X86 After the process resumed, sleep skipped #2265

Closed hdzhoujie closed 9 months ago

hdzhoujie commented 10 months ago

Description int main(int argc, char *argv[]) { sleep(10000); printf("time out\n"); return 0;` }

The above code will be backed up and restored immediately after running. On the x86 platform, after the restoration is successful, time out will be printed directly and the program will exit without continuing to sleep and wait. There is no problem with the ARM platform.

Steps to reproduce the issue:

  1. criu dump -t 3416953 -D /home/img -o dump.log --shell-job -v4
  2. criu restore -D /home/img -o restore.log -d -j --shell-job -v4

Describe the results you received: The process prints time out and exits

Describe the results you expected: It should be the same as arm. After the process resumes, it enters sleep and waits.
