Hello,
The following program shows:
create: Success
open: Stale NFS file handle
but the expected result is
create: Success
open: Success
Code:
#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <unistd.h>
int main()
{
int fd1, fd2;
const char *filename = "opentest.tmp";
char buf[256];
fd1 = open(filename, O_RDWR | O_CREAT, S_IRUSR | S_IWUSR);
perror("create");
remove(filename);
sprintf(buf, "/proc/%d/fd/%d", (int)getpid(), fd1);
fd2 = open(buf, O_RDWR | O_CREAT, S_IRUSR | S_IWUSR);
perror("open");
close(fd2);
close(fd1);
return 0;
}
This only happens on aufs (tested version is 3.12-20131111), config
CONFIG_AUFS_FS=m
CONFIG_AUFS_BRANCH_MAX_127=y
# CONFIG_AUFS_BRANCH_MAX_511 is not set

CONFIG_AUFS_SBILIST=y

CONFIG_AUFS_EXPORT=y
CONFIG_AUFS_RDU=y
# CONFIG_AUFS_SP_IATTR is not set

CONFIG_AUFS_BR_FUSE=y
CONFIG_AUFS_POLL=y
CONFIG_AUFS_BR_HFSPLUS=y
CONFIG_AUFS_BDEV_LOOP=y
# CONFIG_AUFS_DEBUG is not set
Will provide more details if necessary.
