> Coverity found the following issues in the c code thatwe should look
> at/resolve:
> 1) zookeeper.c
> Event unterminated_case: This case (value 0) is not terminated by a 'break'
> statement.
> 717 case 0:
> 718 errno = EHOSTDOWN;
> Event fallthrough: The above case falls through to this one.
> 719 case -1:
> Event unterminated_case: This case (value 0) is not terminated by a 'break'
> statement.
> 739 case 0:
> 740 errno = EHOSTDOWN;
> Event fallthrough: The above case falls through to this one.
> 741 case -1:
> Event negative_return_fn: Called negative-returning function "socket(2, 1, 0)"
> Event var_assign: NEGATIVE return value of "socket" assigned to signed
> variable "zh->fd"
> 1099 zh->fd = socket(PF_INET, SOCK_STREAM, 0);
> Event negative_returns: Tracked variable "zh->fd" was passed to a negative
> sink.
> 1100 setsockopt(zh->fd, IPPROTO_TCP, TCP_NODELAY, &on,
> sizeof(int));
> Event deref_ptr: Directly dereferenced pointer "cptr->buffer"
> 1308 cptr->buffer->curr_offset = get_buffer_len(oa);
> Event check_after_deref: Pointer "cptr->buffer" dereferenced before NULL check
> 1309 if (!cptr->buffer) {
> cli.c
> Event returned_null: Function "strchr" returned NULL value (checked 4 out of
> 5 times)
> Event var_assigned: Variable "ptr" assigned to NULL return value from "strchr"
> 532 char *ptr = strchr(buffer, '\n');
> Event dereference: Dereferencing NULL value "ptr"
> recordio.c
> Event alloc_fn: Called allocation function "malloc"
> Event var_assign: Assigned variable "buff" to storage returned from
> "malloc(12U)"
> 284 struct buff_struct *buff = malloc(sizeof(struct buff_struct));
> Event leaked_storage: Variable "buff" goes out of scope
> At conditional (1): "!(ia != NULL)" taking true path
> 285 if (!ia) return 0;
> Event alloc_fn: Called allocation function "malloc"
> Event var_assign: Assigned variable "buff" to storage returned from
> "malloc(12U)"
> 301 struct buff_struct *buff = malloc(sizeof(struct buff_struct));
