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

2013-07-22T14:09:30+00:00

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

2013-07-15T21:06:13+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.

Consolidate bool type

2013-04-01T20:33:52+00:00

'bool' is defined in random places. This patch consolidates them into a
single header file include/linux/types.h, using stdbool.h introduced in C99.

All other #define, typedef and enum are removed. They are all consistent with
true = 1, false = 0.

Replace FALSE, False with false. Replace TRUE, True with true.
Skip *.py, *.php, lib/* files.

fs: Move ls and read methods into ext4, fat

2013-03-04T19:19:56+00:00

It doesn't make a lot of sense to have these methods in fs.c. They are
filesystem-specific, not generic code. Add each to the relevant
filesystem and remove the associated #ifdefs in fs.c.

ext4: Split write support into its own file

2013-03-04T19:19:56+00:00

This code seems to be entirely othogonal, so remove the #ifdef and put
the condition in the Makefile instead.

fs:ext4:write: Initialize cache aligned filename buffer

2012-12-07T15:47:53+00:00

The filename buffer is allocated dynamically. It must be cache aligned.
Moreover, it is necessary to erase its content before we use it for
file name operations.

This prevents from corruption of written file names.

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()).
