autofs-5.0.5 - more code analysis corrections (and fix a typo in an init script)
From: Jeff Moyer <jmoyer@redhat.com>
- fix an obvious type in Redhat init script.
- don't call ldap_msgfree when result pointer is null.
- check return of ldap_parse_result as pointers will be invalid on fail.
- get rid of a bogus assignment in defaults_free_searchdns.
- get rid of unused optlen variable in parse_sun.c.
- check return status of stat(2) in do_mount_direct().
- get rid of unused name variable in master_add_map_source().
- check return from ops->askumount() in expire_cleanup().
- in mount_autofs.c:mount_mount(), don't increment val since we never
look at it again.
- in autofs_sasl_dispose() ctxt must always be valid or we would have
a much bigger problem.
- in st_start_handler() and alarm_start_handler() it is possible for
pthread_attr_destroy() to be called with a NULL pointer.
- we could end up with a non-null result pointer after a failed call to
ldap_search_s(), well maybe, so check for it anyway.
