Hello It seems that the smbfs driver does not handle correctly large files (>2GB). The thing is that statting them is correct (for example, the st_size field is correctly set), but as soon as you try to make a lseek with an offset larget than INT_MAX, you get a EINVAL error.
Note: This is not coming out of the remote samba server (Tested with under windows, and it is working fine). I'm using a 2.6.10 kernel without external patches. I parsed the 2.6.11 changelog to see if this problem has been fixed, but I didn't found anything related. If this has already been discussed, just let me know ;-) You can reproduce this bug with this little program: -8<------------------------------------------ /* Enable large file support for x86 */ #define _FILE_OFFSET_BITS 64 #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> #include <unistd.h> #include <limits.h> #include <stdio.h> int main(int argc, char **argv) { int fd = open(argv[1], O_RDONLY); if(fd == -1) perror("open"); struct stat st; fstat(fd, &st); printf("filesize: %llu\n", st.st_size); /* Go at end... */ if(lseek(fd, 0, SEEK_END) == (off_t)(-1)) perror("lseek"); close(fd); return 0; } -8<------------------------------------------ Best Regards, Mathieu Fluhr - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
