Description

CRIU (Checkpoint/Restore In Userspace) is not properly handling one-shot interval timers (ITIMERs) during checkpoint and restore operations. Specifically, timers that have their it_interval set to zero but a non-zero it_value are being ignored.

The bug affects timers with the following characteristics:

  • it_interval.sec == 0
  • it_interval.usec == 0
  • it_value.sec != 0 OR it_value.usec != 0

Steps to reproduce the issue:
This piece of c code repros it. Try checkpointing in the middle of the execution. And restore it. It should continue counting down after restoration.

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <signal.h>
#include <sys/time.h>

void timer_handler(int signum) {
    printf("Hello\n");
    exit(0);
}

int main() {
    struct itimerval timer;
    struct sigaction sa;

    // Set up the timer handler
    sa.sa_handler = timer_handler;
    sigemptyset(&sa.sa_mask);
    sa.sa_flags = 0;
    sigaction(SIGALRM, &sa, NULL);

    // Set the timer for 30 seconds
    timer.it_value.tv_sec = 30;
    timer.it_value.tv_usec = 0;
    timer.it_interval.tv_sec = 0;
    timer.it_interval.tv_usec = 0;

    // Start the timer
    if (setitimer(ITIMER_REAL, &timer, NULL) == -1) {
        perror("setitimer");
        return 1;
    }

    printf("Timer set for 30 seconds\n");

    // Loop every second to check remaining time
    while (1) {
        sleep(1);
        
        if (getitimer(ITIMER_REAL, &timer) == -1) {
            perror("getitimer");
            return 1;
        }
        
        printf("Time remaining: %ld seconds\n", timer.it_value.tv_sec);
    }

    return 0;
}

Describe the results you received:

Time remaining: 0 seconds
Time remaining: 0 seconds
Time remaining: 0 seconds
Time remaining: 0 seconds
...

Describe the results you expected:

Time remaining: 20 seconds
Time remaining: 19 seconds
Time remaining: 18 seconds
Time remaining: 17 seconds
...
