disk: Fix possible out-of-bounds access in part_efi.c

2013-06-04T20:06:32+00:00

Make sure to never access beyond bounds of either EFI partition name
or DOS partition name. This situation is happening:

part.h:     disk_partition_t->name is 32-byte long
part_efi.h: gpt_entry->partition_name is 36-bytes long

The loop in part_efi.c copies over 36 bytes and thus accesses beyond
the disk_partition_t->name .

Fix this by picking the shortest of source and destination arrays and
make sure the destination array is cleared so the trailing bytes are
zeroed-out and don't cause issues with string manipulation.

disk/iso: Add Support for block sizes > 512 byte to ISO partition support

2013-05-01T20:24:02+00:00

For ISO we check the block size of the device if this is != the CD sector
size we assume that the device has no ISO partition.

disk/gpt: Fix GPT partition handling for blocksize != 512

2013-05-01T20:24:02+00:00

Disks beyond 2T in size use blocksizes of 4096 bytes. However a lot of
code in u-boot  still assumes a 512 byte blocksize.
This patch fixes the handling of GPTs.

disk/part_dos: check harder for partition table

2013-05-01T20:24:01+00:00

Devices that used to have a whole disk FAT filesystem but got then
partitioned will most likely still have a FAT or FAT32 signature
in the first sector as this sector does not get overwritten by
a partitioning tool (otherwise the tool would risk to kill the mbr).

The current partition search algorithm will erronously detects such
a device as a raw FAT device.

Instead of looking for the FAT or FAT32 signatures immediately we
use the same algorithm as used by the Linux kernel and first check
for a valid boot indicator flag on each of the 4 partitions.
If the value of this flag is invalid for the first entry we then
do the raw partition check.
If the flag for any higher partition is wrong we assume the device
is neiter a MBR nor PBR device.

disk: fix unaligned access in efi partitions

2013-04-02T20:23:34+00:00

start_sect is not aligned to a 4 byte boundary thus causing exceptions
on ARM platforms. Access this field via the get_unaligned_le32 macro.

disk: define HAVE_BLOCK_DEVICE in a common place

2013-03-14T18:06:44+00:00

This set of ifdefs is used in a number of places. Move its definition
somewhere common so it doesn't have to be repeated.

The restoration of GPT table (both primary and secondary) is now possible.
Function 'gpt_restore' presents example of partition restoration process.

part:efi: Move part_efi.h file to ./include

2012-12-13T18:46:02+00:00

This move is necessary to export gpt header and GPT partition entries to be
used with other commands or subsystems.
Additionally the part_efi.h file has been cleaned-up to supress checkpatch's
warnings.
