Problem statement:

In file ldapserver/ldap/servers/slapd/back-ldbm/dblayer.c and function "dblayer_seek43_large" the ret is declared as a int type. ideally int can hold upto 2147483647. As ns-slapd is a 64 bit application, the ret type should have bin unsigned long type.

if 1000DB_VERSION_MAJOR + 100DB_VERSION_MINOR >= 4300

/ Helper function for large seeks, db4.3 /
static int dblayer_seek43_large(int fd, off64_t offset, int whence)
{
int ret = 0; / This is problem here, it should have been off64_t type /

ret = lseek64(fd, offset, whence);

return (ret < 0) ? errno : 0;

}

else

Fix details:

if 1000DB_VERSION_MAJOR + 100DB_VERSION_MINOR >= 4300

/ Helper function for large seeks, db4.3 /
static int dblayer_seek43_large(int fd, off64_t offset, int whence)
{
off64_t ret = 0; / Defined as unsigned long type instead of int /

ret = lseek64(fd, offset, whence);

return (ret < 0) ? errno : 0;
