ext4fs: le32_to_cpu() used on a 16-bit field

2013-07-22T14:09:30Z

Fix reading ext4_extent_header struture on BE machines. Some 16 bit fields where converted to 32 bit fields, due to the byte swap on BE machines the containing value was corrupted. Therefore reading ext4 filesystems on BE machines where broken before.

Fix ext2/ext4 filesystem accesses beyond 2TiB

2013-07-15T21:06:13Z

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. Signed-off-by: Frédéric Leroy

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

2013-05-10T12:16:33Z

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. Signed-off-by: Egbert Eich

fs: separate CONFIG_FS_{FAT, EXT4} from CONFIG_CMD_{FAT, EXT*}

2012-10-29T21:21:19Z

This makes the FAT and ext4 filesystem implementations build if CONFIG_FS_{FAT,EXT4} are defined, rather than basing the build on whether CONFIG_CMD_{FAT,EXT*} are defined. This will allow the filesystems to be built separately from the filesystem-specific commands that use them. This paves the way for the creation of filesystem-generic commands that used the filesystems, without requiring the filesystem- specific commands. Minor documentation changes are made for this change. The new config options are automatically selected by the old config options to retain backwards-compatibility.

ext4: Rename block group descriptor table from gd to bgd

2012-10-04T01:21:33Z

On x86 machines gd is unfortunately a #define, so we should avoid using gd for anything. This patch changes uses of gd to bgd so that ext4fs can be used on x86. A better fix would be to remove the #define in x86, but I'm not sure how to do that. Signed-off-by: Simon Glass

ext4: cache-align buffers so the invalidation works

2012-09-20T18:07:26Z

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 Cc: Uma Shankar Cc: Manjunatha C Achar Cc: Iqbal Shareef Cc: Hakgoo Lee Cc: Wolfgang Denk Cc: Tom Rini Signed-off-by: Stephen Warren
