You're saying that you're running as root? So, on your host root
doesn't have the ability to set the time on "/proc/self/fd/0"? That
sounds a bit strange. Root should be able to do anything, right?
Can you reproduce this problem with a small C program? Something like
this. Please run it as root, in the same directory, etc. You can use
strace to verify that it has the same system calls.
#include <fcntl.h>
#include <stdio.h>
#include <sys/time.h>
#include <unistd.h>
int
main (void)
{
close (0);
if (open ("D/a", O_WRONLY|O_NONBLOCK|O_CREAT|O_NOCTTY, 0666) != 0)
perror ("open");
else if (utimes ("/proc/self/fd/0", 0) != 0)
perror ("utimes");
return 0;
}
