d8286a993a package/genext2fs: add host variant
genext2fs is built only if the user selected an ext2 root filesystem.

However, some use-cases can't live with the full target/ dir on the
root filesystem, and requires separate partitions (eg. for /usr).
In this case, the user would not select an ext2 root fs in the
Buildrooot menu, and would only generate a tarball of the rootfs.
This tarball would then be used from a post-image script to build
the actual required FSes.

But then, genext2fs is not built, since the ext2 root FS was not
selected.

As for the other filesystem generators, provide a host variant of
genext2fs (genext2fs is already host-package aware, so only needs
adding a Kconfig entry).

60474dcec6 fs/ext2: further fix to the UUID
Turned out that setting a nil-UUID is no better than clearing it.

What currently happens is as follows:
  - first, genext2fs does not generate a UUID
  - then we tune2fs to upgrade the filesystem
  - then we run fsck, which generates a random UUID
  - then we re-run tune2fs to set a nil-UUID

So, on the target, if the file system is improperly unmounted (eg.
with a power failure), on next boot, fsck may be run, and a new
random UUID will be generated.

*However*, fsck improperly updates the filesystem when it adds the
UUID, and there are a few group descriptor checksum errors.

Those errors will go undetected until the next fsck, which will then
block for user input (bad on embedded systems, bad).

Fix that by systematically generating a random UUID _before_ we call
to fsck.

A random UUID is not so bad, after all, since there are already so
many sources of unpredictability in the filesystem: files date and
ordering, files content (date, paths...) which renders a fixed UUID
unneeded.

And it is still possible to set the UUID in a post-image script if
needed, anyway.

a9825c06b8 fs/ext2: explicitly set a NULL UUID
"tune2fs -U clear" creates an invalid filesystem, that fsck.ext2
whines about later:

    $ make rootfs-ext2
    [--SNIP--]

    $ ./host/usr/sbin/fsck.ext4 images/rootfs.ext2
    e2fsck 1.42.7 (21-Jan-2013)
    Filesystem did not have a UUID; generating one.
    images/rootfs.ext2: clean, 4616/5120 files, 53171/131072 blocks

    $ ./host/usr/sbin/fsck.ext4 -f images/rootfs.ext2
    e2fsck 1.42.7 (21-Jan-2013)
    One or more block group descriptor checksums are invalid.  Fix<y>? yes
    Group descriptor 0 checksum is 0x4131, should be 0x8bdb.  FIXED.
    [--SNIP--]

So we set an explicitly NULL UUID instead.

0fab0a4afd fs/ext2: bump journal overhead to 1300 blocks
A quick test with a ~3.5MB ext4 filesystem shows that 1081 blocks isn't
enough:

tune2fs 1.42.7 (21-Jan-2013)

Please run e2fsck on the filesystem.

Creating journal inode:
Journal size too big for filesystem.

So bump it a bit. Overestimating the journal size is probably not really
a big deal for the kind of systems using ext3/4 anyway.

69036c20f1 fs/ext2: add ability to build ext3/4 too
Use the host-e2fsprogs to tune2fs the generated rootfs.ext2 image,
and upgrade it to either one of ext2, ext3 or ext4.

Since calling tune2fs may require running e2fsck (tune2fs will warn
to do so when certain FS options are changed), we systematically call
e2fsck. This makes the code path simpler, and as a side-effect checks
that genext2fs did not generate garbage.

In turn, e2fsck will unconditionally add a UUID to the filesystem,
which is bad for reproducibility, so we call tune2fs again to remove
the UUID. This does not require checking the filesystem.

To ensure compatibility of Buildroot's .config, leave ext2 as the
default. Boards' .config can override this at will.

402d1476f7 fs/common.mk: Strip extra whitespace when device table is empty
Since ROOTFS_DEVICE_TABLES is a concatenation of two strings separated by
spaces, there will always be a space in it, which means it's never empty.
Therefore, when testing for empty, the condition never evaluate to false.

The following change fixes this problem; it runs qstrip on the overall
combination of the variables, causing the space to be removed if it's the
only thing left.

847895d295 fs/common.mk: delay evaluation of variables
This makes things easier to understand and more consistent with the pkg-infra.
For example, it removes the need for '$$@' in the CMD variables of fs/*/*.mk.

It also makes it possible to update the variables later, e.g. in the package
override file.

It also makes sure that the date will be recorded correctly in Yann E. Morin's
patch that logs the MESSAGE macros to a file.

The fs/*/*.mk must be updated as well because the '$@' shouldn't be quoted
anymore in the CMD variables or the hooks.

The $(eval ...) for the dependencies is redundant, because the $(ROOTFS_TARGET)
variable is already eval'd. Note that it is only redundant if the evaluation of
the uses of the variable is also delayed.

e1ebae700a fs/common: Create initial console device
A /dev/console node must be present in rootfs when the Linux kernel
boots otherwise the kernel will print the following warning:
"Warning: unable to open an initial console"

This is because when we use an initramfs the /dev directory is not
populated at this point. This can cause problems when a program
(e.g ldso with early debugging enabled) opens a standard file
descriptor for read/write before these descriptors are actually
created by the init process later on.

9226a9907c Warn the user about the usage of output/target as the root filesystem
A very common mistake done by our users is that they use
output/target/ directory as their root filesystem. Even though this is
loudly documented in our Buildroot manual, people don't read
documentation, so it is not sufficient.

This patch adds a text file named
output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM which explains why
output/target isn't appropriate to use as the root filesystem. The
process is:

 * At the beginning of the build, right after the skeleton has been
   copied, support/misc/target-dir-warning.txt is copied to
   output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM

 * In the filesystem images creation code, this file is removed before
   launching fakeroot, and restored right after that, so that this
   file is not present in the generated root filesystem images.

Note that the file has not been added to the default skeleton for two
reasons:

 * It would have annoying to have in our source tree a file named in
   capital letters inside system/skeleton/

 * The proposed way works even if the user uses a custom skeleton.

ff3391323a iso9660 fs: use cpio initrd instead of ext2
The ext2 initrd is pretty broken, because it requires an additional
root=/dev/ram0 command line parameter, and a /init to mount
devtmps that isn't there in out ext2 rootfs.  So just use a cpio
instead.

Note that there is no check if the kernel supports initramfs or the
selected compression method.

Also removed a bit of dead code in iso9660.mk.

6c3e3ad419 New top-level directory: system
This directory groups the following elements:
 * the default root filesystem skeleton
 * the default device tables
 * the Config.in options for system configuration (UART port for
   getty, system hostname, etc.)
 * the make rules to apply the system configuration options

Even though the skeleton and device tables could have lived in fs/, it
would have been strange to have the UART, system hostname and other
related options into fs/. A new system/ directory makes more sense.

As a consequence, this patch also removes target/Makefile.in, which
has become useless in the process.

since 16e7b8255c, nfs-utils has been

3fac21ef8d cpio: fix boot with dynamic /dev
Devtmpfs doesn't get automounted by the kernel when an initramfs is used.
Since cpio archives are used almost exclusively as an initramfs, the same
fix should be applied to it as for the initramfs.

10a130f91e initramfs/init: make sure that 0, 1, 2 fds are available
As the kernel doesn't automatically mount devtmpfs when an initramfs
is used, commit 424888e474 has
introduced a small wrapper script that mounts devtmpfs before starting
the real init.

Unfortunately, the problem is that in this case, the init process runs
without any 0, 1 and 2 file descriptors, so none of the
messages/errors printed by the various initialization scripts can be
seen. This is due to the fact the init process relies on 0, 1 and 2
being opened by the kernel before init is started. However, as
/dev/console isn't present on the filesystem at the time the kernel
tries to open the console to create the 0, 1 and 2 file descriptors,
the kernel fails on this and prints the famous "Warning: unable to
open an initial console".

The proposed workaround is to actually open 0, 1 and 2 to /dev/console
in the wrapper script, right after mounting the devtmpfs filesystem,
and before starting the real init. The "Warning" from the kernel is
still shown, but at least the messages from the init scripts are
visible.

 - devtmpfs method enables this feature in kernel
 - mdev method adds mdev starting script to the file system

 - udev method selects udev for installation

All dynamic methods are based on devtmpfs, so one doesn't need to care

f507921d39 linux: add support for initramfs
In Buildroot, the kernel is built and installed *before* the root
filesystems are built. This allows the root filesystem to correctly
contain the kernel modules that have been installed.

However, in the initramfs case, the root filesystem is part of the
kernel. Therefore, the kernel should be built *after* the root
filesystem (which, in the initramfs case simply builds a text file
listing all files/directories/devices/symlinks that should be part of
the initramfs). However, this isn't possible as the initramfs text
file would lack all kernel modules.

So, the solution choosen here is to keep the normal order: kernel is
built before the root filesystem is generated, and to add a little
quirk to retrigger a kernel compilation after the root filesystem
generation.

To do so, we add a ROOTFS_$(FSTYPE)_POST_TARGETS variable to the
fs/common.mk infrastructure. This allows individual filesystems to set
a target name that we should depend on *after* generating the root
filesystem itself (contrary to normal ROOTFS_$(FSTYPE)_DEPENDENCIES,
on which we depend *before* generating the root filesystem).

The initramfs code in fs/initramfs/initramfs.mk uses this to add a
dependency on 'linux26-rebuild-with-initramfs'.

In linux/linux.mk, we do various things :

 * If BR2_TARGET_ROOTFS_INITRAMFS is enabled (i.e if initramfs is
   enabled as a root filesystem type), then we create an empty
   rootfs.initramfs file (remember that at this point, the root
   filesystem hasn't been generated) and we adjust the kernel
   configuration to include an initramfs. Of course, in the initial
   kernel build, this initramfs will be empty.

 * In the linux26-rebuild-with-initramfs target, we retrigger a
   compilation of the kernel image, after removing the initramfs in
   the kernel sources to make sure it gets properly rebuilt (we've
   experienced cases were modifying the rootfs.initramfs file wouldn't
   retrigger the generation of the initramfs at the kernel level).

This is fairly quirky, but initramfs really is a special case, so in
one way or another, we need a little quirk to solve its specialness.

3754c51560 jffs2: let makedevs create device files
The common filesystem infrastructure in fs/common.mk uses a smart
combination of makedevs and fakeroot to create the device files in the
target filesystem images without being root. This technique is applied
to all filesystem formats that rely on this common infrastructure, and
JFFS2 is one of them.

Therefore, using the -D option of mkfs.jffs2, which allows to specify
a device table, is redundant with the usage of makedevs. And it is
worst than redundant: for some reason, -D does not create all device
files with the correct major and minor numbers, as reported in
bug #1771.

For coherence, we just remove the usage of mkfs.jffs2 -D option, and
rely on makedevs/fakeroot to create the device files.

This commit fixes bug #1771.

initramfs-root but the generated file is rootfs.initramfs

fb951b9342 fs/ext2: fix blocks/inodes calculation
With the ROOTFS_TARGET conversion, EXT2_OPTS gets evaluated very early
(before TARGET_DIR is populated with files), so the calculated
blocks/inodes numbers are wrong.

Fix it by moving the calculation to a shell script wrapper around
genext2fs, so it only gets executed just before genext2fs runs.

7b7e1bc3fb fs/ext2: fix typo
BR2_TARGET_ROOTFS_EXT2_RESBLKS is an int, so test against 0 rather than
the empty string - Otherwise the test is always true and a -m option
without arguments is added to the argument list, causing genext2fs to
get confused.

64ec20e6c0 fs: change the way the device table is configured
Until now, the location of the device table was specified by a
variable in board Makefiles. Unfortunately, this variable is not
accessible from fs/common.mk, since the target/ code is included
*after* fs/common.mk.

Anyway, the general idea is to move away from these boards Makefile,
and provide configuration option for things like the device table
location.

Therefore, this patch adds a BR2_ROOTFS_DEVICE_TABLE option which
allows to specify which device table should be used.
