Summary0000231: easycwmpd console exit and CPE timeout when IPPingDiagnostics
DescriptionI have rewrite the srcipt ipping_diagnostic and ipping_launch for my CPE test on the HuaWei's ITMS(ACS).I meet a probrom that easycwmpd console exit and CPE timeout when IPPingDiagnostics.
After the ACS save parameters sucess, that is, the ACS receive the SetParameterValuesResponse from the CPE.
then ,the ACS will read the result of ping Diagnostics immediately once.
Steps To Reproduce1. set parameter DiagnosticsState is Requested, and host is 192.168.20.99
2. apply and check console.
3. the console printf "User defined signal 1" and then the CPE offline.

I analyse that easycwmpd console exit and CPE timeout and offline is because that my easycwmp funcition.

int external_init()
{
    log_message(NAME, L_NOTICE, "external script init\n");
    if (pipe(pfds_out) < 0)
            return -1;
    if (pipe(pfds_in) < 0)
            return -1;
    if ((pid = fork()) == -1) {
        log_message(NAME, L_CRIT, "external init fork failed\n");
        return -1;
    }

    if (pid == 0) {
        /* child */
        close(pfds_out[0]);
        dup2(pfds_out[1], STDOUT_FILENO);
        close(pfds_out[1]);

        close(pfds_in[1]);
        dup2(pfds_in[0], STDIN_FILENO);
        close(pfds_in[0]);

        int i=0;
        const char *argv[4];
        argv[i++] = fc_script;
        argv[i++] = "--json-input";
        argv[i++] = NULL;

        execvp(argv[0], (char **) argv);
        exit(ESRCH);
    } else if (pid < 0)
        return -1;


    close(pfds_out[1]);
    close(pfds_in[0]);

    if (signal(SIGPIPE, SIG_IGN) == SIG_ERR)
        log_message(NAME, L_CRIT, "ignoring pipe signal failed\n");

    int r = external_read_pipe(NULL);
    return r;
}
The function don't the sigal SIGHUP to handle. your idea? I'm urgent to know your analysis and solution,.
thanks!

I add following code to capture the sigal SIGUSR1 in the external_init function.
......
   if (signal(SIGUSR1, SIG_IGN) == SIG_ERR)
    log_message(NAME, L_CRIT, "ignoring pipe signal failed\n");
......
 
The problem is fixed. Oh, it's my lucky!
