* system: only expose getty options for busybox and sysvinitGravatar Thomas Petazzoni2018-01-121-0/+4

So, protect those options behind appropriate dependencies on busybox or sysvinit. Fixes #10301. Reported-by: Michael Heinemann <posted@heine.so> Suggested-by: "Yann E.

* system: make systemd work on a read-only rootfsGravatar Yann E. MORIN2017-08-021-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: "Yann E.

* system: separate sysv and systemd parts of the skeletonGravatar Yann E. MORIN2017-08-0211-16/+0
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* package/skeleton: introduce sysv, systemd and none specific skeletonsGravatar Yann E. MORIN2017-08-021-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: "Yann E.

* package/skeleton: split out into skeleton-commonGravatar Yann E. MORIN2017-08-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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/ Signed-off-by: "Yann E.

* package/skeleton: select it rather than default to yGravatar Yann E. MORIN2017-07-311-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: "Yann E.

* package/skeleton: drop dependency on host-mkpasswdGravatar Yann E. MORIN2017-07-311-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: "Yann E.

This is not very consistent. Move setting the getty out of the skeleton and into the package that provides the init system, by registering a per-package target-fialize hook.

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. Signed-off-by: "Yann E.

* system: introduce BR2_SYSTEM_ENABLE_NLSGravatar Thomas Petazzoni2017-07-041-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: "Yann E.

* system: do not overwrite /bin/sh Busybox symlinkGravatar Thomas Petazzoni2017-03-291-1/+0
| | | | | | | | | | | | | | | | | | | | | | 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.

* skeleton: fix permissions on /dev/pts/ptmxGravatar Jan Kundrát2017-03-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

Turns out that musl uses the same zoneinfo format as glibc does. Make it possible to install the TZ info whatever the C library; for musl, use tzdata as for glibc.

* system: move locale purging options to the "System configuration" menuGravatar Thomas Petazzoni2016-08-031-0/+34
| | | | | | | | | | | | | | 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 already have in the "System configuration" menu. Therefore, it makes more sense to have the locale-related options in the "System configuration" menu as well.

| | | | | | | | | | | | | | | | | | | Currently, our /etc/mtab points to /proc/mounts. This was all neat so far, and was good for a sysv-like init system. However, the way today is to point it at /proc/self/mounts, the per-process mount tab. Additionnally, that's what systemd expects. If /etc/mtab is not a symlink to ../proc/self/mounts and the rootfs is readonly, systemd would whine loudly (and a service unit would be marked failed). Since it works well for sysv-like init systems too, just use that. Signed-off-by: "Yann E.

* Makefile: drop ldconfig handlingGravatar Thomas Petazzoni2016-01-031-0/+0
| | | | | | | | | | | | | | | | | | | | | | | | | The ldconfig handling in the main Makefile is utterly broken, as it calls the build machine ldconfig to generate the ld.so.cache of the target. Unfortunately, the format of the ld.so.cache is architecture specific, and therefore the build machine ldconfig cannot be used as-is. This patch therefore simply drops using ldconfig entirely, and removes /etc/ld.so.conf.d/ from the target skeleton. The idea is that all libraries that should be loaded by the dynamic linker must be installed in paths where the dynamic linker searches them by default (typically /lib or /usr/lib). This might potentially break a few packages, but the only way to know is to actually stop handling ldconfig. In order to be notified of such cases, we add a check in target-finalize to verify that there is no /etc/ld.so.conf file as well as no /etc/ld.so.conf.d directory.
