51:50 +0530 Subject: [PATCH] Return failure in getnetgrent only when all netgroups have been searched (#17363) The netgroups lookup code fails when one of the groups in the search tree is empty. In such a case it only returns the leaves of the tree after the blank netgroup. This is because the line parser returns a NOTFOUND status when the netgroup exists but is empty. The __getnetgrent_internal implementation needs to be fixed to try remaining groups if the current group is entry. This patch implements this fix. Tested on x86_64.
