stat() fails on cifs shares

[demidrol]

Binary package hint: samba

I noticed that after upgrade from linux-image-2.6.29 to linux-image-2.6.32-4-generic some programs that recursively scan directories (like mpd, xmms2 or gqview) stopped working on samba shares. They simply doesn't see the mountpoint (e.g. if I mount //server/share on /mnt/mountpoint and navigate gqview to /mnt it does not see mountpoint subdirectory). I suspect that this is somehow connected with strange behavior of stat() system call. The following code

#include <stdio.h>
#include <stdlib.h>

#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>

int main(int argc, char* argv[]){
    struct stat stat_buf;
    if (argc != 2)
        exit(-1);
    if (stat(argv[1], &stat_buf) != 0){
        perror(NULL);
        exit(-1);
    }
    return 0;
}

fails on samba shares (e.g. if I try to execute ./a.out /mnt/mountpoint I get "Value too large for defined data type").

Having the same problem in Ubuntu Karmic (kernel 2.6.31-14-generic). Many programs (e.g.: gedit, tex, octave) don't work over cifs shares.

It's a very nasty bug for those of us using cifs shares.

Status changed to 'Confirmed' because the bug affects multiple users.
