GRUB_EFI_IMAGE_HANDLE to grub_efi_get_loaded_image.
* kern/efi/efi.c (grub_efi_get_loaded_image): Accept a new
argument IMAGE_HANDLE and specify it to get a loaded image.
(grub_arch_modules_addr): Specify GRUB_EFI_IMAGE_HANDLE to
grub_efi_get_loaded_image.
(grub_efi_get_filename): Divide the legnth by the size of
grub_efi_char16_t.
(grub_efi_get_device_path): New function.
(grub_efi_print_device_path): Print End Device Path nodes. Divide
the length by the size of grub_efi_char16_t for a file path device
path node.
* kern/loader.c (grub_loader_noreturn): New variable.
(grub_loader_set): Accept a new argument NORETURN. Set
GRUB_LOADER_NORETURN to NORETURN.
All callers changed.
(grub_loader_boot): If GRUB_LOADER_NORETURN is false, do not call
grub_machine_fini.
* include/grub/efi/efi.h (grub_efi_get_device_path): New
prototype.
(grub_efi_get_loaded_image): Take an argument to specify an image
handle.
* include/grub/loader.h (grub_loader_set): Added one more argument
NORETURN.
* disk/efi/efidisk.c (make_devices): Use grub_efi_get_device_path
instead of grub_efi_open_protocol.
(grub_efidisk_get_device_name): Likewise.
(grub_efidisk_close): Print a newline.
(grub_efidisk_get_device_handle): Fixed to use
GRUB_EFI_DEVICE_PATH_SUBTYPE instead of
GRUB_EFI_DEVICE_PATH_TYPE.
* disk/efi/efidisk.c (device_path_guid): Moved to ...
* kern/efi/efi.c (device_path_guid): ... here.
* conf/i386-efi.rmk (pkgdata_MODULES): Added _chain.mod and
chain.mod.
(kernel_mod_HEADERS): Added efi/disk.h.
(_chain_mod_SOURCES): New variable.
(_chain_mod_CFLAGS): Likewise.
(_chain_mod_LDFLAGS): Likewise.
(chain_mod_SOURCES): Likewise.
(chain_mod_CFLAGS): Likewise.
(chain_mod_LDFLAGS): Likewise.
* DISTLIST: Added include/grub/efi/chainloader.h,
loader/efi/chainloader.c and loader/efi/chainloader_normal.c.
* include/grub/efi/chainloader.h: New file.
* loader/efi/chainloader.c: Likewise.
* loader/efi/chainloader_normal.c: Likewise.
* commands/configfile.c (grub_cmd_source): New function.
(GRUB_MOD_INIT): Register the commands `source' and `.'.
(GRUB_MOD_FINI): De-register the commands `source' and `.'.
* normal/execute.c (grub_script_execute_cmd): Change the return
type to `grub_err_t'. Correctly return the error.
(grub_script_execute_cmdline): In case a command line is not a
command or a function, try to interpret it as an assignment.
* fs/hfsplus.c (grub_hfsplus_read_block): Fixed a memory leak.
(grub_hfsplus_iterate_dir): Reordered to skip unknown nodes. Also,
skip a node whose name is obviously invalid as UTF-16,
i.e. contains a NUL character. Stop the iteration when the last
directory entry is found. Instead of using the return value of
grub_hfsplus_btree_iterate_node, store the value in RET and use
it, because the iterator can be stopped by the last directory
entry.
