Lubomir Rintel 4032267507 system/skeleton: drop PAGER from /etc/profile
We couldn't track down the reason why the profile sets $PAGER other
than that it has always been there.

However, it defeats pager autodetection by various tool (systemctl,
nmcli, etc.) that would otherwise prefer less to more, in case both
were available.

Let's drop it. My desktop Linux distro (Fedora) doesn't seem to set it
either and the universe doesn't seem to have collapsed yet.

Michał Łyszczek eb77734d11 system/Config.in: add new init - openrc
This is very basic settings for openrc init.

* system/Config.in
  Allows to select openrc as init system (which auto selects
  openrc-skeleton and openrc package).

* package/ifupdown-scripts/Config.in
  openrc has its own service to bring up/down interfaces, so
  ifupdown-scripts should not be enabled when openrc is enabled to
  prevent service clash.

Arnout Vandecappelle (Essensium/Mind) be8d11c7e5 system/skeleton: remove password expiration from shadow
The fields in /etc/shadow were set as follows:

root::10933:0:99999:7:::

This sets the date of last password change to Jan 1, 2000, the minimum
password age to 0 days, the maximum password age to near-infinity, and a
warning period of 7 days. In practice, this means the password never
expires. So all of this is quite useless.

On the other hand, mkusers creates lines without all of these options.
It just sets ::::: which disables password expiration completely.

To make things consistent, do the same for the skeleton entries.

Markus Mayer df20a836c1 skeleton: use BR2_SYSTEM_DEFAULT_PATH as default PATH
We substitute the path specified in system/skeleton/etc/profile with
the path specified in the configuration variable
$(BR2_SYSTEM_DEFAULT_PATH).

$(BR2_SYSTEM_DEFAULT_PATH) is a Kconfig string, so it is already
double quoted. This means that export PATH=value will now be export
PATH="value" in /etc/profile, which is perfectly fine.

Matt Weber bf3626002f system cfg: remove mkpasswd MD5 format option
As SHA256 is now default, removing weak MD5 option.  C libraries now
all support the SHA methods.
    glibc 2.7+
    uclibc (bdd8362a88 package/uclibc: defconfig: enable sha-256...)
    musl 1.1.14+

One issue this would prevent, is a host tool issue with a FIPS enabled
system where weak ciphers/methods are disabled. It seems the crypt(3)
call is impacted by /proc/sys/crypto/fips_enabled (per crypt(3) man
page). It results in mkpasswd returning "(EPERM) crypt failed."
Rather then create a Buildroot host dependency check, this patch
removes the potential corner case from being selected.

Yann E. MORIN 0d61846b5f package/systemd: needs glibc
Since version v239, systemd-nspawn unconditioanlly uses prlimit(2),
which is not implemented in uClibc-ng. systemd-nspawn can not be
disabled.

This makes systemd glibc-only again.

After a bit of discussion with upstream (om IRC), it looks very
improbable that they accept a patch making systemd-nspawn optional.
They would probably consider a patch that provides that syscall wrapper
if it is missing, though, but that's less trivial...

Thomas Petazzoni 3c631c741c system: update Config.in comment about systemd dependencies
In commit 879fa7f82a, the
BR2_INIT_SYSTEMD option was changed to allow selecting with a uClibc
toolchain. Unfortunately, the corresponding Config.in comment, which
was already bogus, was not updated to take into account the numerous
dependencies of BR2_INIT_SYSTEMD.

Due to this, even if you have uClibc enabled, the BR2_INIT_SYSTEMD
option may not be visible, and the Config.in comment may also not be
visible, leaving the user in the dark.

This commit fixes the dependencies of the Config.in comment so that
they match the one of the BR2_INIT_SYSTEMD option.

Peter Korsgaard 2b21ba2fac skeleton: add /dev/fd, /dev/std{in, out, err} symlinks for static /dev on readonly rootfs
Some applications, e.g. bashs process subsitution feature, rely on the
convention of `/dev/fd` being a symbolic link to `/proc/self/fd`.

When a static /dev is used on a readonly rootfs then the runtime ln
invocations in the inittab will fail, so we need to add the symlinks at
build time.  Makedevs doesn't support creating symlinks, so instead add the
symlinks to the default skeleton.

For non-static /dev setups, the kernel will mount devtmpfs which shadows the
/dev of the rootfs, but then the runtime ln invocations in inittab will
create the symlinks.

Yann E. MORIN 26085bbbd5 system: make systemd work on a read-only rootfs
When the rootfs is readonly, systemd will expect /var to be writable.
Because we do not really have a R/W filesystem to mount on /var, we make
it a tmpfs [*], and use the systemd-tmpfiles feature to populate it with
"factory" defaults.

We obtain those factory defaults by redirecting /var to that location at
build time, using a symlink /var -> /usr/share/factory which is the
location in which systemd-tmpfiles will look for when instructed to
"recursively copy" a directory.

With a line like:

    C /var/something - - - -

it will look for /usr/share/factory/something and copy it (recursively
if it is a directory) to /var/something, but only if it does not already
exist there.

We also mark this copy with the exclamation mark, as it is only safe to
copy on boot, not when changing targets.

To be noted: the real format for such lines are:

    C /var/something - - - - /from/where/to/copy/something

But if the source is not given, then it is implicitly taken from
/usr/share/factory (which in our case is as-good a location as whatever
else, so we use it, and thus we need not specify the source of the
copy).

Note that we treat symlinks a little bit specially, by creating symlinks
to the factory defaults rather than copying them.

Finally, /var at build time is a symlink, but at runtime, it must be a
directory (so we can mount the tmpfs over there). We can't change that
as a target-finalize hook, because:

  - some packages may want to set ownership and/or access rights on
    files or directories in /var, and that only happens while assembling
    the filesystem images; changing /var from a symlink to a (then
    empty) directory would break this;

  - /var would be a directory on sub-sequent builds (until the next
    "make clean").

Instead, we use the newly-introduce pre- and post-rootfs command hooks,
to turn /var into a directory before assembling the image, and back to a
symlink after assembling the image.

[*] People who want the factory-defaults only on first boot will have
    to tweak the fstab to mount something else than a tmpfs on /var.

Yann E. MORIN 76fc9275f1 system: separate sysv and systemd parts of the skeleton
For systemd, we create a simple /etc/fstab with only an entry for /, as
systemd otherwise automatically mounts what it needs where it needs it.

systemd does not like that the content of /var be symlinks to /tmp,
especially journald that starts before /tmp is mounted, and thus the
journal files are hidden from view, which causes quite a bit of fuss...

Instead, move the current /var to a sysv-only skeleton.

systemd at install time will create the /var content it needs, so we
just create an empty /var for systemd.

systemd would create /home and /srv at runtime if they are missing, but
it is better to create them right now, to simplify supporting systemd on
a RO filesystem in the (near) future.

Yann E. MORIN c0fd0ac655 package/skeleton: introduce sysv, systemd and none specific skeletons
Currently, we use the same skeleton for sysv-like init systems and
systemd, even though systemd has some peculiarities that makes our
default skeleton unfit.

So, we'll need to provide different skeletons (really, only part of
it) for sysv-like and systemd. In addition, in order to support the
"no init system" (BR2_INIT_NONE) use case, we introduce a "none"
skeleton.

Introduce three new skeleton packages, aptly named skeleton-sysv,
skeleton-systemd and skeleton-none. All three are providers of the
skeleton virtual package, in lieu of the skeleton-common package,
which is now a simple dependency of all three new skeletons.

Those packages are empty for now. In followup changes:
  - sysv-specific stuff will be moved out of skeleton-common and into
    skeleton-sysv;
  - systemd-specific stuff will be added to skeleton-systemd.

Yann E. MORIN 120307520f package/skeleton: split out into skeleton-common
Move all the handling of the default skeleton into a new package,
skeleton-common.

We don't name it skeleton-default, because it will be further split
later, into a skeleton for sysv and another for systemd, with some parts
still common between the two. So just name it skeleton-common right now;
this will save us a rename later.

While we're at it, also assign to SKELETON_COMMON_TARGET_FINALIZE_HOOKS
instead of directly to the global FINALIZE_HOOKS. Therefore, we don't
need to do all of that in a condition BR2_PACKAGE_SKELETON_COMMON==y.

Note: it would be technically sound to move the skeleton files together
within a sub-directory of the skeleton-common package. However, we refer
the user to those files, from various locations (manual, packages). It
will indeed be easier for the user to find those files in
system/skeleton/ rather than in package/skeleton-common/skeleton/

Yann E. MORIN 10ac06496c package/skeleton: select it rather than default to y
Our current skeleton is tailored to sysv-like init systems; it is not
fit for systemd-based systems. So, in upcoming changes, we'll add
another skeleton for systemd.

This means we can no longer have the current skeleton default to 'y', or
it would be enabled also for systemd, which would be incorrect.

So, we remove the default to 'y' but have it selected by the default
skeleton choice.

However, we do not yet have a way to directly build (really, install)
the custom skeleton, it is built (really, installed) as a dependency of
the default skeleton. So we must also forcibly select the default
skeleton when using a custom one.

Until we have the means to do only one or the other; i.e. when we have a
virtual skeleton.

Yann E. MORIN 7c1692df6f package/skeleton: drop dependency on host-mkpasswd
Setting the root pasword is done in a target-finalize hook, so we do not
need to enforce a dependency from the skeleton onto host-mkpasswd.

Dropping that dependency will simplify making skeleton a virtual
package (in up-coming changes).

Instead, it is now selected as any other package. As such, it is
guaranteed to be built before target-finalize.

This however introduces a slight change in behaviour: previously,
host-mkpasswd would only be built if we needed to hash the root password
from its plain-text value. Now, host-mkpasswd is always built as soon as
the root password is non-empty, even if already pre-hashed.

Since host-mkpasswd is a really tiny weeny package bundled in Buildroot,
with only two C files, built as a single unit with a single gcc call,
the overhead is really minimal. Compared to the simplifications this
will allow in the skeleton packages (plural: common, sysv, systemd,
custom) to come, this overhead is acceptable.

Yet another simplification, even if small, to ease providing multiple
skeletons.

Yann E. MORIN 5fb1b86782 package/ifupdown-scripts: new package
The ifupdown scripts can be used independently of the init system, be it
sysv, busybox or systemd; they could even be used when there is no init
system (i.e. the user is providing his own).

Currently, those ifupdown scripts are bundled in the skeleton.

But we soon will have a skeleton specific to systemd, so we would be
missing those scripts (when systemd-networkd is not enabled).

So, move those scripts to their own package.

To keep the current behaviour (before it is changed in future commits),
we make that package default to y, but depend on the default skeleton.

Instead of being a target-finalize hook, the scripts are installed as
any other package are, with a package install-target command.

Thomas Petazzoni dc057d2865 system: introduce BR2_SYSTEM_ENABLE_NLS
Until now, the option BR2_ENABLE_LOCALE was more-or-less controlling
whether NLS support was enabled in packages. More precisely, if
BR2_ENABLE_LOCALE=y, we were not doing anything (so some packages
could have NLS support enabled, some not). And only when
BR2_ENABLE_LOCALE was disabled we were explicitly passing
--disable-nls to packages.

This doesn't make much sense, and there is no reason to tie NLS
support to locale support. You may want locale support, but not
necessarily NLS support. Therefore, this commit introduces
BR2_SYSTEM_ENABLE_NLS, which allows to enable/disable NLS support
globally. When this option is enabled, we pass --enable-nls to
packages, otherwise we pass --disable-nls.

In addition, when this option is enabled and the C library doesn't
provide a full-blown implementation of gettext, we select the gettext
package, which will provide the full blown implementation.

It is worth mentioning that this commit has a visible impact for users:

 - Prior to this commit, as soon as BR2_ENABLE_LOCALE=y, packages
   *could* provide NLS support. It was up to each package to decide
   whether they wanted to provide NLS support or not (we were not
   passing --enable-nls nor --disable-nls).

 - After this commit, it's BR2_SYSTEM_ENABLE_NLS that controls whether
   NLS is enabled or disabled, and this option is disabled by default.

Bottom line: with the default of BR2_SYSTEM_ENABLE_NLS disabled, some
packages may lose NLS support that they used to provide. But we
believe it's a reasonable default behavior for Buildroot, where
generally NLS support is not necessary.

Yann E. MORIN e7e526e910 system: require a timezone to be set
Even though no timezone implicitly means UTC, systemd is not all that
happy when it does not have a timezone set. This is all fine on a RW
filesystem because systemd will create a symlink on its own (to
Etc/UTC), but not so much on a RO filesystem, causing all kind of
issues at boot time (up to the point that the system is unusable).

We fix that by requiring that the timezone is actually set. The check is
done by verifying that the timezone file is an actual file; if not set,
the test would find a directory and would thus fail.

Update the help entry accordingly.

Also fix indentation in tzdata.

Thomas Petazzoni fc91501e6b system: do not overwrite /bin/sh Busybox symlink
The BR2_SYSTEM_BIN_SH hidden option defines to what binary the /bin/sh
symlinks should point to. If busybox is chosen, then /bin/sh is created
to point to /bin/busybox.

This works fine with the default installation mode of Busybox, but it
fails with the upcoming "individual binaries" mode, in which each applet
is installed as its own binary, and /bin/busybox doesn't exist: we get
/bin/sh as a broken symlink to /bin/busybox.

Since Busybox already installs its own /bin/sh symlink, properly
pointing to /bin/ash or /bin/hush depending on the selected shell, it
doesn't make sense for the BR2_SYSTEM_BIN_SH logic to override
this. Just let Busybox install its own /bin/sh by making
BR2_SYSTEM_BIN_SH empty when Busybox shell is selected as /bin/sh.

Jan Kundrát 8196b299ba skeleton: fix permissions on /dev/pts/ptmx
Without this patch, it is not possible to allocate PTYs when a generated
rootfs image with a recent glibc and systemd is launched as a container  on
an RHEL7 system via machinectl/systemd-nspawn. The container boots, but
`machinectl login mycontainer` fails. The culprit is /dev/pts/ptmx with
0000 perms.

On a typical system, there are two `ptmx` devices. One is provided by the
devpts at /dev/pts/ptmx and it is typically not directly accessed from
userspace. The other one which actually *is* opened by processes is
/dev/ptmx. Kernel's documentation says these days that /dev/ptmx should be
either a symlink, or a bind mount of the /dev/pts/ptmx from devpts.

When a container is launched via machinectl/machined/systemd-nspawn, the
container manager prepares a root filesystem so that the container can live
in an appropriate namespace (this is similar to what initramfs is doing on
x86 desktops). During these preparations, systemd-nspawn mounts a devpts
instance using a correct ptmxmode=0666 within the container-to-be's
/dev/pts, and it adds a compatibility symlink at /dev/ptmx. However, once
systemd takes over as an init in the container,
/lib/systemd/systemd-remount-fs applies mount options from /etc/fstab to
all fileystems. Because the buildroot's template used to not include the
ptmxmode=... option, a default value of 0000 was taking an effect which in
turn led to not being able to allocate any pseudo-terminals.

The relevant kernel option was introduced upstream in commit 1f8f1e29 back
in 2009. The oldest linux-headers referenced from buildroot's config is
3.0, and that version definitely has that commit. Mount options that are
not understood by the system are anyway ignored, so backward
compatibility is preserved.

This commit updates comments in Config.in for BR2_USE_WCHAR for reverse
dependencies of util-linux which directly uses wchar now or when it is
pulled from other dependencies.

eudev doesn't use wchar directly, but needs C99 compiler. Autotools

Peter Korsgaard 9c67af2c52 system/skeleton: use uid/gid 65534 for nobody/nogroup
As recently discussed on lwn.net: https://lwn.net/Articles/695478/

The kernel has special behaviour for uid/gid 65534:

1. The kernel maps UIDs > 65535 to it when some subsystem/API/fs
   only supports 16bit UIDs, but a 32bit UID is passed to it.

2. it's used by the kernel's user namespacing as the internal UID
   that external UIDs are mapped to that don't have any local mapping.

3. It's used by NFS for all user IDs that cannot be mapped locally if
   UID mapping is enabled.

Most distributions already map (or are in the progress of changing)
nobody/nogroup to the 65534 uid/gid, so lets do so as well.

The options to purge locales and to generate locale data are currently
located in the toolchain menu. However, these options are not really
related to the toolchain per-se, they are more system-level
configuration options, much like the timezone selection option we

Therefore, it makes more sense to have the locale-related options in
the "System configuration" menu as well.
