This fixes a performance issue when pc & gpt partmap iterators
didn't abort iteration even after our hook found what it was
looking for (often causing expensive probes of non-existant drives).
Some callers relied on previous buggy behaviour, since they would
rise an error when their own hooks caused early abortion of its
iteration.
* kern/device.c (grub_device_open): Improve error message.
* disk/lvm.c (grub_lvm_open): Likewise.
* disk/raid.c (grub_raid_open): Likewise.
* partmap/pc.c (pc_partition_map_iterate): Abort parent iteration
when hook requests it, independently of grub_errno.
(pc_partition_map_probe): Do not fail when find_func() caused
early abortion of pc_partition_map_iterate().
* partmap/gpt.c (gpt_partition_map_iterate): Abort parent iteration
when hook requests it, independently of grub_errno.
(gpt_partition_map_probe): Do not fail when find_func() caused
early abortion of gpt_partition_map_iterate().
* kern/partition.c (grub_partition_iterate): Abort parent iteration
when hook requests it, independently of grub_errno. Do not fail when
part_map_iterate_hook() caused early abortion of p->iterate().
* util/biosdisk.c (grub_util_biosdisk_get_grub_dev): Do not fail
when grub_partition_iterate() returned with non-zero.
* util/biosdisk.c (open_device): Revert last change to the
function, it broke installation. The sector needs to be
different dependent on which device is opened.
* util/biosdisk.c (get_drive): Verify that `map[i].drive' is non-NULL
before dereferencing it.
* fs/fat.c (struct grub_fat_bpb): Move fat32-specific fields into a
union with fat12/fat16-specific ones. Add some new fields, including
`num_serial' for both versions.
(struct grub_fat_data): Add `uuid' member.
(grub_fat_mount): Refer to fat32-specific fields in `bpb' by their new
names. Initialize `data->uuid' using `num_serial'.
(grub_fat_uuid): New function.
(grub_fat_fs): Reference grub_fat_uuid() in `uuid' struct member.
* fs/reiserfs.c (grub_reiserfs_superblock): Add `uuid' field.
(grub_reiserfs_uuid): New function.
(grub_reiserfs_fs): Reference grub_reiserfs_uuid() in `uuid' struct
member.
* fs/xfs.c (grub_xfs_sblock): Add `uuid' field.
(grub_xfs_uuid): New function.
(grub_xfs_fs): Reference grub_reiserfs_uuid() in `uuid' struct member.
* util/biosdisk.c (linux_find_partition): Simplify logic and
make the code more universal. Keep special processing for
devfs, but use a simple rule for all other devices. If the
device ends with a number, append 'p' and the partition number.
Otherwise, append only the partition number.
* util/biosdisk.c (map): Redefine structure to hold information
about GRUB drive name.
(get_drive): Reimplement without assuming (and verifiing) BIOS-like
drive names.
(call_hook): Remove.
(grub_util_biosdisk_iterate): Access drive names via `.drive' struct
member. Assume drive has partitions.
(grub_util_biosdisk_open): Access device names via `.device' struct
member.
(open_device): Likewise.
(find_drive): Likewise.
(read_device_map): Adjust map[] usage to match the new struct
definition. Don't check for duplicates (still possible, but not cheap
anymore).
(grub_util_biosdisk_fini): Free malloced buffers referenced by map[].
(make_device_name): Remove assumption of BIOS-like drive names.
* util/biosdisk.c: [__CYGWIN__] Add includes.
(grub_util_biosdisk_open): Use Linux code also for Cygwin.
(get_os_disk): Move variable declarations to OS specific
parts to avoid warning.
[__GNU__] (get_os_disk): Fix /dev/sdXsN case.
[__CYGWIN__] (get_os_disk): Add Cygwin /dev/sdXN device names.
(grub_util_biosdisk_get_grub_dev): Use Linux code also for
Cygwin.
* util/getroot.c: [__CYGWIN__] Add includes.
(strip_extra_slashes): Fix "/" case.
[__CYGWIN__] (get_win32_path): New function.
[__CYGWIN__] (grub_get_prefix): Add conversion to win32 path.
[__CYGWIN__] (find_root_device): Disable.
[__CYGWIN__] (get_bootsec_serial): New function.
[__CYGWIN__] (find_cygwin_root_device): Likewise.
[__linux__] (grub_guess_root_device): Add early returns to simplify
structure.
[__CYGWIN__] (grub_guess_root_device): Call find_cygwin_root_device.
[__linux__] (grub_util_get_dev_abstraction): Enable LVM and RAID
check for Linux only.
* util/biosdisk.c (get_os_disk): Recognise xvd type disks.
* util/grub-mkdevicemap.c (get_xvd_disk_name): New function.
(make_device_map): Output entries for xvd type disks.
* util/biosdisk.c: Include grub/util/biosdisk.h.
* util/grub-fstest.c (execute_command): Make static.
* util/grub-mkdevicemap.c (check_device): Likewise.
* util/i386/pc/misc.c: Include grub/machine/init.h.
* util/powerpc/ieee1275/misc.c: Likewise.
* util/lvm.c: Include grub/util/lvm.h.
* util/misc.c: Include grub/kernel.h, grub/misc.h and
grub/cache.h.
* util/raid.c: Include grub/util/raid.h.
(grub_util_getdiskname): Make static.
* util/biosdisk.c (grub_util_biosdisk_open, linux_find_partition)
(grub_util_biosdisk_get_grub_dev): Check open() exit status by
comparing it with -1, not 0.
* normal/command.c (grub_command_execute): Use NULL rather than 0 for
"pager" assignment.
* util/biosdisk.c (grub_util_biosdisk_get_grub_dev): Likewise for
"pcdata".
* util/grub-probe.c (probe): Likewise for "drive_name".
* conf/powerpc-ieee1275.rmk: Enable grub-mkdevicemap and grub-probe.
* include/grub/partition.h: Declare grub_apple_partition_map_init and
grub_apple_partition_map_fini.
* util/biosdisk.c
(grub_util_biosdisk_open): Replace BLKGETSIZE with BLKGETSIZE64 (needed
to access >2 TiB disks).
Print disk->total_sectors with %llu instead of %lu, since this
variable is always 64-bit (prevents wrong disk size from being displayed
on either >2 TiB disk or big-endian CPU).
(grub_util_biosdisk_get_grub_dev): Convert gpt_partition_map handling
into a generic case that supports all (sane) partition maps.
Stop using grub_cpu_to_le32() on dos_part / bsd_part since it actually
breaks big-endian.
* util/grub-probe.c: Call grub_apple_partition_map_init() before probe()
and grub_apple_partition_map_fini() after that.
* util/biosdisk.c (linux_find_partition): Allocate real_dev on the
stack instead of on the heap.
* kern/disk.c (grub_disk_read): Make sure tmp_buf is big enough
before doing a read on it.
* configure.ac: Only use -fno-stack-protector for the target
environment.
