ff_epoll_ctl() returns EINVAL error #617

Open shinikpark opened 3 years ago

I have no problem for setting up dpdk and compiling f-stack, neither. However, when I try to run example epoll source code, ff_epoll_ctl() function returns EINVAL error. My server OS: Ubuntu 18.04 / Kernel: Linux 5.11.

In the main() function of example/main_epoll.c:

int main(int argc, char * argv[])
{
    ff_init(argc, argv);

    sockfd = ff_socket(AF_INET, SOCK_STREAM, 0);
    printf("sockfd:%d\n", sockfd);
    if (sockfd < 0) {
        printf("ff_socket failed\n");
        exit(1);
    }

    int on = 1;
    ff_ioctl(sockfd, FIONBIO, &on);

    struct sockaddr_in my_addr;
    bzero(&my_addr, sizeof(my_addr));
    my_addr.sin_family = AF_INET;
    my_addr.sin_port = htons(80);
    my_addr.sin_addr.s_addr = htonl(INADDR_ANY);

    int ret = ff_bind(sockfd, (struct linux_sockaddr *)&my_addr, sizeof(my_addr));
    if (ret < 0) {
        printf("ff_bind failed\n");
        exit(1);
    }

    ret = ff_listen(sockfd, MAX_EVENTS);
    if (ret < 0) {
        printf("ff_listen failed\n");
        exit(1);
    }

    assert((epfd = ff_epoll_create(0)) > 0);
    ev.data.fd = sockfd;
    ev.events = EPOLLIN;

    if( ff_epoll_ctl(epfd, EPOLL_CTL_ADD, sockfd, &ev) != 0 ){
        printf("ff_epoll_ctl failed:%d, %s\n", errno,
                strerror(errno));
    }

    ff_run(loop, NULL);
    return 0;
}

When I runs the example/main_epoll.c, the output is described like this.

Can you post the build output also? It may be helpful to see the build flags used for building the example application.
