* ext4: Update ext2/3/4 superblock, group descriptor and inode structuresStefan Brüns2016-09-23-4/+46
| | | | | | | Most importantly, the superblock provides the used group descriptor size, which is required for the EXT4_FEATURE_INCOMPAT_64BIT. Signed-off-by: Stefan Brüns <stefan.bruens@rwth-aachen.de>
* ext4: Use correct value for inode size even on revision 0 filesystemsStefan Brüns2016-09-23-2/+0
| | | | | | | | fs->inodesz is already correctly (i.e. dependent on fs revision) initialized in ext4fs_mount. Signed-off-by: Stefan Brüns <stefan.bruens@rwth-aachen.de> Reviewed-by: Lukasz Majewski <l.majewski@samsung.com>
* ext4: fix endianess problems in ext4 write supportMichael Walle2016-09-23-1/+1
| | | | | | | | 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. Signed-off-by: Michael Walle <michael@walle.cc>
* ext4: use kernel names for byte swapsMichael Walle2016-09-23-2/+2
| | | | | | Instead of __{be,le}{16,32}_to_cpu use {be,le}{16,32}_to_cpu. Signed-off-by: Michael Walle <michael@walle.cc>
* ext4: change structure fields to __le/__be typesMichael Walle2016-09-23-68/+68
| | | | | | | | 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. Signed-off-by: Michael Walle <michael@walle.cc>

* Fix ext2/ext4 filesystem accesses beyond 2TiBFrederic Leroy2013-07-15-1/+1
| | | | | | | | | | | | | | | | | 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 <fredo@starox.org>
* fs/ext4: Support device block sizes != 512 bytesEgbert Eich2013-05-10-9/+3
| | | | | | | | | 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 <eich@suse.com>
* fs: add filesystem switch libary, implement ls and fsload commandsStephen Warren2012-10-29-3/+0
| | | | | | | | | | | | 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. Signed-off-by: Stephen Warren <swarren@nvidia.com>
* cmd_extX: use common get_device_and_partition functionRob Herring2012-09-25-0/+2
| | | | | | | | 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. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
