ext4: Update ext2/3/4 superblock, group descriptor and inode structures

2016-09-23T13:18:55+00:00

Most importantly, the superblock provides the used group descriptor size,
which is required for the EXT4_FEATURE_INCOMPAT_64BIT.

ext4: Use correct value for inode size even on revision 0 filesystems

2016-09-23T13:02:42+00:00

fs->inodesz is already correctly (i.e. dependent on fs revision)
initialized in ext4fs_mount.

ext4: fix endianess problems in ext4 write support

2016-09-23T13:02:04+00:00

All fields were accessed directly instead of using the proper byte swap
functions. Thus, ext4 write support was only usable on little-endian
architectures. Fix this.

ext4: use kernel names for byte swaps

2016-09-23T13:02:02+00:00

Instead of __{be,le}{16,32}_to_cpu use {be,le}{16,32}_to_cpu.

ext4: change structure fields to le/be types

2016-09-23T13:02:01+00:00

Change all the types of ext2/4 fields to little endian types and all the
JBD fields to big endian types. Now we can use sparse (make C=1) to check
for statements where we need byteswaps.

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.

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: add filesystem switch libary, implement ls and fsload commands

2012-10-29T21:21:20+00:00

Implement "ls" and "fsload" commands that act like {fat,ext2}{ls,load},
and transparently handle either file-system. This scheme could easily be
extended to other filesystem types; I only didn't do it for zfs because
I don't have any filesystems of that type to test with.

Replace the implementation of {fat,ext[24]}{ls,load} with this new code
too.

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.
