[U-Boot] [PATCH] Fix ext2/ext4 filesystem accesses beyond 2TiB
Frederic Leroy
fredo at starox.org
Mon Jun 24 23:26:40 CEST 2013
From: Frédéric Leroy <fredo at starox.org>
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.
---
This patch applies on top of Sascha one.
It has been tested with CONFIG_SYS_64BIT_LBA disabled on a small
disk and CONFIG_SYS_64BIT_LBA enabled on a 3TB disk on a LaCie
arm platform. Moreover, CONFIG_CMD_EXT4 and CONFIG_FS_EXT4 was enabled.
Both compilation issue no warning.
For the 3TB setup, 3 partition have been created beyond the 2.1TiB limit.
One partition ext2, one ext4, and one vfat. Each one filled with an
uImage kernel.
For all partition, commands fatls and ext2ls did work, as well as loading
and booting uImage.
