From 131213e675b0e07d8d47b70564428c9584addd18 Mon Sep 17 00:00:00 2001 From: Jakub Hrozek Date: Tue, 15 Jan 2013 17:31:18 +0100 Subject: LDAP: avoid complex realloc logic in save_rfc2307bis_group_memberships https://fedorahosted.org/sssd/ticket/1761 The function tried to be smart and realloc only when needed, but that only lead to hard-to find bugs where the logic would not allocate the proper space. Remove the reallocation and prefer readability over speed in this case. --- src/providers/ldap/sdap_async_initgroups.c | 16 ++++------------ 1 file changed, 4 insertions(+), 12 deletions(-) (limited to 'src/providers') diff --git a/src/providers/ldap/sdap_async_initgroups.c b/src/providers/ldap/sdap_async_initgroups.c index 66be76e66..e9d1f3cc9 100644 --- a/src/providers/ldap/sdap_async_initgroups.c +++ b/src/providers/ldap/sdap_async_initgroups.c @@ -1793,7 +1793,6 @@ save_rfc2307bis_group_memberships(struct sdap_initgr_rfc2307bis_state *state) int num_added; int i; int grp_count; - int grp_count_old = 0; char **add = NULL; tmp_ctx = talloc_new(NULL); @@ -1833,12 +1832,10 @@ save_rfc2307bis_group_memberships(struct sdap_initgr_rfc2307bis_state *state) * nesting limit.
