Andrei Borzenkov 6e21195890 progress: avoid NULL dereference for net files 
From original patch by dann frazier <dann.frazier@canonical.com>:

  grub_net_fs_open() saves off a copy of the file structure it gets passed and
  uses it to create a bufio structure. It then overwrites the passed in file
  structure with this new bufio structure. Since file->name doesn't get set
  until we return back to grub_file_open(), it means that only the bufio
  structure gets a valid file->name. The "real" file's name is left
  uninitialized. This leads to a crash when the progress module hook is called
  on it.

grub_net_fs_open() already saved copy of file name as ->net->name, so change
progress module to use it.

Also, grub_file_open may leave file->name as NULL if grub_strdup fails. Check
for it.

README 

This is GRUB 2, the second version of the GRand Unified Bootloader.
GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more
robust, more powerful, and more portable.

See the file NEWS for a description of recent changes to GRUB 2.

See the file INSTALL for instructions on how to build and install the
GRUB 2 data and program files.

Please visit the official web page of GRUB 2, for more information.
The URL is <http://www.gnu.org/software/grub/grub.html>.

More extensive documentation is available in the Info manual,
accessible using 'info grub' after building and installing GRUB 2.
Please look at the GRUB Wiki <http://grub.enbug.org> for testing
procedures.

There are a number of important user-visible differences from the
first version of GRUB, now known as GRUB Legacy. For a summary, please
see:
