Subject: [PATCH] fs/iso9660: Set a grub_errno if mount fails
|
|
|
|
It was possible for a grub_errno to not be set if mount of an ISO 9660
|
|
filesystem failed when set_rockridge() returned 0.
|
|
|
|
This isn't known to be exploitable as the other filesystems due to
|
|
filesystem helper checking the requested file type. Though fixing
|
|
as a precaution.
