From 1b5cdd76b76a98e464f352c1d44be3ea0b279c87 Mon Sep 17 00:00:00 2001 From: Björn Jacke Date: Tue, 7 Sep 2010 01:04:10 +0200 Subject: s3/ldap: use monotonic clock for timeouts in smbldap tevent would need monotonic clock features to make also smbldap's idle handling aware of backward clock jumps. Other areas in smbldap are clock jump save now. --- source3/lib/smbldap.c | 40 +++++++++++++++++++++++----------------- 1 file changed, 23 insertions(+), 17 deletions(-) (limited to 'source3/lib') diff --git a/source3/lib/smbldap.c b/source3/lib/smbldap.c index 996c1c4c85..67e3d4dc1b 100644 --- a/source3/lib/smbldap.c +++ b/source3/lib/smbldap.c @@ -958,6 +958,7 @@ static int rebindproc_with_state (LDAP * ld, char **whop, char **credp, int *methodp, int freeit, void *arg) { struct smbldap_state *ldap_state = arg; + struct timespec ts; /** @TODO Should we be doing something to check what servers we rebind to?
