part_efi: make sure the gpt_pte is freed

2013-09-20T14:30:53+00:00

the gpt_pte wasn't being freed if it was checked against an invalid
partition. The resulting memory leakage could make it impossible
to repeatedly attempt to load non-existent files in a script.

Also, downgrade the message for not finding an invalid partition
from a printf() to a debug() so as to minimize message spam in
perfectly normal situations.

Fix ext2/ext4 filesystem accesses beyond 2TiB

2013-07-15T21:06:13+00:00

With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type,
which is required to represent block numbers for storage devices that
exceed 2TiB (the block size usually is 512B), e.g. recent hard drives

We now use lbaint_t for partition offset to reflect the lbaint_t change,
and access partitions beyond or crossing the 2.1TiB limit.
This required changes to signature of ext4fs_devread(), and type of all
variables relatives to block sector.

ext2/ext4 fs uses logical block represented by a 32 bit value. Logical
block is a multiple of device block sector. To avoid overflow problem
when calling ext4fs_devread(), we need to cast the sector parameter.

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/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: 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.
