Hi,
There is a testcase issue in the event_generator code. The gen_fork() is
called to generate the fork event.
The child process prints the following message:
static inline void gen_fork(void)
{
pid_t pid;
int status;
pid = fork();
if (pid == 0) {
printf("fork parent: %d, child: %d\n", getppid(),
getpid());
exit(0);
} else if (pid < 0) {
fprintf(stderr, "fork() failed\n");
exit(1);
}
}
Now the parent process just exits after this call. So, if the child
doesn't get to run before parent exits, the child will see the ppid as
1, that of INIT and this contradicts the actual data. Hence the test fails.
Attached patch fixes the issue. I have verified the same. Please apply.
Thanks
Suzuki
