return NULL for various reasons even if it has a maximum-length
buffer: for example, there might be a symlink loop, or the path
might exceed PATH_MAX. If this happens, return NULL.
* util/hostdisk.c (device_is_mapped): New function.
(find_partition_start): New function, partly broken out from
linux_find_partition and grub_util_biosdisk_get_grub_dev but with
device-mapper support added.
(linux_find_partition): Use find_partition_start.
(convert_system_partition_to_system_disk): Add `st' argument.
Support Linux /dev/mapper/* devices if device-mapper support is
available; only DM-RAID devices are understood at present.
(find_system_device): Add `st' argument. Pass it to
convert_system_partition_to_system_disk.
(grub_util_biosdisk_get_grub_dev): Pass stat result to
find_system_device and convert_system_partition_to_system_disk. Use
find_partition_start.
* conf/common.rmk (grub_mkdevicemap_SOURCES): Add kern/env.c,
kern/err.c, kern/list.c, kern/misc.c, and kern/emu/mm.c.
* util/deviceiter.c [__linux__]: Define MINOR.
(grub_util_iterate_devices): Add support for DM-RAID disk devices.
* util/mkdevicemap.c (grub_putchar): New function.
(grub_getkey): New function.
(grub_refresh): New function.
(main): Set debug=all if -v -v is used.
we handle finding grub-mkimage. Default to finding grub-mkimage in
${bindir} with program_transform_name applied, and provide a
--grub-mkimage option to override this.
mistake in r2156. Noticed by Anthony Fok.
* util/grub.d/10_kfreebsd.in (TEXTDOMAINDIR): Set to lowercased
@localedir@.
* util/grub.d/10_linux.in (TEXTDOMAINDIR): Likewise.
GRUB_DISTRIBUTOR for --class, to avoid problems if somebody puts
spaces in GRUB_DISTRIBUTOR.
* util/grub.d/10_kfreebsd.in: Likewise.
* util/grub.d/10_hurd.in: Likewise.
* util/hostdisk.c (struct grub_util_biosdisk_data): New structure.
(grub_util_biosdisk_open): Initialise disk->data.
(struct linux_partition_cache): New structure.
(linux_find_partition): Cache partition start positions; these are
expensive to compute on every read and write.
(open_device): Cache open file descriptor in disk->data, so that we
don't have to reopen it and flush the buffer cache for consecutive
operations on the same device.
(grub_util_biosdisk_close): New function.
(grub_util_biosdisk_dev): Set `close' member.
* conf/common.rmk (grub_probe_SOURCES): Add kern/list.c.
* conf/i386-efi.rmk (grub_setup_SOURCES): Likewise.
* conf/i386-pc.rmk (grub_setup_SOURCES): Likewise.
* conf/sparc64-ieee1275.rmk (grub_setup_SOURCES): Likewise.
* conf/x86_64-efi.rmk (grub_setup_SOURCES): Likewise.
* util/hostdisk.c (struct grub_util_biosdisk_data): New structure.
(grub_util_biosdisk_open): Initialise disk->data.

(grub_util_biosdisk_close): New function.
(grub_util_biosdisk_dev): Set `close' member.
* conf/common.rmk (grub_probe_SOURCES): Add kern/list.c.
* conf/i386-efi.rmk (grub_setup_SOURCES): Likewise.

* conf/x86_64-efi.rmk (grub_setup_SOURCES): Likewise.
* util/grub-mkconfig.in (GRUB_SAVEDEFAULT): Export new variable.
* util/grub-mkconfig_lib.in (save_default_entry): Only save a new
default entry if GRUB_SAVEDEFAULT=true. This allows using
GRUB_DEFAULT=saved on its own to let grub-reboot work, without
saving a new default on every boot.
2010-02-10 Colin Watson <cjwatson@ubuntu.com>
Shrink the pre-partition-table part of boot.img by eight bytes.
* boot/i386/pc/boot.S (ERR): New macro.
(chs_mode): Use ERR.
(geometry_error): Likewise.
(hd_probe_error): Remove. This is only used once, so we wrwite
it inline instead.
(read_error): Instead of printing read_error_string, just set up
%si and fall through to ...
(error_message): ... this new function, also used by ERR.
* util/grub.d/10_linux.in: This script does not use any of the
contents of gettext.sh, only the external command `gettext', so stop
sourcing it. (Moreover, gettext.sh isn't necessarily installed in
the same prefix as GRUB.)
* util/grub.d/10_kfreebsd.in: Likewise.
* conf/common.rmk (grub_mkdevicemap_SOURCES): Add kern/env.c,
kern/err.c, kern/list.c, and kern/misc.c.
* util/deviceiter.c [__linux__]: Define MINOR.
(grub_util_iterate_devices): Add support for DM-RAID disk devices.
* util/mkdevicemap.c (grub_putchar): New function.
(grub_getkey): New function.
(grub_refresh): New function.
(main): Set debug=all if -v -v is used.
* configure.ac: Check for Linux device-mapper support.
* util/hostdisk.c (device_is_mapped): New function.
(find_partition_start): New function, partly broken out from
linux_find_partition and grub_util_biosdisk_get_grub_dev but with
device-mapper support added.
(linux_find_partition): Use find_partition_start.
(convert_system_partition_to_system_disk): Add `st' argument.
Support Linux /dev/mapper/* devices if device-mapper support is
available; only DM-RAID devices are understood at present.
(find_system_device): Add `st' argument. Pass it to
convert_system_partition_to_system_disk.
(grub_util_biosdisk_get_grub_dev): Pass stat result to
find_system_device and convert_system_partition_to_system_disk. Use
find_partition_start.
* kern/device.c (grub_device_iterate): Allocate new part_ent
structure based on sizeof (*p) rather than sizeof (p->next), to
account for structure padding.
* util/grub-probe.c (probe_raid_level): Return -1 immediately if
disk is NULL, which might happen for LVM physical volumes with no
LVM signature.
* util/mkisofs/write.c (padblock_write): Switch size and nmemb
arguments to fread so that we get a return value in bytes, rather
than something that will normally be rounded down to 0.
Adjust error handling to avoid producing garbage when size_t is not
the same size as long long.

* util/grub.d/00_header.in: Define a "savedefault" function for use
in menu entries.
* util/grub-mkconfig_lib.in (save_default_entry): Use it.
2010-10-05 Colin Watson <cjwatson@ubuntu.com>
* util/grub-mkconfig_lib.in (save_default_entry): Only set
saved_entry if boot_once is unset.
* util/grub.d/00_header.in: Set boot_once to "true" if there was a
previous saved entry (i.e. grub-reboot).
* util/grub-mkconfig_lib.in: Don't set grub_probe or grub_mkrelpath
if they're already set. This resolves the conflict between my
grub-install change on 2009-10-06 and Felix' change on 2009-11-11,
fixing the --grub-probe option again.
* util/sparc64/ieee1275/grub-install.in: Revert the last piece of my
change on 2009-10-06, so that we now once again source
`${libdir}/grub/grub-mkconfig_lib' after options have been parsed.
