问使用f-stack提供的socket的接口（ff_connect）进行连接失败，报没有权限？

代码：

ff_init(argc, argv);

int sockfd, ret, i, h;

struct sockaddr_in servaddr;

char str1[4096], str2[4096], buf[BUFSIZE], *str;

socklen_t len;

fd_set t_set1;

struct timeval tv;

//创建套接字

sockfd = ff_socket(AF_INET, SOCK_STREAM, 0);

printf("sockfd: %d\n", sockfd);

if (sockfd < 0) {

printf("创建网连接失败，本线程即将终止--socket error!\n");

exit(0);

}

bzero(&servaddr, sizeof(servaddr));

servaddr.sin_family = AF_INET;

servaddr.sin_port = htons(PORT);

if (inet_pton(AF_INET, IPSTR, &servaddr.sin_addr) <= 0) {

printf("创建网络连接失败，本线程即将终止-inet_pron error!\n");

exit(0);

}

int a = ff_connect(sockfd, (struct linux_sockaddr *)&servaddr, sizeof(servaddr));

if (a < 0) {

printf("连接到服务器失败, connect error!,err-no:%d,%d,%s \n", a, errno, strerror(errno));

exit(0);

}

运行命令：./httpget_ft --conf ../../config.ini --proc-type=primary --proc-id=0

运行报错：

如以下加粗内容，connect报错，报没有权限， 不知道什么原因（使用原生socket是没有问题的）
