When 'datum.values' or 'datum.keys' is NULL, some code path calling
into ovsdb_idl_txn_write__ triggers NULL deref. An example is below:
ovsrec_open_vswitch_set_cur_cfg(const struct ovsrec_open_vswitch
{
struct ovsdb_datum datum;
union ovsdb_atom key;
datum.n = 1;
datum.keys =
An exmplae pattern shown below:
void
ovsrec_ct_zone_index_set_external_ids(const struct ovsrec_ct_zone...
{
// 1. alloc_fn: Storage is returned from allocation function xmalloc.
// 2. var_assign: Assigning: datum = storage returned from xmalloc(24UL).
struct ovsdb_datum *datum =
Coverity shows the following memory leak in this code pattern:
void
ovsrec_ipfix_index_set_obs_domain_id(
{
struct ovsdb_datum datum;
// 1. alloc_fn: Storage is returned from allocation function xmalloc.
// 2. var_assign: Assigning: key = storage returned from xmalloc(16UL).
union
The three patches fix around 350 memory-related defects reported
by Coverity. With this series applied, Coverity still shows
around 130 defetcs.
