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

| ext4fs: fix "invalid extent block" error
|
| For files where we actually have extent indexes following
| an extent header (ext_block->eh_depth != 0), the do/while
| loop from ext4fs_get_extent_block() does not select the
| proper extent index structure.
|
| For example, if we have:
|
| ext_block->eh_depth = 1
| ext_block->eh_entries = 1
| fileblock = 0
| index[0].ei_block = 0
|
| the do/while loop will exit with i set to 0 and the
| ext4fs_get_extent_block() function will return 0, even if
| there was a valid extent index structure following the
| header.

automount_mount calls run_command which may trigger an automount
again. This results in an endless loop. A simple way to trigger
this is:
mkdir /x; automount /x false; cd /x; something
Use a static variable to detect if we are currently in automount_mount()
and bail out if we are.

Compared to devfs_add_partition which adds a single partition
devfs_create_partitions creates several partitions at once. One nice
benefit is that this simplifies appending partitions because the start
of the latter partition doesn't need to be specified explicitly.
Also dev_add_bb_dev() is called by the new helper if the bbname is
specified for a partition.
Note that adding partitions is also more flexible now (also via
devfs_add_partition) because negative values for offset and size now
have a proper meaning instead of creating broken partitions.

Since this commit copy_file passes O_TRUNC to open(). This results in the
fs layer calling fsdrv->truncate. tftp returns -ENOSYS here and open returns
with an error. To fix this return 0 for the truncate callback in tftp. Also
enforce the O_TRUNC flag when opening a file for writing on tftp as the files
are always truncated on tftp anyway.

Simple update file format developed for Somfy, tools and library are
available under LGPLv2 (https://www.gitorious.org/libbpk).
This format in the v1.0 allow you to store 6 types a binary stream for
a unique hardware id:
- bootloader
- bootloader_version
- description.gz
- kernel
- rootfs
- firmware_version
and you can easly add more binary stream type.
The fs will display you in a directory per hw id
and if a binary stream type is unknown will be display
as unknown_%08x
# mount image.bpk /tmp
# ls -l /tmp/hw_id_0/
-rwxrwxrwx 10 firmware_version
-rwxrwxrwx 8 firmware_version.crc
-rwxrwxrwx 1845968 kernel
-rwxrwxrwx 8 kernel.crc
-rwxrwxrwx 5062656 rootfs

-rwxrwxrwx 8 bootloader.crc
-rwxrwxrwx 248925 description.gz

-rwxrwxrwx 4 bootloader_version
-rwxrwxrwx 8 bootloader_version.crc
-rwxrwxrwx 4 unknown_1234567g
-rwxrwxrwx 8 unknown_1234567g.crc
Why BPK and not CPIO or uImage
1) CPIO
cpio does not handle > 4GiB image and does not have any crc checksum
2) uImage
uImage only provide one crc32 for the all data part and only a list of binary
stream with no information about what is what (in multi-image format)
3) BPK
BPK provide a crc32 for the header part and one crc32 per binary stream
so if you does not care of some data you are not force to check them
And you known exactly the binary stream type and for which hw to
use it.

All filesystem drivers which need a backingstore device do the same
ignoring of '/dev/' in the backingstore followed by a cdev_open. Add a
helper function for it and let the core handle the cdev. As a side
effect this makes sure that fsdev->cdev is also set when a device is
mounted without the leading '/dev/' which was previously ignored
by the mount code.
