>Description:
Multiple sequence of mkdir and rmdir causes mkdir failure with errno 31. Usualy it happens on 32765 iteration.
>How-To-Repeat:
Compile and execute the following program:
#include <sys/stat.h>
#include <unistd.h>
#include <stdio.h>
#include <errno.h>
int main (void)
{
int i;
char dir[100];
for (i = 0; i < 50000; i++)
{
snprintf (dir, sizeof(dir), "empty_dir/%d", i);
printf ("%s\n", dir);
if (mkdir (dir, 0700) == -1)
{
printf ("mkdir %s: (errno %d)\n", dir, errno);
break;
}
if (rmdir (dir) == -1)
{
printf ("rmdir %s: (errno %d)\n", dir, errno);
break;
}
}
return 0;
}
gcc -o test1 test1.c
mkdir empty_dir
./test1
