fs/ext4: fix partition size get truncated in calculation

2014-01-20T15:09:38+00:00

It may cause file system corruption when do a write operation.
This issue only affects boards that use 32 bit lbaint_t.

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.

ext4: assign get_fs()->dev_desc before using it

2013-05-24T14:04:23+00:00

Commit 50ce4c0 "fs/ext4: Support device block sizes != 512 bytes"
modified ext4fs_set_blk_dev() to calculate total_sect based on
get_fs()->dev_desc->log2blksz rather than SECTOR_SIZE. However, this
value wasn't yet assigned. Move the assignment earlier so the code
doesn't crash or hang.

fs/ext4: Support device block sizes != 512 bytes

2013-05-10T12:16:33+00:00

The 512 byte block size was hard coded in the ext4 file systems.
Large harddisks today support bigger block sizes typically 4096
bytes.
This patch removes this limitation.

fs:ext4:write: Store block device descriptor in file system structure

2012-12-07T15:47:52+00:00

The device block descriptor (block_dev_desc_t) )shall be stored at
ext4 early code (at ext4fs_set_blk_dev in this case) to be available
for latter use (like put_ext4()).

cmd_extX: use common get_device_and_partition function

2012-09-25T21:46:55+00:00

Convert ext2/4 load, ls, and write functions to use common device and
partition parsing function. With the common function "dev:part" can come
from the environment and a '-' can be used in that case.

ext4: cache-align buffers so the invalidation works

2012-09-20T18:07:26+00:00

DMA buffer cache invalidation requires that buffers have cache-aligned
buffer locations and sizes. Use memalign() and ALLOC_CACHE_ALIGN_BUFFER()
to ensure this.

On Tegra at least, without this fix, the following fail commands fail in
u-boot-master/ext4, but succeeded at the branch's branch point in
u-boot/master. With this fix, the commands work again:

ext2ls mmc 0:1 /
ext2load mmc 0:1 /boot/zImage
