18fa4a32a6 system: allow/disallow root login, accept encoded passwords
Currently, there are only two possibilities regarding the root account:
  - it is enabled with no password (the default)
  - it is enabled, using a clear-text, user-provided password

This is deemed insufficient in many cases, especially when the .config
file has to be published (e.g. for the GPL compliance, or any other
reason.).

Fix that in two ways:

  - add a boolean option that allows/disallows root login altogether,
    which defaults to 'y' to keep backward compatibility;

  - accept already-encoded passwords, which we recognise as starting
    with either of $1$, $5$ or $6$ (resp. for md5, sha256 or sha512).

[yann.morin.1998@free.fr:
  - don't add a choice to select between clear-text/encoded password,
    use a single prompt;
  - differentiate in the password hook itself;
  - rewrite parts of the help entry;
  - rewrite and expand the commit log

e26ec6e45c system: make /bin/sh symlink use relative path
The symlink created by buildroot for /bin/sh is the full path to
a shell.  This does not match what busybox and other Linux
distributions do with using relative path symlinks. When handling
files on the host system this will point to the host system's shell
if present and not the target shell.

This is fixed by changing the /bin/sh symlink to use a relative path.

Fixes #8161.

029179615e system: remove DES password encoding
DES is long dead, it is insecure as hell, and virtually all known
crypt(3) implementations now all support at least md5.

Besides, the character-space of DES-encoded passwords are a sub-set
of the character-space for a clear-text password, so we can't easily
differentiate between the two. Since we're going to change the root
password prompt to support setting encoded passwords (as well as
clear-text passwords), we can't keep DES or we'd be unable to decide
whether we'd need to encode the password or not.

Remove DES encoding altogether (and add a legacy entry). The default is
still md5, and thus there's no backward-compatibility 'select' to add.

131300e6f1 system: run getty on boot console by default
We used to specify explicitly serial port with all its settings
for init to instantiate getty.

This limits usecases when the same one rootfs could be used.

For example following cases won't work well with hardcoded
serial console settings:
 * On the same board other serial port is expected to be used
 * The same rootfs is intended to be used on different boards with
   different serial ports (like ttySx vs ttyAMAx or even ttyx)

With this change by default we rely on "console" specified in
kernel's boot command line.

What is important getty will be set on the last console
specified in bootargs.

For example is a kernel comand line:
--->---
bootargs="... console=tty0 console=ttyS3,115200n8..."
--->---

This now will instantiate serial console on ttyS3 but not on tty0.

Tested with both Busybox and SysV init.

665e13c85e Rename BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS
Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.

As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.

This also helps preparing the addition of other options to select
shared, shared+static or just static.

Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

Not all our shells do install a pointer to /bin/sh. Besides, between

wins the the symlink.

Add a new config choice in the system sub-menu that allows the user to

enabled, default to using dash, a POSIX shell.

Remove the symlink creation from bash.mk at the same time.

Note: for every shell, we select them, except busybox, on which we
depend, on the assumption that we do not want to force busybox in case
the user decided not to enable it.

a8da3cd61a util-linux: libblkid needs fork(), disable on !MMU
The libblkid library in util-linux uses fork. While it seems
potentially possible to disable the parts of the library that use fork
(the only parts using fork are parts related to LVM and Device Mapper,
which are said to be legacy as they are replaced by sysfs based
scanning, instead of having to fork to run a separate process).

However, since libblkid is used by:

 - e2fsprogs, which uses lots of fork all over the place
 - udev, which most likely will also need fork

There is not much point in making libblkid fork-less. As a
consequence, this commit makes util-linux/libblkid unavailable on
non-MMU architectures, and propagates the relevant dependency to the
reverse dependencies of libblkid.

This fixes the e2fsprogs build failure seen on Blackfin. The failure
was due to a configure test of e2fsprogs which was trying to link a
small test program against libblkid, which failed because there was an
undefined reference to fork() in the libblkid code.

2c66e4429d systemd: bump to v207
This patch bumps systemd to v207 but also declares it as a provider for the
udev virtual package.

Starting with systemd 183, udev has been merged into
systemd. The udev daemon is now installed as /lib/systemd/systemd-udevd.
This means that /dev management using udev is only available if systemd
is chosen as init system.

When configuring systemd, the following options are available:

- activation of systemd-journal-gatewayd, to access the journal via
  HTTP.
- activation of extra features like journal compression and sealing.

Support for uClibc has also been removed because:

- upstream has no interest in supporting uClibc.
- using a shrinked libc brings no advantage, given the size of all the
  programs included in Systemd. So using glibc does not matter.

0b90a82cda system: move init system option above /dev management.
The option to choose init system was below the one for /dev management.
As Systemd forces the use of udev, it is logical to swap them.

be084204eb Config.in files: add missing dependencies to toolchain option comments
When a package A depends on config option B and toolchain option C, then
the comment that is given when C is not fulfilled should also depend on B.
For example:

config BR2_PACKAGE_A
	depends on BR2_B
	depends on BR2_LARGEFILE
	depends on BR2_WCHAR

comment "A needs a toolchain w/ largefile, wchar"
	depends on !BR2_LARGEFILE || !BR2_WCHAR

This comment should actually be:

comment "A needs a toolchain w/ largefile, wchar"
	depends on BR2_B
	depends on !BR2_LARGEFILE || !BR2_WCHAR

or if possible (typically when B is a package config option declared in that
same Config.in file):

if BR2_B

comment "A needs a toolchain w/ largefile, wchar"
	depends on !BR2_LARGEFILE || !BR2_WCHAR

[other config options depending on B]

endif

Otherwise, the comment would be visible even though the other dependencies
are not met.

This patch adds such missing dependencies, and changes existing such
dependencies from
  depends on BR2_BASE_DEP && !BR2_TOOLCHAIN_USES_GLIBC
to
  depends on BR2_BASE_DEP
  depends on !BR2_TOOLCHAIN_USES_GLIBC
so that (positive) base dependencies are separate from the (negative)
toolchain dependencies. This strategy makes it easier to write such comments
(because one can simply copy the base dependency from the actual package
config option), but also avoids complex and long boolean expressions.

7f1f9185e7 system: default to devtmpfs for /dev
As discussed on the list, devtmpfs is quite a bit nicer default than
the old static /dev, so change it.

Notice that you NEED to enable CONFIG_DEVTMPFS / CONFIG_DEVTMPFS_MOUNT
in the kernel configuration if you manually build a kernel outside
buildroot, otherwise the rootfs won't work.

ed6912e87d getty: Create specific getty config + cleanups
This commit introduces a specific BR2_TARGET_GENERIC_GETTY configuration flag.
This eliminates the need for checking if BR2_TARGET_GENERIC_GETTY_PORT is an
empty string or not. It also allows hiding various getty options when getty
isn't enabled.

b7c0041c31 kmod: does not support static builds
Since kmod 14, the support for building a static library has been
removed completely from kmod. Therefore, we mark kmod as
!BR2_PREFER_STATIC_LIB, as well as all its reverse dependencies, which
includes the option to use the "udev" /dev management method.

f1f97b3a05 system: add option to pass extra args to post-build and post-image scripts
It can be useful to have different configuration use the same post-build
and/or post-image scripts as they share a common infrastructure, but yet
have minor differentiation.

This option allows passing zero or more additional arguments to each
post-build or post-image script.

The same set of extra arguments are passed to all scripts, it is not
possible to pass different arguments to each script.

[Peter: fix help text, post-image gets called with the images dir]

9fa32ba0b7 Add a post-image script mechanism
Just like we have a post-build script mechanism that gets executed
after the build of all packages but before the creation of the
filesystem images, let's introduce a post-image script mechanism, that
gets executed once all filesystem images have been generated.

This can for example be used to call a tool building a firmware image
from different images generated by Buildroot, or automatically extract
the tarball root filesystem image into some location exported by NFS,
or any other custom action.
