Description of problem:
After updating the kernel version >= 2.6.11 (so FC3 has the
same problem), under a C program, when I use write() or fwrite()
(or some other low level C write fonction) to write a buffer
beyond 2147483648 bytes, program fails with error message
: invalid argument.

Solution I used now is just downgrading to a 2.6.10 kernel.

My Athlon64 box config: 4 Giga bytes memory with a athlon64 3500+.


Sample program:
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#include <fcntl.h>
#include <errno.h>


int main (int argc, char *argv[])
{
  int fd;
  size_t size_to_wrt;
  void *buffer_to_wrt;
  ssize_t size_wrten;

  size_to_wrt = 2147483648; /* can not beyond 2147483647 bytes */
  buffer_to_wrt = malloc(size_to_wrt);
  if(buffer_to_wrt == NULL) printf("Malloc error\n");

      
  fd  = open(argv[1],  O_CREAT | O_RDWR, S_IRUSR|S_IWUSR);
  size_wrten = write(fd, buffer_to_wrt, size_to_wrt);
  if(size_wrten != size_to_wrt)
   printf("Error message: %s\n", strerror(errno));
  free(buffer_to_wrt);
  close(fd);
  
  return 0;
}





Version-Release number of selected component (if applicable):
if kernel version >= 2.6.11

How reproducible:
Always

Steps to Reproduce:
1. A athlon64 PC has more that 2 Gbytes memory.
2. Compile ths sample C program. 
   (cc -o test_64bit_write test_64bit_write.c)
3. Execute with: test_64bit_write foo.

  

Actual Results:  error message
test_64bit_write : invalid argument.


Expected Results:  Program pass.
